SIPP or standard personal pension: how they differ

A SIPP and a standard personal pension are both personal pensions: defined contribution schemes you arrange yourself, rather than through an employer. The difference is what you do inside them. A SIPP (self-invested personal pension) lets you hold multiple investments and products and manage the pension fund yourself, choosing from a range of thousands of shares, exchange-traded funds and mutual funds¹. A standard personal pension usually puts your money into a ready-made fund chosen by the provider.

Both come with the same tax treatment. Contributions are topped up with tax relief, subject to the Annual Allowance, and investments grow free from income tax and capital gains tax³. You can open and contribute to a SIPP between age 18 and 75, and you can have as many SIPPs as you want⁵.

The trade-off is control against cost and risk. SIPPs are considered riskier than most personal pension schemes, and were created to allow experienced investors the opportunity to take more risks². There is also no cap on SIPP fees, unlike workplace pension schemes, which are allowed to charge a maximum of 0.75%³. Close to one million (960,000) pension savers in 2024 decided to take more control over their nest egg by opening a self-invested personal pension³.

What each one offers

A personal pension is one you take out yourself, for example if you are self-employed¹⁰. You choose the provider and decide how your contributions will be paid, sometimes through an independent financial adviser¹¹. Personal pensions are provided by insurance companies, often through banks and building societies, and sometimes through your workplace¹². They are a form of defined contribution or money purchase pension, and all personal pensions are defined contribution schemes¹³.

Within that, there are two types: stakeholder pensions and self-invested personal pensions¹⁴. A SIPP is a personal pension, and although your employer may contribute to it, it is very much your pot which you pay into¹⁵. What marks it out is the investment range. SIPPs allow you to hold multiple investments and products, so you can manage your pension fund yourself and have more control². That range covers thousands of shares, exchange-traded funds and mutual funds¹⁶.

There are limits on what a SIPP can hold. To be eligible for investment in a SIPP, bonds generally need to be listed on a recognised stock exchange, such as the London Stock Exchange⁸. You cannot hold savings products like fixed-rate bonds that you see promoted in your local bank or building society⁸. A standard personal pension avoids these decisions entirely: the provider's fund managers choose and rebalance the investments for you.

Fees, charges and eligibility

Charges are where the two plans diverge most sharply. Personal pension providers may charge you for starting and running your pension, and usually they take a percentage from your pension fund¹⁰. A SIPP works the same way in principle, but the range of what providers charge is wider because there is no cap. Unlike workplace pension schemes, which are allowed to charge a maximum of 0.75%, there is no cap for SIPP fees³.

How the fee is structured matters as much as its size. Percentage-based fees are generally cheaper for smaller pots, and flat annual fees are often more cost-effective for larger pots over £50,000¹⁶. Online SIPPs are typically low-cost¹⁵. Some providers set minimum contributions: one SIPP provider allows a regular savings plan from £20 or a lump sum from £800⁷.

The risk of getting this wrong is real. In one case the Financial Ombudsman Service looked at, a consumer complained that the charging structure in the SIPP was considerably higher than her previous stakeholder pension plan¹⁷. That is the pattern to watch: a transfer into a SIPP can raise your ongoing costs even when the investment choice improves.

Eligibility is broadly the same for both. Anyone under the age of 75 can pay into a SIPP, and you can open and pay into one if you are under 75 and a UK resident, or if you are working overseas with UK earnings⁵. A personal pension can be set up yourself through a provider, and may be set up by self-employed people¹³. Contributions should usually be made from UK relevant earnings¹³.

Tax relief on what you pay in

Tax relief works identically whichever plan you choose, so it should not decide the question. For every £80 you pay in, the government will top it up with an additional £20⁶. Higher rate taxpayers can claim a further 20% tax relief through their self-assessment tax return, and additional rate taxpayers an extra 25%⁶. Put another way, it costs higher rate taxpayers £60 to put £100 in a pension, and £55 for additional rate taxpayers⁵.

There is a ceiling. You can contribute and get tax relief up to the Annual Allowance of £60,000, or 100% of your earnings if you earn less than that⁷. If you have little or no earnings, you can still pay in up to £2,880 each tax year, and HMRC will add basic-rate tax relief of 20% so you could have up to £3,600 in total⁷. Your employer can make contributions to your SIPP pension, either as regular or one-off payments¹⁸.

