Best SIPP Providers UK 2026: Compare Fees, Investment Options & Minimum Deposits
A data-led comparison of nine leading platforms — covering platform fees, tax relief processing, investment range, and drawdown options — with an interactive cost calculator.
Fees matter more in a SIPP than in an ISA. A pension pot can sit invested for 30–40 years before drawdown, and a 0.1% annual fee difference on a £100,000 pot costs approximately £3,800 in compounded returns over 20 years — before a single trade is placed. Choosing the right provider is one of the highest-leverage financial decisions you will ever make.
This guide covers nine leading SIPP providers as of June 2026. Each entry covers the full fee structure, investment universe, tax relief processing, drawdown availability, and a plain-English verdict on who it suits best.
The 9 best SIPP providers for 2026
AJ Bell is a FTSE 250-listed, FCA-regulated platform and one of the UK’s most trusted investment services. Its fee structure is cleverly tiered: the 0.25% platform charge is capped at just £10/month (£120/year) for portfolios holding only shares, ETFs, and investment trusts. For a £200,000 ETF portfolio, this works out to an effective rate of 0.06% — among the lowest available on any full-service platform. Tax relief is processed efficiently, with HMRC top-ups typically reinvested within 6–8 weeks. Flexi-access drawdown is available at no additional charge beyond the standard platform fee.
Interactive Investor is the UK’s second-largest direct investment platform (part of the abrdn Group) and its flat-fee model is the defining differentiator in the SIPP market. The Core plan at £5.99/month — approximately £72/year — costs the same whether your pot is £50,000 or £500,000. At £100,000 the effective rate is 0.072%; at £250,000 it falls to 0.029%. One free trade per month is included, which effectively covers a regular monthly contribution at zero dealing cost. The breadth of 40,000+ instruments across 17 global exchanges makes it equally suitable for sophisticated investors building international portfolios.
Vanguard’s SIPP is ideally suited to investors who want a fully passive, low-cost retirement strategy within Vanguard’s own ecosystem. The 0.15% platform fee is the lowest percentage-based rate on this list, capped at £375/year — meaning a £250,000+ pot pays a fixed maximum. Target Retirement funds are available within the SIPP, automatically shifting the asset allocation from growth-oriented to defensive as you approach your chosen retirement date. There are no dealing charges on any transaction, making it completely cost-transparent for a fund-only approach.
InvestEngine is the only major UK platform offering a genuinely zero-fee DIY pension. There are no platform charges and no dealing fees — the only investment cost is the underlying ETF’s ongoing charge figure (OCF), which is unavoidable regardless of which platform you use. Fractional ETF investing ensures 100% of contributions and HMRC tax relief top-ups are deployed immediately with no uninvested cash drag. The 700+ ETF range covers global equities, bonds, commodities, REITs, and factor strategies — sufficient for a comprehensive passive portfolio.
Fidelity is one of the world’s largest asset managers and its SIPP benefits from institutional-grade research and tooling. A distinctive feature is household account linking: family members can pool their assets to reach Fidelity’s lower fee tiers faster. The Junior SIPP carries no service fee, making Fidelity the leading choice for intergenerational pension planning. Fund dealing is free, and Fidelity’s own index fund range — including the popular Fidelity Index World Fund — offers some of the lowest OCFs available. The 0.35% base fee is higher than some rivals, but the household discounts and free fund dealing offset much of this for families.
Hargreaves Lansdown is the UK’s largest retail investment platform and its SIPP is the most feature-rich on this list. The Wealth Shortlist provides independently curated fund research. UK-based telephone support is available six days a week — a significant differentiator when managing something as important as a pension. Integration with HL Active Savings allows uninvested pension cash to be swept into high-interest notice accounts with a single click. The 2026 fee reduction to 0.35% improved HL’s competitiveness, but for fund investors with large pots, it remains materially more expensive than Interactive Investor or AJ Bell.
In a significant 2026 update, Freetrade included SIPP access in its free Basic plan — making it one of two providers here with a zero-cost pension wrapper. Commission-free trading across UK and US stocks makes it attractive for active traders. The key cost to model is the FX fee: international trades incur a 0.45%–0.99% foreign exchange charge. For a £10,000 purchase of US equities at 0.45%, the FX cost is £45 — comparable to several flat-fee trades. Customer service is app and email only — there is no telephone support, which is a meaningful limitation for a product as important as a pension.
Bestinvest occupies a distinctive position in the market: it offers free 45-minute sessions with FCA-qualified financial coaches who will review your pension goals and investment approach at no charge. This is uniquely valuable for investors who want more than a robo-advisor but aren’t ready to pay for full financial advice (which typically costs £150–£300 per session). Their “Smart” ready-made portfolios start at 0.20% — among the lowest managed-portfolio costs in the UK. Bestinvest is part of Evelyn Partners, a major UK wealth management firm with strong institutional backing.
Halifax Share Dealing is part of Lloyds Banking Group — one of the most financially stable institutions in the UK. Its SIPP charges a flat £198/year administration fee regardless of pot size. For a £500,000 pension pot, this equates to an effective rate of just 0.04% — the lowest available for any full-service bank-backed platform. Integration with Halifax and Lloyds current accounts makes management seamless for existing customers. The platform interface is dated and the £9.50 dealing fee is relatively high, making this most suitable for investors who contribute infrequently and hold a large, diversified portfolio over the long term.

How to choose the right SIPP provider
The optimal provider depends on three variables: your current pot size, how often you trade, and whether you want a managed or DIY approach.
The percentage vs. flat fee crossover point
The single most important decision in SIPP provider selection is understanding when a flat fee becomes cheaper than a percentage. For Interactive Investor’s Core plan at £5.99/month (£72/year), the crossover versus AJ Bell (0.25%) occurs at £28,800. Against Hargreaves Lansdown (0.35%), it occurs at approximately £20,600. Every pound your pot grows above those thresholds is a saving you make by being on a flat-fee platform.
Why drawdown matters when choosing your provider
Most investors open a SIPP for accumulation but don’t think about drawdown until much later. Check upfront whether your provider includes flexi-access drawdown at no additional charge, or imposes a separate fee when you begin taking income. All nine providers on this list offer some form of drawdown, but the terms vary. Interactive Investor and AJ Bell are particularly strong for drawdown given their flat or capped fee structures that don’t scale with a growing pot in retirement.
