SECR · Scope and thresholds
SECR thresholds: who reports, really
The SECR reporting threshold for an unquoted company or LLP is two of three: more than £36 million turnover, more than £18 million balance sheet total, more than 250 employees (SI 2008/410 Sch 7 ¶20B).
Quoted companies skip the test entirely and report at any size.
Since 6 April 2025 those figures no longer match the Companies Act size test, so a company now “medium-sized” for its accounts can still owe an energy and carbon report (SI 2024/1303 EM ¶6.7).
The answer
A two-of-three test, and quoted companies skip it
Three populations report under SECR, and only two of them are decided by size.
Quoted companies are in scope whatever their size, because Part 7 of Schedule 7 applies on listing status alone.
Unquoted companies are in scope if they are large under Part 7A.
Large LLPs are in scope on the same numbers, reached by a separate route through regulation 12B of the LLP Regulations.
The test is written as an exemption: an unquoted company is outside SECR for a year if it meets at least two of turnover not more than £36 million, balance sheet total not more than £18 million, and not more than 250 employees.
Turn it round and it is the sentence most readers want: you are in scope if you exceed at least two of the three.
The streamlined energy and carbon reporting guide explains what the regime is for; this page is about who it catches.
The word that decides it
“£36 million or more” is the summary. The regulation says otherwise.
Many accounts of SECR scope, including one of DESNZ’s own, write the test as “£36 million or more”.
Paragraph 20B(2) is drafted the other way round: it lists who is exempt, and each condition reads “not more than”.
| Document | How it states the threshold | Effect at exactly £36m |
|---|---|---|
| SI 2008/410 Sch 7 ¶20B(2) — the regulation | "Turnover — not more than £36 million" | Meets the exemption condition; in scope needs more than £36m |
| DESNZ, 2026 post-implementation review | "turnover of £36 million or more … and/or 250 or more employees" | Treated as in scope — wider than the regulation |
| DfE, SECR for academy trusts (updated 12 Aug 2026) | "turnover (or gross income) of more than £36 million" | Matches the regulation |
A company with turnover of exactly £36 million meets that condition, because £36 million is not more than £36 million.
A company with exactly 250 employees meets that one too.
Read as the 2026 review writes it, both companies are in scope on those two conditions; read as the regulation writes it, both are exempt.
The review also writes “and/or”, where the regulation asks for two or more of the three.
Very few companies sit exactly on £36,000,000, so this is a boundary case rather than a widespread problem.
It matters because the boundary is where an argument with an auditor happens, and because a page that repeats “or more” is repeating a summary rather than the instrument.
Where the two differ, the statutory instrument governs; our reading, not advice, is to write the test as exceeding two of the three and to take advice if your figures land on a line.
Entering and leaving
One big year does not put you in, one small year does not get you out
The threshold test is not a snapshot.
Paragraph 20B(1) exempts a company in a later financial year if the conditions are met in that year and the preceding one, or if they are met in one of the two years and the company was exempt the year before.
In its first financial year a company is tested on that year alone.
The same construction sits in section 465 of the Companies Act, and it catches people in both directions.
Growth into scope takes two years, and so does exit from it; the year you notice is rarely the year that decided it.
Only turnover is pro-rated for a financial year that is not twelve months long; the balance sheet total is gross assets, and employees are the monthly average of persons employed under contracts of service (¶20B(3)).
The SECR requirements set out what the first year in scope obliges you to publish, and when prior-year comparatives begin.
An exempt company that grows
- Year 1Over two thresholds
Still exempt: it met the conditions the year before and was exempt (¶20B(1)(b)(iii)).
- Year 2Over them again
In scope: no limb of the exemption is met. The disclosures go in this year’s report.
- Year 3Back under
Still reporting: it meets the conditions this year but was not exempt last year and did not meet them then.
- Year 4Under again
Exempt: the conditions are met in this year and the year before (¶20B(1)(b)(i)).
Measuring each limb
What counts as turnover, assets and employees for the SECR test
The thresholds are only as good as the figures fed into them, and paragraph 20B(3) fixes how each one is measured. Each has a common misreading.
| Limb | What ¶20B(3) says | The common mistake | Worked figure |
|---|---|---|---|
| Turnover | Proportionately adjusted where the financial year is not a year | Using the raw figure for a 15-month or 9-month period | £40m over 15 months is £32m for the test |
| Balance sheet total | The aggregate of the amounts shown as assets in the balance sheet | Using net assets, after liabilities | £25m of assets and £12m of liabilities is £25m, not £13m |
| Employees | The monthly average of persons employed under contracts of service | Counting full-time equivalents, or the year-end headcount | 12 months of 240, 260, 250 … averaged; part-timers count as people |
Only turnover is pro-rated, which matters in a first year or after a change of year-end.
