A Complete Guide to Self-Invested Personal Pensions in the UK

Planning for retirement is one of the most important financial decisions you’ll ever make. In the UK, one popular option for long-term retirement saving is a SIPP. But what exactly is a SIPP, how does it work, and is it right for you?

In this guide, we’ll explain everything you need to know about SIPPs in a clear and practical way.

1. What Is a SIPP?

A SIPP (Self-Invested Personal Pension) is a type of UK personal pension that gives you more control over how your retirement savings are invested.

Unlike standard workplace or personal pensions—where the provider chooses a limited set of investments—a SIPP allows you to choose and manage your own investments, either on your own or with professional advice.

Key definition:

A SIPP is a tax-efficient pension that lets you invest in a wide range of assets to build your retirement fund.

2. How Does a SIPP Work?

A SIPP works in a similar way to other pensions, but with greater flexibility.

Step-by-step overview:

1. You pay money into your SIPP
2. Contributions can be regular or one-off lump sums.
3. The government adds tax relief
4. For basic-rate taxpayers, every £80 you contribute becomes £100.
5. Higher-rate taxpayers may be able to reclaim extra tax relief.
6. You invest the money
7. You choose how your pension is invested (shares, funds, ETFs, etc.).
8. Your investments grow tax-free
9. No Income Tax or Capital Gains Tax inside the SIPP.
10. You access your pension at retirement
11. Usually from age 55 (rising to 57):
12. Up to 25% tax-free
