Quick Answer
To avoid greenwashing in the UK, look beyond fund names and brochures. Check the FCA's SDR label (or its absence), read the KIID and prospectus for the binding sustainability policy, inspect the top-10 holdings against the stated theme, review the manager's exclusions list and stewardship record, and cross-check ESG ratings from more than one provider. Vague language and missing evidence are the clearest red flags. Capital is at risk.
Greenwashing is the gap between what a fund claims and what it actually owns or does. The FCA's anti-greenwashing rule, in force since 31 May 2024, requires UK firms to ensure that sustainability-related claims are clear, fair and not misleading. The Sustainability Disclosure Requirements (SDR) and four investment labels go further — funds using sustainability terms in their name must either earn a label or comply with naming and disclosure rules.
That regulation helps, but the responsibility still sits with the investor (and adviser) to look under the bonnet. Below are the red flags I look for first, and the practical checks that follow.
Six Red Flags
| Red flag | What it tells you |
|---|---|
| Vague language | 'Sustainable', 'green' or 'responsible' with no defined methodology or exclusions |
| No exclusions list | Fund won't say what it refuses to hold (fossil fuels, weapons, tobacco) |
| Heavy oil & gas weighting | Top-10 holdings include integrated oil majors despite a 'climate' label |
| No SDR label (UK funds) | Marketed as sustainable to UK retail investors but hasn't adopted an FCA SDR label |
| Thin reporting | No annual stewardship or impact report; no voting record disclosed |
| Score-only screening | Relies entirely on third-party ESG ratings with no manager conviction |
Six Checks That Actually Work
None of these are exotic — they are the same checks an adviser runs during fund due diligence. You can do most of them in 20–30 minutes per fund.
| Check | Why it matters |
|---|---|
| Read the KIID and prospectus | Confirms the binding policy — marketing material is not binding |
| Check the SDR label | FCA's four labels (Focus, Improvers, Impact, Mixed Goals) require evidence |
| Inspect top-10 holdings | Look at what's actually in the fund, not the brochure |
| Review the exclusions list | Hard exclusions are stronger evidence than 'best-in-class' tilts |
| Read the stewardship report | How does the manager vote and engage on climate, pay and governance? |
| Cross-check against ratings | MSCI, Morningstar Sustainability and CDP ratings give a second view |
Understanding the FCA's SDR Labels
The four labels are the single most useful tool a UK retail investor now has against greenwashing. Each requires at least 70% of fund assets to align with a documented sustainability objective, evidenced by a credible standard or methodology.
- Sustainability Focus — invests in assets already meeting a credible sustainability standard.
- Sustainability Improvers — invests in assets with potential to improve, with stewardship plans.
- Sustainability Impact — aims to achieve a positive, measurable real-world outcome.
- Sustainability Mixed Goals — combines two or more of the above strategies.
Where Funds Often Fall Short
Naming a fund 'Climate' or 'Transition' while the top holdings remain integrated oil majors
Reporting carbon intensity but not absolute emissions or scope-3 exposure
Excluding controversial weapons but holding tobacco, gambling or fossil-fuel expansion
Voting with management on every climate resolution despite a 'stewardship' narrative
Using a single ESG rating provider as the only evidence base
Charging an active fee for what is effectively a tilted tracker
Where Advice Helps
A specialist ethical adviser does this work as a matter of routine — reading the KIIDs, comparing SDR disclosures against actual holdings, and matching fund choices to the values you've articulated rather than the labels marketing teams have chosen. That's the difference between owning an "ethical" portfolio and owning one whose evidence holds up under scrutiny.
