Interactive Investor SIPP Review 2026

Interactive Investor shows why annual pounds matter more than headline percentages. Its £179.88 Plus subscription equals 0.072% of a £250,000 pot before investment and transaction costs.

The £100,000 boundary is an important cost threshold. The annual subscription rises from £71.88 on Core to £179.88 on Plus, so a transfer just above that level needs careful costing.

At £250,000, the fund model gives £625 at AJ Bell, £875 at Hargreaves Lansdown and £179.88 at Interactive Investor. Flat pricing wins decisively at that balance.

The subscription includes mainstream investment choice, dealing tools and drawdown.

Percentage-fee providers can offer better value for smaller pensions. For a large self-directed pot, Interactive Investor is my leading fee benchmark and a credible long-term home.
