UK SRS: What it means for your business in 2026

On 25 February 2026, the UK Department for Business and Trade published the finalised UK Sustainability Reporting Standards (UK SRS). For sustainability managers across the UK, this isn’t a distant regulation to monitor. It’s the new reporting baseline, and the clock is already ticking on mandatory requirements.

Here’s what’s changed, what’s coming next, and what your organisation needs to do to get ahead of it.

What is the UK SRS?

The UK SRS are the UK government’s endorsed version of the ISSB’s global sustainability reporting standards – IFRS S1 (general sustainability disclosures) and IFRS S2 (climate-related disclosures) – with minor amendments for the UK context. UK SRS builds on and is expected to gradually replace TCFD-based disclosures, while existing regimes such as SECR remain in place..

UK SRS S1 covers all material sustainability-related risks and opportunities that could affect your organisation’s cash flows, access to finance, or cost of capital. UK SRS S2 focuses specifically on climate, including GHG emissions across Scopes 1, 2, and 3, scenario analysis, and transition plan disclosure.

What’s the difference from TCFD?

If your organisation already reports under TCFD, the good news is UK SRS builds on the same four pillars: Governance, Strategy, Risk Management, and Metrics and Targets. The transition isn’t a full rebuild.

But UK SRS goes significantly further in three key areas:

• Scope 3: The FCA has proposed value chain emissions to be explicitly required (comply- or- explain basis from 2027, becoming mandatory from 2028). The GHG Protocol remains the methodology standard for calculating these.
• Financial connectivity: Sustainability disclosures must be connected to and consistent with your financial statements, not siloed in a standalone ESG report.
• Quantified risk disclosure: Quantification of sustainability risks and opportunities linked to enterprise value is expected, not optional.

Think of it as TCFD with teeth, and a much closer relationship to your finance function.

When does it become mandatory?

The UK SRS are currently available for voluntary use. But mandatory requirements are already in motion on two tracks.

For listed companies: The FCA is proposing mandatory UK SRS S2 climate disclosures from 1 January 2027, with Scope 3 on a comply-or-explain basis from 2028, and broader S1 sustainability disclosures on a comply-or-explain basis from 2027, with up to a two-year transitional relief availa. The FCA consultation (CP26/5) closes 20 March 2026. There’s still time to respond and shape the final rules.

For private companies: The government’s Modernising Corporate Reporting (MCR) programme will consult later in 2026 on whether to extend UK SRS obligations to large private companies. Exact thresholds are yet to be confirmed, but if your organisation is of significant scale, it would be prudent to prepare now.

The time between now and mandatory isyour preparation window. Companies that use it well will have a significant advantage over those that scramble to comply under pressure.

What does UK SRS actually require you to report?

• Governance: How your board oversees sustainability and climate risk.
• Strategy: How climate and sustainability risks affect your business model, strategy, and financial planning.
• Risk Management: How you identify, assess, and manage sustainability-related risks.
• Metrics and Targets: Scope 1, 2, and material Scope 3 GHG emissions; climate targets; scenario analysis; transition plan status.

One key distinction from the EU’s CSRD: UK SRS uses financial materiality only, meaning you report what affects your enterprise value, not double materiality. This makes it more focused, but also more demanding in terms of linking sustainability data directly to financial outcomes.

What should you do right now?

Whether you’re a TCFD reporter looking to transition, or a private company anticipating the MCR programme, the preparation steps are the same:

1. Gap analysis: Map your current TCFD or SECR disclosures against UK SRS S1 and S2 requirements to identify gaps.
2. Data infrastructure: Ensure Scope 1 and 2 data is audit-ready and begin building Scope 3 data infrastructure now. DEFRA’s emission conversion factors are the UK standard for calculation.
3. Governance: Establish board-level sustainability oversight with clear accountability and documented escalation processes.
4. Financial connectivity: Integrate sustainability reporting with your financial statements and planning cycles, not as a separate exercise.
5. Dry run: Run an internal dry run against UK SRS S2 ahead of the FCA’s proposed 2027 application date.

How eco-shaper helps

eco-shaper is built for exactly this transition. Our carbon accounting and ESG reporting platform gives sustainability managers the structured data infrastructure to move from TCFD compliance to UK SRS readiness, ensuring auditability/assurance readiness without starting from scratch.

From Scope 1, 2, and 3 emissions tracking to governance documentation and audit-ready reporting, eco-shaper maps directly to the four UK SRS disclosure pillars. You get the data confidence to report voluntarily now, and the systems in place to meet mandatory requirements when they land.

But eco-shaper is more than a reporting tool. It’s a platform that actively helps your organisation identify value. By analysing your emissions data across Scopes 1, 2, and 3, eco-shaper surfaces cost reduction opportunities linked directly to emission reduction – from energy efficiency gains to procurement optimisation. It strengthens supplier engagement by giving you the structured data and workflows to collaborate with your value chain on emissions reduction, not just measure it. And it integrates seamlessly into your existing sustainability reporting process, connecting emissions data to financial planning and governance documentation in the way UK SRS S1 and S2 require. The result is a platform that doesn’t just help you comply – it helps you lead.
