Verdict
Fund investors with portfolios above £27,500 where the flat Core fee of £71.88/yr beats percentage-based rivals. Excellent value above £50,000 where HL would charge £175/yr and above. Upgrade to Plus (£179.88/yr) needed for portfolios over £100,000.
Passive investors who want to build a low-cost ETF portfolio and never pay a platform fee. Ideal if you're happy with index funds and ETFs and don't need access to active funds or individual shares.
