Best SIPP UK 2026/27 — Self-Invested Personal Pension Providers Compared

Quick summary — our SIPP picks

What a SIPP actually is

A Self-Invested Personal Pension is a pension wrapper you control yourself. Legally it's a personal pension — same tax reliefs, same access rules, same withdrawal treatment. The difference from a workplace pension is that you pick the platform and the investments inside it.

The tax mechanics matter and are the reason SIPPs exist:

• Contributions get income tax relief at your marginal rate. Basic-rate taxpayers get 20% added automatically; higher- and additional-rate taxpayers claim the rest via Self Assessment.
• Investment growth inside the wrapper is free of Capital Gains Tax and dividend tax.
• At withdrawal (currently from 55, rising to 57 in April 2028), 25% is tax-free up to the Lump Sum Allowance (£268,275); the rest is taxed as income.
• Annual contribution allowance: £60,000 or 100% of your relevant UK earnings, whichever is lower. Tapered down for very high earners.

Who a SIPP is for

• People with multiple old workplace pensions — consolidating into one SIPP simplifies admin and can reduce fees.
• Self-employed workers without a workplace scheme. A SIPP is the primary pension vehicle for freelancers and directors.
• Higher- and additional-rate taxpayers topping up beyond workplace contributions — the tax relief on personal contributions is one of the strongest returns in UK personal finance.
• Investors who want more control than the fund range in a typical workplace pension offers.

Who should probably avoid a SIPP

• Anyone whose workplace scheme has employer matching they aren't using yet. Fill workplace matching first — free money beats platform choice every time.
• Defined-benefit (final-salary) scheme members considering transferring out. UK regulation requires authorised advice for transfers over £30,000. In most cases the DB scheme is worth more than a SIPP transfer value.
• Those who don't want to choose investments. A SIPP requires you to select funds. If that's off-putting, a NEST, Nest or workplace default fund is a better starting point.

The five UK SIPP providers we track

1. Hargreaves Lansdown — best for choice and service

The UK's biggest platform (over 1.9 million clients as of 2026). It's the most complete offering: full range of UK funds, ETFs, investment trusts, individual shares (UK and international), plus a well-regarded phone team and one of the most stable mobile apps in the sector.

Fees on the SIPP:

• Platform charge on funds: 0.45% up to £250k, tiered down to 0% above £2m
• Platform charge on shares/ETFs/investment trusts: 0.45% capped at £200/year
• Dealing: free for funds; £11.95 per share/ETF trade (cheaper with regular monthly investing)
• Drawdown: no separate charge, part of the platform fee

Best for: investors with mixed portfolios of funds, shares and ETFs; anyone who values phone support; drawdown users (HL's drawdown flexibility is well-regarded).

Trade-offs: fund platform fee at 0.45% is higher than InvestEngine or Vanguard for pure-ETF portfolios. If you only hold ETFs, you're overpaying vs specialists.

2. InvestEngine — best for low-cost ETF portfolios

InvestEngine launched to disrupt the fund platform market with a simple pitch: 0% platform fee on DIY ETF portfolios. That's genuinely competitive. It offers only ETFs (no OEICs, no individual shares, no investment trusts) and is designed for investors who know they want a passive, index-tracker portfolio.

Fees on the SIPP:

• Platform charge on DIY portfolios: 0%
• Managed portfolios: 0.25% platform + underlying ETF costs
• ETF trading: free
• Drawdown: currently free

Best for: ETF-only investors, cost-conscious pension savers, investors who want a mobile-first experience.

Trade-offs: no individual shares, no funds — if you want breadth, this isn't your platform. Younger platform than HL/AJ Bell, so less service history.

3. AJ Bell — best middle-ground SIPP

AJ Bell (formerly AJ Bell Youinvest) sits between HL and InvestEngine on fees and choice. Broad investment range including shares, ETFs and funds; capped fees on shares/ETFs; solid research tools; mature drawdown offering.

Fees on the SIPP:

• Platform charge on funds: 0.25% up to £250k, tiered down
• Platform charge on shares/ETFs: 0.25% capped at £120/year
• Fund dealing: £1.50
• Share/ETF dealing: £5 (£3.50 for regular investing)

Best for: investors who want more choice than InvestEngine at lower fund fees than HL. Mid-sized pots (£25k–£100k) benefit most.

Trade-offs: less stable app experience than HL; phone service is competent but not the strongest in the sector.

4. Vanguard Investor UK — best for Vanguard-only portfolios

Vanguard's UK platform holds only Vanguard products — LifeStrategy funds, Target Retirement funds, Vanguard ETFs. Cheapest possible route to a Vanguard portfolio: 0.15% platform fee capped at £375/year.

