SECR reporting template: the structure your report must follow

There is no official SECR form to fill in — but the Environmental Reporting Guidelines set out mandatory content that any format must cover.

This page breaks that content down into the sections a compliant Directors’ Report or Energy and Carbon Report actually needs, so a template built against it holds up to scrutiny.

Further down, a full illustrative worked example shows how those sections read once populated with figures.

The required sections

What a compliant SECR report contains

The Environmental Reporting Guidelines are the government’s definitive guidance on SECR content, and they specify what must appear in the Directors’ Report (companies) or the Energy and Carbon Report (LLPs), not a specific layout[1].

SECR report structure — mandatory elements
SectionContentApplies to
UK energy consumptionTotal kWh used to calculate emissions (electricity, gas, transport fuel)All qualifying entities
Scope 1 & 2 emissionsGreenhouse gas emissions in tCO2eAll qualifying entities
Global energy useWorldwide energy consumption, not just UKQuoted companies only

Energy efficiency narrativeAction taken during the year to improve energy efficiencyAll qualifying entities
Our read: the most common compliance gap isn’t missing data — it’s an inconsistent methodology statement or intensity ratio between years. A reviewer (or a future auditor under UK SRS) checks comparability first. If the ratio or the conversion factor source changes, say so explicitly and explain why.
Worked example

A full, illustrative SECR disclosure

Illustrative example only. “Thornfield Precision Ltd” is a fictional company invented for this walkthrough. It is not a real business, and every figure below is a constructed illustration, not data drawn from any actual filing. Use it to see how the mandatory sections in the table above translate into an actual Directors’ Report entry — not as a template to copy numbers from.

Thornfield Precision Ltd is an illustrative large unquoted UK manufacturer, meeting the SECR size test on turnover and employee count.

Its financial year runs to 31 March, so “FY2026” below means the year ended 31 March 2026, with FY2025 as the prior-year comparator required from a company’s second reporting year onward.

Scope 1 and Scope 2 emissions

Thornfield calculates its footprint on a financial-control consolidation boundary, applying a location-based method to purchased electricity and the year-appropriate DESNZ conversion factors to each activity-data stream[2], as required under the regulations that created SECR[4].

Illustrative

Thornfield reports tCO2e per £1m of revenue as its intensity ratio: 11.6 in FY2026 against 12.8 in FY2025.

Absolute emissions fell by roughly 3.3% year on year, and revenue grew, so the intensity ratio improved on both counts — this is the kind of consistent, same-methodology comparison the Environmental Reporting Guidelines are looking for from year two onward.

Methodology statement

“Emissions have been calculated using a financial-control consolidation approach, a location-based method for purchased electricity, and the 2026 UK Government GHG Conversion Factors for Company Reporting published by DESNZ[2] — the correct year-appropriate set for FY2026 activity, given the significant methodology change in this year’s electricity factor.

The reporting period is 1 April 2025 to 31 March 2026, aligned with the company’s statutory accounts.

There has been no change in methodology or intensity ratio from the prior year.”

Energy efficiency action taken during the year

During FY2026, Thornfield completed an LED lighting retrofit across its two manufacturing sites.

It installed sub-metering on compressed air systems to identify and fix leaks, replaced its two oldest diesel forklifts with electric equivalents, and fitted a voltage optimisation unit at its main site.

Four of its 22 company cars are now electric, up from one the previous year, as part of a phased fleet transition.

How this maps back: the energy table above satisfies the “UK energy consumption” row in the structure table; the emissions table and intensity-ratio figure satisfy the “Scope 1 & 2 emissions” and “intensity ratio” rows; the methodology statement and the energy efficiency narrative satisfy the last two rows. A real disclosure would present these in the Directors’ Report itself rather than as separate tables — the structure, not the layout, is what a reviewer checks.
Build your own

SECR report template structure — for your own spreadsheet

Illustrative structure, not a downloadable file. There is no official SECR spreadsheet or Excel template to download — government publishes required content, not a form[1]. The columns below are a structure to copy into your own spreadsheet; they are not populated with real data and should not be treated as a certified format.

Most organisations start their first SECR cycle in a spreadsheet before moving to dedicated carbon reporting software.

A simple sheet built around these columns covers the mandatory content in one place.

ColumnWhat goes in itMaps to

Scope (1/2/3)Which GHG Protocol scope the row falls underScope 1 & 2 emissions
Prior-year figureSame row, previous reporting yearPrior year comparatives
Intensity ratio inputsRevenue, FTEs or output units for the denominatorIntensity ratio

Once the sheet has more than a handful of sites or Scope 3 categories, the manual reconciliation this structure requires becomes the limiting factor — see the FAQ below on when to move to dedicated software.

Getting the numbers right

Conversion factors and where the data comes from

Activity data — kWh of electricity, litres of fuel, miles travelled — is converted into tCO2e using the official UK government conversion factors, published annually by DESNZ[2].

Using the year-appropriate factor set matters: the 2026 release changed the UK electricity methodology significantly, so a report using stale factors will not be comparable to peers using the current dataset.

Looking ahead

SECR data as the foundation for UK SRS

SECR’s Scope 1 and 2 figures are also the starting point for UK SRS S2 climate disclosures, which layer governance, strategy, scenario analysis and forward-looking targets on top of the same emissions data.

A SECR report built to a consistent, well-sourced structure now reduces the incremental work when broader UK SRS reporting becomes relevant.

Common questions

SECR reporting template: frequently asked questions

Is there an official SECR reporting template?

No. The government does not publish a fill-in-the-blanks template or mandate a specific format. Instead, the Environmental Reporting Guidelines set out the mandatory content a Directors’ Report (or Energy and Carbon Report for LLPs) must include. Any layout is acceptable provided it contains all the required elements — the structure on this page mirrors those requirements.

What must a SECR report include?

At minimum: UK energy consumption used to calculate emissions, Scope 1 and Scope 2 greenhouse gas emissions (in tCO2e), at least one intensity ratio, the methodology used for calculations, and prior-year comparison figures (from the second reporting year onwards). Quoted companies must also report global energy use and, where practical, Scope 3 emissions.

Do I need to report Scope 3 under SECR?

Only quoted companies are required to report Scope 3 emissions where practical to obtain, and the guidance gives latitude on which categories to include. Large unquoted companies and LLPs are not required to report Scope 3 under SECR, though many voluntarily disclose material categories to prepare for wider frameworks such as UK SRS.

What intensity ratio should I use?

The Environmental Reporting Guidelines require at least one intensity ratio but do not mandate which one — common choices are emissions per unit of revenue, per FTE employee, or per unit of physical output (for example, per tonne produced). The right ratio is the one that is meaningful for year-on-year comparison within your sector; changing it between reporting years without explanation undermines comparability.

Can I use a spreadsheet template for SECR reporting?

Yes, and many organisations do for their first few reporting years. A spreadsheet works well while data sources are simple. It becomes harder to maintain once multiple sites, business units or Scope 3 categories are added — at that point, dedicated carbon reporting software reduces manual error and produces a stronger audit trail.

Is there an example of a completed SECR disclosure?

We have built one below, using a fictional company, so you can see how the mandatory sections map onto an actual Directors’ Report entry. It is clearly labelled as illustrative — it is not drawn from a real company’s filing, and none of the figures should be copied into a real report. Its purpose is to show the shape a compliant disclosure takes, not to supply numbers.
