How to Invest in US Stocks from the UK Without High Fees
UK investors can access US stocks cheaply and efficiently. Here's how to do it without overpaying on fees or currency conversion.
Why UK Investors Want US Exposure
The US stock market accounts for roughly 65 per cent of global market capitalisation and has delivered outstanding long-term returns. Companies like Apple, Microsoft, Nvidia, Amazon, Alphabet, and Meta have transformed industries and generated extraordinary shareholder returns. For UK investors, getting cost-effective access to US stocks is a priority — and it is more straightforward than many realise.
The Cheapest Route: US Index ETFs
The simplest way to invest in US stocks from the UK is through a low-cost ETF tracking the S&P 500 or total US market. The Vanguard S&P 500 ETF accumulating (VUAG) charges just 0.07 per cent per year and is available on most UK platforms. The iShares Core S&P 500 ETF (CSPX) matches this cost. Both trade in pounds on the London Stock Exchange, so no currency conversion is needed at the point of purchase.
Currency Risk and Sterling
When you buy a US stock ETF, the underlying holdings are in US dollars. If the pound strengthens against the dollar, your sterling returns will be reduced even if the US market rises. Over long periods, currency movements tend to even out, and hedging costs money — most long-term investors simply accept the currency exposure as part of a globally diversified portfolio.
Individual US Stocks
If you want to invest in individual US companies — Apple, Tesla, Nvidia — most UK platforms allow this, though with a currency conversion charge. Hargreaves Lansdown, AJ Bell, and Trading 212 all allow you to buy shares listed on US exchanges. Trading 212 charges a 0.15 per cent FX fee on US stock purchases, which is among the lowest available. Freetrade charges 0.99 per cent FX fee, and Hargreaves Lansdown charges 1.0 per cent. For frequent US stock traders, the FX fee adds up significantly — ETFs priced in pounds avoid this cost entirely.
Withholding Tax on US Dividends
US companies pay dividends subject to a 15 per cent US withholding tax for UK investors (reduced from 30 per cent under the UK-US double tax treaty). This withholding tax cannot be reclaimed within an ISA. When investing in a US ETF, the ETF itself often suffers this withholding tax at the fund level before distributions reach you. For growth-oriented investors in accumulating ETFs within an ISA, this has minimal impact since dividends are automatically reinvested and the tax drag is modest relative to the long-term return. For income investors relying on US dividends, it is worth factoring into yield calculations.

InvestEngine: zero platform fee, zero dealing fee, accumulating US ETFs available — best for low-cost passive US exposure. Trading 212: zero dealing fee, 0.15 per cent FX for individual US stocks, ISA available — best for those wanting individual stocks alongside ETFs.

Hargreaves Lansdown: widest selection of US stocks and funds but highest fees — best for investors who also want UK stocks and investment trusts in the same account.
Practical Recommendation
For most UK investors seeking US equity exposure, the Vanguard S&P 500 accumulating ETF (VUAG) or iShares Core S&P 500 (CSPX) within a Stocks and Shares ISA on InvestEngine or Vanguard UK provides the cheapest, simplest, and most tax-efficient solution. For those who also want individual US stocks, Trading 212's low FX fee makes it one of the better options for occasional stock purchases alongside an ETF core portfolio.