A 15-month first period with £40 million of turnover is £32 million for the test, because 40 × 12 ÷ 15 is 32, so on turnover alone that company has not exceeded the limit.
The balance sheet total is gross: every asset shown on the balance sheet, with nothing taken off for what the company owes.
A property-holding or asset-heavy company can therefore exceed £18 million of balance sheet total with modest net assets, which is the limb most easily misread.
Employees are people, not full-time equivalents: the rule counts the persons employed under contracts of service in each month and averages the twelve monthly totals.
Contractors and agency staff engaged through a third party are not employed by the company under a contract of service, so they do not count towards its own figure.
A group applies the same rules to each member and aggregates them, net or gross, under ¶20C, taking a subsidiary’s figures from its own accounts for the relevant year.
The same three measurement rules sit in the Companies Act’s size tests, which is why an accounts team usually already has the figures; what differs is the limits they are compared with.
Your own figures
Work the SECR reporting threshold against your numbers
The check applies the regulation’s own test rather than the shorthand version of it.
It asks whether you are quoted, whether a parent’s group report already covers you, and then takes two years of turnover, balance sheet total and headcount.
It uses “not more than”, because that is how paragraph 20B is drafted, and it tells you which limb of the two-year rule decided the answer.
Nothing you enter leaves your browser.
It answers the size question only: a low-energy year, the prejudice relief or an overseas parent can each change the outcome, and each has its own section below.

Six companies, one test
The SECR threshold, worked through six cases
The rule is easier to apply than to state. Each case below is a first financial year, so the two-year rule does not yet bite, and each answer names the provision that decides it.
| Company | Turnover | Balance sheet | Employees | In scope? | Why |
|---|---|---|---|---|---|
| Unquoted manufacturer | £40m | £22m | 180 | Yes | Exceeds two limbs (turnover, balance sheet): the ¶20B(2) exemption fails |
| Unquoted services firm | £36m | £18m | 250 | No | Exactly on each limit is "not more than" each limit: it satisfies all three conditions |
| Unquoted retailer | £120m | £9m | 240 | No | Exceeds only turnover; it satisfies two conditions, which is enough for the exemption |
| AIM-quoted software company | £38m | £25m | 120 | Yes | AIM is unquoted (CA 2006 s.385), so the size test applies, and it exceeds two limbs |
| Main-market plc | £4m | £3m | 30 | Yes | Quoted: Sch 7 Part 7 ¶15 applies with no size test |
| LLP | £37m | £19m | 90 | Yes | SI 2008/1911 reg 12B applies the same figures to LLPs, and it exceeds two |
Two of the six surprise people.
The services firm sitting exactly on £36m, £18m and 250 is outside SECR, because “not more than” includes the limit itself; the shorthand “£36m or more” would put it in.
The retailer with £120m of turnover is outside too, because a high figure on one limb is not enough: the test counts limbs, not size.
The AIM company is the most common misreading in the other direction, with advisers treating AIM as quoted and assuming every AIM company reports whatever its size.
It is unquoted, so it reports only if it exceeds two of the three limits, as this one does.
Groups work the same way on consolidated figures, with the net or gross group limits in ¶20C, and the group section below covers when a subsidiary can shelter under its parent’s report.
For a second or later year, run the checker above with both years’ figures, because the answer can differ from a single-year reading.
When an in-scope company files
SECR has no deadline of its own: it rides the accounts
Crossing the threshold does not start a separate SECR filing calendar.
The energy and carbon information goes into the directors’ report, and it is delivered with the annual accounts on the Companies Act filing deadline.
That is nine months after the year end for a private company and six months for a public one, counted month-end to month-end under section 443.
An LLP files nine months after its year end, under the LLP regulations.
A first set of accounts covering more than twelve months has its own rule, and the calculator beside this text applies it.
Weekends and bank holidays do not move the date.
The practical consequence is that the data deadline is earlier than the filing deadline: the figures have to be settled before the directors approve the report, and before any auditor reads it for consistency.
What the report must contain, line by line, is in the SECR reporting template.

6 April 2025
The SECR company size thresholds no longer match the Companies Act
For financial years beginning on or after 6 April 2025, SI 2024/1303 raised the Companies Act monetary size thresholds by about half.
A company is now large for its accounts only above £54 million of turnover and £27 million of balance sheet total; SECR did not move at all.
| Measure | Companies Act "large" (accounts) | SECR "large" (energy and carbon report) |
|---|---|---|
| Turnover | More than £54m | More than £36m |
| Balance sheet total | More than £27m | More than £18m |
| Employees | More than 250 | More than 250 |
| Group turnover (net / gross) | £54m / £64m | £36m / £43.2m |
| Group balance sheet (net / gross) | £27m / £32m | £18m / £21.6m |
| Test | Two of three | Two of three, over two consecutive years |
| Where it lives | CA 2006 ss.465–466, as amended by SI 2024/1303 reg 10 | SI 2008/410 Sch 7 ¶¶20B–20C; SI 2008/1911 reg 12B |
Why SECR did not move, precisely
This is usually explained as a saving provision, and that explanation is wrong.
