UK SDR Sustainability Labels Explained: A Guide for Investors

The UK's Sustainability Disclosure Requirements (SDR), introduced by the Financial Conduct Authority (FCA), represent the most significant overhaul of sustainable investment labelling in British regulatory history. For investors who care about where their money goes — and for those who simply want to avoid buying something mis-sold as "green" — understanding the SDR framework is now essential. This guide explains how the regime works, what each label means in practice, and what questions to ask before investing.

Why the SDR Was Needed

Over the past decade, "ESG", "sustainable", "responsible", and "green" became ubiquitous marketing terms in the UK fund industry. The problem was that no consistent definition underpinned these claims. Two funds calling themselves "sustainable" might use entirely different approaches: one might exclude tobacco; another might actively hold fossil fuel companies and argue that engagement makes it sustainable. Investors had no reliable way to compare or verify claims.

The FCA's SDR regime — which came into full force for authorised fund managers in 2024, with the anti-greenwashing rule applying from May 2024 and the naming and marketing rules from December 2024 — is designed to change that. It applies to UK-authorised investment funds, including UCITS and UK AIFs. It does not yet apply to portfolio management services or overseas funds, though the FCA has signalled extensions.

Important note: The SDR is a regulatory regime, not a quality endorsement. A labelled fund is not necessarily a better investment; it is simply one that has met specified criteria. Regulatory classification does not remove investment risk. The value of investments can fall as well as rise.

The Anti-Greenwashing Rule

Before examining the labels themselves, it is worth understanding the anti-greenwashing rule, which applies to all FCA-authorised firms — not just those seeking a label. The rule requires that any sustainability-related claims made about financial products or services must be:

• Fair — accurately representing the product's actual sustainability characteristics
• Clear — understandable by the target audience
• Not misleading — not omitting material information that would change a reasonable investor's assessment

This means that a firm which does not use any SDR label still cannot make vague claims such as "this fund supports a greener future" without substantiating them. The FCA has made clear it will take action against firms whose marketing does not meet this standard. For investors, this provides a degree of protection even in the unlabelled fund universe.

The Four SDR Labels

The SDR establishes four voluntary labels. Funds do not have to use a label, but if they claim to pursue sustainability objectives, the FCA expects them to be able to justify those claims under the regime.

1. Sustainability Focus

What it means: The fund invests in assets that are already environmentally or socially sustainable, using a robust, evidence-based standard to define what qualifies. The majority (at least 70%) of the portfolio must meet this standard.

Typical fund types: Funds that buy "best-in-class" companies rated highly on ESG criteria, or funds investing in assets with strong environmental credentials such as certified green buildings, renewable energy infrastructure, or companies with verified net-zero transition plans.

What investors should examine: What is the definition of "sustainable"? Who sets it? Is it independently verified, or defined by the fund manager? The label does not mandate third-party verification, so due diligence on the underlying standard remains important.

2. Sustainability Improvers

What it means: The fund invests in assets that may not currently meet a sustainability standard but have credible potential to improve over time. The fund manager takes an active stewardship role in driving that improvement.

Typical fund types: Active equity funds investing in transitioning companies — for example, an oil major with a credible decarbonisation strategy, or a company in a developing economy improving its governance standards. This label is explicitly designed to avoid the criticism that purely "clean" funds simply exclude the companies most in need of change.

What investors should examine: What stewardship activities does the manager actually carry out? What escalation mechanisms exist if a company fails to improve? What is the timeline for expected improvement? The label requires the manager to disclose this, but investors should read the underlying documentation — known as the sustainability product label report — carefully.

3. Sustainability Impact

What it means: The fund aims to achieve a positive, measurable impact on real-world environmental or social outcomes. It must demonstrate additionality — that the impact would not have occurred without the fund's involvement — and measure outcomes against pre-defined targets.

Typical fund types: Private equity or venture capital funds investing in companies directly addressing climate change, healthcare access, or financial inclusion; green bond funds where capital directly finances specific projects; social impact bonds. This is the most demanding label.

What investors should examine: How does the fund demonstrate additionality? In public equity markets, buying shares in a listed company rarely constitutes additionality (the company already raised capital at IPO). Genuine impact in public markets typically requires active stewardship, co-investment in new capital raises, or investment in primary market instruments. Be sceptical of Impact labelled public equity funds that do not clearly explain their additionality argument.

