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.

Keep more of what you make
With most other investment platforms, you’ll pay a percentage fee of your assets. That means the more your pot grows, the more they take. What’s more, it’s not always clear how much a percentage fee will cost you in pounds and pence.
On our standard plans, your monthly fee stays flat as your investments grow. Whether your pot is £50,000 or £500,000, you have the same fee. And what you save now compounds. The money you save today grows and grows tomorrow. That means more money for your future.

Why Allison transferred to ii
“The dream is to build up my pension pot to a point where I can retire comfortably at 57.
I'd previously been doing this with a Hargreaves Lansdown SIPP, but after 5 years I made the decision to find a new SIPP provider with a more personal touch and lower charges.”

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.