SI 2024/1303 has one transitional provision, regulation 3, and it deals only with how prior years are re-tested against the new figures.
Where it touched Schedule 7 at all, regulation 5(3) omitted “Parts 3 and 4” only; Part 7A was left alone.
SECR was unaffected for a simpler reason: Parts 7 and 7A carry their own threshold table and do not cross-refer to sections 465 to 467, so an amendment to those sections cannot reach them.
The Explanatory Memorandum says so in terms at ¶6.7: the Regulations “do not affect the streamlined energy and carbon reporting (‘SECR’) requirements in Parts 7 and 7A of Schedule 7” or regulation 12B of the LLP Regulations.
The Financial Reporting Council’s threshold summary, announced in its March 2025 news release and held in its publications library, answers the question the same way: “No, these Regulations do not affect the streamlined energy and carbon reporting (SECR) requirements.”
DESNZ then restated the old figures in its 2026 review, thirteen months after the uplift.
One trap runs the other way: GOV.UK’s 2019 SECR guidance describes the LLP threshold as “based on sections 465 and 466 of the Companies Act”; follow that cross-reference today and you land on £54m / £27m, which is not the SECR test.
The cohort in between
Who is actually caught by the gap
The exposure sits with companies whose turnover is between £36 million and £54 million, or whose balance sheet total is between £18 million and £27 million, with 250 or fewer employees.
They are medium-sized for accounts and large for energy and carbon reporting at the same time, on the same set of accounts.
It follows directly from ¶6.7 of the Explanatory Memorandum; it is not a drafting accident anybody has disowned.
It is easy to miss because the person who tells a company it has become medium-sized is usually its accountant, and the subject is usually audit exemption.
The energy and carbon disclosures live in the directors’ report, which is filed at Companies House and is public (SI 2018/1155).
A dropped disclosure is therefore visible to anyone who reads the filing, including a customer running supplier due diligence.
SECR is one of several UK regimes whose scope tests do not line up; the wider map of ESG reporting requirements in the UK sets the others beside it, and the UK carbon reporting requirements page narrows that to carbon.
“We are medium-sized now” is not a SECR exit.
Scope is tested against the 2018 regime’s own numbers, which the 2025 uplift did not touch.
The other population
Who must report SECR when no threshold applies
A quoted company is in scope at any size, and “quoted” is narrower than most people assume.
Section 385 of the Companies Act defines it as a company whose equity share capital is on the official list, officially listed in an EEA State, or admitted to dealing on the New York Stock Exchange or Nasdaq.
AIM is not the official list, so an AIM company falls into SECR only through the large-unquoted route.
That changes what it reports as well as whether it reports: an AIM company in scope files the unquoted set, based on UK energy use and including the transport-fuel limb.
A very small listed company, by contrast, reports its emissions and energy use worldwide, and states what proportion relates to the UK and offshore area (Sch 7 ¶15(3B)–(3C)).
Its only size-based way out of the figures is the 40,000 kWh relief, which for a quoted company has no UK limit.
The gases counted are those defined in section 92 of the Climate Change Act 2008, which Schedule 7 ¶20 adopts for “emissions”.
| Where the shares are | SECR route |
|---|---|
| Official list (London main market) | Quoted — in scope at any size |
| Officially listed in an EEA State | Quoted — in scope at any size |
| NYSE or Nasdaq | Quoted — in scope at any size |
| AIM | Unquoted — tested on £36m / £18m / 250 |
| Not listed | Unquoted — tested on £36m / £18m / 250 |
Organisation by organisation
Who must report under SECR, one type at a time
“Who has to report under SECR?” is a question about legal form before it is a question about size.
SECR attaches to two documents: the directors’ report of a company, under Schedule 7 to SI 2008/410, and the energy and carbon report of an LLP, under SI 2008/1911.
An organisation that produces neither document has no SECR duty, however much energy it uses.
Among companies, listing status comes next: a quoted company reports at any size, and every other company takes the size test.
Within groups, the question becomes whether a UK parent’s group report covers the subsidiary, which it can only do if the parent prepares one.
The register beside this text sorts the common cases by answer.
SECR has no sector test: a bank and a manufacturer of the same size and form have the same duty, and what differs is how much energy there is to report.

Group structures
A subsidiary can be exempted, but only into a report that exists
Where a parent prepares a group directors’ report or group energy and carbon report that includes the subsidiary, the subsidiary does not repeat the disclosures in its own report.
The shelter in paragraph 20A(2) is conditional, and a group that changes one company’s year end can break it without noticing.
