UK trading platforms are used by millions of investors to gain access to global stock markets. Now new analysis has ranked the most expensive, best for customer service and most appropriate for high volume traders.
A trading platform allows the new army of DIY investors to buy and sell shares, funds, investment trusts and exchange traded funds (ETFs) directly rather than through a financial adviser or traditional stockbroker.
There are at least 10 main investment platforms in the UK – when it comes to how to invest, the trick is to find one that charges competitive trading and platform fees, offers a broad range of investments and provides good customer service.

Jo Groves, investment specialist at Kepler Partners, which has analysed and ranked the UK’s main investment platforms, said: “Over ten million DIY accounts have been opened in the UK since the pandemic, fuelling an increase in the number of trading platforms, with app-based challengers now competing with traditional providers.
“Choosing the right platform for your needs is vital but the choice can feel overwhelming. Our rankings help individual investors weigh up what matters most to them, whether that’s cost, range of investments or premium customer service.”
We look at the best investment platforms for beginners in a separate article.
How much do investment platforms charge?
Fees and investment costs are often the most important consideration for investors. While a few percentage points of difference in fees may seem insignificant, they can add up to thousands of pounds over time and significantly erode the value of portfolios.
For example, £50,000 growing at 10% a year would be worth around £336,000 after 20 years with a zero-platform fee provider. But a platform charging 0.45% a year would result in almost £30,000 less, purely due to fees eroding returns over time, according to Kepler’s calculations.
