What is an investment platform?

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.

How to choose the right platform

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 (from £4.99/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 and Vanguard offer free ISAs with no platform charge. Freetrade charges £5.99/month for ISA access. Hargreaves Lansdown charges 0.45% of your portfolio value. 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.

Platform fees explained: percentage vs flat

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.

Percentage-based fees

Platforms like Vanguard (0.15%), AJ Bell (0.25%), and Hargreaves Lansdown (0.45%) charge a percentage of your total portfolio value each year. This means the cost grows as your investments grow. A 0.45% fee on a £10,000 portfolio is £45/year, but on a £200,000 portfolio it becomes £900/year.

Flat fees

Interactive Investor charges a fixed monthly amount (from £4.99/month). This stays the same regardless of portfolio size, making it increasingly good value as your portfolio grows. At £11.99/month (£143.88/year), it becomes cheaper than Hargreaves Lansdown once your portfolio exceeds roughly £32,000.

The zero-fee exception. Trading 212 charges neither a percentage fee nor a flat fee on the Stocks & Shares ISA. This makes it the cheapest option at virtually any portfolio size, although its fund selection is more limited than Hargreaves Lansdown or AJ Bell. For most beginners and intermediate investors, the available ETFs and shares on Trading 212 are more than sufficient.

Best for beginners: Trading 212

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.

Best for index funds: Vanguard

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 — at a platform fee of just 0.15% (capped at £375/year).

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.

Best for fund choice: Hargreaves Lansdown

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.

The downside is cost. The 0.45% platform fee is among the highest of major UK platforms. On a £100,000 portfolio, that is £450/year — compared to £150 on Vanguard or £0 on Trading 212. For experienced investors who value breadth of choice and premium research, HL remains a strong option. For cost-conscious beginners, it is unnecessarily expensive.

FCA regulation explained

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.

FSCS protection: what is covered

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.