Parent companies are tested on the group’s aggregate figures under paragraph 20C: not more than £36 million net or £43.2 million gross of turnover, and not more than £18 million net or £21.6 million gross of balance sheet total.
A group may use either the net or the gross figure for each limb, and gross, before intra-group eliminations, is always the larger number.
For a subsidiary whose year end differs from the parent’s, the figures are those for its financial year ending last before the parent’s year end.
Overseas parents
The shelter works by pointing at a UK group report that complies with Schedule 7.
A parent incorporated outside the UK prepares no directors’ report under the Companies Act, so for most overseas-parented groups there is nothing for the shelter to point at.
Our reading is that a UK subsidiary exceeding two of the three thresholds reports in its own right, whatever its parent publishes elsewhere; a global sustainability report is not a substitute for content required in a filed directors’ report.
DESNZ’s 2026 review names group reporting boundaries among the areas where updated guidance may be consulted on.
The ¶20A(2) conditions — all must hold
- 01The company is a subsidiary undertaking at the end of the financial year
- 02It is included in the group report of a parent undertaking
- 03The parent’s financial year ends at the same time as, or before, the subsidiary’s
- 04The group report complies with Schedule 7 without relying on the seriously prejudicial relief
The relief that rarely works
The SECR exemptions are three reliefs, and each needs a statement
None of the three takes a company out of SECR; each lets it leave information out, provided the report says so.
| Relief | Unquoted company or LLP | Quoted company | What the report must say |
|---|---|---|---|
| Low energy use | 40,000 kWh or less consumed in the United Kingdom in the period (¶20D(7)(a)) | 40,000 kWh or less consumed in the period — no UK limit (¶15(5)(a)) | That the information is not disclosed for that reason |
| Seriously prejudicial | Disclosure would, in the directors’ opinion, be seriously prejudicial to the company (¶20D(7)(b)) | The same (¶15(5)(b)) | That the information is not disclosed for that reason |
| Not practical to obtain | Applies only to the extent it is practical to obtain the information (¶20D(6)) | The same (¶15(4)) | What information is not included, and why |
The low-energy threshold is “40,000 kWh” in the regulation, never “less than 40 MWh”; the 2019 guidance writes it as 40MWh and also adds an offshore limb the paragraph does not contain.
“Energy” in the test means all forms of energy products (¶20), which is wider than the gas, electricity and transport fuel an unquoted company has to report.
For a company already exceeding two of £36 million turnover, £18 million of assets and 250 employees, the ceiling is hard to meet unless the entity has almost no operations of its own.
The prejudice relief is rarely used, because the disclosures are energy volumes and emissions totals rather than anything commercially granular.
Where a parent relied on it, the group report no longer shelters its subsidiaries.
There is no exemption for a first year, for a company that has just crossed a threshold, or for a company that finds the data difficult: difficulty triggers the “not practical” statement, which is an explanation in the report, not a way out of it.
Partnerships
An LLP reports on the same numbers, through a different document
Large LLPs are in scope on exactly the same £36m / £18m / 250 figures and the same two-year machinery.
Regulation 12B applies a modified section 415A of the Companies Act to LLPs and expressly omits Schedule 7 paragraphs 20B and 20C for them, so citing ¶20B as the LLP threshold is citing the wrong provision.
An LLP has no directors’ report, so its members prepare a separate energy and carbon report.
It is approved by the members and signed on their behalf by a designated member.
An LLP has no strategic report either, so the option some companies use of moving energy and carbon content into the strategic report is not open to it.
Parent LLPs preparing group accounts prepare a group energy and carbon report on the same basis as a parent company.
The content is the same as a large unquoted company’s.
Charities and the public sector
Charitable companies are tested; public bodies are outside
SECR reaches only companies and LLPs; the instruments contain no separate charity, academy or public-sector population.
A charitable company is a company, and is tested on the same two-of-three route as any unquoted company.
The Department for Education’s guidance for academy trusts states the turnover limb as “turnover (or gross income) of more than £36 million” and puts the disclosures in the directors’ (trustees’) report.
An unincorporated charity is not a company and is therefore outside SECR entirely, whatever its size.
Public bodies, NHS bodies, universities that are not companies, and local authorities sit outside SECR unless they operate a company that meets the test in its own right.
Five size tests, side by side
The SECR thresholds against every other UK disclosure threshold
UK reporting has several size tests that look alike and are not. Each row below is its own instrument, and a company can be inside one and outside the next.
| Regime | The test | Structure | Measured on |
|---|---|---|---|
| SECR (unquoted companies, LLPs) | More than £36m turnover, £18m balance sheet, 250 employees | Exceed two of three, two-year rule | Financial year |
| Companies Act: medium-sized | Not more than £54m turnover, £27m balance sheet, 250 employees | Meet two of three, two-year rule | Financial year |
| ESOS large undertaking | At least 250 persons, or more than £44m turnover and more than £38m balance sheet | Headcount alone, or both money limbs | The qualification date, 31 December 2026 |
| Companies Act climate disclosures | More than 500 employees, plus a listing, AIM, banking or insurance status, or turnover over £500m | Headcount plus a status or turnover | Financial year |
| UK SRS (FCA rules) | No size test: a listing in UKLR 6, 14, 15, 16 or 22 | Listing category | Accounting periods from 1 January 2027 |
The SECR test and the Companies Act medium-sized test share a structure and an employee figure, and nothing else since April 2025.
