A Self-Invested Personal Pension (SIPP) hands you the keys to your own retirement plan. Instead of letting an employer-chosen scheme decide where your money goes, you pick the platform, the investments, and how much you pay in — and the taxman tops up every contribution you make. For UK savers in 2026, that combination of control and generous tax relief makes the SIPP one of the most powerful long-term savings vehicles available.
SIPPs aren’t only for the wealthy. Self-employed workers, contractors, higher-rate taxpayers and anyone wanting to consolidate old pension pots can benefit. This guide covers how SIPPs work, the 2026/27 allowances, how the tax relief stacks up, and the leading UK SIPP providers — from full-service giants like Hargreaves Lansdown and AJ Bell to app-first newcomers like Penfold, PensionBee and Freetrade.
Key Takeaways
- The 2026/27 annual allowance is £60,000 or 100% of your relevant UK earnings, whichever is lower — and you can carry forward unused allowance from the previous three tax years.
- Basic-rate tax relief is added automatically: pay in £80 and the government tops it up to £100. Higher- and additional-rate taxpayers claim the extra 20% or 25% via self-assessment.
- Minimum access age is currently 55, rising to 57 on 6 April 2028. You can usually take 25% as tax-free cash up to a £268,275 lump sum allowance.
- Fees range from flat monthly subscriptions (Interactive Investor, Freetrade) to percentage-based charges with annual caps (Vanguard, AJ Bell, Hargreaves Lansdown).
- A SIPP rarely replaces a workplace pension where you get an employer match — but it’s often the best vehicle for consolidating old pots or saving on top.
What Is a SIPP and How Does It Work?
A SIPP is a type of personal pension that lets you choose your own investments inside a tax-advantaged wrapper. The “self-invested” bit is the key difference from a standard personal pension: rather than being limited to a small menu of insurer-managed funds, you can typically hold funds, ETFs, individual UK and overseas shares, investment trusts, corporate and government bonds, and — on some specialist platforms — even commercial property.
To open a SIPP you generally need to be a UK resident under age 75. The pension itself is a wrapper, not an investment, so it’s the underlying choices that drive your returns. SIPPs are regulated by the Financial Conduct Authority and qualifying investments are covered by the Financial Services Compensation Scheme up to £85,000 per provider should the platform fail (this protects against provider insolvency, not investment losses).
The Tax Relief Is the Real Magic
Tax relief is what makes a SIPP so attractive compared with a standard investment account. When you contribute, HMRC effectively refunds the income tax you’ve already paid on that money — so every £80 you put in becomes £100 inside the pension automatically (that’s the basic-rate relief, claimed on your behalf by the provider via “relief at source”).
Worked example — basic-rate taxpayer: Sam earns £30,000 and pays £200 into her SIPP. HMRC adds £50 in basic-rate relief, so £250 lands in her pension. Effective cost to Sam: £200 for £250 of pension contribution — a 25% uplift on the money she put in.
Worked example — higher-rate taxpayer: James earns £70,000 and pays £800 into his SIPP. HMRC adds £200 in basic-rate relief — so £1,000 goes into the pension. Because James is a higher-rate taxpayer, he can claim a further £200 (an extra 20%) via self-assessment, reducing his effective cost to £600 for £1,000 of pension contribution.
Claiming Higher- and Additional-Rate Relief
Basic-rate relief is automatic; higher-rate (40%) and additional-rate (45%) relief is not. You need to claim it on your self-assessment tax return or, if you don’t normally file one, by writing to HMRC. Many higher earners forget this step and miss out on hundreds or even thousands of pounds a year. You can usually backdate claims by up to four tax years, so it’s worth checking past returns.
How Much Can You Pay In?
The headline number for the 2026/27 tax year is £60,000 — but the rules around it have important nuances.
Annual Allowance
You can contribute up to £60,000 across all your pensions in 2026/27, or 100% of your relevant UK earnings if that’s lower. Earnings here means your salary, self-employed profits and similar — not investment income or rental income. The £60,000 cap includes employer contributions, your personal contributions, and the basic-rate tax relief added by HMRC. Non-earners can still contribute up to £3,600 gross (£2,880 net) each tax year.
Carry Forward
If you haven’t used your full allowance in the previous three tax years, you can “carry forward” the unused amount, potentially allowing a single contribution of up to £180,000 if you’ve had a SIPP open the whole time. You must use the current year’s allowance first, and your earnings in the current year must support the contribution.
Tapered Annual Allowance
High earners face a reduced allowance. If your “adjusted income” (broadly, your total taxable income plus employer pension contributions) exceeds £260,000 and your “threshold income” exceeds £200,000, your annual allowance is reduced by £1 for every £2 over £260,000. The minimum tapered allowance is £10,000 once adjusted income hits £360,000 or more.