4. Sustainability Mixed Goals

What it means: A fund where different parts of the portfolio pursue different sustainability objectives — some assets may be Sustainability Focus, others Sustainability Improvers, and others may target Impact. The overall portfolio must still have at least 70% allocated to assets with sustainability characteristics.

Typical fund types: Multi-asset funds or blended finance vehicles that mix green bonds, impact equity, and transitioning company equities within a single mandate.

What investors should examine: Mixed Goals funds offer flexibility but can be harder to assess. Request the detailed breakdown of how much of the portfolio falls into each sub-strategy, and assess whether the combination makes sense given your own investment objectives.

Naming and Marketing Restrictions

From December 2024, the FCA restricted the use of sustainability-related terms in fund names. In broad terms:

• Funds using terms such as "sustainable", "responsible", "ESG", "impact", "green", or similar must either hold a label or demonstrate that use of the term complies with the anti-greenwashing rule.
• The restrictions apply to UK-authorised funds marketed to UK retail investors.
• The FCA published a list of terms that would trigger review; fund managers have had to rename or reclassify funds that used these terms without a qualifying label.

This has caused a significant wave of fund renames across the UK industry, parallel to (though separate from) the EU's own reclassification exercise under SFDR.

How SDR Differs from EU SFDR

UK investors often confuse SDR with the EU's Sustainable Finance Disclosure Regulation (SFDR), which applies to EU-domiciled funds — including the UCITS funds commonly available on UK platforms. The key differences are:

Aspect	UK SDR	EU SFDR
Labels	Four voluntary labels	Article 6 / 8 / 9 disclosure categories (not labels)
Threshold	70% of assets must qualify	No mandatory threshold for Article 8
Anti-greenwashing	Explicit rule	Under review; EU strengthening ESMA guidance
Mandatory?	Labels voluntary; anti-greenwashing mandatory	Disclosure mandatory; labels not yet formalised

A fund available in the UK but domiciled in Luxembourg or Ireland will carry SFDR classifications, not SDR labels. UK investors buying UCITS funds need to understand both frameworks. This is discussed further in our guide to EU SFDR Article 8 and Article 9 funds.

What Investors Should Do in Practice

Step 1: Check the label. If a fund is UK-authorised and claims sustainability credentials, look for its SDR label in the Key Information Document, the fund's website, or the KIID/PRIIPs document. The absence of a label does not mean the fund is not sustainable, but it does mean you need to work harder to verify claims independently.

Step 2: Read the sustainability product label report. Labelled funds must publish this document, which discloses the sustainability objective, the investment strategy, the criteria used, stewardship approach, and performance against targets. These reports vary considerably in quality and specificity.

Step 3: Check consistency with your objectives. A Sustainability Improvers fund will hold companies that are not yet sustainable. A Sustainability Focus fund may exclude many sectors you want exposure to. Neither is inherently better; they serve different purposes.

Step 4: Look at the holdings. Marketing literature can be misleading even with regulatory oversight. Reviewing the actual portfolio — available in the fund's periodic disclosures — remains the most direct way to assess whether holdings are consistent with the label claimed.

Step 5: Consider costs. Labelled funds often carry slightly higher ongoing charges due to additional data, reporting, and stewardship costs. This does not automatically make them poor value, but the cost differential should be weighed against the claimed benefit.

What the SDR Does Not Cover

The SDR does not address:

• Overseas funds sold in the UK — these include many UCITS funds from Ireland and Luxembourg, which carry SFDR labels rather than SDR labels.
• Portfolio management services — discretionary managers are not yet subject to the labelling regime, though product-level disclosures are expected.
• Tax-wrapper providers — a Stocks and Shares ISA or SIPP itself cannot hold an SDR label; the label is at the fund level.
• Performance guarantees — no sustainability label implies that a fund will outperform or protect capital.

Regulatory Direction of Travel

The FCA has signalled that the SDR regime will evolve. Consultations are ongoing on extending the regime to portfolio managers and potentially to offshore funds sold in the UK. The FCA is also coordinating with international bodies — including IOSCO and the ISSB — to try to achieve greater cross-border coherence in sustainability disclosure standards over time.

For investors, the practical implication is that the landscape will continue to shift. Funds may acquire or lose labels as their strategies evolve or as regulatory standards tighten. Annual reviews of your fund's label status are advisable.
