How UK SRS Differs from IFRS S1/S2
UK Sustainability Reporting Standards (UK SRS) are substantially aligned with IFRS S1 and IFRS S2.
The UK government consulted on six amendments to the IFRS baseline in June 2025 to address UK-specific legislative and regulatory requirements, but the final Standards differences from IFRS are set out in 4Annex A of the government consultation response, which carries no count.
These differences adapt rather than replace the international baseline, preserving global comparability while meeting domestic legal obligations.
For the international standards themselves, see our IFRS S1 and S2 overview and the dedicated IFRS S2 guide.
The areas covered on this page include 4connected information under the Companies Act 2006, 1scenario analysis disclosure, and 1governance requirements.
Additional areas include 7NFSIS integration obligations, UK-specific materiality considerations, and transition plan timing coordination.
Each area reflects a difference between IFRS requirements and existing UK corporate reporting law.
| Amendment Area | IFRS S1/S2 Baseline | UK SRS Enhancement | Legal Basis |
|---|---|---|---|
| Connected Information | Connected information encouraged but not required | Must explain connection to annual financial statements | Companies Act 2006 s.414CB(2A) |
| Scenario Analysis | Climate scenario analysis when used in strategy assessment | Mandatory disclosure of climate scenarios and assumptions (paragraph 22) | UK SRS S2 paragraph 22 enhancement |
| Governance Oversight | Board or management oversight disclosure | Specific board-level climate competency and training disclosure | UK SRS S2 paragraph 6 enhancement |
| Materiality Assessment | Entity-specific materiality process | Consideration of UK Green Taxonomy alignment where relevant | NFSIS regulation cross-reference |
| NFSIS Integration | No specific integration requirements | Cross-referencing with NFSIS under section 414CB(2A) | Companies Act 2006 s.414CB(2A) |
| Transition Plan Timing | Transition plan disclosure where entity has one | Disclosure timing aligned with separate Government consultation | Separate mandatory transition plan framework |
Connected Information
UK SRS S1's Connected Information section requires entities to 5explain how climate-related risks and opportunities connect to information disclosed in annual financial statements.
IFRS S2 3encourages such connections but does not mandate them.
Where an entity reports under UK SRS, this connected-information requirement operates alongside 1Companies Act 2006 section 414CB(2A), which requires strategic reports to be consistent with financial statements.
In practice, this means disclosing how 1climate-related impairments, provisions, contingent liabilities, and going concern assessments in financial statements relate to sustainability risks and opportunities described in UK SRS disclosures.
Companies must 4identify specific financial statement line items affected by climate factors and explain the connection methodology.
Mandatory Scenario Analysis
UK SRS 1paragraph 22 makes climate scenario analysis disclosure mandatory, beyond IFRS S2's conditional requirements.
While IFRS S2 3requires scenario analysis disclosure only when scenarios inform strategy assessment, UK SRS requires disclosure of climate scenarios used and their key assumptions regardless of strategic application.
This enhancement addresses 4FCA concerns about climate scenario consistency across UK-listed companies.
Entities must disclose 1specific scenarios used, underlying assumptions about climate pathways, timeframes considered, and how scenarios relate to business model resilience.
The requirement applies whether scenarios are developed internally, sourced externally, or adapted from frameworks like 11NGFS or IEA pathways.
Board-Level Governance Enhancements
UK SRS enhances IFRS S1 governance requirements with 1specific disclosure obligations about board-level climate competency and training.
While IFRS S1 2requires general oversight disclosure, UK SRS paragraph 6 requires entities to describe how board members maintain climate-related competency and any specific training undertaken.
This amendment responds to 4regulatory expectations about board capability in climate risk oversight.
Disclosures must cover 1board composition relating to climate expertise, training programs for directors, external advisory arrangements, and how climate competency informs board decision-making processes.
The requirement applies to both executive and non-executive directors.
UK-Specific Materiality Assessment
UK SRS preserves the 3IFRS approach to entity-specific materiality while requiring consideration of 9UK Green Taxonomy alignment where relevant.