A company with £45 million of turnover and a £20 million balance sheet is medium-sized for its accounts and still inside SECR, because it exceeds two of SECR’s older limits.
ESOS works differently in three ways: headcount alone can qualify, the money limbs must both be exceeded, and the test is taken on one day rather than over a financial year.
The Companies Act climate disclosures start at more than 500 employees and add a status or a turnover test, so most SECR companies are outside them.
UK SRS has no size threshold at all for listed companies: the FCA considered one in its final rules and rejected it, reasoning that climate exposure turns on business model and industry, not size.
The practical consequence is that a company near any of these lines should test each one separately, on its own measure and its own date.
The other energy regime
Qualifying for ESOS tells you nothing about SECR
The two regimes are routinely described together, and their scope tests are different logic, not just different numbers.
ESOS qualifies an undertaking that employs at least 250 persons, or has turnover in excess of £44 million and a balance sheet total in excess of £38 million (ESOS Regulations Sch 1 ¶¶1, 1A).
The schedule as first made in 2014 stated the money limbs in euros; the sterling figures have applied to qualification dates since the end of the Brexit transition period.
| Illustrative organisation | SECR (exceed two of £36m / £18m / 250) | ESOS (250+ staff, or both £44m and £38m) |
|---|---|---|
| 300 employees, £20m turnover, £10m balance sheet | Exceeds one condition — exempt | Qualifies on headcount alone |
| 90 employees, £40m turnover, £20m balance sheet | Exceeds two — in scope | Does not qualify: both money limbs must be exceeded |
| 250 employees exactly, £30m turnover, £15m balance sheet | Exceeds none — exempt | Qualifies: "at least 250" persons |
ESOS runs on a four-year phase with its own qualification date, where SECR runs on every financial year.
ESOS is regulated by the Environment Agency and its equivalents; SECR sits in a filed directors’ report and is picked up, if at all, through corporate reporting review.
An ESOS determination is not evidence of SECR scope in either direction, and neither is the absence of one.
The ESOS and SECR hub runs both regimes side by side, and the ESOS Phase 4 page covers the current phase’s dates; our sister reference site keeps a longer ESOS Phase 4 compliance guide, with its own SECR guide and SECR requirements page on uksrs.org.uk.
The Environment Agency’s own ESOS page sets out the ESOS qualification test in full.
Which year
The threshold is tested on the financial year, and so is everything else
SECR attaches to a financial year, not to a calendar year and not to an energy supplier’s billing year.
The disclosures belong in the directors’ report for the year in question, so the reporting period is the accounting period.
A changed accounting reference date produces a short or long period; it is still a financial year, and only the turnover figure is adjusted proportionately for the size test.
A subsidiary acquired part-way through the year is usually brought into a group report from the date it joins, in line with the accounts, and the size test then runs on the enlarged group’s aggregate figures.
A disposal does the reverse, and it is a common reason a company crosses back under the thresholds, which on the two-year rule still takes two years to take effect.
The conversion factors you apply follow the activity data, not the filing date; UK emissions factors explains which year’s set to use, and grid carbon intensity explains why the live grid figure is a different number.
Audit and assurance
Nothing here has to be audited, and the auditor reads it anyway
SECR disclosures do not require external verification or assurance: no paragraph in Part 7 or Part 7A mentions it.
The 2019 guidance says there is no statutory requirement to have environmental information audited.
The auditor is not silent, though: under section 496 of the Companies Act it states whether the directors’ report is consistent with the accounts and prepared in accordance with applicable legal requirements.
That is a consistency-and-legality opinion, not assurance over the emissions data.
An intensity ratio built on a turnover figure that does not match the accounts is exactly the kind of inconsistency that opinion is designed to catch.
The DESNZ review itself concedes that limited verification undermines confidence in data quality, and none of the five areas it lists for a future consultation is assurance.
What being in scope costs
Crossing the threshold has a measured price, and it was under-estimated
Until 2026 there was no public figure for what SECR compliance actually costs.
DESNZ’s evaluation and post-implementation review changed that.
Complying takes on average 94 hours of internal staff time a year, worth about £2,500.
56% of compliers also incur external costs, and once those are added the mean ongoing cost is £7,100 a year.
The 2018 impact assessment predicted about £2,300, a gap the evaluation partly attributes to a denominator error in the original costing.
