Overview

AJ Bell is one of the UK’s largest investment platforms and a FTSE 250 company. It occupies a middle ground between the premium service of Hargreaves Lansdown and the low-cost model of flat-fee platforms — offering a broad investment range at percentage-based fees, with important caps for shares and ETF investors.

The capped fee advantage

The key feature of AJ Bell’s pricing is the monthly cap on shares and ETFs in an ISA: £3.50/month, or £42/year. This makes it extremely competitive for investors who hold primarily ETFs or shares rather than funds.

Funds are charged at 0.25% with no cap, which is cheaper than HL but more expensive than Vanguard or InvestEngine for passive investing.

Who is AJ Bell best for?

Verdict

AJ Bell is a strong choice for ETF investors where the £42/year cap significantly undercuts both HL and percentage-based alternatives. For funds investors, compare against Vanguard and ii depending on portfolio size.
