Verdict
Fund investors who want a broad range of active and passive funds with no dealing charge. Fidelity's 0.35% rate is cheaper than HL for funds, and it offers a junior ISA for families.
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.
