UK SIPP Guide: A Practical Introduction for 2026/27
A Self-Invested Personal Pension gives you far more control over your retirement savings than a typical workplace scheme. This pillar guide explains how SIPP tax relief works, the £60,000 annual allowance for 2026/27, what you can and cannot invest in, typical provider fees, when a SIPP makes more sense than relying solely on a workplace pension, how and when you can access the money, and what happens to a SIPP when you die.
What Is a SIPP
A Self-Invested Personal Pension is a personal pension wrapper that gives the holder direct control over the underlying investments, in contrast to a typical workplace or stakeholder pension, which usually restricts members to a limited menu of pre-selected funds chosen by the scheme provider or employer. A SIPP is still a registered pension scheme, subject to the same HMRC tax rules as any other pension, but the "self-invested" element allows the holder to choose specific shares, funds and other permitted assets.
SIPPs are offered by dedicated SIPP providers, investment platforms, and some traditional pension companies, ranging from simple, low-cost "platform SIPPs" (aimed at investors who want a wide fund and share range at low cost) to full "bespoke SIPPs" (aimed at more sophisticated investors, including those wanting to hold commercial property).
The key appeal of a SIPP is flexibility and control: the ability to build a bespoke portfolio, consolidate old pensions in one place, and access a far broader investment universe than most employer-arranged schemes provide.
How Tax Relief Works
SIPP contributions attract Income Tax relief at your marginal rate. Under the standard "relief at source" method, if you pay in £80 the SIPP provider claims an additional £20 from HMRC automatically, grossing your contribution up to £100 — this reflects 20% basic rate relief applied at source, regardless of whether you are a basic, higher or additional rate taxpayer.
Higher rate (40%) and additional rate (45%) taxpayers must claim the further relief above the basic 20% through their Self Assessment tax return (or, in some cases, by contacting HMRC directly if they do not otherwise file a return). This effectively reduces the real cost of a £100 pension contribution to £60 for a higher rate taxpayer and £55 for an additional rate taxpayer, once the extra relief is claimed and received.
Scottish taxpayers receive relief according to the Scottish Income Tax bands, which differ from the rest of the UK — Scottish intermediate, higher and top rate taxpayers claim additional relief at their respective marginal rates in the same way, through Self Assessment.
The Annual Allowance
The standard pensions Annual Allowance for 2026/27 is £60,000, covering the total of all contributions — employer and personal, including the tax relief added — across all of your registered pensions combined, not per scheme. Tax relief on personal contributions is also capped at 100% of your relevant UK earnings for the tax year, so a contribution larger than your earnings will not receive relief on the excess even if it is within the £60,000 Annual Allowance.
High earners face a tapered Annual Allowance: those with "adjusted income" above £260,000 see their allowance reduced by £1 for every £2 of adjusted income above that threshold, down to a minimum floor of £10,000. Unused allowance from the previous 3 tax years can potentially be carried forward, provided you were a member of a registered pension scheme during those years, allowing a larger one-off contribution in a particular year.
Contributions above the effective allowance trigger an Annual Allowance Charge, effectively clawing back the tax relief on the excess at your marginal rate — a key reason to check your total pension contributions across all schemes before making a large SIPP payment, particularly if you also have a generous employer pension.
What You Can Invest In
SIPPs typically permit investment in individual UK and overseas listed shares, investment trusts, exchange-traded funds, a wide range of open-ended collective funds (unit trusts and OEICs), government and corporate bonds, and cash. Full or "bespoke" SIPPs also allow commercial property — including, subject to strict anti-avoidance rules, property used by the SIPP holder’s own business, provided a genuine commercial rent is paid to the pension and no personal benefit is taken improperly.
Certain assets are specifically excluded or heavily taxed if held in a SIPP, including residential property and most tangible moveable property (art, wine, classic cars, etc.) — HMRC treats these as "taxable property" for pension purposes, and holding them can trigger significant tax charges on the scheme, so it is important to check what a specific provider permits and what HMRC rules restrict before attempting an unusual investment.
Provider Fees
SIPP costs typically combine several layers: a platform or administration charge (often 0.15%-0.45% of assets per year, sometimes tiering down as the pot grows, or a flat annual fee for larger portfolios); underlying fund charges levied by the fund managers themselves (the Ongoing Charges Figure, commonly 0.05%-1%+ depending on whether funds are passive index trackers or actively managed); and dealing charges for buying and selling individual shares (often £5-£12 per trade, sometimes free for fund trades).
Because fee structures vary so much between providers — flat fee vs percentage, free share dealing vs charged, drawdown fees vs none — the cheapest provider for a small, passive fund-based portfolio may not be the cheapest for a large, actively traded share portfolio, and vice versa. Comparing total expected annual cost for your likely portfolio size and activity level, not just the headline platform fee, is essential before choosing a provider.
SIPP vs Workplace Pension
For most employees, contributing enough to a workplace pension to receive the full employer matching contribution should come first — turning down free employer money is rarely a good trade-off, regardless of how attractive a SIPP’s investment range might be. Workplace pension contributions also benefit from automatic tax relief (and, for salary sacrifice arrangements, National Insurance savings too) in the same way SIPP contributions do.
A SIPP tends to make most sense as an additional or complementary pension: for self-employed people with no workplace scheme at all, for consolidating old pension pots from previous employers into a single place, for those who want meaningfully more investment choice and control than their workplace scheme offers, or for higher earners looking to save beyond their workplace pension in a tax-efficient way. Many savers sensibly combine both — maximising the workplace match first, then using a SIPP for additional saving and investment flexibility.
Accessing Your SIPP
The Normal Minimum Pension Age is currently 55, and is due to rise to 57 from 6 April 2028 (with limited protections for some individuals who joined qualifying schemes before specific historic cut-off dates). From this age, SIPP holders can access their pension flexibly: up to 25% can typically be taken as a tax-free lump sum, subject to the Lump Sum Allowance of £268,275 for 2026/27, with the remainder drawn through flexi-access drawdown (taxed as income on withdrawal) or used to purchase an annuity for a guaranteed lifetime income.
There is no requirement to access the whole pension at once or in a single tax year — phasing withdrawals over several years can help manage the Income Tax due on taxable withdrawals, since large single-year withdrawals can push income into higher tax bands unnecessarily.
Death Benefits and IHT
SIPPs have historically offered favourable death benefit treatment. If the holder dies before age 75, remaining funds can typically be passed to nominated beneficiaries completely free of Income Tax, provided they are designated within the applicable time limits. If death occurs at or after age 75, beneficiaries can still inherit the fund, but any withdrawals they make are taxed at their own marginal Income Tax rate.
Pension death benefits have generally sat outside the deceased’s estate for Inheritance Tax purposes, making SIPPs a popular tool in later-life estate planning. However, the government has announced that unused pension funds and death benefits will be brought within the scope of Inheritance Tax from April 2027 — a significant upcoming change that anyone using a SIPP as part of estate planning should factor into their strategy well ahead of the change taking effect.
