Comparing investment platforms isn't just about who charges the lowest headline fee — most UK platforms price differently depending on whether you hold funds, ETFs or shares, and whether you're investing £5,000 or £250,000. A platform that's cheapest for a small ETF portfolio can easily be the most expensive once you're holding funds at scale. Pick any two platforms below for a side-by-side breakdown, including the exact portfolio size at which one becomes cheaper than the other.
