UK Corporate Reporting Reform: Streamlining Sustainability Disclosures Without Losing Substance
Key Takeaways
- The UK government has published a consultation on corporate reporting reform aimed at reducing duplication across sustainability disclosure requirements
- The proposals seek to consolidate overlapping obligations from SECR, TCFD listing rules, Companies Act s172, and Modern Slavery statements into a more coherent framework anchored around UK SRS
- While streamlining is welcome, there is a risk that non-climate ESG metrics — particularly social and governance disclosures — are lost in a climate-centric consolidation
- The FCA’s existing TCFD listing rules will be superseded by UK SRS requirements, but the transition timeline needs careful management
- SMEs in large company supply chains face indirect disclosure pressure, and the reform should clarify proportionate expectations for smaller businesses
The Problem: Overlapping Requirements
UK companies currently face multiple overlapping sustainability disclosure requirements, each with its own scope, format, and enforcement regime:
- SECR (Streamlined Energy and Carbon Reporting): Mandatory for large companies and LLPs since April 2019. Requires disclosure of UK energy use, associated GHG emissions, and an intensity metric in the directors’ report
- TCFD-aligned disclosure: Required by FCA listing rules for premium-listed companies (since 2021) and standard-listed companies (since 2022). Also required by the Companies (Strategic Report) (Climate-related Financial Disclosure) Regulations 2022 for large PIEs and AIM companies
- Companies Act s172 statement: Requires directors to describe how they have had regard to various stakeholder interests, including environmental impact
- Modern Slavery Act s54: Requires qualifying organisations to publish annual statements on steps taken to prevent modern slavery in operations and supply chains
- UK SRS (incoming): ISSB-based sustainability reporting standards that will become the primary mandatory climate disclosure framework
The result is duplication, confusion, and wasted effort. A FTSE 250 company may report essentially the same greenhouse gas data in three different formats across three different documents, each reviewed by different teams and audited under different standards.
What the Reform Proposes
The spring 2026 consultation sets out a framework for consolidation:
1. UK SRS as the Primary Framework
UK SRS will become the single mandatory climate disclosure standard, replacing the climate-related elements of SECR and TCFD listing rules. Companies in scope of UK SRS will no longer need to produce separate TCFD reports or SECR climate disclosures.
2. SECR Retained for Energy Data
The energy-specific elements of SECR (total energy consumption, energy efficiency actions) may be retained as a standalone requirement, potentially integrated into UK SRS as an additional disclosure topic. This recognises that energy data serves purposes beyond climate reporting, including ESOS compliance and energy management.
3. s172 Statement Simplified
The s172 statement requirement is proposed for simplification, with environmental considerations absorbed into UK SRS disclosures and other stakeholder considerations streamlined to reduce boilerplate language.
4. Modern Slavery Act Unchanged
The Modern Slavery Act reporting requirement sits in a separate policy domain and is not proposed for consolidation into UK SRS. However, the consultation asks whether a cross-reference mechanism could reduce duplication for companies that discuss supply chain human rights in both their modern slavery statement and their strategic report.
The Risk: Losing Non-Climate ESG Metrics
UK SRS, based on ISSB standards, is primarily focused on climate and sustainability-related financial risks. It does not comprehensively cover:
- Social metrics: Workforce diversity, pay ratios, employee wellbeing, community impact
- Governance beyond climate: Board diversity, executive remuneration structure, tax transparency
- Biodiversity and nature: While ISSB is developing a nature standard, it is not yet available
- Circular economy: Waste reduction, material efficiency, product lifecycle
If reporting reform strips away existing disclosure mechanisms without replacing them, companies may reduce their social and governance reporting. This would be a step backwards at a time when investors increasingly demand comprehensive ESG data.
The consultation should be read carefully for signals about whether the government intends to develop UK SRS equivalents for social and nature topics, or whether these will remain in voluntary frameworks like GRI or ESRS.
Comparison with the EU Approach
The EU faced a similar challenge with CSRD and has taken a different approach. Under the Omnibus I simplification (published February 2026), the EU has:
- Reduced the number of mandatory ESRS datapoints by approximately 70% for companies below certain thresholds
- Introduced a voluntary simplified standard (VSME) for SMEs
- Delayed the phase-in for certain company categories
The UK approach is structurally different: rather than simplifying a comprehensive standard, it is building from a narrower base (ISSB/climate-first) and asking whether additional topics should be added. The risk is that the UK ends up with less comprehensive mandatory disclosure than the EU, potentially creating challenges for UK companies with EU operations that need to comply with both regimes.
Implications for SMEs
While UK SRS is initially targeted at listed companies and large entities, the reform has significant implications for SMEs:
- Large customers subject to UK SRS (and particularly Scope 3 requirements) will request climate data from their SME suppliers
- The reform should clarify what data large companies can reasonably request from SMEs, potentially endorsing a standardised SME data template
- Proportionality is essential: SMEs should not face the same reporting burden as FTSE 100 companies, but they need clear guidance on what “good enough” looks like
What Companies Should Do Now
- Respond to the consultation: The reform will shape UK sustainability reporting for the next decade. Companies should engage, particularly on the treatment of non-climate metrics
- Map your current reporting: Identify where you currently report the same data in multiple formats. This is the duplication that reform should eliminate
- Preserve voluntary disclosures: If you currently report social or governance metrics beyond the minimum, do not stop simply because a regulatory consolidation removes the mandate. Investor expectations often exceed regulatory minimums
- Prepare for UK SRS: Regardless of reform outcomes, UK SRS is coming. Building your climate data systems now ensures you are ready for the consolidated framework
- Assess supply chain impact: If you are a large company, consider how reform affects the data you request from suppliers. If you are an SME, understand what your customers will need from you under the new regime
