SIPP Guide 2026/27 — Self-Invested Personal Pension Explained

A Self-Invested Personal Pension is a personal pension that puts you in charge of the investments. Unlike a workplace scheme with a narrow fund menu, a SIPP can let you choose individual shares, ETFs, investment trusts, funds, gilts and commercial property — subject to the provider’s rules. For 2026/27 the annual allowance is £60,000. Most people can take up to 25% of their pension benefits tax-free, subject to the £268,275 lump sum allowance and any protected allowance; the normal minimum pension age is 55, rising to 57 from 6 April 2028 for most people.

This guide covers how a SIPP works, the relief and limits, what you can invest in, the fees that silently eat returns, and the drawdown versus annuity decision.

How Tax Relief Works

Contributions are paid net of basic-rate relief: you pay £80 and the provider reclaims £20 from HMRC. Higher-rate and additional-rate taxpayers claim the balance on their Self Assessment return — an extra £20 or £25 per £100. On a £10,000 gross contribution the higher-rate taxpayer pays £8,000 net and receives the full £10,000 plus a £2,000 repayment, so the true cost is £6,000 — a 66% uplift before any investment growth.

Contribution Limits for 2026/27

The £60,000 annual allowance covers pension inputs across your pensions, including contributions from you, your employer and third parties. Separately, tax relief on personal contributions is generally limited to the higher of 100% of UK taxable earnings or £3,600 gross. Someone with £20,000 of relevant earnings may therefore have £60,000 of annual-allowance capacity in theory, but cannot normally obtain tax relief on personal contributions above the relevant-earnings limit. Taking flexible access — such as drawdown income or an uncrystallised funds pension lump sum — can trigger the £10,000 MPAA, which generally continues for later tax years and cannot be increased by carry forward for money-purchase contributions. Contributions above the applicable annual allowance can create an annual allowance charge.

What You Can Invest In

The breadth is the SIPP’s whole point — often a wider investment menu than a workplace scheme, subject to the provider’s permitted-investment list. Direct residential property and buy-to-let are generally not permitted in a SIPP, though REITs and property funds may be available. A £30,000 pot at £300 a month over 25 years at 5% growth reaches roughly £171,000 before tax; this is an illustration, not a forecast or guarantee.

Fees Matter More Than You Think

A 1% annual fee can reduce a final pot by 20–25% over 30 years compared with a 0.5% fee — charges compound against you exactly as returns compound for you.

Drawdown vs Annuity

Drawdown suits people who want control and can manage market risk; annuities suit those who value certainty. A combination is common — use drawdown for flexibility and a small annuity to cover fixed costs. Many people take the 25% tax-free cash first, then draw taxable income only when their marginal rate is low.

SIPP vs Workplace Pension

The rule of thumb is simple: take the full employer match in your workplace pension first — free money that beats any fee difference — then use a SIPP for additional contributions and wider choice. Many people run both: the workplace scheme for the matched contributions, a SIPP for the investments they actually want.

Transfers and Consolidation

Consolidating old pensions into a single SIPP is not automatically sensible — compare charges, guarantees, protected benefits and transfer terms first. A defined benefit pension with safeguarded benefits may require regulated financial advice before transfer when the cash-equivalent transfer value exceeds £30,000. Employer schemes should not be moved while you still work there without checking the effect on employer contributions. An overseas pension transfer can trigger a 25% overseas transfer charge unless an exemption applies, even where the receiving scheme is a qualifying recognised overseas pension scheme (QROPS).

Before consolidating, compare the exit penalties and fund charges on both sides: an old scheme charging 0.5% may be better than a SIPP charging 1.0% even if the SIPP is prettier. Where you have protected benefits — an old guarantee, a protected tax-free cash entitlement above 25%, or a protected pension age — a transfer can destroy them, so check the benefit protection statement before signing anything. For most people with a couple of small old pots, a single low-cost SIPP simplifies life and reduces fees; for anyone with defined benefit rights or protected benefits, the advice route is the only safe one.

A practical SIPP comparison

Compare the SIPP with the workplace scheme on the same basis. List employer matching, salary-sacrifice National Insurance effects, platform fees, fund charges, dealing costs, investment range, administration, transfer restrictions and retirement options. A wider menu is not automatically better if it encourages concentrated or high-turnover investing. The useful question is whether the SIPP solves a specific problem that justifies its extra control and cost.

Before opening an account, write down the intended contribution, investment approach, review date and access plan. Check whether the provider supports the assets you actually need, how it values commercial property, what happens to cash, and how beneficiaries are nominated. Revisit the comparison after a fee change, job change, transfer offer or flexible-access event. Keep the provider's fee schedule and key-features documents with the pension records rather than relying on a comparison website's historic figure.

SIPP Inheritance and Nomination Forms

A SIPP can be tax-efficient on death, but the result depends on the owner’s age, the type and timing of payment, the lump sum and death benefit allowance, scheme discretion and the date of death. If the owner dies before 75, most death benefits are usually free of income tax, but lump-sum death benefits above the owner’s £1,073,100 lump sum and death benefit allowance can be taxable. From 6 April 2027, most unused pension funds and pension death benefits are due to come within the deceased’s estate for Inheritance Tax, subject to the legislation and exceptions; the old blanket “outside IHT” statement is not safe for future deaths. A nomination helps the provider assess beneficiaries, but it does not guarantee a particular tax result or override every scheme rule.

Review the nomination whenever your circumstances change — marriage, divorce, a new child, or the death of a beneficiary all warrant an update, and the form takes minutes. Where beneficiaries are under 18, the pot can be held until they reach majority, and income can be paid to them tax-efficiently in the meantime. The interaction with the £60,000 annual allowance matters too: a beneficiary who inherits and later contributes cannot use the inherited pot to exceed their own allowance, and flexible access taken by a beneficiary triggers their own MPAA. Inheritance planning for pensions is a specialist area, but the basics — a valid nomination, an updated form, and an understanding of the 75 boundary — are available to every saver.