Fees on the SIPP:

• Platform charge: 0.15% capped at £375/year
• Dealing on funds and ETFs: free
• Drawdown: available with capped fees

Best for: investors who've decided Vanguard LifeStrategy or All-World ETFs are their portfolio and want the lowest cost route.

Trade-offs: if you ever want to hold non-Vanguard investments, you need a different platform. No individual shares.

5. Interactive Investor — best for larger portfolios

Interactive Investor (ii) is a flat-fee platform: you pay a fixed monthly amount regardless of pot size. That means it scales — the more you have, the cheaper it gets in percentage terms.

Fees on the SIPP:

• Pension Essentials plan: £5.99/month for pots up to £50k
• Pension Builder plan: £12.99/month for larger pots
• Free monthly regular-investment trades; one free trade per month included

Best for: SIPP pots over about £100,000 where the flat fee is cheaper than percentage-based platforms. Consolidated multi-pension holders.

Trade-offs: small pots pay proportionally more. If you only have £10k, £5.99/month is 0.72% — expensive.

Fee comparison at three pot sizes

The right SIPP depends on portfolio size. Here's the annual platform fee (excluding fund/ETF costs) on a fund-heavy portfolio:

Excludes fund OCF/TER, dealing fees, and drawdown charges. Rates current at time of review; verify at source.

Decision framework — which SIPP suits you

1. Do you know exactly what you want to hold? If it's Vanguard LifeStrategy or a couple of index ETFs — go with Vanguard Investor or InvestEngine.
2. Is your pot under £50,000 and you want fund choice? AJ Bell or Hargreaves Lansdown, depending on whether you value fees (AJ Bell) or service breadth (HL).
3. Is your pot over £100,000? Interactive Investor's flat fee usually wins, unless you value HL's service enough to pay for it.
4. Are you consolidating multiple old pensions? Hargreaves Lansdown or AJ Bell will handle the transfers competently.
5. Are you close to drawdown? HL's drawdown flexibility and phone team are worth the extra cost.

Pros and cons of a SIPP overall

SIPP vs Stocks & Shares ISA — which first?

The classic UK question. Neither is universally better; the answer depends on your tax band, when you'll need the money, and whether you'll have retirement tax-relief headroom.

• Higher-rate taxpayer now, basic-rate in retirement: SIPP wins. You claim 40% tax relief now and pay 20% on withdrawal (plus 25% tax-free lump sum).
• Basic-rate taxpayer, expects same in retirement: SIPP still slightly wins because of the 25% tax-free lump sum, but the ISA has better flexibility.
• Need the money before 55: ISA. SIPP is locked.
• Already maxing SIPP allowance or subject to tapered allowance: ISA is the next port of call.

See Cash vs Stocks and Shares ISA and our Pension Hub.

Drawdown flexibility — the retirement-phase difference

Accumulation is the easy part. When retirement arrives — usually 25-40 years after opening the SIPP — the platform's drawdown capability determines your options.

Flexi-access drawdown (FAD)

All five platforms above support flexi-access drawdown — take money as and when you want, up to 25% tax-free (subject to LSA), rest taxed as income. HL and AJ Bell have the smoothest UK drawdown flows and phone support. InvestEngine and Vanguard Investor UK support drawdown but with less hand-holding.

UFPLS (Uncrystallised Funds Pension Lump Sums)

Alternative to full drawdown — each withdrawal is 25% tax-free / 75% taxed. Useful for phased retirement. Supported at HL, AJ Bell, Interactive Investor. Some newer platforms don't yet.

Small pot rules

Pensions under £10,000 can be taken as small pot lump sums (up to 3 personal pensions in a lifetime) without triggering MPAA. Useful for tidying up. HL and AJ Bell handle this cleanly. See our Pension allowances guide.

MPAA trigger

Once you take taxable drawdown, your Money Purchase Annual Allowance drops to £10,000/year for future money-purchase contributions. All platforms have to enforce this. Plan around it if you're still working.

Transfer in — the practical process

Most SIPP conversions come from consolidating old workplace pensions. Providers handle transfers via the Origo Options electronic transfer system where possible — completes in 4-8 weeks. Cash transfers are default; in-specie is possible on HL and AJ Bell for compatible funds.

Before transferring in, check:

• Guaranteed annuity rates (GARs) — some old personal pensions include GARs paying 8-10% conversion rates. Never give these up.
• Safeguarded benefits — protected tax-free cash, protected retirement age.
• Defined-benefit components — over £30,000 transfer value requires FCA-authorised advice.
• Exit fees — mostly banned but check legacy schemes.

See our Pension transfer guide.

