UK SRS updates: the latest developments, dated
The UK SRS picture has moved fast through the first half of 2026 — final standards in February, the FCA consultation closing in March, and an assurance regime taking shape.
This page tracks each verified development, what it changed, and what is still expected, as of 16 June 2026.
The latest UK SRS developments at a glance
The UK SRS regime is being assembled by several bodies at once, so “what’s new” spans the standards themselves, the FCA’s listing rules, and a separate assurance workstream.
The table below records the developments we can verify against a primary source, most recent first.
| Date | Development | Source |
|---|---|---|
| 20 Mar 2026 | FCA CP26/5 consultation on mandatory UK SRS reporting for listed companies closed. | FCA CP26/5 |
| 25 Feb 2026 | DBT published the final UK SRS S1 & S2, available for voluntary use, with its consultation response. | GOV.UK / DBT |
| End Jan 2026 | Government published its response on an assurance oversight regime; FRC to run an interim register. | GOV.UK / DBT |
| 30 Jan 2026 | FCA published CP26/5, proposing UK SRS S2 reporting for in-scope listed companies from 1 January 2027. | FCA CP26/5 |

Final UK SRS S1 & S2 published
On 25 February 2026 the Department for Business and Trade published the final UK SRS S1 and S2, alongside its response to the June 2025 exposure-draft consultation[1].
The standards are UK-endorsed versions of the ISSB’s IFRS S1 and S2, with a small number of UK-specific amendments — including the removal of time-specific references to transitional reliefs[1].
They are now available for voluntary use; no entity is yet required to report against them[5].
For what the standards actually require, see our UK SRS requirements analysis and the endorsement breakdown.
FCA CP26/5 closed; Policy Statement expected autumn 2026
The FCA published Consultation Paper CP26/5 on 30 January 2026, proposing that in-scope listed companies report against UK SRS S2 for accounting periods beginning on or after 1 January 2027[2].
The consultation closed on 20 March 2026, and the FCA aims to publish a Policy Statement with final rules in autumn 2026, subject to the final UK SRS[2].
Until that Policy Statement is issued, the mandatory dates remain FCA proposals rather than law.
| Requirement | From | Basis |
|---|---|---|
| UK SRS S2 climate (excluding Scope 3) | FY beginning on/after 1 Jan 2027 | Mandatory |
| Scope 3 emissions | FY beginning on/after 1 Jan 2028 | Comply-or-explain (1-yr relief) |
| UK SRS S1 (non-climate) | FY beginning on/after 1 Jan 2029 | Comply-or-explain (2-yr relief) |

The assurance regime takes shape
The government published its response on an oversight regime for the assurance of sustainability-related financial disclosures at the end of January 2026[3].
It confirmed a voluntary, profession-agnostic regime overseen by the Financial Reporting Council, to be underpinned by legislation when parliamentary time allows; in the meantime the FRC has been tasked with establishing an interim register by mid-2026[3].
Supporting that work, the FRC published the voluntary UK sustainability assurance standard, ISSA (UK) 5000, on 12 November 2025, effective for periods beginning on or after 15 December 2026[4].
What is expected next
Two developments dominate the forward calendar for the rest of 2026.
FCA Policy Statement. The FCA aims to confirm its final Listing Rules and mandatory dates in autumn 2026, subject to the final UK SRS[2].
Private-company consultation. A government consultation on extending UK SRS to large, economically significant private companies and LLPs is expected during 2026 under the Modernising Corporate Reporting programme, though it had not been published as of June 2026[5].
We will record each development here as it is confirmed against a primary source.