This amendment does not make Green Taxonomy disclosure mandatory but requires entities to 1explain whether and how UK taxonomy criteria inform materiality assessments.
The enhancement addresses 11Government policy coordination between sustainability reporting and green finance frameworks.
Entities with activities covered by UK Green Taxonomy technical screening criteria must 1disclose whether taxonomy alignment influences materiality determination for climate-related risks and opportunities.
Non-covered entities may exclude this consideration.
NFSIS Cross-Referencing Requirements
UK SRS requires 5cross-referencing with Non-Financial and Sustainability Information Statement (NFSIS) disclosures under Companies Act 2006 section 414CB(2A).
This amendment prevents 7duplication between UK SRS and NFSIS requirements while ensuring legal compliance with both frameworks.
In practice, entities must 1identify where NFSIS disclosures satisfy UK SRS requirements and provide clear cross-references.
Where information differs between frameworks, entities must 7explain the difference and ensure both requirements are met.
This coordination mechanism maintains reporting efficiency while meeting distinct legal obligations.
- Clear cross-references between UK SRS and NFSIS content
- Explanation of any differences in approach or emphasis
- Demonstration that both frameworks' requirements are satisfied
Implementation Timeline Coordination
Transition plan disclosure timing under UK SRS is coordinated with 11a separate Government consultation on mandatory transition plan production.
While IFRS S2 3requires transition plan disclosure where entities have developed plans, UK SRS aligns disclosure timing with the separate transition plan framework under development.
This coordination prevents 4premature disclosure obligations before transition plan production requirements are finalised.
Entities must 1disclose whether they have developed transition plans and, if so, provide IFRS S2-compliant information.
Where mandatory transition plan requirements apply from future dates, UK SRS disclosure timing aligns accordingly.
Are UK SRS completely different from IFRS S1/S2?
No. UK SRS is substantially aligned with IFRS S1/S2.
The UK government consulted on six amendments to the IFRS baseline in June 2025 to address UK-specific legislative and regulatory requirements; the final Standards differences from IFRS are set out in Annex A of the government consultation response, which carries no count.
What is UK SRS Connected Information, and how does it relate to financial statements?
UK SRS S1 Connected Information means explaining how climate-related risks and opportunities connect to information in the annual financial statements.
Where an entity reports under UK SRS, this operates alongside the Companies Act 2006 requirement that strategic reports be consistent with financial statements (section 414CB(2A)).
UK SRS itself is currently voluntary - no entity is required to report under it as at 20 Aug 2026.
How does the UK scenario analysis requirement differ from IFRS S2?
IFRS S2 requires scenario analysis disclosure only when scenarios are used in strategy assessment.
UK SRS paragraph 22 makes climate scenario disclosure mandatory, including the scenarios used and key assumptions, regardless of whether they inform strategy.
What is NFSIS and how does it relate to UK SRS?
The Non-Financial and Sustainability Information Statement (NFSIS) is a Companies Act 2006 construct — section 414CB, whose heading was amended to "non-financial and sustainability information statement" by SI 2022/31.
It is not UK implementation of the EU Corporate Sustainability Reporting Directive.
A company reporting under UK SRS specifies that framework in the NFSIS under Companies Act section 414CB(6) instead of repeating the information.
Do the UK amendments apply to all companies reporting under UK SRS?
UK SRS is currently voluntary - no entity is required to report under it as at 20 Aug 2026.
Under the FCA proposed rules (CP26/5), UK SRS reporting is proposed for listed companies in the UKLR 6, 16 and 22 categories only; companies in the UKLR 14 and 15 categories would instead make a signposting statement about the overseas or voluntary standards they follow, not report under UK SRS.
Will UK SRS remain aligned with future IFRS updates?
The Government has committed to maintaining substantial alignment with IFRS sustainability standards.
Future IFRS updates will be assessed for adoption, with UK amendments preserved where they address specific UK legislative requirements.
How do UK amendments affect international comparability?
The differences between UK SRS and IFRS, set out in Annex A of the government consultation response, are designed to enhance rather than replace IFRS requirements.
International readers will find familiar IFRS structure with additional UK-specific disclosures clearly identified in separate paragraphs or sections.
