Reviewers consistently rate the app as easy to use and good value, and many mention the competitive interest paid on uninvested cash.
The most common criticisms are slow identity verification for new accounts and support that can take time to respond.
Read Trading 212 reviews on TrustpilotReviewers repeatedly mention that the platform is easy to use and communication is clear. AJ Bell has been Which? Recommended for eight years running.
Occasional gripes about transfer times and the dealing charge compared with app-only rivals.
Read AJ Bell reviews on TrustpilotTrading 212 built its name on removing fees. There is no platform fee, no dealing commission and no account charge on its ISA or SIPP. The only cost most investors pay is a 0.15% currency conversion fee when buying shares priced in dollars or euros.
The trade-off is scope. You can hold shares and ETFs but not traditional funds, and support is app-based. For an investor who wants a global tracker ETF inside an ISA at close to zero cost, it is very hard to beat on price.
AJ 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.
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.
