Comparison · Investment Platforms · UK

AJ Bell and Hargreaves Lansdown are probably the two most directly comparable investment platforms in the UK — similar fund ranges, similar products, similar quality. The main difference is cost, and it is a meaningful one over a long investing horizon. I find this a more interesting comparison than Vanguard vs HL because the decision is genuinely close and the right answer actually depends on how you invest.
My honest view — not financial advice — is that for most people investing primarily in funds, AJ Bell wins on value. For people who trade shares frequently or want HL's specific customer service reputation, HL justifies its higher cost. The nuance is in understanding when each argument applies to you.
AJ Bell charges 0.25% per year for funds, capped at £3.50 per month (£42 per year) for fund portfolios above £16,800. Hargreaves Lansdown charges 0.45% for funds with no cap on pension holdings. For shares, HL caps at £45 per year in an ISA — which makes it very competitive for share-heavy portfolios.
| Portfolio size | AJ Bell (funds) | HL (funds) | Annual saving with AJ Bell |
|---|---|---|---|
| £20,000 | £42 (capped) | £90 | £48 |
| £50,000 | £42 (capped) | £225 | £183 |
| £100,000 | £42 (capped) | £450 | £408 |
| £250,000 | £42 (capped) | £1,125 | £1,083 |
At larger fund portfolio sizes, AJ Bell's fee cap makes it dramatically cheaper than HL. On a £250,000 fund ISA or SIPP, AJ Bell costs £42 per year versus £1,125 for HL — a saving of over £1,000 annually. That difference, compounded over 10 years, is significant.
The comparison flips for share-heavy portfolios. HL caps at £45 per year for share ISAs, making it cheaper than AJ Bell (which charges per trade) for people holding a large portfolio of individual shares. If you primarily hold funds or ETFs, AJ Bell wins. If you primarily hold individual shares in an ISA, HL can be cheaper.
Both platforms give access to thousands of funds, ETFs, investment trusts, and individual UK and international shares. The practical difference between them for most investors is smaller than the marketing suggests. Both have Vanguard index funds, iShares ETFs, popular investment trusts, and active funds from major managers.
HL has a slight edge at the margins — more obscure funds, better research tools, a wider range of structured products. For the kind of investor who regularly researches individual funds and wants the widest possible selection, HL's breadth is a genuine advantage. For the kind of investor who picks an index fund and leaves it alone, both platforms are equivalent in everything that matters.
This is the one area where I think HL has a clear, consistent edge. HL's phone support is well-resourced and generally responsive. Their online tools and platform have been refined over many years and are among the most polished available. For investors who value being able to speak to someone when something goes wrong — particularly for larger portfolios or more complex situations — HL's customer service reputation is deserved.
AJ Bell's customer service is good but not HL-level. The platform is clean and functional, but the support infrastructure is smaller. For investors comfortable managing everything online without frequent support needs, this rarely matters in practice. For investors who want human support readily available, it might.
AJ Bell has a strong reputation specifically for its SIPP — the company was founded with pensions at its core and pension administration is central to what it does. The SIPP fee cap of £3.50 per month makes it very cost-effective for fund-based pension saving, and the drawdown options are comprehensive.
HL's SIPP is also excellent and the drawdown tools are more polished — useful for people actively managing retirement income rather than purely accumulating. For straightforward pension accumulation over 20-30 years, I find it hard to justify HL's higher fee when AJ Bell provides the same core functionality at a fraction of the cost. For more complex retirement income management approaching and in retirement, HL's tools are worth considering.
