Verdict
Investors who want full platform breadth at lower cost than Hargreaves Lansdown. The £42/yr ISA cap on ETFs and shares makes it especially competitive for portfolios above £17,000 investing in ETFs or stocks.
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.
