Why consider an AJ Bell alternative?
AJ Bell is a strong, mid-priced SIPP with broad choice and a 0.25% platform fee. But it isn't the cheapest in every scenario: pure index investors can pay less at Vanguard, ETF-only investors can pay nothing at InvestEngine, and large pots can save with Interactive Investor's flat fee. The right alternative depends on what and how much you hold.
AJ Bell vs the alternatives
| Provider | Fee | Cheaper than AJ Bell when | Trade-off |
|---|---|---|---|
| AJ Bell | 0.25% | — | — |
| Vanguard | 0.15% (cap £375) | You only want index funds | Vanguard funds only |
| InvestEngine | 0% (ETFs) | You invest only in ETFs | ETF range only |
| Interactive Investor | £5.99–12.99/mo | Pot above ~£30k | Flat fee, less research |
| Fidelity | 0.35% (capped £90 over £25k) | Large fund-only pots | Higher headline fee |
Matching the alternative to your situation
If you invest purely in index funds, Vanguard's 0.15% beats AJ Bell's 0.25% — though you're limited to Vanguard's range. If you hold only ETFs, InvestEngine's 0% platform fee is unbeatable. And once your pot exceeds roughly £30,000, Interactive Investor's flat £5.99 a month (£71.88 a year) costs less than AJ Bell's percentage and keeps falling in relative terms as the pot grows.
What AJ Bell does well
- Broad choice of funds, shares, ETFs and investment trusts in one place.
- A capped £10/month charge on shares and a clean, well-regarded app (including Dodl for beginners).
- A sensible middle ground between Vanguard's simplicity and HL's premium service.

AJ Bell's place in the market
AJ Bell occupies the sensible middle ground: cheaper than Hargreaves Lansdown, broader than Vanguard, with a capped share charge and a clean app including the beginner-focused Dodl. For many savers it's the default "good enough for everything" choice. The case for an alternative arises only in specific situations — pure index investing, ETF-only portfolios, or large pots — where another provider's pricing model happens to fit better.
The flat-fee crossover
The clearest reason to leave AJ Bell is pot size. AJ Bell's 0.25% is uncapped on funds, so a £150,000 fund holding costs £375 a year. Interactive Investor's flat plan would charge a fraction of that. The crossover comes early — around £30,000 — beyond which the flat fee keeps widening its advantage. Savers with growing pots should keep an eye on this threshold and switch when the maths turns decisively in the flat fee's favour.
Index and ETF specialists
If your portfolio is simple, a specialist can undercut AJ Bell. An index-only investor happy with Vanguard's range pays 0.15% rather than 0.25%. An ETF-only investor on InvestEngine pays 0% platform fee, just the ETFs' own costs. These savings are modest in cash terms on small pots but compound meaningfully over decades, so they're worth capturing if your investing style fits the specialist's niche.
Weighing the move
- AJ Bell charges no exit fee, so you can leave without penalty.
- Choose Vanguard for index-only, InvestEngine for ETF-only, Interactive Investor for large pots.
- Keep AJ Bell if you want full choice at a moderate, predictable fee.
- Reassess whenever your pot crosses the flat-fee crossover point.

When to stick and when to switch
AJ Bell is a genuinely strong all-rounder, so for many savers the right answer is simply to stay put: it offers broad choice, a capped share charge and a clean app at a moderate, predictable fee. The reasons to switch are specific. If your pot has grown past roughly £30,000 and you mainly hold funds, Interactive Investor's flat fee will save you money that keeps growing as the pot does. If you invest only in index funds, Vanguard is a touch cheaper; if only in ETFs, InvestEngine charges nothing to hold them. None of these moves is urgent for a small or mid-sized pot, and AJ Bell's no-exit-fee policy means you can switch whenever the maths turns decisively in another provider's favour. The pragmatic approach is to treat AJ Bell as a solid default, keep an eye on the flat-fee crossover as your balance climbs, and switch only when a clear, lasting cost advantage emerges rather than chasing marginal differences.
Verdict
For index-only investors, Vanguard undercuts AJ Bell; for ETF-only portfolios, InvestEngine; and for pots above about £30k, Interactive Investor's flat fee wins. AJ Bell remains the best all-rounder if you want full choice at a moderate fee.
