What is a Self-Invested Personal Pension (SIPP)?

What Is a SIPP?

A Self-Invested Personal Pension (SIPP) is a type of UK personal pension that gives individuals greater control and flexibility over how their retirement savings are invested, compared to standard personal or workplace pensions.

In simple terms, a SIPP allows you to choose where your pension money is invested, while still benefiting from the same tax advantages as other pensions.

The role of a SIPP provider / Trustee

Typically, the role of a SIPP Provider and Trustee of a SIPP is to:

• Set up and administer the pension
• Hold assets within the SIPP
• Ensure the SIPP complies with HMRC and pension regulations
• Process instructions (contributions, purchases, sales, benefit payments)

Typically, a SIPP provider / Trustee does not:

• Choose investments
• Manage investment performance
• Monitor suitability
• Provide financial advice

Common misconceptions about SIPP providers and investments

A SIPP is best thought of as a tax-efficient pension wrapper that holds investments, not something that selects, manages, or monitors them for you.

It is quite common for people to believe the SIPP provider is responsible for managing their investments and monitoring investment growth. This will only be the case in limited circumstances, such as where that provider offers an investment platform.

How a SIPP Works – The Big Picture

A SIPP is set up with a pension provider or trustee, who administers the pension and ensures it complies with HMRC rules. You (or your adviser) decide how the pension funds are invested from a wide range of permitted assets.

The role of a Financial Adviser (if you have one)

SIPP Providers, such as Alltrust, will typically require you to have a regulated Financial Adviser, unless you are deemed to be a Knowledgeable Investor. The role of the adviser is to:

• Advise on whether a SIPP is suitable
• Recommend investments
• Review and manage investment strategy
• Assess risk and suitability

It is important to be aware that investment performance or suitability, is usually an advice issue, that relies upon a strategy agreed with the investment provider and financial adviser and is not an administration issue.

What Can You Hold Inside a SIPP?

One of the key features of a SIPP is its broad investment choice, which can include:

• Shares and equities
• Unit trusts and OEICs
• Investment trusts
• Exchange-traded funds (ETFs)
• Corporate and government bonds
• Commercial property
• Cash

The role of the Investment / Product Provider:

Examples of Investment and Product Providers can be:

• Fund managers
• Bond issuers
• Property managers
• Platform or discretionary managers

What they do:

• Run and manage the investment itself
• Control liquidity, valuations, and redemption terms
• Decide when funds can or cannot be released (subject to product rules)

If money cannot be released from an investment, this is usually due to investment-specific restrictions, not the SIPP provider.

Investment Risk – Who Is Responsible?

• All investment risk sits with the member
• The SIPP provider does not assess performance or suitability
• Losses arise from investment choices, not pension administration

This applies equally to:

• People who were historically mis-sold investments
• Knowledgeable Investors
• Experienced business owners

Contributions

• You, your employer, or both can pay into a SIPP
• Contributions benefit from tax relief:
  • Basic-rate taxpayers automatically receive 20% relief
  • Higher- and additional-rate taxpayers can claim further relief via self-assessment
• Contributions are subject to the annual allowance (currently £60,000 for most people)

See our section on contributions and allowances for more information.

This flexibility makes SIPPs particularly attractive to experienced investors and business owners.

Tax Benefits of a SIPP

SIPPs enjoy the same tax advantages as other registered pensions:

• Tax relief on contributions
• Tax-free growth on investments within the pension
• From age 55 (rising to 57 in 2028):
  • Up to 25% can usually be taken tax-free (subject to the lump sum allowances)
  • The remainder can be taken as income, taxed at your marginal rate

Accessing Your SIPP at Retirement

At retirement from age 55 (rising to 57 in 2028), a SIPP offers flexible options:

• Up to 25% can usually be taken tax-free (subject to allowances)
• Drawdown – keep funds invested and take income as needed
• Annuity purchase – convert some or all of the pension into a guaranteed income
• Lump sums – subject to tax rules and allowances

This flexibility allows retirement income to be tailored to individual needs and tax planning objectives. The role of the SIPP provider is to administer these options but does not advise which is best.

Is a SIPP Right for you?

SIPPs are not suitable for everyone. With greater control comes greater responsibility, and charges can be higher than simpler pension arrangements.

A SIPP may be suitable if you:

• Want control over investments
• Have investment experience or professional advice
• Are self-employed, a company director, or a higher earner
• Want to hold assets like commercial property in a pension

A SIPP may not be suitable if you:

• Prefer a “set and forget” pension
• Do not want responsibility for investment decisions
• Do not have access to advice

SIPP vs Standard Personal Pension

Summary

A SIPP is a flexible, tax-efficient pension that allows individuals to take control of how their retirement savings are invested.

It can be a powerful planning tool when used correctly, particularly for those seeking flexibility, choice, and long-term growth—but it should always be aligned with individual circumstances and retirement goals.

Key Things to Consider

• A SIPP is a container, not an investment
• The SIPP provider administers, but does not advise or manage
• Investment risk sits with the member and/or adviser
• Charges can vary depending on assets held
• Professional advice may be appropriate
• Rules and tax treatment can change
