Quick answer: Ethical, ESG and sustainable pension funds screen out sectors like tobacco, weapons and fossil fuels while still aiming for long-term growth. Widely used UK options include the Royal London Sustainable range, Legal & General Future World, Aviva Stewardship and low-cost ESG index trackers. The 'best' depends on how strict you want the screening and whether you prefer active or passive management.
What are the best ethical pension funds?
Ethical, ESG and sustainable pension funds let you avoid sectors many people object to — typically tobacco, controversial weapons, gambling and fossil fuels — while still aiming for long-term growth. Options widely available inside UK pensions include the Royal London Sustainable range, Legal & General Future World, Aviva Stewardship, the Baillie Gifford Positive Change fund and low-cost ESG index trackers from providers like L&G and HSBC. There is no single "best" fund — the right one depends on how strict you want the screening and whether you prefer active management or a cheaper passive tracker.
Types of ethical pension fund
Approach
What it does
Example fund families
ESG-integrated / "light green"
Considers environmental, social and governance risks but screens out little; usually the cheapest
L&G Future World, HSBC ESG trackers
Ethical / SRI screened
Actively excludes sectors like tobacco, weapons and fossil fuels
Royal London Sustainable, Aviva Stewardship
Sustainable / impact / "dark green"
Actively invests in companies solving environmental or social problems
Fund names, availability and charges change, and past performance does not guarantee future returns — always check the current factsheet and the fund's own exclusion policy before investing.
How to choose an ethical pension fund
Decide how strict you want to be. A light-green ESG tracker keeps costs low but excludes little; a dark-green sustainable fund screens hard but usually costs more and can perform very differently to the wider market.
Look under the bonnet. Two "sustainable" funds can hold very different companies. Read the top holdings and the exclusion policy, not just the label.
Mind the charges and concentration. Actively managed ethical funds carry higher ongoing charges and can be concentrated in a few sectors (like technology or clean energy), which increases ups and downs.
Check it is available in your pension. Most modern SIPPs and many workplace pensions offer a sustainable option or a dedicated ethical default — you can often switch online.

Not necessarily. Ethical and sustainable funds can perform better or worse than the wider market in any given period, partly because they hold different companies and can be concentrated in certain sectors. Past performance does not guarantee future returns, and charges on actively managed ethical funds tend to be higher than on plain index trackers.
ESG-integrated funds simply factor in environmental, social and governance risks but screen out little. Ethical or SRI funds actively exclude sectors such as tobacco, weapons and fossil fuels. Sustainable or impact funds go further and deliberately invest in companies solving environmental or social problems. The labels are not standardised, so always read the fund's own policy.
Usually yes. Most modern SIPPs and many workplace pensions offer a sustainable option or ethical default, and you can often switch online without moving providers. If your current scheme has limited choice, transferring to a provider with a wider fund range is an option — but check for exit penalties or safeguarded benefits first.
Often, yes. Actively managed ethical and sustainable funds usually carry higher ongoing charges than plain index trackers, though low-cost ESG index funds have narrowed the gap. Higher charges eat into long-term growth, so weigh the cost against how important strict screening is to you.
