Verdict
Investors with portfolios above about £20,000, where the flat Core fee of £71.88/yr beats HL's 0.35%. Excellent value from £50,000, where HL charges £175/yr or more. Portfolios over £100,000 need the Plus plan (£179.88/yr), which is still far cheaper than percentage fees at that size.
Active traders and ETF investors who want zero fees and a flexible ISA (so you can withdraw and re-invest within the same tax year). Note there is no SIPP, so not suitable as a standalone pension platform.
