InvestEngine Fees Explained: What You Really Pay (2026)
InvestEngine offers genuinely free DIY ETF investing in a UK ISA or SIPP. Every InvestEngine fee in plain English: the £0 DIY platform fee, the optional 0.25% managed service, FX and fund costs, from an ex-brokerage insider.

InvestEngine is one of the cheapest ways in the UK to run an ETF portfolio: £0 platform fee for do-it-yourself investing, in an ISA, SIPP or general account. The catch is not a hidden fee, it is a scope limit: InvestEngine is ETF-only. Here is exactly what you pay.
For the principles behind each cost, start with broker fees explained.

Free DIY investing
For do-it-yourself portfolios, InvestEngine charges no platform fee and no dealing commission, across its ISA, SIPP and general accounts. It removed its remaining 0.15% SIPP fee at the end of 2024, so a DIY SIPP is now free of platform charges too. Transfers in and withdrawals are also free. For a buy-and-hold ETF investor, that is about as low as platform cost goes in the UK.
The optional managed service (0.25%)
If you would rather not pick your own ETFs, InvestEngine’s Managed portfolios cost 0.25% a year for construction, monitoring and rebalancing. That is entirely optional: choose DIY and you pay the platform nothing. The managed fee buys convenience, not better returns, so it is worth being clear about which you actually want.
No FX fee
Because every ETF on InvestEngine is denominated in pounds, there is no currency-conversion fee to worry about: one less cost than you face on brokers that route you into dollar or euro lines. See FX fees explained for why that matters elsewhere.
The fund’s own cost (TER)
The main ongoing charge you pay is the ETF’s own TER, not InvestEngine’s. On DIY portfolios this can start from around 0.03% a year for broad index funds. You pay this on any platform, so it is not unique to InvestEngine, but it is the number that really drives your long-term cost. The fee calculator shows why.
”If DIY is free, how does InvestEngine make money?”
Openly: through the 0.25% managed service, interest, and its business and partnership lines. A platform earning a fair, disclosed margin elsewhere is normal; the point is that the DIY cost to you really is £0.
Who it suits, and who might want more
InvestEngine fits anyone who wants a low-cost, ETF-only ISA or SIPP, DIY or managed, and beginners who like the simplicity. It will not suit you if you want individual shares, investment trusts or non-ETF funds, since it does not offer them. That scope limit is the real trade-off, not the price.
