Fidelity ISA & SIPP Review 2026

Overview

Fidelity — branded Fidelity Personal Investing in the UK — is one of the world’s largest investment companies and a long-established presence in the UK retail investment market. Their platform offers a broad range of funds, ETFs, and shares across ISA, SIPP and GIA accounts, alongside strong research tools and a well-regarded regular investing service.

The fee structure

Fidelity charges a tiered percentage fee. Funds carry no dealing charge and no annual cap. ETFs and shares are capped at £90/year but do carry a £7.50 dealing charge per trade — worth knowing if you trade shares or ETFs directly rather than through funds. SIPP fees mirror the ISA: 0.35% on funds up to £250,000 (falling to 0.2% and then 0.1% at higher tiers), with ETFs and shares capped at £90/year. Fidelity is FSCS-protected up to £85,000.

Fidelity’s fees are generally lower than Hargreaves Lansdown but higher than the cheapest alternatives. It occupies a similar market position to AJ Bell: full-service at below-HL pricing.

Who is Fidelity best for?

• Fund investors wanting a broad range at below-HL prices
• Investors valuing Fidelity’s research and fund analysis
• Regular investors — Fidelity’s regular investing service is well-regarded

Verdict

Fidelity is a solid choice for active fund investors. Less compelling for passive ETF investors (where InvestEngine or Vanguard offer better value) or for large portfolios (where ii’s flat fee wins). Use our calculator to compare at your portfolio size.
