UK SDR disclosure is the set of rules from the Financial Conduct Authority (FCA) that governs how asset managers describe sustainable investment products and how they report on their own climate approach. The regime was finalized in policy statement PS23/16. It has four parts: an anti-greenwashing rule for every authorized firm, naming and marketing rules, tiered disclosures at product and entity level, and voluntary investment labels. This guide explains who must do what, where firms most often go wrong, and how to build the competence to sign off sustainability claims.
TL;DR
- The anti-greenwashing rule (ESG 4.3.1R) has applied to all FCA-authorized firms since 31 May 2024, whatever their size or product range.
- Labels are voluntary. Naming and marketing rules and disclosures are not: using terms such as "sustainable" or "impact" in a product name or marketing pulls a product into the regime.
- Entity-level reporting, aligned to the four TCFD pillars, started on 2 December 2025 for firms with AUM over £50 billion. Other managers above £5 billion must report from December 2026.
- The regime currently covers UK-domiciled funds. Overseas funds are outside it, but distributors must tell investors so.

What UK SDR disclosure covers
The FCA describes the regime as a package for sustainable investment products: mandatory rules on naming and marketing and on disclosures, plus voluntary labels. The rules sit in the FCA's ESG Sourcebook. The aim is to protect consumers from greenwashing and give them a clear way to compare sustainable products.
It helps to think in four layers:
| Layer | Who it applies to | Mandatory? |
|---|---|---|
| Anti-greenwashing rule | All FCA-authorized firms | Yes, since 31 May 2024 |
| Naming and marketing rules | Asset managers using sustainability terms in product names or marketing | Yes |
| Product and entity-level disclosures | Asset managers, in tiers by AUM and product type | Yes |
| Investment labels | Asset managers that choose to label a product | No, voluntary |
Most confusion comes from treating these as one obligation. They are four, with different triggers and different timelines.
The anti-greenwashing rule applies to every authorized firm
The anti-greenwashing rule took effect on 31 May 2024. It requires any sustainability-related claim about a product or service to be fair, clear, not misleading and consistent with the actual sustainability characteristics of the offering. It covers financial promotions and other communications to UK clients, and the FCA's guidance (FG24/3) extends to visual content and firm-level statements.
Two points catch firms out:
- It is not limited to sustainable funds. A wealth manager, adviser or insurer with no labelled products is still caught if it makes a sustainability claim in a brochure, a website banner or a pitch deck.
- It is not limited to text. Icons, imagery and colors that imply environmental credentials count as communications.
A practical test is to trace every sustainability claim back to evidence you hold today. If the claim says "net zero aligned", can you show the methodology, the data and the owner? If the evidence is a plan, the claim should say plan. Smaller firms without a dedicated compliance team may find this plain-language overview of why compliance matters for smaller businesses a useful reminder of how to make controls proportionate and repeatable.

