A Self-Invested Personal Pension (SIPP) is a type of UK personal pension that gives you direct control over where your retirement savings are invested. Instead of a pension provider making investment decisions on your behalf, you choose from a wider universe of assets — funds, shares, bonds, investment trusts, commercial property, and more.
That freedom is genuinely valuable — in the right hands. In the wrong hands, a SIPP becomes an unnecessarily complex arrangement with higher fees and worse outcomes than a simpler personal pension. Here’s how to assess which category you’re in.
What a SIPP Is (and Isn’t)
A SIPP is a personal pension wrapper — a tax-advantaged account that holds investments for retirement. What distinguishes it from a standard personal pension is the breadth of investment options available and the degree of control the holder has over those choices.
It is not a product that generates returns on its own — its performance depends entirely on what you invest in. A SIPP invested in a global index fund will produce different outcomes than one invested in speculative single stocks or esoteric alternative assets. The wrapper is neutral; the investment decisions are everything.
The Tax Advantages
SIPPs carry the same tax advantages as all UK registered pension schemes:
- Tax relief on contributions: basic-rate taxpayers receive 20% tax relief automatically — meaning a £80 contribution becomes £100 in the pension. Higher-rate and additional-rate taxpayers can claim further relief through their self-assessment tax return (40% and 45% respectively).
- Tax-free growth: investments inside a SIPP grow free of income tax and capital gains tax
- Tax-free lump sum at retirement: up to 25% of the fund (capped at £268,275 under current rules) can be taken tax-free at or after age 55 (57 from 2028)
- Inheritance planning: SIPPs typically fall outside of your estate for inheritance tax purposes — passing to nominated beneficiaries free of IHT, though income tax may apply on withdrawals depending on the age at death
💡 Higher-rate taxpayers: If you pay 40% income tax, pension contributions are one of the most efficient tax planning tools available. A £10,000 contribution effectively costs you £6,000 after tax relief — and grows tax-free.
What You Can Invest In
A full SIPP (as opposed to a low-cost “lite” SIPP) allows investment in:
- UK and international stocks and shares
- Funds (unit trusts, OEICs, ETFs)
- Investment trusts
- Government and corporate bonds
- Commercial property (not residential)
- Cash and cash-like deposits
Permitted investments do not include residential property, most collectibles, or most “tangible moveable property.” The restrictions exist to prevent abuse of the tax advantages. Anyone suggesting a SIPP can invest in holiday lets, buy-to-let property, or rare coins is describing something that will create significant HMRC issues.
Contribution Limits
- You can contribute up to 100% of your annual earnings, subject to the Annual Allowance (£60,000 in 2026)
- Non-earners can contribute up to £3,600 gross (£2,880 net) per year
- Unused allowance from the previous 3 tax years can be carried forward — useful for high-income years or irregular earners
- The Money Purchase Annual Allowance (MPAA) of £10,000 applies once you start drawing flexible income from any pension — if you’ve triggered flexi-access drawdown, future pension contributions are capped
Drawdown in Retirement
From age 55 (57 from 2028), SIPP holders can access benefits flexibly:
- Tax-free cash: take up to 25% (or the capped amount) as a tax-free lump sum
- Flexi-access drawdown: leave the remainder invested and draw income as needed — taxable as income in the year received
- Uncrystallised funds pension lump sum (UFPLS): take lump sums directly from the fund, where 25% of each payment is tax-free
- Annuity purchase: use part or all of the fund to buy a guaranteed income for life from an insurance company
Many SIPP holders use a combination — taking the tax-free cash, entering drawdown with the remainder, and purchasing an annuity with a portion later in retirement for guaranteed income. There’s no single right answer; it depends on other income, health, longevity expectations, and tax position.
Is a SIPP Right for You?
A SIPP makes most sense if:
- You’re self-employed and want full control over your pension investment
- You’ve accumulated pensions from multiple employers and want to consolidate into one place you control
- You’re a higher-rate taxpayer who wants to access the full range of investment options
- You want to invest in specific assets (e.g., a commercial property your business occupies) not available in standard personal pensions
- You’re financially engaged and willing to make active investment decisions
A SIPP is probably not the right primary vehicle if you want a simple, hands-off pension arrangement — a workplace pension scheme or standard personal pension with sensible default funds will likely serve you as well at lower cost and less complexity.
Frequently Asked Questions
Q: How much does a SIPP cost?
Low-cost platform SIPPs (Vanguard, Fidelity, AJ Bell, Hargreaves Lansdown) charge annual platform fees of 0.15–0.45% of assets, often capped at a fixed amount for larger funds. Full SIPPs with property investment capability have higher fixed costs — typically £200–£500+ per year plus transaction fees. For most investors investing in funds, a low-cost platform SIPP is entirely adequate.
Q: Can I have a SIPP and a workplace pension?
Yes — you can hold both simultaneously. Your total contributions across all pension schemes in a tax year must stay within the Annual Allowance (£60,000 in 2026). Many people contribute to their workplace pension to capture the employer match, then use a SIPP for additional personal contributions with broader investment choice.
