Have you ever stared at a stock market chart, heart racing, wondering how to jump into the world of investing without getting burned? I know I have. The UK’s trading platforms have exploded in popularity, with millions of DIY investors taking control of their financial futures. But with so many options out there, how do you pick the one that’s right for you? Whether you’re a newbie dipping your toes or a seasoned trader juggling a hefty portfolio, choosing the right platform can make or break your investment journey. Let’s dive into the best trading platforms for UK investors in 2025, ranked by cost, features, and user experience, with a sprinkle of personal insight to help you navigate this crowded space.
Why Choosing the Right Trading Platform Matters
The rise of DIY investing has transformed how we approach wealth-building. Since 2020, over 10 million investment accounts have popped up across the UK, driven by user-friendly apps and a hunger for financial independence. But here’s the kicker: not all platforms are created equal. A seemingly small difference in platform fees or trading costs can shave thousands off your returns over time. Imagine investing £50,000 at a 10% annual growth rate. After 20 years, a platform with zero fees could grow that to £336,000, while one charging 0.45% annually might cost you nearly £30,000 in lost gains. Ouch. That’s why we’ve analyzed the top platforms to help you make an informed choice.
Top Pick for Cost-Conscious Investors
If keeping costs low is your priority, one platform stands out for its commission-free trading and sleek app design. This UK-based fintech, recently snapped up by a larger financial player in 2025, boasts over a million users and offers a range of accounts, including ISAs and SIPPs. You get access to nearly 6,000 UK, European, and US shares, plus 600 ETFs and investment trusts. The catch? Actively managed funds are locked behind a premium plan, but for most investors, the free tier is more than enough to get started.

What makes this platform shine is its simplicity. The app’s interface feels like it was designed with beginners in mind, though it might lack the in-depth research tools some veterans crave. Plans range from a free basic option to a premium tier with a £120 annual fee, which unlocks SIPPs and lower foreign exchange fees (from 0.99% to 0.39%). For small portfolios—say, £1,000 to £20,000—this platform’s indicative fees are £0, making it a no-brainer for cost-conscious traders.
- No trading fees on UK and US shares.
- Access to fractional shares for US stocks.
- Platform fees vary by plan, starting at £0.
Best for High-Value Portfolios
For those with larger portfolios, a flat-fee structure can save you a fortune compared to percentage-based fees. One platform, with over 450,000 users, is a standout for high-net-worth investors. It offers a staggering 40,000 investment options, including shares across the UK, Europe, North America, and Asia Pacific, plus 3,000 funds and 1,000 ETFs. Owned by a major fund manager, it’s a robust choice for those who want variety without the hefty price tag.
Here’s why I love this one for bigger portfolios: its flat-fee model keeps costs predictable. Whether your portfolio is £10,000 or £100,000, you’re paying the same £4.99 to £19.99 monthly fee, depending on your plan. Trading fees are reasonable—£3.99 for UK and US shares, £9.99 for other international markets. The downside? A 1.5% foreign exchange fee can sting if you’re trading overseas stocks frequently. Still, for frequent traders or those with six-figure portfolios, this platform’s cost-effectiveness is hard to beat.
| Portfolio Size | Indicative Annual Fee |
| £1,000 | £156 |
| £10,000 | £156 |
| £20,000 | £156 |
Best for Customer Service
Customer service can make or break your experience, especially when markets get choppy, and you need quick answers. One FTSE 250 platform, serving over 590,000 clients, nails this with its blend of high customer satisfaction and a solid investment lineup. It offers access to 16,000 shares across 24 markets, 4,600 funds, and 370 investment trusts—second only to the platform above in terms of variety.
Trading fees here are mid-range: £5 per trade for shares (dropping to £3.50 for frequent traders) and £1.50 for funds. The platform fee is 0.25%, capped at £3.50 monthly, which keeps costs manageable for smaller portfolios. The foreign exchange fee, at 0.75% for sums under £10,000, is also reasonable. In my experience, what sets this platform apart is its reliability—when you’re stuck, their support team is quick to respond, which is a lifesaver for new investors.

