The growing demand for ethical investment ISAs
One of the biggest trends we have seen in investments over recent years has been the move to ethical investing. Morningstar states there are now around $3.2trn in assets under management in sustainable funds globally. This means there is also a growing demand for ethical ISAs among UK investors, who are keen to combine the tax-saving efficiency of the ISA wrapper with the potential to invest in line with their principles.
The growth in ethical ISAs has been two-pronged: we have witnessed a number of ethical banks and ethical investment companies springing up to meet demand, as well as more traditional investment platforms adding an ethical dimension to their existing proposition. The result is a great deal of choice for consumers, whether they are looking for ESG, socially responsible investing (SRI), impact investing or sustainable investing options.

Moneyfarm Ethical ISA - Special offer - Pay no fees for the first year
Moneyfarm* offers a range of socially responsible investing (SRI) portfolios optimised for factors such as environmental risk, CO2 intensity, controversy avoidance, and other similar metrics. The 7 portfolios prioritise environmental, social and corporate governance factors, often referred to as ESG. The portfolios are built in the same way as regular portfolios, with Moneyfarm selecting the best-in-class ETFs, and an additional layer of negative screening ensures that companies involved in arms production and the burning of fossil fuels are automatically excluded.
The annual fees for Moneyfarm's actively managed ethical portfolios are now split into a platform fee and a tiered management fee, meaning the overall percentage you pay decreases as you invest more. The platform fee is set at 0.25% (with a minimum charge of £1.25 per month). On top of this, the management fee starts at 0.45% for portfolios up to £50,000. The management fee drops to 0.20% for investments between £50,000 and £100,000, and reduces further to just 0.10% for balances between £100,000 and £1.5 million. Once you have over £1.5 million invested, Moneyfarm waives the management fee entirely. Ongoing fund costs for the ethical portfolios remain very low, averaging 0.24%.

Wealthify Ethical ISA - Low management fees
Wealthify offers five ethical portfolios that invest in organisations that are committed to having a positive impact on society and the environment. Ranging from 'cautious' to 'adventurous', the five risk-based plans receive rigorous ongoing screening, ensuring that ethical standards are maintained. All fund providers are signatories of the Principles of Responsible Investing (PRI), a United Nations-supported network of investors that work together to promote responsible investing.
Wealthify charges a low management fee of just 0.60%, which is the lowest of all the robo-advisors if investing less than £50,000. In addition, investors have to pay fund charges that average around 0.46%.
J.P. Morgan Personal Investing Ethical ISA - Good for managed portfolios with a track record
J.P. Morgan Personal Investing (formerly Nutmeg) stands out in the ethical ISA sphere because of the fact it gives all of its portfolios - even those that are not specifically "SRI" - a score out of 10 for their ethical credentials. This is judged against 15 criteria across the environmental, social and governance categories and makes it exceptionally easy for investors to get an understanding of the nature of the investment. Over and above that, its 10 specific SRI portfolios, which range in risk from low to high, are focused on avoiding companies engaged in "controversial activities" and towards those that rank highly against the ESG criteria.
The annual fees for the SRI portfolios stand at 0.75% for investment pots up to £100,000 and 0.35% for those over £100,000, which is the same cost as for its standard fully managed portfolios. Investors will also have to pay the underlying fund charges, which average around 0.27%, compared with 0.22% for J.P. Morgan Personal Investing's fully managed portfolios.
Compared with some other robo-advisors, J.P. Morgan Personal Investing has a much longer track record as it launched in 2012. Over that time its portfolios at the riskier end of the spectrum have tended to perform better against its rivals, even within its newer SRI portfolios.
Interactive Investor - Best for those who want to choose their own investments
Interactive Investor* differs from the robo-advice platforms by offering an environment where DIY investors are provided with the tools they need to build and manage their own investment portfolios.
When it comes to ethical investing, Interactive Investor has revamped its proposition. Moving away from its previous "ACE 40" list, the platform now offers a data-driven Sustainable Investment Screener. Because there is no single "right way" to invest ethically, this tool relies on independent Morningstar data to help investors filter a vast universe of funds, investment trusts, and ETFs based on their personal values, all while ensuring protection against "greenwashing."
Investments are categorised into three clear sustainable styles based on their objectives:
- General ESG Investment - Funds that integrate environmental, social, and governance (ESG) criteria into the core of their investment process.
- Sustainability Themed Investment - Funds focused on long-term global goals, such as human development or climate action.
- Employs Exclusions - Investments that deliberately strip out controversial sectors and practices, such as fossil fuels, tobacco, or animal testing.
Alongside the screener, the platform provides helpful educational resources, including a sustainable investment jargon buster, to help investors strike the right balance between doing social or environmental good and achieving strong financial returns. If you want to invest ethically and choose your own investments, Interactive Investor is leading the way in the platform space.
The tools provided are good quality and the site as a whole is easy to navigate. Interactive Investor charges a flat-fee structure with its lowest 'Core' plan priced at just £5.99 per month if investing less than £100,000. Those investing more than £100,000 will be moved up to the £14.99 per month subscription, however, that does include a free trade each month, a saving of £3.99.

