UK SRS and the end of fragmented reporting

For years, UK companies have lived in a fragmented reporting maze. Emissions under SECR. Climate risks under TCFD. Stakeholder impact through GRI. Targets via SBTi. Investor metrics through SASB. Each framework is managed as a separate system with its own governance, metrics, and processes. The result: duplicated calculations, fragmented materiality assessments, and inefficient governance structures.

This fragmentation is no longer workable. The frameworks are now beginning to converge structurally and therefore, corporate governance systems need to keep pace.

Laying the foundations to tackle fragmentation

The UK has provided a 24-month lead-in period before the UK SRS becomes mandatory as a strategic window to build the right infrastructure.

Many will ask, ‘where do we start?’ and the answer is not what you would expect. First, you need to make a strategic choice about which framework should anchor your entire compliance architecture. This may sound odd at first; after all, SRS is the UK requirement, and you are a UK company. Why wouldn’t you start there?

Here’s the uncomfortable truth: most large UK companies already report against multiple frameworks. Many also operate across the EU and therefore must also comply with the Corporate Sustainability Reporting Directive (CSRD).

CSRD is fundamentally more comprehensive than SRS. It requires double materiality assessment (financial and impact materiality), mandatory third-party assurance from day one, detailed ESG metrics, EU Taxonomy reporting, and supply chain due diligence. This creates two compliance pathways:

• Pathway 1 (Inefficient): Start with SRS, then layer CSRD on top. Result: two distinct reporting workflows, duplicated materiality assessments, and independent governance committees.
• Pathway 2 (Strategic): Start with CSRD as your foundation, then supplement with SRS-specific elements. Result: one comprehensive reporting process generating CSRD-compliant disclosures, with SRS compliance as extracting and reformatting relevant CSRD data.

The strategic implication is clear: build to CSRD first, report to SRS second. You run one process and produce two outputs, not two processes producing two outputs.

Reporting what matters: One materiality assessment to serve all frameworks

Once you have made the strategic choice and selected the mandatory framework to anchor your compliance architecture, materiality will be your next challenge. Different frameworks define materiality differently. Most companies respond by attempting to conduct separate materiality assessments for each framework, defeating the purpose entirely.

The more effective model is a single, comprehensive materiality process addressing all perspectives simultaneously.

Roughly 48% of companies now use double materiality assessment (financial materiality and impact materiality). This unified approach allows you to:

• Understand the full range of material topics
• Organise disclosures strategically across frameworks
• Avoid duplicate assessment processes
• Recognise that topics material to investors increasingly align with topics material to communities and the environment

Companies building governance around comprehensive materiality are building governance that simultaneously manages financial risk, social impact, and environmental impact.

Data infrastructure and assurance: Build it once, build it right

Material topics must drive your data infrastructure. And increasingly, this data will need to be assured before publication.

Assurance over SRS is currently voluntary, but the FCA proposes that listed companies in scope of UK SRS will be required to disclose whether they have obtained third-party assurance. However, it is worth noting that under CSRD, limited assurance is a mandatory requirement, and under some voluntary frameworks, assurance is a requirement. Assurance is therefore rapidly becoming essential rather than optional.

Verifiers under ISAE 3000 and emerging ISSA 5000 must trace every material data point from source to final disclosure. Most companies’ current systems do not seamlessly meet these requirements. Below are three suggested ways to close the audit gap:

1. Complete audit trails: Centralised data systems maintaining records of who entered data, when it was validated, who approved it, and when it changed.
2. Standardised calculation methodologies: Same source data generating SRS, CSRD, and GRI metrics using framework-aligned methodologies.
3. Documented data governance processes: Clear documentation of who collects data, validation procedures, approval processes, and quality standards.

Companies that build assurance-ready infrastructure now will support efficient third-party assurance and position themselves ahead of emerging requirements. Those who delay will face audit challenges and significant rework.

The bigger picture: Integrated reporting as strategic governance

UK SRS is a signal that sustainability reporting is entering a phase of alignment and systemic integration. The trajectory of global regulation is clear: toward greater comprehensiveness. Companies that build integrated infrastructure now will adapt more easily to future requirements. Those that continue with fragmented compliance will struggle as frameworks evolve.

Under compliance-driven governance, a company calculates Scope 3 emissions and reports the number. Under strategic governance, it analyses where emissions concentrate, identifies reduction opportunities, engages suppliers, and tracks progress. The same data creates fundamentally different value.

The choice is no longer between compliance and non-compliance. It is between fragmented reporting systems that grow increasingly inefficient, and integrated systems that support long-term strategic governance.

How Bureau Veritas can help

Bureau Veritas provides end-to-end support across three core pillars:

• Foundational readiness: Gap assessments, double materiality assessments, climate scenario analysis, GHG accounting
• Disclosure development: S1 and S2 disclosures, governance and risk integration
• Independent assurance: Readiness assessments and third-party assurance over SRS disclosures

UK SRS is a catalyst. Companies that recognise this and act now will build integrated governance systems that manage multiple frameworks efficiently, reduce costs, and build stakeholder trust.

The time is now.
