Self-Invested Personal Pension’s (SIPP) are specifically designed for people who reside outside the UK but have contributed to a UK pension/s and wish to manage their own fund and investments.
Essentially, a SIPP is a pension “wrapper” that holds investments until you retire and start to draw a retirement income. It’s a type of personal pension and works in a similar way to a standard personal pension, with the main difference being that you have more flexibility over the investments chosen.
