How to choose the right SIPP.

The right SIPP depends on how you want to invest, how big your pension pot is, and how much control you want over decisions.

Choose Vanguard if: You want the cheapest possible long-term pension and you’re happy holding only Vanguard’s own funds.

Choose Interactive Investor if: You have a pension pot above £100,000 and want a flat fee that doesn’t scale with the size of your investments.

Choose AJ Bell if: You want a sensible balance between cost, control and investment choice, with strong customer service and a £120 cap on shares.

Choose Hargreaves Lansdown if: You value the best research, customer support and education, and don’t mind paying a premium for it.

Choose PensionBee or Moneybox if: You want simplicity, app-first design, and zero hassle, with someone else picking the investments for you.

Choose Nutmeg if: You want a fully managed portfolio without the hands-off feel of a workplace pension.

Choose Bestinvest if: You want DIY investing with optional human coaching from a qualified adviser.

Choose Standard Life if: You’re consolidating an old workplace pension and want to stay with a familiar provider.
