SIPP UK 2026/27 — Self-Invested Personal Pension Guide, Providers and Rules

A SIPP (Self-Invested Personal Pension) is the most flexible pension wrapper available to UK savers. It offers the same tax relief as any pension — up to 45% depending on your income tax rate — but lets you choose exactly where your money is invested. For the self-employed, for people with old pensions scattered across previous employers, and for investors who want more control than a default workplace scheme allows, a SIPP is often the most important retirement account they will ever open.

This hub covers how SIPPs work, the key rules for 2026/27, when a SIPP makes sense over a workplace pension, how to choose a provider, and what the access and tax rules look like. For broader pension planning decisions, use the Pension Planning hub.

SIPP Key Rules 2026/27

How Tax Relief Works in a SIPP

Tax relief is the biggest financial advantage of a SIPP. When you pay money in, the government adds back the income tax you paid on those earnings.

The relief is always based on what you actually pay in. If you contribute £800 net, the provider claims £200, and £1,000 lands in your SIPP. Higher rate taxpayers must claim the extra 20% themselves, through Self Assessment or HMRC’s online claim service, because it does not happen automatically under relief at source.

Worked Example: SIPP vs No Pension for a Self-Employed Freelancer

Scenario: Maria is a self-employed graphic designer earning £55,000/year. She pays 40% income tax on earnings above £50,270.

• She contributes £5,000 into her SIPP (net payment)
• Provider claims £1,250 basic rate relief → £6,250 enters the SIPP
• She claims a further £1,250 higher rate relief via Self Assessment
• Net cost to Maria: £3,750 for £6,250 invested — an immediate return of 67%

Without a pension, that £3,750 after-tax saving would sit in a current account earning little. Inside a SIPP, it grows free of income tax and capital gains tax until withdrawal.

When a SIPP Makes Sense

Choosing a SIPP Provider

Provider type matters as much as the underlying investments:

Fee comparison matters most on larger pots. A 0.5% platform fee on a £500,000 pot costs £2,500/year. Over 20 years, switching from 0.5% to 0.25% saves tens of thousands of pounds in compounding.

SIPP vs Workplace Pension at a Glance

The right order: capture employer matching in your workplace scheme first. Then decide whether additional contributions go into the workplace scheme or a SIPP.

What a SIPP Can Hold

What Can You Invest In?

Allowed SIPP Investments

NOT Allowed in a SIPP

• Residential property (buy-to-let, holiday lets)
• Life insurance policies
• Fine wine, art, antiques, jewellery
• Tangible moveable property (unless HMRC-exempt)
• Loans to yourself or connected persons

Full SIPPs vs Low-Cost SIPPs

Full SIPPs (offered by specialist firms) allow commercial property and esoteric assets. Annual costs typically £500–£1,500.

Low-cost SIPPS (offered by investment platforms like Vanguard, Hargreaves Lansdown, AJ Bell, II) focus on funds, ETFs, and shares. Most investors don’t need a full SIPP.

Investment Strategy Inside a SIPP

For Long-Term Growth (20+ Years to Retirement)

A simple multi-asset portfolio is usually appropriate:

• Global equity index tracker (e.g., MSCI World ETF, Vanguard FTSE All-World): long-term core
• UK equity tracker (optional UK home bias)
• Bonds (as a % to reduce volatility as retirement approaches)

A common rule of thumb: hold (100 – your age)% in equities. A 40-year-old: 60% equities.

Lifestyling

Many workplace pensions automatically “lifestyle”, shift from equities to bonds/cash as you approach retirement. With a SIPP, you manage this yourself. If you plan to go into drawdown (rather than buy an annuity), you may not want to go very low on equities: you need growth to sustain 20–30+ years of income.

Low-Cost Strategy

Research by Vanguard and others consistently shows that total annual investment costs below 0.5% outperform active funds in the long run. A portfolio of:

• Vanguard FTSE All-World UCITS ETF (0.22% OCF)
• Vanguard UK Government Bond Index (0.12% OCF)

…costs less than 0.25% all-in on the fund side, before platform fees.

How to Draw Income from a SIPP

Once you reach the minimum access age, you have several options for taking money out:

Most SIPP holders use flexible drawdown because it keeps investment growth going and allows income to be timed around personal tax position. In years where you have little other income, you can draw more from the SIPP while staying within lower tax bands.

The MPAA trap: Once you start flexible drawdown, your future pension contribution limit drops from £60,000 to £10,000 (the Money Purchase Annual Allowance). This is a one-way door — you cannot reverse it. Anyone still earning and wanting to make significant future pension contributions should plan access timing carefully.

What Happens to a SIPP When You Die?

Unlike most assets, a SIPP sits outside your estate for Inheritance Tax purposes — until April 2027, when pension assets will become subject to IHT as part of wider estate planning changes. Until then:

• If you die before age 75, your SIPP can be passed on to nominated beneficiaries tax-free
• If you die aged 75 or over, beneficiaries pay income tax at their marginal rate on withdrawals
• The pot does not form part of your estate for IHT (until April 2027 rule change)
• Nomination form must be kept up to date — the pension trustees decide who receives the pot

This makes completing and regularly updating your SIPP nomination form critically important. See the Pension Nomination Form guide for the practical steps.
