Verdict
InvestEngine is the cheapest platform for UK investors who exclusively want ETFs in an ISA. Zero platform fee, zero commission, and 0.25% FX on non-GBP ETF share classes. By using GBP-denominated ETF share classes (VUSA/GBP, CSPX/GBP), you can eliminate FX costs entirely. The limitation: ETF-only, no individual stocks.