Across the economy the review puts first-year costs at £270 million and £140 million a year afterwards, against £42 million and £26 million predicted.
Part of the gap is population: 76% more companies and LLPs were in scope than forecast.
These are averages from the review, not a quote for your organisation; this page gives no price for SECR support.
What being in scope obliges
What crossing the threshold makes you publish
The threshold decides two things at once: whether you report, and which of two disclosure sets you report.
| Disclosure | Quoted company (Part 7) | Large unquoted company or LLP (Part 7A) |
|---|---|---|
| Emissions | From combustion of fuel and operation of any facility; from purchased electricity, heat, steam or cooling — worldwide (¶15(2)–(3)) | From combustion of gas and consumption of fuel for transport; from purchased electricity (¶20D(1)–(2)) |
| Energy | Aggregate energy in kWh (¶15(3A)) | Aggregate energy in kWh (¶20D(3)) |
| UK share | Proportion relating to the UK and offshore area (¶15(3B)–(3C)) | May exclude energy and emissions outside the UK and offshore area (¶20D(5)) |
| Intensity ratio | At least one, emissions against a quantifiable factor (¶17) | At least one (¶20G) |
| Methodology | Methodologies used (¶16) | Methodologies used (¶20F) |
| Efficiency narrative | Principal energy-efficiency measures taken (¶15(3D)) | Principal measures taken, if any (¶20D(4)) |
| Comparatives | Prior year, after the first year (¶¶18, 18A) | Prior year, after the first year (¶20H) |
The Scope 3 point everyone gets backwards
For quoted companies SECR has no Scope 3 limb at all.
For large unquoted companies and LLPs one narrow Scope 3 item is mandatory: fuel for business travel in rental cars or employee-owned vehicles where the company is responsible for buying the fuel.
The statutory words are only “the consumption of fuel for the purposes of transport”; the rental-car formulation is the 2019 guidance’s gloss.
Everything else in Scope 3 is voluntary under SECR, which is one of the clearest gaps between SECR and UK SRS S2.
Emissions are calculated with the government’s conversion factors for company reporting, reissued each year; SECR carbon reporting works through the calculation and the SECR reporting template shows the disclosure laid out.
If you get it wrong
No SECR penalty regime, and the filing is public anyway
Schedule 7 creates no offence, fine or sanction of its own.
For companies, a defective report is caught by the ordinary directors’ report machinery: the offence of approving a report that does not comply, knowingly or recklessly (s.419(3)–(4)), and the court’s power to order a revised report (s.456).
For LLPs, regulation 12B creates SECR-specific analogues of those offences attached to the energy and carbon report.
The body authorised to apply to court is the FRC itself, since 6 May 2021 (SI 2021/465), and its corporate reporting review procedures record that all cases have been resolved without a court order.
The £150 to £7,500 scale often quoted on SECR pages is the Companies House penalty for filing accounts late (s.453), a different failure from filing on time with a deficient disclosure.
DESNZ’s evaluation puts suspected non-compliance at 14% to 23%, concentrated among private companies and LLPs, and the review calls enforcement light-touch.
Our read: the realistic risk is not a fine, it is a customer, investor or acquirer finding a required disclosure missing, most likely from a company that believed becoming medium-sized ended the duty.
| Accounts filed late by | Private company or LLP | Public company |
|---|---|---|
| Up to 1 month | £150 | £750 |
| 1 to 3 months | £375 | £1,500 |
| 3 to 6 months | £750 | £3,000 |
| More than 6 months | £1,500 | £7,500 |
What happens next
Is SECR 2026 the last version of it? Not on anything decided
The 2026 review recommends keeping SECR with amendments, and the Regulatory Policy Committee rated it fit for purpose on 15 May 2026.
Its possible directions are guidance on eligibility, sites and group boundaries, a standardised disclosure template, alignment with ISSB, CSRD and TCFD metrics, light-touch forward-looking elements and digital access.
The review says in terms that these “do not represent final decisions”.
The directors’ report is going; SECR is not going with it
Written Ministerial Statement HCWS973 of 21 October 2025 committed to removing the directors’ report, and said useful requirements, “including reporting on energy and emissions, will be retained and moved elsewhere in the Annual Report”.
The Modernising corporate reporting consultation of 7 September 2026 proposes exactly that at ¶149: the location of the SECR disclosures moves, and the duty does not.
Where UK SRS stands
UK SRS S1 and S2 were published by DBT on 25 February 2026 for voluntary use (DBT).
The FCA’s final rules (PS26/19, 30 September 2026) require listed companies in scope to report against UK SRS on a comply-or-explain basis for accounting periods beginning on or after 1 January 2027.
CP26/5, the consultation those rules finalise, estimated that around 600 listed companies would be affected, a small fraction of SECR’s 19,900.
