The table above compares the fees of platforms with a comparable investment solution to InvestEngine DIY, assuming a £0 starting ISA portfolio, investing £1,666.67 into five UK ETFs per month for 10 and 20 years with 7% growth per annum. Fees as displayed on platform websites as at 02 February 2026. The displayed fees only include the costs charged by the respective platforms. They do not include any product fees such as ETF charges and assumes no changes to the ISA allowance. Some platforms may have reduced fees depending on different volumes, funding sizes or subject to additional subscriptions. The information above is for illustrative purposes only and does not constitute personal advice or a recommendation to switch provider. Where pricing depends on usage (such as trade frequency, asset type or use of regular investing features), standardised assumptions have been applied. If these features are not used, actual costs may be higher. Tiered pricing has been applied based on the portfolio values shown. Actual costs will vary depending on individual circumstances and investment behaviour. Providers may change pricing at any time. For up to date fees you should visit their respective websites.

¹Vanguard: Subscription fee is based on the monthly 0.15% charge on the value of shares held in the ISA, capped at £31.50/mo. Accounts under £32,000 will be subject to a £4 p/m charge instead.
²AJ Bell: Subscription fee is based on the monthly 0.25% charge on the value of shares held in the ISA, capped at £3.50/mo.
³Interactive Investor’: Free Regular Investing removes the £3.99 dealing fee for eligible UK investments. As this feature forms part of II’s standard pricing and is marketed as covering a wide selection of UK investments, we assume regular investing is used for eligible mainstream UK ETFs and model execution costs at £0. The £14.99 monthly platform fee (accounts over £100k) is applied in full and is not offset by the included free trade, which is redundant where regular investing is used. For absolute clarity on eligibility, customers may wish to confirm directly with Interactive Investor.
⁴Fidelity: Takes into consideration a reduction in trading fee from £5 to £1.50 as a result of regular investing being enabled.
⁵Hargreaves Lansdown: capped at £12.50 p/m. Certain ETFs are able to be traded free of charge with a regular investing enabled.