Best for Professional Traders
Seasoned traders need more than just low fees—they want tools that give them an edge. Enter a FTSE 250 platform with over 300,000 global clients, known for its advanced trading tools and global reach. It offers 11,000 shares across the UK, US, Europe, Asia, and Australia, plus 2,000 ETFs. While it doesn’t support actively managed funds or fractional shares, it’s a powerhouse for experienced investors who thrive on leveraged products and third-party platforms like MetaTrader4.
No trading fees on UK, US, European, or Australian shares? That’s a dream for active traders. The catch is a £96 annual platform fee if you make fewer than three trades per quarter, but this is waived if you hold £15,000 in their managed portfolio. The foreign exchange fee is a competitive 0.7%. For pros, the robust charting tools and API trading options make this platform feel like a cockpit for navigating global markets.
- Zero trading fees on major markets.
- Advanced tools for technical analysis.
- Platform fee waived for active traders.
Best for US Shares
If you’re keen on investing in US giants like Apple or Tesla, one platform owned by a wealth management firm is a strong contender. With over 50,000 clients, it offers 1,200 UK and US shares, 1,700 funds, 500 ETFs, and 230 investment trusts. The standout feature? Free trading on US shares, paired with a lower platform fee of 0.2% for US stocks (compared to 0.4% for UK shares).
Trading UK shares costs £4.95, and the foreign exchange fee is 0.95%. While it doesn’t offer fractional shares, the low fees on US stocks make it a go-to for investors eyeing American markets. I’ve found this platform particularly appealing for those building a transatlantic portfolio, as the cost savings on US trades add up quickly.
| Portfolio Size | Indicative Annual Fee |
| £1,000 | £62 |
| £10,000 | £89 |
| £20,000 | £119 |
How to Choose Your Platform
With so many options, picking the right platform feels like choosing a partner—you need compatibility. Are you a beginner looking for simplicity, or a high-roller chasing low fees on a massive portfolio? Maybe you’re somewhere in between, prioritizing customer service or niche markets like US shares. Here’s a quick guide to help you decide:
- Assess Your Budget: Smaller portfolios benefit from zero-fee platforms, while larger ones thrive with flat-fee models.
- Know Your Trading Style: Frequent traders need low per-trade costs, while long-term investors can prioritize platform fees.
- Check Investment Options: Ensure the platform offers the markets and products (like ETFs or SIPPs) you want.
- Test the User Experience: A clunky app can make investing a chore, so try the demo if available.
One thing I’ve learned from years of dabbling in markets: don’t underestimate the power of a platform that feels right. A good app should make you excited to check your portfolio, not dread it. And while fees matter, don’t skimp on tools or support if they align with your goals.
The Hidden Costs of Trading
Beyond platform and trading fees, there are other costs to watch out for. Foreign exchange fees can sneak up on you when trading international stocks, ranging from 0.39% to 1.5% depending on the platform. Then there’s the bid-ask spread—the difference between what you pay to buy a stock and what you’d get selling it. Over time, these hidden costs can erode your returns, especially if you’re an active trader.
“It’s not just about the fees you see—it’s the ones you don’t that can hurt the most.”

Another factor? Inactivity fees. Some platforms charge if you don’t trade regularly, which can catch buy-and-hold investors off guard. Always read the fine print before signing up. A platform that looks cheap upfront might not be so friendly to your wallet in the long run.
What’s Next for UK Trading Platforms?
The world of trading platforms is evolving faster than a trending stock on a bull run. App-based challengers are shaking up the old guard, offering sleek interfaces and low-to-no fees. But traditional platforms aren’t going down without a fight, rolling out better tools and competitive pricing. In 2025, expect more platforms to integrate AI-driven insights and personalized portfolio recommendations, making investing feel less like guesswork and more like strategy.
Perhaps the most exciting trend is the rise of fractional shares, letting you buy a slice of expensive stocks like Amazon without breaking the bank. Not every platform offers this yet, but it’s a game-changer for younger investors or those with smaller budgets. The future looks bright, but it’s up to you to stay informed and pick a platform that grows with you.
Choosing a trading platform isn’t just about numbers—it’s about finding a tool that fits your financial dreams. Whether you’re chasing low fees, a massive investment selection, or top-notch support, there’s a platform out there for you. Take your time, weigh your options, and don’t be afraid to start small. After all, as any seasoned investor will tell you, the best time to start building wealth was yesterday. The second-best time? Right now.