Nobody has legislated to replace SECR with UK SRS; the UK SRS hub tracks that side, and TCFD reporting covers the regime UK SRS builds on.

Before you decide
Six questions on the SECR threshold
Most SECR scope errors come from one of six misreadings, and each has cost someone a year of reporting or a year of non-compliance.
Treating “£36m” as a threshold you reach rather than one you exceed.
Counting one large limb as enough.
Treating AIM as quoted.
Forgetting that a small quoted company reports at any size.
Moving in or out of scope on one year’s figures.
And applying the April 2025 Companies Act uplift to a regime that kept its own numbers.
The six questions beside this text test each one.

The vocabulary
The threshold terms, in plain English
| Term | What it means for SECR |
|---|---|
| Qualifying conditions | The three "not more than" limbs in ¶20B(2). Meeting two or more exempts a company; exceeding two or more puts it in scope. |
| Turnover | The year’s turnover, adjusted proportionately where the financial year is not twelve months long (¶20B(3)). |
| Balance sheet total | The aggregate of the amounts shown as assets in the balance sheet, before liabilities are deducted — not net assets. |
| Number of employees | The average number of persons employed under contracts of service, taken month by month. |
| Quoted company | A company whose equity is on the official list, officially listed in an EEA State, or admitted to dealing on NYSE or Nasdaq (CA 2006 s.385). Not AIM. |
| Net and gross group figures | Net is after intra-group eliminations, gross before them; a parent may use either, and the gross limits (£43.2m, £21.6m) are higher. |
| Low energy use | 40,000 kWh or less in the period (in the UK, for unquoted companies and LLPs). A relief from disclosure that must be stated, not an exemption from SECR. |
| Energy and carbon report | The LLP’s separate report, approved by the members and signed by a designated member. |
| Intensity ratio | At least one ratio of emissions to a quantifiable factor the company chooses. |
| Post-implementation review | DESNZ’s 2026 review of the SECR regulations, published 26 May 2026: retain with amendments, none yet decided. |
Frequently asked
SECR thresholds: questions people ask
What are the SECR reporting thresholds?
Quoted companies report under SECR at any size. An unquoted company or LLP is exempt for a financial year if it meets at least two of three conditions: turnover not more than £36 million, balance sheet total not more than £18 million, and not more than 250 employees (SI 2008/410 Schedule 7 paragraph 20B; SI 2008/1911 regulation 12B for LLPs). Turned round, you are in scope if you exceed at least two of the three, and a change of size only counts once it has lasted two consecutive financial years.
Did the April 2025 company size threshold changes affect SECR?
No. SI 2024/1303 raised the Companies Act size thresholds by about half for financial years beginning on or after 6 April 2025, so a company is now large for its accounts only above £54 million turnover and £27 million balance sheet total. SECR did not move, because Parts 7 and 7A of Schedule 7 carry their own threshold table and never cross-referred to the Companies Act size sections. The Explanatory Memorandum to SI 2024/1303 says the Regulations "do not affect" the SECR requirements. A company reclassified as medium-sized for its accounts can therefore still owe SECR disclosures.
Is £36 million turnover the SECR threshold, or is it more than £36 million?
More than. Paragraph 20B(2) lists the exemption conditions as "not more than £36 million", "not more than £18 million" and "not more than 250" employees, so a company exactly on a figure still meets that condition. DESNZ's 2026 post-implementation review writes the test as "£36 million or more", which is wider than the regulation at the boundary; where the two differ, the statutory instrument governs.
What is the SECR two-year rule?
Paragraph 20B(1) decides each year by looking at the preceding year too. After a company's first financial year, it is exempt if it meets the conditions in that year and the one before, or if it meets them in one of the two years and was exempt the year before. So one year over the thresholds does not bring an exempt company into scope, and one year back under them does not take an in-scope company out. In its first financial year a company is tested on that year alone.
Is there a low-energy exemption from SECR?
There is a relief from disclosure, not an exemption from SECR. An unquoted company or LLP that consumed 40,000 kWh of energy or less in the United Kingdom in the period, and a quoted company that consumed 40,000 kWh or less (with no UK limit), need not give the energy and emissions figures, but the report must state that the information is not disclosed for that reason. Silence is non-compliance. "Energy" means all forms of energy products, which is wider than the gas, electricity and transport fuel an unquoted company has to report.
Is an AIM-listed company a quoted company for SECR?
No. Section 385 of the Companies Act 2006 defines a quoted company as one whose equity share capital is on the official list, officially listed in an EEA State, or admitted to dealing on the New York Stock Exchange or Nasdaq. AIM is not the official list, so an AIM company is tested as an unquoted company on the £36m / £18m / 250 route and, if it is in scope, reports the unquoted disclosure set of UK energy use.
Does SECR apply to a UK subsidiary of an overseas parent?
