Hargreaves Lansdown vs AJ Bell vs Vanguard: Which Platform Is Best?

The Big Three UK Investment Platforms

Hargreaves Lansdown, AJ Bell, and Vanguard UK are three of the most popular investment platforms in the country, each with a distinct positioning and fee structure. Choosing between them — or deciding whether a different platform entirely might serve you better — requires understanding what each offers, who they are designed for, and how their costs compare across different portfolio sizes.

Hargreaves Lansdown: The Comprehensive Choice

Hargreaves Lansdown is the UK's largest investment platform by assets under administration, with over £140 billion managed for more than 1.8 million clients. Its appeal is breadth: HL offers shares in thousands of companies worldwide, tens of thousands of funds and investment trusts, ETFs, gilts, corporate bonds, and more. The research tools, educational resources, and customer service are widely regarded as the best in the sector.

The costs reflect this premium offering. The platform charge is 0.45 per cent per year on funds — with a cap of £45 per year when holding shares and ETFs directly. Dealing fees are £11.95 per trade for shares and ETFs (falling to £8.95 for 10 or more trades per month). For a long-term passive investor buying and holding a small number of index funds or ETFs, HL is one of the more expensive options. For an active investor who values comprehensive research tools and maximum choice, the premium may be worth paying.

AJ Bell: The Balanced Option

AJ Bell sits comfortably in the middle of the market, offering a good range of investments at competitive fees with a clean, user-friendly interface. The platform fee is 0.25 per cent on funds and 0.25 per cent on shares and ETFs, capped at £3.50 per month for shares. Dealing fees are £9.95 per trade online, falling to £1.50 for regular monthly investments through the regular investing service.

AJ Bell's Dodl app offers a simplified, lower-cost version of the platform with a reduced fund range — a good option for beginners who want simplicity without sacrificing the security and regulation of a major provider. AJ Bell is particularly competitive for investors who hold a mix of funds and ETFs and make occasional additional trades.

Vanguard UK: The Low-Cost Specialist

Vanguard's own investment platform is specifically designed for investors who want to build a portfolio exclusively from Vanguard's range of index funds, ETFs, and LifeStrategy funds. The platform fee is a flat 0.15 per cent per year, capped at £375 annually — making it one of the cheapest options for larger portfolios. There are no dealing fees for buying Vanguard funds. ETF trades cost £7.50 each.

The limitation is significant: Vanguard UK does not offer third-party funds, individual shares, investment trusts, or non-Vanguard ETFs. For investors committed to a simple Vanguard index fund portfolio, this is no disadvantage at all. For those who want to diversify into specific sectors, individual stocks, or alternative fund managers, another platform is necessary.

Side-by-Side Fee Comparison

For a £10,000 portfolio invested in funds: Hargreaves Lansdown charges approximately £45 per year; AJ Bell charges approximately £25 per year; Vanguard charges approximately £15 per year. For a £100,000 portfolio in funds: HL charges approximately £450; AJ Bell charges approximately £250; Vanguard charges £150. At £200,000 in Vanguard funds: the 0.15 per cent cap means the fee stays at £300 — while HL would charge £900. At this level, Vanguard's fee cap becomes a very significant advantage for fund investors.

Which Should You Choose?

Choose Vanguard UK if you are a passive investor committed to a low-cost index fund strategy using Vanguard products, particularly if your portfolio is growing above £50,000 where the fee cap becomes increasingly valuable. Choose AJ Bell if you want a balance of reasonable fees, good investment range, and a clean interface for a mixed portfolio of funds, ETFs, and occasional share trades. Choose Hargreaves Lansdown if you value maximum investment choice, excellent research tools, top-tier customer service, and are prepared to pay a premium for it — particularly if you hold shares and ETFs directly where the £45 per year cap limits platform costs.
