Read AJ Bell reviews on TrustpilotLong-term investors praise the low fund costs and the simplicity of LifeStrategy portfolios.
The £4 minimum monthly fee frustrated smaller investors when it landed, and some reviews mention slow customer service.
Read Vanguard reviews on TrustpilotAJ Bell sits in the sweet spot between cheap app-only brokers and expensive full-service platforms. You get funds, shares, ETFs, a well-regarded SIPP and a Lifetime ISA, with caps that keep costs sensible for share investors.
It suits people who want one account for everything, particularly ETF investors who benefit from the £3.50 monthly cap in an ISA. Fund-heavy portfolios above six figures should compare the 0.25% fee against a flat-fee platform like Interactive Investor.
Vanguard UK is the default answer for one-fund index investing. If your plan is a LifeStrategy or FTSE Global All Cap fund and nothing else, the combination of cheap funds and a capped 0.15% platform fee is excellent, especially above £32,000.
Below £32,000 the £4 monthly minimum changes the maths, and a free platform like Trading 212 or Prosper holding a similar Vanguard ETF can work out cheaper. You also cannot hold individual shares or other fund managers' products.
A 0.2% fee difference is worth optimising. Knowing whether you are saving enough in the first place is worth far more. Delphina models your pensions, ISAs and investments and tells you where you actually stand.
