Get Started with UK SRS Reporting
Your comprehensive guide to implementing the new UK Sustainability Reporting Standards (UK SRS) - aligned with ISSB global standards
UK SRS Standards Now Published
The UK Sustainability Reporting Standards (UK SRS S1 and S2) have been officially published.
These ISSB-aligned standards represent the biggest shift in UK sustainability reporting since SECR was introduced.
Are You Affected by UK SRS?
🔵 Proposed To Be Required (FCA CP26/5)
Nobody is required to report under UK SRS today — this is the FCA's proposed scope, not a made rule.
- Commercial companies listing category (UKLR 6)
- Non-equity & non-voting equity shares category (UKLR 16), and the transition category (UKLR 22)
- Around 515 of the ~600 affected listed companies; the remaining 89 (secondary listing & depositary receipts categories) would face a lighter, home-regime disclosure instead
- AIM is not on the Official List and is not mentioned anywhere in CP26/5
🔄 Should Prepare Now
- Large UK companies meeting Companies Act thresholds
- PE-backed growth companies
- Public Interest Entities (PIEs)
- Export-oriented companies & supply chain leaders

Your UK SRS Journey: 5 Steps
Assess Applicability
Determine if your organization falls under UK SRS requirements based on:

- • Voluntary adoption benefits
Gap Analysis
Compare current reporting against UK SRS requirements:
- • Review SECR compliance
- • Map TCFD to UK SRS S2
- • Identify data gaps
- • Assess materiality processes
Data Infrastructure
Build robust data collection systems:
- • Scope 1, 2, 3 emissions
- • Climate scenario analysis
- • Transition planning metrics
- • Financed emissions (if applicable)
Governance Setup
Establish oversight and controls:
- • Board sustainability oversight
- • Management responsibilities
- • Internal controls framework
- • Assurance readiness
Prepare Disclosures
Create UK SRS-compliant reports:
- • General requirements (S1)
- • Climate disclosures (S2)
- • Connected information
- • Statement of compliance
UK SRS vs SECR: Key Differences
| Aspect | SECR (Current) | UK SRS (New) |
|---|---|---|
| Scope | Energy & carbon only | Comprehensive sustainability |
| Framework | UK Companies Act requirement | ISSB-aligned global standard |
| Climate Risk | Not required | Mandatory scenario analysis |
| Scope 3 | Not required | Required (including financed emissions) |

Frequently Asked Questions
When will UK SRS become mandatory?
The FCA's CP26/5 consultation (30 January 2026) proposes mandatory UK SRS S2 climate reporting for around 515 listed companies for accounting periods beginning on or after 1 January 2027, with a policy statement expected in autumn 2026.
Large private companies are expected to follow later.
Will UK SRS replace SECR?
Initially, both will coexist.
SECR remains statutory under the Companies Act while UK SRS will be implemented through FCA rules.
DESNZ's 2026 post-implementation review of SECR (26 May 2026) recommends retaining SECR requirements with amendments, not replacing them. The government has said it will consider how UK SRS energy and emissions data interacts with SECR to reduce duplication — a review of overlap, not a decision to merge or replace either regime, and no consultation on it has opened yet.
Do SMEs need to comply with UK SRS?
SMEs are not expected to be directly mandated initially.
However, supply chain pressure from larger companies reporting under UK SRS will likely require SMEs to provide sustainability data.
Voluntary adoption may also benefit SMEs seeking investment or contracts.
