Best SIPP UK 2026: Charges Compared

A Self-Invested Personal Pension (SIPP) is a private pension wrapper that you control directly. You choose the funds, ETFs, or individual shares it holds, when you contribute, and how it's invested in retirement. The wrapper itself gives you the same tax advantages as any UK pension: contributions get income-tax relief on the way in, growth is tax-free inside the wrapper, and you can take 25% as a tax-free lump sum from age 55 (57 from April 2028).

A SIPP is the pension equivalent of a Stocks and Shares ISA: a self-directed wrapper that you fund from your own bank account. It is distinct from a workplace pension where your employer chooses the provider and often contributes alongside you. Most readers benefit from holding both: the workplace pension captures employer matching (which is the highest-leverage money in UK personal finance), and the SIPP captures everything beyond that and any contributions you want to make for tax-relief reasons.

The headline benefit. When you contribute £100 of your own money to a SIPP, HMRC adds 25% basic-rate tax relief automatically, making the gross contribution £125. If you're a higher-rate taxpayer (paying 40% above £50,270), you claim a further 20% via self-assessment, getting £25 back as a tax refund. An additional-rate taxpayer claims 25% back, getting £31.25 back.

Net cost to put £125 into your pension:

• Basic rate taxpayer: £100 (just the auto top-up).
• Higher rate taxpayer: £75 (after claiming higher-rate relief).
• Additional rate taxpayer: £68.75.
• Someone in the 60% tax trap between £100k and £125,140: £47.50 (because every £1 sacrificed avoids 60p of effective tax).

The higher your marginal tax rate, the more pension relief is worth. This is why the standard advice for higher-rate and additional-rate taxpayers is to max pension contributions before any other tax-advantaged wrapper.

A workplace pension comes with an employer-matched contribution, typically 3% from the employer if you contribute 5%. That match is calculated on qualifying earnings - the band of pay between £6,240 and £50,270 - so the headline "8%" almost always works out at 6-7% of your actual gross salary. Still the most valuable money in UK personal finance: a 100% return on day one for matched contributions, on top of the tax relief.

Never turn down employer matching to fund a SIPP instead. The match is worth more than any platform-cost advantage a SIPP can offer.

Where the SIPP beats the workplace pension:

• Cost. Workplace default funds typically charge 0.40% to 0.75%. A SIPP with a global tracker can be 0.22% all-in.
• Fund choice. Most workplace schemes give you 5-15 fund options. A SIPP gives you the whole market.
• Control over consolidation. You can transfer old workplace pensions into a SIPP to get one login, one fund range, one fee schedule.

The usual playbook: contribute enough to your workplace pension to maximise the employer match, then route any additional pension savings into a SIPP. Our SIPP vs workplace pension deep dive walks through the trade-offs.

Three caps to know:

• Annual allowance: £60,000 of gross contributions per tax year (2026/27), across all pension wrappers including employer contributions. This is the upper limit on tax-relievable contributions.
• Earnings cap: tax relief is only granted on contributions up to 100% of your relevant UK earnings. Earn £45,000? Your max relievable contribution is £45,000 even if you'd want to put in more.
• Tapered annual allowance: for very high earners (adjusted income above £260,000), the £60k allowance tapers down to as low as £10,000. The pension carry-forward calculator handles both the taper and the carry-forward rules.

Also worth knowing: the Lifetime Allowance was abolished in April 2024, so there's no longer a cap on the total pension pot you can build up tax-efficiently. Pots over £1,073,100 (the old LTA) are still subject to a separate Lump Sum Allowance of £268,275 on the tax-free cash element, but the growth itself is no longer penalised.

Three numbers do most of the work:

• Platform fee - usually charged as a percentage of pot size (HL 0.35%, AJ Bell 0.25%, Vanguard 0.15%) or a flat monthly fee (Interactive Investor £8.49/month for Core + SIPP). Below ~£70k the percentage providers usually win; above that the flat-fee providers do.
• Dealing costs - the per-trade charge for buying funds, ETFs, or shares. Trading 212 is free; Vanguard is free for own funds; HL is £6.95 per share trade. If you contribute monthly via direct debit and buy the same fund every time, dealing costs barely matter. If you rebalance frequently or hold individual shares, they matter a lot.
• Fund choice - whether the platform offers the funds you actually want. Vanguard SIPP only holds Vanguard funds. AJ Bell, HL, and Interactive Investor give you whole-market access. Trading 212 currently has a narrower SIPP fund list than its ISA but it's expanding.

