Hargreaves Lansdown vs Interactive Investor SIPP: My 2026 Comparison

Hargreaves Lansdown offers established support and strong research, while Interactive Investor's subscription becomes proportionately smaller as the pension grows.

The annual fee difference is £36.88 in Hargreaves Lansdown's favour at £10,000, £278.12 in Interactive Investor's favour at £100,000, and £695.12 in its favour at £250,000. Hargreaves Lansdown's research and support justify the extra cost only when an investor will use those services enough to outweigh the fee difference.