Money Purchase Annual Allowance (MPAA)
If you’ve already taken flexible income from a defined contribution pension (anything beyond the 25% tax-free lump sum), your future annual allowance for money-purchase contributions drops to just £10,000. This is designed to stop people “recycling” pension cash to claim a second round of tax relief.
Best SIPP Providers UK 2026
Below are some of the most-used SIPP platforms in the UK. Fees, features and minimums change frequently, so always check the provider’s own site for the latest charges before opening an account.
Hargreaves Lansdown
The UK’s largest investment platform, with extensive research, a strong app and a wide range of investments. As of March 2026, HL cut its SIPP platform fee on funds to 0.35% (down from 0.45%) on the first £250,000, with the cap for share-only SIPPs reduced to £150 a year. Best for: investors who want a full-service, well-supported platform and don’t mind paying a little more for research and customer service.
AJ Bell
A long-standing low-cost competitor to HL. AJ Bell’s SIPP charges a 0.25% custody fee on funds (tapered down on larger pots) and caps share charges at £42 a year. Dealing fees apply, though regular investing was set to become free from May 2026. Best for: cost-conscious investors who want broad investment choice and a flexible platform without paying premium fees.
Interactive Investor
The UK’s only major SIPP platform with a flat monthly fee, which makes it dramatically cheaper than percentage-based rivals once your pot gets large. From February 2026, the Core plan costs £5.99 a month (covering ISA, GIA and SIPP combined) with a small pension admin add-on, scaling up through Plus and Premium tiers. Best for: investors with portfolios above roughly £50,000 who want predictable costs.
Vanguard SIPP
Cheap and simple but with a catch: you can only hold Vanguard’s own funds and ETFs. The platform fee is 0.15% capped at £375 a year (so big pots benefit), but accounts under £32,000 now pay a minimum £4 a month. Best for: long-term passive investors who want low-cost trackers and don’t need a wide investment menu.
PensionBee
Designed for consolidation: you tell PensionBee about your old workplace pensions and they handle the transfers, combining everything into a single managed plan. Annual charges range from 0.50% to 0.95% depending on the plan, with the fee halving on the portion of savings above £100,000. Best for: people with several old workplace pensions who want a hands-off, all-in-one solution.
Penfold
An app-first pension popular with self-employed savers and freelancers. Penfold is technically a personal pension rather than a true SIPP — you choose from a small menu of pre-built plans rather than self-selecting investments. The standard annual charge is 0.75%, dropping to 0.4% on amounts above £100,000. Best for: self-employed savers who want a simple, mobile-friendly pension without DIY investment decisions.
Freetrade
From January 2026, Freetrade made its SIPP free on all plans, including the Basic (free) plan. You pay nothing extra on top of any monthly subscription you already have for share dealing. The investment range is more limited than HL or AJ Bell, but it’s hard to beat on price. Best for: cost-focused investors comfortable with an app-only experience and a narrower investment menu.

SIPP vs Workplace Pension — Which Should You Use?
For most employees, the workplace pension is the right starting point because of the employer match. Under auto-enrolment, your employer must contribute at least 3% of qualifying earnings, and many add more — that’s effectively free money you’d be giving up by diverting contributions to a SIPP instead. Always pay in enough to get the full employer match before considering anything else.
A SIPP shines in three situations: when you’ve maxed out the employer match and want to save more, when you want to consolidate old workplace pensions from previous jobs into one place with better investment choice, and when you’re self-employed and don’t have an employer pension at all. Higher-rate taxpayers who use salary sacrifice through work may still get better effective relief that way, so always compare both routes.
SIPP vs Lifetime ISA
The Lifetime ISA (LISA) and SIPP both offer government top-ups, but they suit different people. A LISA lets you save up to £4,000 a year between ages 18 and 50, with a 25% bonus added by the government (up to £1,000 a year). Withdrawals are tax-free at 60, or earlier for a first home purchase up to £450,000. The SIPP allows much larger contributions (£60,000 a year), tax relief at your marginal rate, and access from age 55 (57 from 2028) — but withdrawals beyond the 25% tax-free portion are taxed as income.
As a rough guide: a higher-rate taxpayer usually gets more from a SIPP because the 40% relief beats the LISA’s flat 25% bonus. A non-taxpayer or someone saving for a first home often does better with a LISA. Many people use both — workplace pension first for the employer match, then SIPP or LISA depending on circumstances.
When Can You Access Your SIPP?
The current minimum age for accessing a SIPP is 55. From 6 April 2028, this rises to 57 — affecting anyone born after 6 April 1971. Some people with “protected pension ages” from older schemes may still be able to access earlier, but transferring out can lose that protection, so check carefully before consolidating.
