Our verdict
Interactive Investor offers the most investment options in the UK SIPP markets. With II you can invest more than 40,000 domestic and international shares, ETFs, bonds and over 3,000 funds (AJ Bell has 2,000 and HL offers 2,500 funds).
Is Interactive Investors' SIPP (pension) any good?
Yes, interactive investor won "Best SIPP Provider" in the 2025 Good Money Guide Awards. ii has a really good pre-selected fund section, which makes crucial SIPP asset allocation decisions much easier. It's very low cost too, with excellent education and research, and a huge range of investments to choose from.
The key advantage of interactive investor’s SIPP is that it has a flat-fee structure. This means that annual account charges do not increase as your pension pot grows in size. This structure can help those with larger SIPP portfolios save on fees, however it can be a little expensive for small pensions if you are just starting to invest for your retirement.
For smaller pension pots, those that just want to invest in ETFs, InvestEngine offer a free SIPP, but it is limited to just UK-listed ETFs, so you can't buy individual shares. One of the good things about ii's SIPP is that you can buy bonds, gilts, and shares in small and large UK and international companies.
Even though ii charges £3.99 for buying funds. If you compare this to Hargreaves Lansdown, which does not charge for buying and selling funds, but HL SIPP fees are higher. If you have £100,000 in your SIPP with ii you'd pay £71.88 a year, versus HL where your fees would be £450.
So, if you have a big pension, is it worth moving it to ii? Well, yes at the moment, as interactive investor claim their SIPP pricing can give you an additional £68,467 towards your pension after 30 years compared to HL. Plus, if you transfer your SIPP to ii before 31st August, you can claim up to £2,000 in cash back.

Of course, you’ll need to add cash or start a transfer of a minimum value of £10,000 to qualify for your cashback reward. Terms apply.
