A SIPP, self-invested personal pension, is a do-it-yourself pension wrapper that lets you choose and manage your own investments, with the same tax relief as any pension. It offers far more choice than a standard personal pension, but you take on responsibility for the decisions.
The short answer
- A SIPP is a pension wrapper that lets you choose and manage your own investments.
- It carries the same tax relief and £60,000 annual allowance as any pension.
- Low-cost platform SIPPs suit most people; full SIPPs suit larger, complex pots.
A SIPP is not a special type of investment: it is a pension wrapper, a tax-privileged container that holds investments you select yourself. The “self-invested” part is the whole point: instead of being limited to a short menu of funds chosen by an insurer, you can build and run your own portfolio, while still receiving the generous tax relief that makes pensions so effective.
How a SIPP works
Contributions receive tax relief just like any pension. Pay in £80 and the provider reclaims £20 basic-rate relief, making it £100 in your pot; higher and additional-rate taxpayers claim more through their tax return, as our guide to pension tax relief explains. Investments grow free of UK income and capital gains tax, and from 55 (57 from 2028) you can take up to 25% tax-free with the rest taxed as income. Inside the wrapper you can typically hold funds, investment trusts, exchange-traded funds, individual shares, gilts and corporate bonds, and in a full SIPP, commercial property.
What a SIPP does not do is change the pension rules. The £60,000 annual allowance, the 100%-of-earnings cap, the minimum access age and the 25% tax-free limit all apply exactly as they would to a workplace pension. The difference is purely one of control: instead of your money defaulting into a provider’s standard fund, you decide the mix of assets and how they are managed. That freedom is why SIPPs have become the wrapper of choice for people who want to consolidate scattered pots into a single, self-directed plan and take charge of the investment strategy.
SIPP versus a standard personal pension
| Feature | SIPP | Standard personal pension |
|---|---|---|
| Investment choice | Very wide, shares, ETFs, trusts, property | Limited fund range set by the provider |
| Who decides | You (or your adviser) | Largely the provider |
| Typical cost | Platform fee plus fund charges | Single bundled charge |
| Best for | Confident or advised investors | Hands-off savers wanting simplicity |
Who a SIPP suits, and who it does not
There are broadly two flavours. Low-cost “platform” SIPPs from the big investment platforms suit most people, offering thousands of funds and shares for a modest percentage or flat fee. Full SIPPs, which allow more exotic holdings such as commercial property, carry higher charges and only make sense for larger, more complex pots. The wider trade-offs are covered in our guide to SIPPs explained. A business owner, for example, might use a full SIPP to hold their trading premises, paying rent into their own pension, powerful, but not something to arrange without specialist input.
Charges deserve particular attention because they compound. On a percentage-fee platform, a large pot can rack up meaningful annual costs, whereas a flat-fee provider may work out cheaper once the balance passes a certain size; for a small pot the reverse is often true. Add fund charges of perhaps 0.1% for a tracker or nearer 0.75% for an active fund, and the total you pay each year can vary widely. Over 20 or 30 years, a difference of half a percent a year can cost tens of thousands of pounds, so the cheapest wrapper is not always the one with the lowest headline platform fee, but the combination that best fits your balance and how often you trade.
- 1
Check the charges
Compare the platform fee, dealing costs and underlying fund charges, small percentages compound heavily over decades.
- 2
Match it to your confidence
A SIPP hands you the decisions. If you would not choose your own funds, a simpler pension may serve you better.
- 3
Watch what you give up
Never transfer an old pension into a SIPP without checking for guarantees, exit penalties or valuable safeguarded benefits.
- 4
Consider consolidation carefully
A SIPP can bring scattered pots together, but weigh the pros and cons first.
The same tax relief, more control
A SIPP gives you the full pension tax break, up to £60,000 a year with relief at your marginal rate, while letting you decide exactly how the money is invested. The freedom is the benefit; the responsibility is the price.
A SIPP rewards engagement. If you enjoy managing investments, or work with an adviser, it offers flexibility a standard pension cannot match. If you would rather not make those calls, that is fine too: the important thing is an honest view of your own appetite. Many people use a SIPP with a single diversified multi-asset fund, getting the low cost and consolidation benefits without having to pick individual shares; others build detailed portfolios. Both are valid ways to use the wrapper. This is information, not personal advice, and investments can fall as well as rise.
