The Best Investment Platforms in the UK Compared
Choosing the right investment platform can save you thousands in fees over a lifetime. Here's a detailed comparison of the best UK platforms for 2026.
Why Your Platform Choice Matters
With dozens of investment platforms available in the UK, choosing the right one can feel overwhelming. But the decision matters: fees, fund selection, and user experience vary significantly between providers. Over a 20-year investing horizon, platform fees alone can make a difference of thousands of pounds to your final portfolio value. The key is matching the platform to your investing style, portfolio size, and what you want to invest in.
Hargreaves Lansdown
The UK's largest investment platform with over 1.8 million clients. HL offers the broadest range of investments — thousands of funds, ETFs, shares, investment trusts, gilts, and more — plus excellent research tools and top-rated customer service. The platform fee is 0.45 per cent on funds, capped at £45 per year for shares and ETFs. The dealing fee is £11.95 per trade, dropping to £8.95 for 10 or more trades per month. Best for investors with larger portfolios who want maximum choice and service, though relatively expensive for large fund portfolios.
AJ Bell
A solid mid-tier platform popular with both beginners and experienced investors. AJ Bell offers a good range of investments, competitive fees, and a clean interface. The platform fee is 0.25 per cent on funds, capped at £3.50 per month for shares and ETFs. The dealing fee is £9.95 per trade online, or £1.50 for regular monthly investing. Best for investors who want a balance of price and features.
Vanguard UK
Vanguard's own platform is the go-to choice for fans of low-cost passive investing who are happy to invest exclusively in Vanguard's range. The platform fee is 0.15 per cent per year capped at £375 annually. There are no dealing fees for Vanguard funds and £7.50 per trade for ETFs. Best for passive investors committed to Vanguard funds, particularly those with growing portfolios that benefit from the fee cap. Limited to Vanguard products only — no third-party funds, shares, or investment trusts.
InvestEngine
A rapidly growing platform focusing exclusively on ETF investing. InvestEngine charges no platform fee on DIY ETF portfolios and no dealing fees — making it potentially the cheapest option for ETF-focused investors. The managed portfolio service charges 0.25 per cent. Best for ETF investors who want the lowest possible costs. No individual shares or investment trusts available.
Trading 212
One of the most popular apps for younger and beginner UK investors. Trading 212 offers commission-free trading in shares and ETFs, plus fractional shares from £1. The Pie investing feature allows automatic portfolio rebalancing. No platform fee, no dealing fee, no ISA fee. Best for beginners wanting to start small. UK FCA regulated with FSCS protection up to £85,000.
Freetrade
Another commission-free trading app with a clean, modern interface. Freetrade offers a free basic account and a Plus tier at £5.99 per month which includes the ISA wrapper. No dealing fees. Best for younger investors comfortable with an app-first experience, though the fund and ETF selection is smaller than HL or AJ Bell.
Interactive Investor
Uses a flat-fee subscription model rather than percentage-based charging — making it particularly cost-effective for larger portfolios. The Starter plan is £4.99 per month, Investor is £11.99 per month, and Super Investor is £19.99 per month. One free trade per month is included on most plans. Best for investors with portfolios above £30,000 to £50,000 where flat fees beat percentage charges.
Choosing the Right Platform for Your Situation
If you are starting out with £50 per month, Trading 212, Freetrade, or InvestEngine offer zero fees with no minimum. If you are building a passive ISA portfolio, Vanguard UK or InvestEngine provide the lowest costs for index fund and ETF investors. If you want maximum investment choice, Hargreaves Lansdown or AJ Bell are the best options. If your portfolio exceeds £50,000, Interactive Investor or Vanguard (if using Vanguard funds exclusively) are worth considering to benefit from fee caps or flat fees.