Bestinvest - Good for those wanting flexibility
Bestinvest* is part of Evelyn Partners (formerly known as Tilney Smith & Williamson) and it offers a broad range of financial planning, investment planning and investment advice services. It is one of only a few providers that offer a 'Flexible ISA', letting you withdraw money from your ISA temporarily and then pay it back within the same tax year. Crucially, this doesn't affect your annual ISA allowance. Additionally, Bestinvest pays 2.98% interest on uninvested cash.
In terms of its ethical offering, Bestinvest has an investment search tool which allows investors to easily navigate and filter sustainable options. It also offers two ready-made portfolios that focus on environmental and social characteristics. To comply with new regulatory fund naming guidelines, Bestinvest rebranded these from "Sustainable" portfolios to the "Horizon" range in April 2025. You can find them listed as the 'Horizon Cautious' and 'Horizon Adventurous' options.

Best ethical ISA from specialist ethical providers
The Big Exchange
Originating from the Big Issue Group, The Big Exchange launched in October 2020 as an investment platform with the worthy aims of "transforming financial services and building a fairer financial system for everyone". For its investment option, this means implementing a bespoke fund screening process based specifically on the United Nations' Sustainable Development Goals. This filters through to three risk-rated portfolios - named "bundles" by The Big Exchange.
A criticism levelled at ethical portfolios is they often opt for passive vehicles as a way to keep costs down, but this can reduce the manager's ability to keep to their ethical mandate. The Big Exchange, however, has deliberately chosen actively managed funds, with the rationale that this facilitates more mindful stock selection in line with ethical principles rather than just screening out the worst offenders in any given sector.
In terms of fees, it charges a platform fee of 0.25%, which is relatively competitive. The underlying fund costs are obviously higher than with portfolios based around passive vehicles and typically range from 0.5% to 1.8% per year (averaging around 0.88% for its Balanced bundle). Overall, having launched over five years ago, The Big Exchange has built an established track record and proven itself to be a viable proposition attractive to those with more finely tuned ethical requirements for their investments.

Triodos
Triodos is an ethical bank that offers a cash ISA, junior ISA and Stocks and Shares ISA. Unlike the other ISAs in this review, Triodos offers direct investments into its own actively managed funds rather than a portfolio of funds. At the time of writing, the available options are the large-cap focused Triodos Global Equities Impact fund, the small-and-mid cap orientated Triodos Pioneer Impact fund, Triodos Sterling Bond Impact fund, and the more recently launched Triodos Future Generations Fund (a unique thematic fund supporting UNICEF by investing in companies that contribute to the well-being and development of children).
In a similar way to The Big Exchange proposition, Triodos is a good option for those looking for actively managed, ethically driven investments rather than a cover-all passive alternative. The costs are in line with what you would expect to pay to invest in a single fund investment. In 2026, Triodos is rated 4.5 out of 5.0 based on around 800 reviews. Overall, it's a bolder choice than those offered by the platforms as it is centred on single funds, meaning it is probably better suited to investors with some prior experience of the markets.
How to choose the best ethical ISA for you
As the number of ethical ISAs available continues to skyrocket, it pays to carefully consider what it is you are looking for from this investment vehicle. While they will all share the tax-efficiency of all ISAs, allowing you to pay in up to £20,000 per year tax free, they each offer slightly different features, particularly in terms of how they service the "ethical" part of the equation.
When you are considering the options available, ask yourself:
- What are your priorities with ethical investing? - Are you looking for an investment that addresses a particular issue - for example, climate change - or are you happy to simply screen out some of the more controversial stocks that are having an actively detrimental impact? Look at the individual providers' investment philosophy and how they implement them in the choices they make and the strategies they employ.
- How important is cost? - Would you rather use low-cost passive funds or would you rather pay extra for actively managed funds that perhaps apply greater scrutiny to the ethical credentials of the underlying holdings? Are you willing to take on extra risk in order to secure a higher return or tap into a particular theme that fits more closely with your principles?
- What is the track record of the provider and the funds they invest in/manage? - There is a great deal of innovation in this space but in some cases the strategies are untested and unproven.
- How much choice do you need and how confident are you in making investment decisions? - This will help determine whether a ready-made portfolio is suitable or if a platform that allows more autonomy in investment choice is better.
Summary - Should you get an ethical ISA?
The ethical investment trend is here to stay and, indeed, looks set to grow further. There are many ethical ISA choices available - as demonstrated above - and there should be something to suit most people. As ethical investing moves more firmly into the mainstream, the number of options is likely to increase further and the sector as a whole become more sophisticated. Ethical investments have a decent track record when compared to the broader market, meaning ethical investors do not necessarily need to compromise performance for their principles. However, it is worth noting that volatility had a significant impact on the performance of many ethical funds in 2022, much of this being put down to ethical funds often favouring technology stocks, thanks to their lower carbon footprints.
