ESG reporting — UK guide and cluster hub
ESG reporting in the UK isn’t one report — it’s a set of overlapping regimes converging on UK SRS as the backbone. Three layers: corporate disclosure (UK SRS, SECR, TCFD), fund-product disclosure (FCA SDR), and the regulated ESG ratings market from 29 June 2028.
Overlapping Regimes Converging on UK SRS
ESG reporting means disclosing a company's environmental, social and governance information so investors and stakeholders can assess it.
In the UK there is no single 'ESG report' — instead, several overlapping regimes are converging on one investor-focused backbone: the UK Sustainability Reporting Standards (UK SRS).
This guide maps the UK's ESG reporting landscape and shows where each piece fits.
What ESG reporting actually is
An umbrella term covering environmental, social and governance disclosure — voluntary globally, but increasingly mandatory for large UK companies through SECR, TCFD-aligned rules and emerging UK SRS.
What ESG reporting actually is
"ESG reporting" is an umbrella term covering how a company discloses its environmental impact and risks (emissions, energy, nature), its social performance (workforce, health and safety, supply chain), and its governance (board oversight, controls, ethics) 46. Globally, much of it has been voluntary — driven by frameworks such as the Global Reporting Initiative (GRI), CDP and the Science Based Targets initiative — but in major economies it is increasingly mandatory for large companies 4632. The UK is firmly in that shift: ESG reporting is moving from principles and voluntary practice to structured, regulated requirements 46.
Is ESG reporting mandatory in the UK?
For large companies, much of it already is. SECR, TCFD-aligned Listing Rules, SI 2022/31 and emerging UK SRS S2 create mandatory ESG obligations for ~13,500 UK entities today, with more from 2027.
Is ESG reporting mandatory in the UK?
For large companies, much of it already is. TCFD-aligned climate disclosure is mandatory for many large and listed UK companies, and SECR has required energy and carbon disclosure since 2019 4610. The trajectory is toward more: the FCA's CP26/5 proposes mandatory UK SRS S2 climate reporting for listed companies from 2027, with Scope 3 and wider sustainability on a comply-or-explain basis 6. Smaller companies are not generally caught yet, but increasingly receive ESG data requests from larger customers and investors in their value chain 46.
Why UK SRS is becoming the centre of gravity
UK SRS S1 and S2 consolidate the climate reporting that TCFD pioneered, extend it to full Scope 3 and broader sustainability topics, and tie disclosures explicitly to the financial statements under financial materiality.
Where UK SRS fits — and why it’s the centre of gravity
UK SRS is becoming the backbone of UK corporate ESG disclosure 1. It consolidates the climate reporting that TCFD pioneered, extends it to full value-chain emissions and wider sustainability, and ties sustainability disclosures explicitly to the financial statements 124. Crucially, it applies financial (enterprise-value) materiality — reporting how ESG factors affect the company — rather than the EU's double materiality, which also captures the company's impact on the world 929. For most UK companies building an ESG reporting capability, UK SRS is the standard to organise around 1.
What to do next
Treat UK SRS as the spine, build a single ESG data set you can map across frameworks, and watch the expanding regulatory perimeter through 2028.
What to do
Treat UK SRS as the organising spine of your ESG reporting, build a single ESG data set you can map across frameworks, and watch the expanding perimeter — fund-level SDR rules, the new ESG ratings regime, and the Government's plans to extend corporate reporting to large private companies 4647. *(Practitioner how-to and tooling: see srsreport.co.uk.)*
ESG reporting — frequently asked
What ESG reporting covers, mandatory status, UK SRS positioning, and how the regimes interoperate.
What is ESG reporting?
ESG reporting means disclosing a company's environmental, social and governance information so investors and stakeholders can assess it.
In the UK, there's no single "ESG report" — instead, several overlapping regimes are converging on UK SRS as the investor-focused backbone.
Is ESG reporting mandatory in the UK?
For large companies, much of it already is.
TCFD-aligned climate disclosure and SECR energy reporting are mandatory for many large and listed UK companies.
The FCA proposes mandatory UK SRS S2 climate reporting for listed companies from 2027, with wider sustainability on comply-or-explain.
What frameworks apply in the UK?
UK companies encounter several ESG frameworks: UK SRS (ISSB-aligned) as the emerging mandatory baseline, SECR for energy and carbon, GRI for voluntary impact reporting, CDP and SBTi for climate disclosure and targets, plus ESRS for EU operations.
The task is interoperability across frameworks.
How does ESG reporting relate to UK SRS?
UK SRS is becoming the backbone of UK corporate ESG disclosure.
It consolidates TCFD climate reporting, extends it to full value-chain emissions and wider sustainability, and ties sustainability disclosures explicitly to financial statements using financial materiality.
What is the FCA SDR / anti-greenwashing rule?
The FCA's Sustainability Disclosure Requirements (SDR) regime governs how investment products are labelled and described, backed by an anti-greenwashing rule that applies to all FCA-authorised firms.
This is the fund and product-level layer of UK ESG regulation.
Is the UK regulating ESG ratings?
Yes, for the first time.
The Financial Services and Markets Act 2000 (Regulated Activities) (ESG Ratings) Order 2025 was signed into law on 15 December 2025.
In-scope ESG ratings providers must obtain FCA authorisation by 29 June 2028.
