A SIPP is a personal pension you manage yourself, not one your employer runs

A Self-Invested Personal Pension (SIPP) is a type of personal pension where you decide what to invest in, rather than leaving those choices to a pension provider or employer scheme. You open a SIPP with a provider — usually a bank, investment firm, or specialist pension company — and then you control which investments hold your pension money: stocks, bonds, funds, property, or other assets allowed under pension rules.

The key difference from other personal pensions is control. With a standard personal pension, the provider typically offers a limited menu of investment funds you can choose from. With a SIPP, you pick individual investments yourself, or you can hire a financial adviser to do it. You pay fees to the SIPP provider for holding and administering your account, separate from any investment fees.

SIPPs are only available to UK residents, and you must be under age 75 to open one (though you can keep one after 75). You can contribute up to £60,000 per tax year, or your annual earnings if they are lower — the same limit that applies to all personal pensions.

Key Takeaways

  • A SIPP lets you choose your own investments rather than picking from a provider's set menu, which means more control but also more responsibility for decisions.
  • You pay annual fees to the SIPP provider for administration, separate from any charges the investments themselves carry.
  • You can contribute up to £60,000 per tax year, and contributions receive tax relief at your marginal rate.
  • You cannot access your SIPP money until age 55 (rising to 57 from April 2028), and you must follow strict rules about how much you can withdraw each year.
  • A SIPP is most useful if you have significant savings to invest, want control over investment choices, or are self-employed without an employer pension scheme.

How contributions and tax relief work

When you pay money into a SIPP, you receive tax relief on that contribution. If you earn £50,000 and contribute £10,000 to your SIPP, you pay income tax only on £40,000 of earnings. If you are a basic-rate taxpayer (20%), the government effectively tops up your contribution by 20%, so your £10,000 becomes £12,500 in your pension pot.

Higher-rate taxpayers (40%) and additional-rate taxpayers (45%) can claim the extra relief through their tax return. For example, a 40% taxpayer who contributes £10,000 can claim back a further £6,667 through self-assessment, bringing the total pension value to £16,667.

If you are not working or have no taxable income, you can still contribute up to £3,600 per tax year and receive basic-rate tax relief automatically — the government adds 20% to your contribution. You cannot contribute more than you earn in a tax year, except for this £3,600 minimum allowance.

What you can and cannot invest in

SIPPs can hold a wide range of investments: stocks listed on recognised exchanges, bonds, investment funds, exchange-traded funds (ETFs), cash, and commercial property. You can also hold residential property in a SIPP under certain conditions — the property must be let out to tenants, you cannot live in it yourself, and there are strict rules about borrowing to buy it.

Prohibited investments include fine art, wine, classic cars, and most personal-use assets. You cannot lend money to yourself from your SIPP, and you cannot use SIPP money to buy property from a connected person (a family member or business partner, for example). These rules exist to prevent people using pensions as tax shelters for personal spending.

The SIPP provider sets the specific list of what they will hold. Some providers offer a very broad range; others restrict you to stocks and funds. Check the provider's investment menu before opening an account if you have specific assets in mind.

Fees and costs you need to know

SIPP providers charge annual administration fees, which typically range from £100 to £500 or more per year depending on the provider and the complexity of your investments. Some charge a percentage of your pension pot (often 0.3% to 0.5%), others charge a flat fee, and some use a combination. A few providers charge per transaction when you buy or sell investments.

On top of the SIPP provider's fee, you pay charges on the investments themselves — fund management fees, trading costs, and bid-ask spreads. These are separate from the SIPP administration fee and vary widely depending on what you invest in.

Because of these fees, a SIPP usually makes sense only if you have a reasonably large pension pot — typically £50,000 or more. If your pot is smaller, the annual fees eat into your returns more significantly, and a standard personal pension with lower charges may be better value.

When you can access your money

You cannot normally withdraw money from a SIPP until age 55. From April 2028, this minimum age rises to 57, and it will continue rising in line with changes to the state pension age. If you try to access your SIPP before the minimum age, you face a tax charge of up to 55% on the amount withdrawn, plus income tax on top.

Once you reach the minimum age, you can withdraw money flexibly. You can take your first 25% tax-free (this is called the tax-free lump sum), and the remaining 75% is taxed as income at your marginal rate. You do not have to take all your money at once — you can withdraw small amounts over time, or leave it invested and take nothing.

Alternatively, you can use your SIPP to buy an annuity (a may provide income for life) or set up a drawdown arrangement where the provider pays you regular income from your pot. The rules and tax treatment differ for each option.

SIPP versus workplace pensions and standard personal pensions

If your employer offers a workplace pension, contributions are usually deducted from your salary before tax, which is simpler than claiming tax relief yourself. Your employer may also contribute to the scheme. Workplace pensions typically have lower fees than SIPPs because the costs are spread across many members.

A standard personal pension (sometimes called a stakeholder pension) is simpler to manage than a SIPP — you choose from the provider's investment options rather than picking individual investments — but you have less control. Standard personal pensions usually charge lower fees than SIPPs, making them better value if your pot is small.

A SIPP is most useful if you are self-employed, have stopped working but have savings to invest, or want detailed control over where your pension money goes. If you have a workplace pension, you can also open a SIPP and contribute to both — there is no rule against it, though your total contributions across all pensions cannot exceed £60,000 per year.

How to open a SIPP and what to expect

To open a SIPP, you choose a provider and complete an application form. You will need to provide proof of identity and address, and the provider will ask about your investment experience and knowledge. Some providers require a minimum opening deposit (often £1,000 to £5,000); others have no minimum.

Once your account is open, you transfer money in and instruct the provider which investments to buy. If you are transferring from another pension (such as an old workplace scheme), you can do a direct transfer — the old scheme pays the new SIPP provider directly, which avoids tax complications. If you are moving money from a previous SIPP, the transfer usually takes one to two weeks.

You are responsible for monitoring your investments and deciding when to buy, sell, or rebalance. If you do not feel confident making these decisions, you can pay a financial adviser to manage the SIPP for you, though this adds to your costs. Some SIPP providers offer a managed service where they handle investment decisions for a fee.

Frequently Asked Questions

Can I have more than one SIPP?

Yes, you can open multiple SIPPs with different providers. However, your total contributions across all pensions in a tax year cannot exceed £60,000 (or your annual earnings if lower). Each SIPP charges its own administration fee, so holding multiple accounts increases your costs.

What happens to my SIPP when I die?

If you die before age 75, your SIPP can usually pass to your beneficiaries tax-free. If you die after 75, your beneficiaries pay income tax on withdrawals at their marginal rate. You can name beneficiaries in your SIPP documentation, and the provider will contact them after your death.

Can I borrow money against my SIPP?

No. You cannot use your SIPP as security for a loan, and you cannot borrow money from the SIPP itself. This is a strict pension rule designed to prevent people using pensions as personal credit lines.

Is a SIPP worth it if I have a small pension pot?

Probably not. If your pot is under £50,000, annual SIPP fees typically consume a larger percentage of your returns than they would with a standard personal pension or workplace scheme. Calculate the fees as a percentage of your pot before opening a SIPP.

Can I transfer my workplace pension into a SIPP?

Yes, you can transfer most workplace pensions into a SIPP via a direct transfer. Some older schemes (called defined benefit schemes) have restrictions or require the scheme trustee's permission. Always check with your old scheme before requesting a transfer, as some schemes charge exit fees.
