Commission-free is not cost-free

Looking for the cheapest investment app in 2026? The headline says "zero commission". Yet the foreign exchange (FX) fee on every US share quietly adds up. So we rechecked the live pricing for Lightyear, Robinhood, Trading 212, Freetrade, InvestEngine, Hargreaves Lansdown and J.P. Morgan. Then we worked out the real cost of buying a US share on each.

Lightyear review UK (2026): honest pros, cons and fees

Last updated: 9 June 2026

By Stiv · Design, technology and personal finance

This is an independent opinion piece based on my own testing of the Lightyear app and current market research. Views expressed are my own and do not constitute professional or financial advice.

Cool Factor: 4/5 (Stone cold)

In this independent Lightyear review UK, I take a proper look at one of the most talked-about investing apps in Britain right now. Lightyear has spent the past year cutting costs hard, so UK personal accounts now get free share and ETF dealing and a flat 0.1% FX fee. As a result, it sits firmly among the cheapest platforms available to UK investors today.

Throughout this Lightyear review UK, I cover what Lightyear is, what you can invest in, fees, ISAs, Vaults, pros and cons, and how it compares to Freetrade, Trading 212, AJ Bell Dodl, Moneybox and Finimize. So, if you want a no-nonsense view before opening an account, read on. If you only want the sign-up offer and terms, head to our Lightyear referral page instead.