When you take money out, the treatment is the same for both. Up to 25% of your SIPP fund can be taken tax-free, subject to a maximum of £268,275³. Typically, 25% of the withdrawal can be taken as a tax-free lump sum, while the remaining 75% is taxed as income according to your tax band¹⁸. The maximum tax-free lump sum you can usually take is currently £268,275, unless you have allowance protections in place⁵.

One further point that applies to SIPPs specifically: currently, pensions will not be included in your estate when you die, meaning that no inheritance tax will be payable¹⁹. A SIPP is held within a trust wrapper, so it will still be administered separately from your will²⁰. That makes the expression of wish form, which tells your provider who you would like to receive your pension, worth keeping up to date¹.

Opening an account or switching

Opening a SIPP follows three steps: choose a provider; complete an application to open an account, usually online; and pay into your account, using a lump sum, regular contributions, or a transfer from a previous pension²¹. A personal pension is arranged the same way in outline, though you may do it through an independent financial adviser¹¹.

Switching between the two is straightforward in process terms. It is easy to transfer a personal pension to a SIPP if you want the additional investment choice and flexibility, or move a SIPP to a personal pension, by contacting your new pension provider². A pension transfer means moving money from one personal pension to another, or from a personal or workplace pension to a SIPP, SSAS or QROPS²².

Before transferring, check the charging structure on both sides. The ombudsman case involving Juhi turned on exactly this: she was recommended to transfer her existing pension into a new self-invested personal pension, and the charging structure in the SIPP was considerably higher than her previous stakeholder pension plan¹⁷. A separate case concerned a consumer who complained about the length of time it took her adviser to inform her its pension transfer specialist had decided no longer to advise on the transfer of her British Steel Pension Scheme to a SIPP²³.

If a transfer is delayed, there is a route to complain. The Financial Ombudsman Service publishes case studies on consumers who complain about a delay in transferring a pension fund¹⁷. It also handles complaints about transfers from personal pension arrangements²².

Service and complaints

Complaints about personal pensions are common enough to be worth knowing about before you choose. In the first quarter of 2026/27, the Financial Ombudsman Service opened 931 complaints about personal pensions²⁴. In 2025/26, 49% of personal pension complaints were upheld²⁵.

SIPPs have their own history in the complaints data. In 2020/21, the most complained-about product was self-invested personal pensions, with 3,021 new complaints²⁶. A decade earlier, SIPPs accounted for 2% of investment and pension complaints²⁷. The pattern shows that the extra control a SIPP gives you also generates more disputes, often about the advice that led to the transfer rather than the product itself.

Two ombudsman cases illustrate the kinds of problems that arise. In one, a consumer complained about advice to switch to a different pension plan that was later used to invest in an unregulated collective investment scheme, which was unsuitable²⁸. In another, Mario was recommended to change his personal pension plan to a self-invested personal pension²⁸. These are the risks that come with the wider investment range: a SIPP can hold investments a standard personal pension cannot, and not all of them will be suitable.

If you think you have been mis-sold a financial product, there is a process to follow, and providers are required to give you key information about their charges, which you can complain about if they do not²⁹. The complaint process is separate and different from any appeals process, so it is worth checking which one applies to your situation³⁰.

Protection for your money

The money in your SIPP or personal pension is held separately from the provider's own funds. The providers of SIPPs have their investors' funds held separately, so the money is safe if they were to go out of business³¹. That separation is the first layer of protection, and it applies whether you hold a SIPP or a standard plan.

The second layer is different for the two plan types. Self-invested personal pensions are classed as uninsured pension schemes, as opposed to contracts of long-term insurance³¹. That distinction matters if a provider fails, because the compensation arrangements that apply to insurance-based personal pensions are not the same as those for SIPPs.

If something goes wrong and you cannot resolve it with the provider, the Financial Ombudsman Service can look at complaints about personal pensions¹¹. It also handles complaints about transfers from personal pension arrangements²². The service is free to consumers.

There is also free, impartial guidance available. Pension Wise offers guidance on your pension options, and providers are expected to point you towards it⁹. For general help understanding pensions, the MoneyHelper service and organisations such as Citizens Advice can explain your options¹. In Northern Ireland, nidirect provides guidance on understanding personal pensions and on getting information and help with pensions¹⁰.

Where protection stops is worth being clear about. There is no cap on SIPP fees, so a poorly chosen SIPP can erode your fund in a way a workplace scheme's 0.75% cap would prevent³. And the investment risk sits with you: a SIPP lets you choose your own investments, and their value can fall as well as rise.
