The top stocks & shares ISAs to build wealth in 2025

With the start of the new tax year comes a fresh chance to invest in your finances and consider new opportunities. Stocks & Shares ISAs allow you to invest tax-free into businesses, commodities, funds, and more by opening an account with an investment platform and choosing which shares or funds you’d like to buy.

You can now use multiple Stocks & Shares ISAs after the ‘one per year’ limit was scrapped in 2024, with a £20,000 annual deposit limit split across all ISAs.

With this in mind, Damien Jordan, founder of Financial Interest and Damien Talks Money has reviewed the best stocks and shares ISAs for 2025.

Best Overall Stocks & Shares ISA – Trading 212

“Trading 212 offers fractional stocks and ETFs with no trading commissions, no account management fees, and a best-on-the-market FX rate of just 0.15% — a figure that’s literally 10% of what some competitors charge. You can also avoid it by just buying investments listed in pounds, so you can completely avoid paying any fees directly to Trading 212.

“This flexible Stocks & Shares ISA allows you to withdraw and re-deposit in the same tax year without affecting your annual ISA limits, withdrawals are lightning-quick whenever we’ve tested, and you can deposit and withdraw for free.

“Trading 212 offers the ability to buy over 3,000 exchange traded funds including a whole host of the most popular Vanguard, Blackrock and Invesco funds as well as other providers.

They also offer more niche fund choices in varying asset classes and they list thousands of individual companies from loads of global markets as well.”

Best for ETFs – InvestEngine

“InvestEngine is really well suited to investors who just want to buy index funds, offering 795 exchange traded funds currently – and this is constantly going up. They have access to all the big name providers that you would hope to see, giving you lots of choice. It’s also really simple to use and you could use the app without any instruction, with details of investments clearly presented and the ETF filters are a great way to sort through them. There’s also a portfolio builder tool that’s really easy to use and their saving plan feature automates deposits via a direct debit for you.

“The ISA is also flexible so you can take any amount of money out that’s inside your stocks and shares ISA and as long as you pay it back within the same financial year, it won’t use up that year’s ISA allowance. When it comes to fees, you can invest with InvestEngine without them charging you any trading commissions or account fees, and all investments are listed in pounds so foreign exchange fees aren’t possible.”

Best for Mutual Funds – iWeb

“iWeb has a really compelling offer because of how low you can get the fees on mutual funds. They’re part of the Lloyds Banking Group and offer all types of investing and allow you to invest on the mutual funds side for just a £5 fixed fee, and they’ve scrapped their £100 joining fee. In theory, you could hop on this platform once a year, fill up your ISA and buy your favourite mutual fund and pay only £5 in fees to iWeb. Compared to Vanguard and others, you can save a lot of money with iWeb if you’re someone who invests big lump sums at once.”

Best for Kids –  Hargreaves Lansdown

“Hargreaves Lansdown tends to be more on the expensive side than many other brokers but what’s brilliant is that their Junior ISA is free. The benefits of this account are massive as you’re getting all the access to the HL platform and all its perks, which usually comes with higher fees, for free when you use it to invest on behalf of children.”

Best for Active Traders – Interactive Brokers

“Interactive Brokers (IBKR) is for people who really want to actively manage their portfolio and are looking for sophisticated tools to do so. The trade off with IBKR is that it may be hard to use and even to understand their fee structure, but it does let you perform more complicated actions than just passively buying an index fund.”

Damien finished by commenting: “If you’re looking to invest in stocks, index funds or ETFs, bonds, or anything remotely similar to these things, there is one main benefit of choosing to invest inside a Stocks and Shares ISA: you don’t pay any tax on returns from your investments. If you invest outside of an ISA, you’ll owe capital gains tax on your profits, which can add up to huge amounts over time. And whilst the world of investing and ISAs can seem confusing, it’s actually really simple to get started. You can also check out this free tool to compare Stocks and Shares ISAs.”
