InvestEngine
InvestEngine is the most disruptive entrant in the UK SIPP market — a genuine 0% platform fee on both managed and DIY portfolios. The catch: you can only hold ETFs, not traditional funds or individual shares. For most passive investors this is no limitation (ETFs from Vanguard, iShares, SPDR etc. cover every major asset class). InvestEngine makes money from the spread on ETF trades and from its managed portfolio service. The platform is app-first and clean. For cost-conscious investors who are happy with ETFs, InvestEngine is objectively the cheapest SIPP in the UK. The risk is platform longevity — it's a younger company than the established players — but assets are held by a regulated custodian and covered by FSCS up to £85,000.
