"Best" means something different to almost every investor. A platform that's ideal for a hands-off ISA saver buying a couple of index funds a year looks very different from the best fit for an active trader who wants access to a huge range of individual shares and real-time data. Rather than chasing a single "best overall" answer, it's more useful to compare platforms against the handful of things that actually matter for how you plan to invest.
1. The criteria that matter most
Fees, relative to how you'll actually use the platform
Look past the headline percentage and think about your own likely portfolio size and trading frequency. A percentage-based fee can work out cheaper for a smaller portfolio, while a flat fee often wins out once your balance grows past a certain point. Our cheapest investing platform guide breaks this down in more detail.
Range of investments available
Check whether a platform offers the specific things you want to invest in — individual UK and international shares, a broad range of ETFs, investment trusts, or actively managed funds. Not every platform offers the full range, and some specialise more heavily in one area than another.
Account types on offer
Confirm the platform supports the account type you actually need, whether that's a Stocks and Shares ISA, a SIPP, or a general investment account, since not every platform offers all three.
Usability
If you're new to investing, a cluttered, trading-focused interface can be genuinely off-putting. Our best platform for beginners guide focuses specifically on platforms designed to be approachable for first-time investors.
Customer service and support
Investing platforms hold significant sums of your money, so it's worth checking how easy a provider is to contact if something goes wrong, and whether it has a track record of resolving issues without excessive delay.
2. Don't overlook regulation
Whichever platform you're drawn to, confirm it's authorised by the UK's Financial Conduct Authority, which means your cash and investments are protected by the Financial Services Compensation Scheme up to £85,000 if the platform itself were to fail.
3. Comparing platforms for different goals
- If you're saving specifically for retirement, compare our dedicated best SIPP platform guide, since pension-specific features and fees matter more here than general platform comparisons.
- If tax-free growth on shares and funds is your priority, our best Stocks and Shares ISA platform guide focuses specifically on that account type.
- If you're just starting out, see our best platform for beginners guide for platforms that prioritise simplicity over advanced trading tools.
4. Frequently asked questions
Is the platform with the lowest fee always the best choice?
Not necessarily. A very cheap platform that doesn't offer the account type or investment range you actually need isn't good value, however low its headline fee looks. Match the platform to your specific goals first.
How many platforms should I compare before choosing?
There's no fixed number, but it's worth comparing at least three or four against your specific priorities — fees, account type, investment range and usability — rather than picking the first name you recognise.
Can I switch investing platforms later if I change my mind?
Yes, most platforms support transferring your existing ISA, SIPP or general investment holdings to a new provider, though the process and any charges involved vary, so check the specific transfer terms before committing long-term.
Do all investing platforms offer the same range of shares and funds?
No, the range varies significantly between platforms. If you want to invest in a specific fund, ETF or international market, check it's actually available before assuming every platform offers it.
5. Conclusion
The best investing platform for you depends on your specific goals, not a single universal ranking. Work out what account type you need, how you're likely to use the platform, and how much that's likely to cost given your typical portfolio size, then compare the specific guides above for a more targeted recommendation.
