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. Tax treatment depends on your individual circumstances and may be subject to change in the future. If you’re unsure about opening a SIPP or transferring your pension(s), please speak to an authorised financial adviser.

Important information: It’s important to take your time before transferring your pension. Make sure to consider what the best option is for you. Don’t transfer just to qualify for the offer, and don't rush any decision to meet the offer deadline. We periodically run offers, and there will likely be other opportunities in the future.

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.

What is the ii Personal Pension?

The ii Personal Pension gives you the same tax benefits as other personal pensions, but with more control. You have the freedom to invest your retirement savings your way, while keeping costs low.

Many other SIPP providers charge a percentage fee. So the more your investments grow, the more you pay.

But with ii, it's different. With our low, flat monthly fee, you can keep more of what's rightfully yours.