Contributions — how much you can put in

The Annual Allowance for 2026/27 is £60,000 or 100% of relevant UK earnings, whichever is lower. Additional considerations:

• Tapered allowance: reduced for adjusted income over £260,000, down to £10,000 minimum at £360,000.
• Carry-forward: unused Annual Allowance from previous 3 years can be added.
• MPAA: £10,000 cap on money-purchase contributions once taxable drawdown taken.
• Non-earners: up to £3,600 gross per year regardless of earnings — useful for spouses and children (Junior SIPP contributions £2,880 net = £3,600 gross).

See our Pension allowances guide.

Tax relief mechanics on personal contributions

SIPPs typically use Relief at Source. You contribute post-tax cash. HMRC adds basic-rate relief automatically. Higher- and additional-rate taxpayers claim the rest via Self Assessment.

Example — £8,000 contribution:

• You pay £8,000 into SIPP.
• HMRC adds £2,000 basic-rate relief automatically. £10,000 now invested.
• Higher-rate taxpayer: claim additional £2,000 via Self Assessment. Effective cost: £6,000 for £10,000 invested.
• Additional-rate taxpayer: claim additional £2,500. Effective cost: £5,500 for £10,000 invested.

See our Pension tax relief guide.

Death benefits and inheritance

SIPP death benefits currently sit outside your estate for IHT purposes (rules under review — check the latest Budget). Beneficiaries pay income tax on withdrawals only if you die after 75:

• Death before 75: Beneficiaries can take the pension tax-free (as lump sum or continued drawdown).
• Death after 75: Beneficiaries pay income tax on withdrawals at their marginal rate.

Nominate beneficiaries explicitly at your SIPP provider — the pension pot passes to whoever you name, outside probate. Update after major life events.

Real UK worked examples

Example 1 — Higher-rate consolidator

Priya (age 42, higher-rate, £70k salary) has three old workplace pensions totalling £60,000. Consolidates into HL SIPP for the research and consolidation. Adds £500/month personal contribution — £6,000/year gross, effective cost £3,600 after full higher-rate relief. Plans 20 more years at 6% growth: pot could reach £280,000+.

Example 2 — Self-employed via Ltd company

Marcus is a Ltd company director. Personal SIPP contributions get personal tax relief; employer contributions from the Ltd company save Corporation Tax. Uses InvestEngine SIPP (0% platform fee) with £2,000/month employer contribution + occasional personal top-ups.

Example 3 — Late-career consolidation for drawdown

Alex (age 55) has £350,000 across four old pensions. Consolidates to Interactive Investor SIPP for the flat fee (~£156/year vs ~£1,575 at HL). Uses phased drawdown — 25% tax-free lump sum for immediate needs, remainder in flexi-access for £14,000/year income within Personal Allowance.

What to check before opening any SIPP

• Are you giving up any guaranteed annuity rate on the old pension you're consolidating? These are valuable and often worth keeping.
• Is the pension you're transferring a defined-benefit scheme? Over £30,000 you must take FCA-authorised advice.
• Does the SIPP support drawdown, not just accumulation? Some cheap platforms don't offer full flexi-access drawdown.
• What are exit fees? Providers must have removed these under FCA rules, but confirm before transferring in.
• Are you within your annual allowance (£60,000 or 100% of relevant UK earnings)? Excess contributions trigger a tax charge.

Frequently asked questions

What is a SIPP?

A Self-Invested Personal Pension is a UK pension wrapper you control yourself, letting you hold a wide range of investments — funds, ETFs, shares, bonds — with the same tax relief and rules as a workplace pension. Contributions attract tax relief up to your annual allowance (currently £60,000).

Which is the best SIPP provider in the UK?

There is no single "best" — the right SIPP depends on your portfolio size, investment choice, and whether you'll enter drawdown. Hargreaves Lansdown suits investors wanting the widest choice and best service; InvestEngine suits low-cost ETF portfolios; Vanguard and AJ Bell sit between them on fees and choice.

Can I transfer an existing pension into a SIPP?

Yes, most workplace and personal pensions can be transferred into a SIPP, subject to a few exceptions (guaranteed annuity rates, defined benefit schemes over £30,000 require advice). Providers typically handle the transfer paperwork for you.

When can I access money in a SIPP?

Currently from age 55 (rising to 57 in April 2028). You can take up to 25% as a tax-free lump sum (capped at £268,275 under the Lump Sum Allowance); the rest is taxed as income when drawn.

Is SIPP money protected if the provider fails?

Yes. Investments in a SIPP are held in your name at the underlying fund manager or custodian, not on the platform's balance sheet. FSCS also protects up to £85,000 per person per platform for investment claims where a platform fails and can't return your assets.

Summary

The best SIPP is the one that matches your portfolio size and investment approach. Hargreaves Lansdown for widest choice and service; InvestEngine for low-cost ETF portfolios; AJ Bell for the middle ground; Vanguard Investor for Vanguard-only holdings; Interactive Investor for larger consolidated pots.

Next steps
