Best Investment Platforms
UK (2026)

An investment platform (also called a fund supermarket or broker) is a service that lets you buy and hold investments like shares, funds, ETFs, and bonds. Think of it as a digital home for your investments. Most platforms in the UK also offer tax-efficient wrappers such as Stocks & Shares ISAs and Self-Invested Personal Pensions (SIPPs).

When you invest through a platform, the platform holds your assets on your behalf. Your investments are legally separated from the platform's own assets, which means if the company goes bust, your investments are ring-fenced and returned to you. On top of this, the Financial Services Compensation Scheme (FSCS) provides protection up to £85,000 per provider.

All legitimate UK investment platforms must be authorised and regulated by the Financial Conduct Authority (FCA). You can check any platform's regulatory status on the FCA Register. Every platform we compare on this page is FCA regulated.

The "best" platform depends entirely on your situation. Here are the key factors to consider when choosing where to invest your money.

Portfolio size matters. If you are investing under £20,000, a zero-fee platform like Trading 212 is almost always the cheapest option. As your portfolio grows past £50,000, flat-fee platforms like Interactive Investor (Core from £5.99/month) become better value than percentage-based platforms, where the fee grows with your balance.

Think about what you want to invest in. If you want access to thousands of funds and detailed research, Hargreaves Lansdown offers the widest selection. If you are happy with a simple global index fund approach, Vanguard or Trading 212 will serve you well at a much lower cost. If you want to pick individual shares, Trading 212 or Freetrade offer commission-free stock trading.

Consider the ISA cost. Trading 212 offers a completely free ISA with no platform charge. Vanguard charges a flat £4/month (£48/year) on balances under £32,000, then 0.15% up to a £375/year cap. Freetrade now includes the Stocks & Shares ISA (and SIPP) on its free Basic plan, a January 2026 change most comparison sites have not yet caught up with. Hargreaves Lansdown charges 0.35% up to £150/year per account from March 2026. Over many years, these fee differences compound significantly.

Check the user experience. If you are a beginner, a clean mobile-first app like Trading 212 is far less overwhelming than a traditional broker interface. Conversely, experienced investors may want the depth of tools that Hargreaves Lansdown or AJ Bell provide.

Investment platform fees in the UK generally fall into two models: percentage-based fees and flat fees. Understanding the difference is crucial because the wrong choice can cost you thousands over a long investing lifetime.

Trading 212 is our top recommendation for anyone new to investing in the UK. The combination of zero fees, a £1 minimum investment, and an exceptionally well-designed app removes every barrier to getting started.

The platform supports fractional shares, meaning you can invest in expensive stocks like Amazon or Berkshire Hathaway with just £1. The auto-invest "Pies" feature lets you set up automated portfolios that rebalance automatically, ideal for a set-and-forget approach.

Trading 212 UK Ltd is authorised and regulated by the Financial Conduct Authority (FRN: 609146). Client funds are held in segregated accounts, and investments are protected by the FSCS up to £85,000. Over 2 million UK investors now use the platform.

The main limitation is the fund selection. Trading 212 offers thousands of stocks and ETFs, but fewer managed funds compared to Hargreaves Lansdown. For most beginners investing in ETFs and index trackers, this is not a practical constraint.

Vanguard is the world's second-largest asset manager and the pioneer of index fund investing. Their UK platform offers around 80 Vanguard funds, including the hugely popular FTSE Global All Cap Index Fund and LifeStrategy range. From February 2025, the platform charges £4/month (£48/year) on balances below £32,000, then switches to 0.15% a year (capped at £375) once you cross that threshold. This change made Vanguard relatively more expensive for small portfolios and is worth factoring in if you are starting out, our breakdown of which platform wins on fees over 10 years shows the real-money impact of the restructure on a £200/month investor.

Vanguard's unique structure means the company is owned by its funds, which are in turn owned by their investors. There are no external shareholders pushing for higher profits, which is why Vanguard consistently offers some of the lowest fund charges in the industry.

The trade-off is simplicity. You can only buy Vanguard funds on the Vanguard platform, no individual shares, no third-party funds, no ETFs from other providers. For many investors, this is actually an advantage: fewer choices mean fewer chances to make costly mistakes. If you want a single global index fund and nothing else, Vanguard is hard to beat.

Hargreaves Lansdown (HL) is the UK's largest investment platform by assets under administration. It offers the widest selection of funds, shares, investment trusts, ETFs, and bonds of any UK platform, over 3,000 funds from hundreds of providers.

Their Wealth Shortlist highlights HL's top-rated funds across every sector, making it easier to narrow down the overwhelming choice. The research tools, fund factsheets, and educational content are the best in the UK market.

Cost was historically HL's weak point, and it has improved materially. From 1 March 2026, the annual account charge dropped to 0.35% and is capped at £150/year per account type (ISA, SIPP, Fund & Share). Share dealing was cut from £11.95 to £6.95 per trade, but a new £1.95 charge applies to fund dealing (free regular monthly investing remains). On a £100,000 ISA, the £150 cap now bites hard, you pay £150/year rather than the £450/year the old 0.45% structure implied. Still pricier than Vanguard or Trading 212 for small portfolios, but the gap is meaningfully narrower.

The Financial Conduct Authority (FCA) is the UK's financial regulator. Any company offering investment services in the UK must be authorised by the FCA, which means they must meet strict standards for how they handle your money, manage conflicts of interest, and communicate with customers.

FCA regulation ensures that platforms keep your money in segregated accounts (separate from the company's own funds), provide clear fee disclosure, treat customers fairly, and maintain adequate capital reserves. You can verify any platform's FCA status on the FCA Register.

The Financial Services Compensation Scheme (FSCS) is the UK's statutory deposit insurance and investment protection scheme. If an FCA-regulated investment platform fails, the FSCS can compensate you up to £85,000 per provider.

It is important to understand what FSCS does and does not cover. FSCS protects you if the platform company itself goes bust, for example, due to fraud or insolvency. It does not protect you against losses from market movements. If you invest £10,000 and the stock market falls 20%, you have lost £2,000 regardless of FSCS. The scheme only kicks in if the platform itself fails and cannot return your assets.

Because your investments are held in segregated accounts, platform failure rarely results in total loss. In most cases, your assets would simply be transferred to another provider. FSCS is a backstop for the unusual scenario where segregation fails.
