Important information: The ii SIPP is for people who want to make their own decisions when investing for retirement. As investment values can go down as well as up, you may end up with a retirement fund that’s worth less than what you invested. Usually, you won’t be able to withdraw your money until age 55 (57 from 2028). If you’re unsure if a SIPP is right for you, please speak to an authorised financial adviser. Tax treatment depends on your individual circumstances and may be subject to change in the future.

“With a lot of providers’ charges, it’s this plus that plus that. Whereas with ii, it’s straightforward. What I pay is what I pay – ii’s fees are just so much cheaper. That’s why I’m with ii.”
Mark, 47, was frustrated with the fees he was paying with his old provider. With ii’s low flat fee, he now gets to retire earlier.

Other providers usually charge a percentage of your pot. That means the more your pension grows, the more they’ll take. The ii SIPP is different. With our simple flat fee, you can keep more of what’s rightfully yours.