For most readers building a SIPP with a single all-world tracker (HSBC FTSE All-World, Vanguard FTSE Global All Cap, or LifeStrategy 100), Trading 212 wins on cost up to ~£70k. From there, Interactive Investor's flat-fee structure pulls ahead. Vanguard is the safe default if you only ever want Vanguard funds. AJ Bell is the right middle ground if you want broad fund choice with reasonable fees.

From age 55, rising to 57 in April 2028 and likely 58 later. At access age you have several options:

• Take 25% as a tax-free lump sum (capped at £268,275 lifetime under the Lump Sum Allowance).
• Move the remaining 75% into drawdown and withdraw flexibly. Withdrawals are taxed as income at your marginal rate.
• Buy an annuity with all or part of the pot. The annuity converts your fund into a guaranteed income for life.
• Take Uncrystallised Funds Pension Lump Sum (UFPLS) - 25% tax-free, 75% taxed as income, all in one go or in chunks.

Most early retirees use a mix: take the 25% tax-free lump sum (often to clear a mortgage or fund an emergency reserve), then drawdown from the remaining 75% at a rate that keeps them inside the basic-rate income tax band, supplemented by ISA withdrawals which are 100% tax-free. The drawdown calculator lets you model the trade-off between drawdown rate and pot longevity.

Most brand-specific SIPP searches end up wanting the same answer: how much does my chosen provider actually charge, and is it competitive? The honest comparison, provider by provider:

• Trading 212 SIPP: 0% platform fee, free dealing on ETFs and shares, 0.15% FX fee on USD/EUR holdings. ETF-only (no mutual funds inside the SIPP). The cheapest UK SIPP available for pots up to roughly £100,000 holding a global tracker ETF like VWRP. Newer UK SIPP entrant (launched 2023) so a shorter track record than the incumbents.
• Vanguard SIPP: 0.15% platform fee capped at £375 per year above £250,000. Free dealing on Vanguard own funds; £4 per ETF trade. Vanguard funds only (LifeStrategy, Target Retirement, FTSE Global All Cap). The right SIPP for someone who only ever wants Vanguard funds and a hard fee cap; cheaper than HL or AJ Bell at all but the smallest pots.
• AJ Bell SIPP: 0.25% platform fee on funds (tapering to 0.10% above £250,000, nothing above £500,000). £120/year cap (£10/month) on ETFs and shares custody. £1.50 per fund trade; £5 per share trade. Whole-market fund choice. Reasonable middle ground if you want both funds and shares; loses to Trading 212 on cost below £100,000 and to Interactive Investor on cost above £100,000.
• Fidelity SIPP: 0.35% platform fee tiered down to 0.20% above £250,000 and 0% above £1 million. Free fund dealing with regular investing; £7.50 per share trade. Strong fund range. Mid-table for cost on smaller pots but the tiered drop makes it more competitive at very large balances.
• Hargreaves Lansdown SIPP: 0.35% platform fee on funds, tapering to 0.25% above £250,000 and 0.10% above £1 million (£150 annual cap, £12.50/month, on shares/ETFs custody). £6.95 per share trade dropping to £3.95 above 20 trades a month; free fund dealing. The gold standard for UX, research, and customer service in the UK SIPP market, and the most expensive of the seven on funds. Roughly 2x what Trading 212 or Vanguard charge.
• Interactive Investor SIPP: flat £8.49/month (Core plan + SIPP add-on) regardless of pot size. £3.99 trades on the Investor plan; free regular investing. The flat-fee structure means it gets relatively cheaper as the pot grows. At £200,000 you pay roughly £102/year vs £700 on HL, £500 on AJ Bell, or £300 on Vanguard. The right SIPP for pots above £70,000 to £100,000.
• PensionBee: managed-pension provider with all-in fees of 0.50% (£100k pot) down to 0.35% (£500k+). Run as a consolidation product for old workplace pensions rather than a DIY SIPP. Convenient but materially more expensive than running the same global tracker on Trading 212 or Vanguard.

The underlying pattern: SIPP charges range from 0% to 0.50% per year for the same underlying investment. Across a 30-year holding period that range is worth six-figure differences in final pot value. The single highest-leverage move most readers can make on their pension stack is moving from a 0.40-0.50% provider to a 0.15% or below provider, which usually means an in-specie transfer to Trading 212, Vanguard, or Interactive Investor depending on pot size.
