Overview
The United Kingdom SDR, SRS and the FCA anti-greenwashing rule should be treated as one connected UK sustainability disclosure family. The FCA’s SDR regime governs sustainability claims, labels, naming, product disclosures and entity-level reporting, while the anti-greenwashing rule sets the baseline that all claims must be fair, clear and not misleading. SRS is a set of general sustainability disclosures.
This guide is for firms that need the UK framework as a standalone regional regime, not just as an add-on to EU or global reporting. It is especially relevant for asset managers, UK-authorised firms, and listed issuers preparing for the UK move away from TCFD-style reporting toward UK SRS/ISSB-aligned disclosure.
What UK SDR Is
SDR is the FCA’s Sustainability Disclosure Requirements regime for sustainable investment products and related marketing claims. It includes the anti-greenwashing rule, voluntary labels, naming and marketing rules, product-level disclosures, and entity-level disclosure expectations for larger asset managers.
In practice, SDR is the primary UK sustainable-finance disclosure regime, while SRS is the broader sustainability disclosure context firms often use when describing the regime and its supporting disclosures.
Why It Exists
The regime exists to raise trust, reduce misleading sustainability claims, and make UK sustainable investment products easier to compare. It solves the problem of vague or unsupported ESG marketing by requiring firms to substantiate claims and align labels, names and disclosures with actual product characteristics.
Companies use it because they must comply if they are in scope, and because it helps them avoid reputational and regulatory risk in a market where greenwashing enforcement is increasingly active.
Who Must Comply
The anti-greenwashing rule applies to all FCA-authorised firms making sustainability-related claims. The wider SDR regime applies to specific UK funds, asset managers and firms that use labels, ESG-related terms, or fall within the entity-level disclosure scope.
In the listed-issuer channel, the FCA is also consulting on moving UK listed companies from TCFD-aligned disclosures to UK Sustainability Reporting Standards, which creates a parallel corporate-reporting route.
Where It Is Used
SDR and the anti-greenwashing rule are used in the UK market across fund management, product marketing, investor communications and sustainability labelling. The listed-issuer reporting track is being redesigned by the FCA so that UK companies move from TCFD-style reporting toward UK SRS/ISSB-aligned disclosure.
Within a firm, the regime sits in compliance, legal, product governance, marketing review, reporting and risk oversight.
When It Applies
The anti-greenwashing rule took effect on 31 May 2024, the naming and marketing rules took effect on 2 December 2024, and the FCA continues to refine implementation guidance. Entity-level and product-level reporting deadlines depend on firm type, AUM size, product structure and whether the firm is using labels or ESG terms.
For listed companies, the proposed move to UK SRS is expected to phase in from 1 January 2027, subject to the final policy statement.
Unique Requirements
SDR brings together labels, naming rules, product-level disclosures and a mandatory anti-greenwashing baseline. The FCA also expects claims to be specific, supportable and consistent with the actual characteristics of the product or firm.
This makes the UK regime more conduct-focused than many broader sustainability standards.
How SDR, SRS And Anti-Greenwashing Link
Anti-greenwashing is the rule-set foundation, SDR is the disclosure and labelling regime that operationalises it, and SRS is the broader sustainability-disclosure context used by firms to organise claims, product information and reporting. Together they create a single UK framework for how sustainability claims are made, evidenced and disclosed.
In simple terms: the anti-greenwashing rule prevents unsupported claims, SDR structures the product disclosures, and the broader SRS context helps firms coordinate sustainability information consistently across their products and communications.
What To Pair With UK SDR
If you need global or topic-specific standards alongside UK SDR, the best pairings are ISSB for investor-grade reporting, TCFD for legacy climate disclosure, GRI for global impact reporting, SASB for sector-specific metrics, and TNFD where nature risk matters.
For a UK firm with a strong climate or product-risk story, ISSB and TCFD are the most natural additions; for a broader corporate sustainability program, GRI is the easiest global companion framework.
Data Retention And Archives
Your sustainability reporting records should be retained for multiple years to support continuity, evidence and audit readiness. GAIQ preserves published reports and supporting records as accessible archives, and prior UK reporting cycles can be carried forward or imported into later periods.
That helps firms maintain a defensible history of claims, disclosures and approvals as the UK regime continues to evolve.
How The GAIQ™ AI-Driven Platform Makes UK ESG Reporting Simpler
GAIQ™ preloads the relevant ESG Standards Frameworks based on your DMA results, so your team starts with the correct UK SDR or SRS scope already configured. It helps map product disclosures, track claim substantiation, and reduce duplicated work where UK disclosures need to align with global standards.
GAIQ™ also makes the active framework visible in the app header and D Data pages, so users always know which standards are selected, assigned, or both.
Next Steps For Your Team
Use UK SDR and the anti-greenwashing rule as your UK conduct baseline. If you also report internationally, pair it with ISSB, GRI or SASB depending on whether you need investor reporting, global impact reporting or sector-specific metrics.
Consider adding a global reporting framework to complement your UK SDR efforts, with ISSB or GRI being suitable options.
Adopt AI technology to automate data collection, mapping, and reporting workflows, which can significantly reduce the time and effort required for ESG reporting.

Executive Summary
UK SDR, SRS and the FCA anti-greenwashing rule form the UK’s current sustainability-claims and disclosure stack. The regime is conduct-led, enforcement-aware and increasingly connected to the UK’s move from TCFD to UK SRS.
For UK firms, the priority is not just disclosure quality, but claim quality.