From the minimum age, you can take up to 25% of your pot as a tax-free lump sum — known as the Pension Commencement Lump Sum (PCLS) — subject to the £268,275 Lump Sum Allowance that applies across all your pensions combined. The remaining 75% is taxed as income when withdrawn. The old Lifetime Allowance was abolished in April 2024 and replaced by the Lump Sum Allowance (£268,275) and the Lump Sum and Death Benefit Allowance (£1,073,100), which together cap the tax-free portion of pension payments over your lifetime.
How to Open a SIPP — Step by Step
- Decide what you need. Are you starting fresh, consolidating old pensions, or topping up alongside a workplace scheme? This affects which provider suits you best.
- Compare providers on fees, investment choice, and platform style (full-service vs app-only). Use the table above as a starting point, then check each provider’s current fee schedule.
- Open the account online. You’ll need ID, your National Insurance number and bank details. Most providers complete the process in under 20 minutes.
- Set up your contributions. A regular monthly direct debit is usually best for pound-cost averaging. Single lump sums also work — useful before tax year-end if you’re using carry forward.
- Choose your investments. If you’re unsure, a low-cost global tracker fund or multi-asset “ready-made” portfolio is a sensible default for most long-term savers.
- Transfer in old pensions if appropriate. Get details (provider, policy number, value) and request the transfer through your new SIPP provider — they’ll handle most of the paperwork. Always check for exit penalties or valuable guarantees on the old scheme first.
- Review annually. Check your contributions are still on track, your investments remain appropriate for your timeline, and your nominated beneficiaries are up to date.
Common SIPP Mistakes to Avoid
- Forgetting to claim higher-rate relief. The extra 20% or 25% won’t arrive automatically — you must claim it through self-assessment.
- Skipping the workplace match. Diverting money to a SIPP before maxing your employer’s contribution gives away free money.
- Transferring out a defined benefit (final salary) pension without specialist advice — these are usually too valuable to give up, and advice is legally required for transfers above £30,000.
- Overpaying. Contributing more than your earnings or the annual allowance triggers a tax charge that wipes out the relief.
- Holding too much cash. Cash inside a SIPP doesn’t compound — your money should normally be invested for the long term.
- Triggering the MPAA accidentally. Once you take flexible income, your future contribution limit drops to £10,000 a year — there’s no going back.
- Ignoring nominations. Your SIPP doesn’t pass through your will. Keep beneficiary nominations updated, especially after major life events.
Our Verdict
A SIPP is one of the most flexible long-term savings tools in the UK, but “best” is genuinely personal. If you want a full-service platform with research and customer support, Hargreaves Lansdown and AJ Bell are the established choices. If you have a larger portfolio and want predictable costs, Interactive Investor’s flat fees can save thousands over time. If you favour simplicity and consolidation, PensionBee or Penfold do the heavy lifting for you. And if cost is your top priority, Freetrade and Vanguard sit at the budget end — with quite different investment ranges. Whichever you pick, focus on the long term: low fees, sensible investments and regular contributions matter far more than picking a specific platform.
Frequently Asked Questions
How much can I pay into a SIPP each year?
In 2026/27, you can contribute up to £60,000 across all your pensions, or 100% of your UK relevant earnings, whichever is lower. Non-earners can pay in up to £3,600 gross. High earners may have a tapered allowance as low as £10,000, and anyone who has flexibly accessed a pension may be limited to £10,000 under the MPAA.
Can I transfer my old workplace pensions into a SIPP?
Yes, you can usually transfer old defined contribution workplace pensions into a SIPP, and most providers handle the paperwork for you. Before you do, check for exit charges, valuable guarantees (such as guaranteed annuity rates) or protected pension ages — these can be lost on transfer. Defined benefit transfers above £30,000 legally require regulated advice.
When can I access my SIPP money?
The current minimum age is 55. From 6 April 2028 this rises to 57 for anyone born after 6 April 1971. You can normally take up to 25% as a tax-free lump sum (capped by the £268,275 Lump Sum Allowance), with the rest taxed as income when you draw it.
What happens to my SIPP when I die?
Your SIPP passes to whoever you nominate as a beneficiary, outside your estate for inheritance tax purposes (under current rules). If you die before 75, beneficiaries can usually inherit the pot tax-free. If you die at 75 or later, they pay income tax at their own marginal rate on withdrawals. Pension death benefit rules are under active government review, so check the latest position before making major plans.
Are SIPP investments safe (FSCS protection)?
FCA-authorised SIPP providers are covered by the Financial Services Compensation Scheme up to £85,000 per person per institution, which protects you if the provider itself fails. It does not protect against falls in the value of your investments — that’s normal market risk and is a feature of any pension or investment account.
Should I get a SIPP or use my workplace pension?
If your employer offers matching contributions, contribute enough to get the full match before opening a SIPP — that’s effectively free money. A SIPP makes sense once you’ve maxed the match and want to save more, want better investment choice, or want to consolidate old pensions from previous jobs. Many people sensibly use both.