Naming and marketing: where the regime bites
Labels get the attention, but the FCA's own framing shows the real force lies elsewhere. Labels are voluntary. Asset managers must meet the naming and marketing requirements for retail investment products that use sustainability-related terms in their names or marketing (ESG 4.3.2R to ESG 4.3.10R).
The consequence is a high cost of entry for marketing sustainability. If a fund is called "sustainable" or "impact", the manager has to hold rigorous, documented evidence that the product does what the name implies, and make the required disclosures. A manager that does not want that burden has two honest options: drop the terms, or build the evidence base.
The FCA has also offered temporary flexibility on how firms comply with the naming and marketing rules in certain circumstances. Check the current statement and the date on it before relying on it, because transitional measures change.
Disclosures: product level and entity level
Product-level disclosures
Product-level disclosures are required for labelled products and also for unlabelled products that use sustainability-related terms in their naming or marketing. That second group is the one firms underestimate. An unlabelled fund with a "responsible" tagline still has paperwork to produce.
Entity-level disclosures
Entity-level requirements are codified in ESG 5.6 and ask firms to disclose how they take climate-related risks and opportunities into account. According to Linklaters' quick guide, they must follow the TCFD four-pillar structure: governance, strategy, risk management, and metrics and targets. The timetable is tiered:
| AUM | Entity-level reporting starts |
|---|---|
| Over £50 billion | 2 December 2025 |
| Over £5 billion (all other managers) | December 2026 |
If you manage between £5 billion and £50 billion, your first report is close. Today is mid-October 2026, so the practical work (data, governance sign-off, drafting) should already be well under way.
The rules sit in the same Sourcebook as the earlier climate-related disclosure rules for asset managers, life insurers and pension providers set out in PS21/24, so firms already reporting under that framework have a head start on structure.
The consistency problem
The most common failure point is a gap between entity-level disclosures and product-level claims, and the FCA's supervisory attention follows it. If your entity report says climate governance is still maturing while a fund factsheet promises active stewardship on transition, a reviewer will see the mismatch. Firms that do this well signpost across the layers so a reader can move from a marketing claim to a product disclosure to the firm-wide report and find the same story.
Do the rules apply to overseas funds?
Not at present. The regime is limited to UK-domiciled funds. Overseas funds, including UCITS, do not need a UK label or the associated SDR disclosures. Distributors must, however, prominently notify investors that these products are not subject to the UK SDR and labelling regime.
Do not read this as permanent. The FCA has indicated an ambition to widen scope to portfolio management services, pension products and overseas funds over time. Firms that build good evidence practices now will not have to rebuild later.
UK SDR is not a bridge to SFDR
The SDR is designed to be interoperable with global standards such as TCFD and ISSB, but it remains a distinct labelling regime. Commentary on the rules, including William Fry's analysis, points to a different philosophy from the EU's transparency-led approach: the UK framework prioritizes retail investor protection through categories and claims discipline.
For a manager operating in both markets, that means separate mapping exercises. Data you collect for EU reporting, such as principal adverse impacts, will inform UK disclosures, but it will not satisfy them automatically. Our guide to making principal adverse impacts audit-ready covers the EU side. For the climate reporting lineage behind entity-level disclosure, read TCFD to ISSB: what changes for climate reporting.
A readiness checklist for compliance and sustainability leads
- Inventory every sustainability claim. Websites, factsheets, pitch decks, RFP answers, social posts, fund names.
- Classify each product. Labelled, unlabelled but using sustainability terms, or neither.
- Attach evidence to each claim. A named owner, a data source and a date.
- Draft entity-level disclosures on the four TCFD pillars. Start with governance, since it forces decisions about who owns climate risk.
- Reconcile entity and product disclosures. One narrative, cross-referenced.
- Review distributor communications. If you distribute overseas funds, confirm the required notice is prominent.
- Set a review cycle. Rules, guidance and transitional measures change, so schedule checks against the FCA's own pages.
Our perspective
We train professionals who have to defend a sustainability claim to a regulator, an auditor or a board, and the pattern is consistent. The firms that struggle with SDR rarely lack ambition. They lack a shared method for turning a marketing sentence into an evidenced statement.
Three convictions shape how we teach this. First, competence has to be cross-functional: the person who writes the factsheet, the person who owns the data and the person who signs off the entity report must work to the same standard. Second, credentials should test judgment, not attendance, which is why our assessments are built around real pass thresholds. Third, the regime will widen. Building skills in TCFD-aligned reporting, ISSB standards and assurance now is cheaper than retrofitting after scope expands.
SDR rewards firms that treat disclosure as evidence management, not copywriting.

FAQ
Is the SDR label mandatory?
No. Labels are voluntary, and a manager can invest sustainably without one. What is mandatory is the naming and marketing regime and the disclosures that follow if you use sustainability-related terms. Many firms discover they are in scope through their product names, not through a decision to label.
Does the anti-greenwashing rule only affect asset managers?
No. It applies to all FCA-authorized firms, regardless of AUM or whether they offer sustainability-focused products. Any sustainability-related communication about a product or service in the UK must be fair, clear and not misleading. Firms should follow the FCA's finalized guidance, FG24/3.
When must my firm publish entity-level disclosures?
Managers with AUM over £50 billion were required to report from 2 December 2025. Other managers with AUM above £5 billion report from December 2026. The disclosures follow the four TCFD pillars: governance, strategy, risk management, and metrics and targets.
Do UK SDR rules apply to overseas funds sold in the UK?
Not currently. Overseas funds, including UCITS, do not need a label or SDR disclosures. Distributors must still prominently tell investors the product is outside the UK regime. The FCA has signaled it may extend scope later.
