Best Stocks & Shares ISA Apps in 2026
A Stocks and Shares ISA shelters your gains and dividends from tax — but ISA fees vary wildly, from completely free apps to platforms charging both a wrapper fee and dealing commissions. We ranked UK apps that offer an ISA on total cost and usability. Here is our top pick, followed by the full ranking.

The ranked list
1. Lightyear
5/5Lightyear is a UK- and EU-available investing app offering commission-free stocks and ETFs, a very low currency-conversion fee, and interest on uninvested cash. UK personal accounts (GIA and Stocks & Shares ISA) pay just 0.10% FX; EU accounts pay 0.35%. There are no account, withdrawal or inactivity fees, and no minimum deposit — making it one of the cheapest ways to hold a global portfolio.

3. Robinhood
4.8/5Robinhood pioneered commission-free trading in the US and now offers UK investors commission-free US shares with a very low 0.10% FX fee and a free Stocks & Shares ISA. It trades US-listed stocks, ETFs and options — no UK-listed shares, and no crypto in the UK. A clean app that is light on research; note the $100 account-transfer-out fee.

4. Revolut
4.8/5Revolut bolts simple stock investing onto its popular banking app. Convenient if you already use Revolut, with one free trade per month on Standard, but the 0.25% per-trade commission makes it pricier than dedicated low-cost brokers for active investors.

5. InvestEngine
4.6/5InvestEngine is a UK ETF-only investment platform with no platform fee, no dealing commission and no FX fee on its DIY portfolios, across ISA, SIPP and General accounts. All ETFs are GBP-denominated, so you pay only the underlying ETF's ongoing charge. ETFs only — no individual stocks.

6. Freetrade
4.4/5Freetrade is a UK mobile-first investing app offering commission-free trading on stocks, ETFs and investment trusts, with a genuinely free Stocks & Shares ISA and SIPP on its Basic plan. The main cost for most users is the FX fee on non-GBP trades: 0.99% on the free plan, dropping to 0.59% (Standard, £5.99/mo) and 0.39% (Plus, £11.99/mo).

7. Vanguard UK
3.8/5Vanguard's UK platform charges 0.15% a year capped at £375, with no dealing charges on its funds. It is one of the cheapest ways to hold a simple index portfolio, with two significant caveats: you can only buy Vanguard's own funds and ETFs, and accounts below £32,000 now pay a £4 monthly minimum fee, which is expensive on a small pot.

8. AJ Bell
3.4/5AJ Bell is a long-established UK platform that repriced on 1 May 2026. Its custody charge is 0.25%, tiering down on funds above £250,000, and — crucially — capped at just £3.50 a month on shares, ETFs and investment trusts. That cap makes it one of the cheapest mainstream platforms for a large ETF or share portfolio held in an ISA.

9. interactive investor
3.3/5interactive investor is the UK's main flat-fee platform: you pay a fixed monthly subscription rather than a percentage of your portfolio. That makes it expensive for a small pot and progressively cheaper as the portfolio grows, with the crossover against percentage-fee rivals typically falling somewhere in the low tens of thousands of pounds.

10. Hargreaves Lansdown
3.2/5Hargreaves Lansdown is the largest investment platform in the UK, offering the widest fund range, strong research and well-regarded service. It repriced on 1 March 2026, cutting the account charge from 0.45% to 0.35% and capping the charge on shares at £12.50 a month. It remains a percentage-fee platform, so it is competitive for smaller portfolios of funds and expensive for large ones.

11. Fidelity
3.1/5Fidelity Personal Investing charges a 0.35% service fee that tiers down above £250,000, with a flat £7.50 a month for accounts under £25,000 that have no regular savings plan. Its most useful feature for cost-conscious investors is the £90-a-year cap on the service fee for shares, ETFs and investment trusts held in an ISA or SIPP.

How to choose
First, prefer a free ISA wrapper — several good apps now charge nothing for it. Then look at the costs inside the wrapper: dealing commissions, FX fees on US shares, and fund ongoing charges. Check whether the ISA is flexible (withdraw and replace within the same tax year). Tax treatment depends on your individual circumstances and ISA rules can change.
How we rank
Rankings are based on published fees, regulatory standing, available features, and the real cost of common actions (trading, withdrawing, currency conversion). We do not accept payment for placement; affiliate relationships do not influence the order. The fee data behind this ranking comes from the same verified dataset as our UK Broker Fee Index — a quarterly data study where FX fees alone vary almost tenfold between platforms.
