Interactive Investor charges a flat monthly subscription instead of a percentage. On a £200,000 portfolio, £5.99 a month is a fraction of what percentage-fee platforms charge, which is why ii keeps winning larger DIY investors.
The equation flips for small pots: £71.88 a year on £10,000 is 0.7%, more than almost any rival. Work out your portfolio size first, then decide.
J.P. Morgan Personal Investing is what Nutmeg became. J.P. Morgan bought Nutmeg in 2021 and retired the Nutmeg brand on 3 November 2025. The service works the same way: you choose an investment style, and the portfolio is built and managed for you. It offers a Stocks & Shares ISA, Lifetime ISA, Junior ISA, personal pension (SIPP) and general investment account.
You pay one service fee instead of dealing charges: 0.75% a year on the first £100,000 in the managed styles and 0.35% above that, or 0.45% then 0.25% for Fixed Allocation. On £20,000 that is £150 a year before fund costs. The trade-off is cost against effort: you pay more than a self-directed platform's fee, and in return the portfolio is chosen and rebalanced for you.
It depends on what you hold and how often you trade. Interactive Investor's platform fee is core £5.99/month (up to £100k); Plus £14.99/month (no limit); Premium £39.99/month, against managed styles: 0.75% a year on the first £100k, 0.35% above. Fixed Allocation: 0.45%, then 0.25%. Inc. VAT; fund costs extra at J.P. Morgan Personal Investing. On dealing, Interactive Investor charges £3.99 per trade (£2.99 on Premium) for shares and £3.99 per trade (£2.99 on Premium) for funds, while J.P. Morgan Personal Investing charges no dealing charges (managed service) for shares and no trading charges; underlying ETF costs and market spread apply for funds. Fees verified July 2026.