Usually, in its own right. The subsidiary exemption in paragraph 20A(2) works only where the subsidiary is included in a group directors' report or group energy and carbon report that itself complies with Schedule 7, and a parent incorporated outside the UK prepares neither. So a UK subsidiary that exceeds two of the three thresholds, taking the two-year rule into account, reports for itself whatever its parent publishes elsewhere.
Do I leave SECR scope the year my turnover drops below £36 million?
Not on its own. Turnover is only one of three conditions, and you need to meet two of them. Even then, the paragraph 20B(1) machinery means an in-scope company is exempt again only once the conditions are met in two consecutive financial years.
Are LLPs in scope of SECR?
Large LLPs are, on the same £36m / £18m / 250 figures and the same two-year machinery, through regulation 12B of the LLP Regulations (SI 2008/1911) rather than through Schedule 7 paragraph 20B. An LLP has no directors' report, so its members prepare a separate energy and carbon report, approved by the members and signed on their behalf by a designated member.
How much does SECR compliance cost?
DESNZ measured it for the first time in its 2026 evaluation and post-implementation review. The mean ongoing cost is £7,100 a year per complier: about 94 hours of internal staff time, worth roughly £2,500, plus external costs that 56% of compliers incur. The 2018 impact assessment had predicted about £2,300. Across the economy, the review puts first-year costs at £270 million and £140 million a year afterwards.
What are the latest changes to SECR?
The regulations themselves have not changed since they came into force on 1 April 2019. DESNZ's 2026 post-implementation review recommends keeping SECR with amendments, which it says "do not represent final decisions"; the government's Modernising corporate reporting consultation (7 September 2026) proposes moving the SECR disclosures out of the directors' report without changing the duty; and DESNZ has said it intends to consult on SECR and ESOS later in 2026.
Which sectors are most affected by SECR?
SECR has no sector test. Scope turns on listing status and on size, so a bank and a manufacturer of the same size face the same duty. What differs by sector is the volume of the disclosure: an energy-intensive business has more gas, electricity and transport fuel to measure and more to say in its energy-efficiency narrative.
When are SECR reports due?
SECR has no deadline of its own. The energy and carbon report sits in the directors' report and is filed with the annual accounts: nine months after the year end for a private company or an LLP and six months for a public company, under section 442 of the Companies Act 2006. A 31 December 2026 year end at a private company therefore means filing by 30 September 2027.
Who has to report under SECR?
Every quoted company, at any size, under Schedule 7 Part 7 to SI 2008/410; unquoted companies, including AIM companies, that exceed at least two of £36m turnover, £18m balance sheet total and 250 employees; and LLPs on the same figures under SI 2008/1911. A subsidiary included in a parent's compliant group report need not report itself. Public bodies that are not companies are outside SECR.
Is there such a thing as SECR certification?
No. SECR creates a disclosure duty in the annual report, not a certificate, and no body is authorised to certify SECR compliance. The information is not audited, though the auditor reads the directors' report for consistency with the accounts. Some companies buy independent assurance over their figures voluntarily.
What are the exemptions from SECR reporting?
Two things take an organisation out of SECR: not exceeding two of the three size limits, for an unquoted company or LLP, and, for a subsidiary, having its figures in a compliant group report of its UK parent. Three reliefs then let an organisation in scope leave information out, each with a statement in the report: using 40,000 kWh or less in the year, disclosure that would be seriously prejudicial to its interests, and information that is not practical to obtain.
Is UK SRS replacing SECR?
No. The FCA's final rules in PS26/19 replace its TCFD-aligned listing rule for listed companies from 2027; they do not amend Schedule 7 to SI 2008/410. The government's 2026 post-implementation review recommended retaining SECR with amendments, and a consultation on streamlining energy and emissions reporting is planned but has not opened. A listed company in both regimes reports under both.
How is each SECR threshold measured?
Paragraph 20B(3) fixes it. Turnover is proportionately adjusted where the financial year is not twelve months long; the balance sheet total is the aggregate of the assets shown in the balance sheet, with no deduction for liabilities; and employees are the monthly average of persons employed under contracts of service, counted as people, not full-time equivalents.
Are there UK SRS thresholds like the SECR thresholds?
No size thresholds. The FCA's UK SRS rules reach listed companies by listing category, UKLR 6, 14, 15, 16 and 22, whatever their size, on a comply-or-explain basis from periods beginning on or after 1 January 2027. The FCA considered and rejected a size threshold. No threshold for private companies has been proposed, so an unlisted company over the SECR limits has no UK SRS duty.
Does a company at exactly 250 employees count as over the SECR threshold?
No. The qualifying conditions in paragraph 20B(2) of Schedule 7 are "not more than" 250 employees, £36m turnover and £18m balance sheet total. A company with exactly 250 employees satisfies that condition, so it has not exceeded it. To be in scope an unquoted company must exceed at least two of the three.
