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). Before transferring your pension, check if you’ll be charged any exit fees and make sure you don't lose any valuable benefits such as guaranteed annuity rates, lower protected pension age or matching employer contributions. If you’re unsure about opening a SIPP or transferring your pension(s), please speak to an authorised financial adviser.

Choosing the right SIPP provider could mean thousands more pounds for your retirement. Dig deeper into how the ii SIPP compares to some of the others on the market.

"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 take. The ii SIPP is different. Bring all of your investments under one roof with our simple flat fee and save more for your retirement.
