Which UK trading app is best?
For buying shares and ETFs to hold:Trading 212 — free dealing, no platform fee, an in-house ISA and a SIPP, and a 0.15% conversion fee that is five times lower than its nearest commission-free rival.
For a full-service investing app:Hargreaves Lansdown or AJ Bell, where you pay a percentage but get research, a wider fund range and a mature pension product.
For active and leveraged trading: a dedicated platform rather than a general app — Pepperstone or Capital.com for FX and indices, where pricing is published per instrument and execution is built for it.
For copy trading:eToro, which is genuinely the only one of these with live copy trading. You pay for it in a 0.75% conversion fee.
The three kinds of app, and why the distinction matters
The categories overlap on the app store and not in reality. Several brands offer all three from one login, and the interface rarely makes clear which one you are using. Buying a share and buying a CFD on the same share look almost identical on screen and behave completely differently — one you own, the other accrues financing daily and is capped at 5:1 leverage by FCA rule.
Table 1 — Three products sold as one category
| Type | What you pay | What you get | Examples |
|---|---|---|---|
| Commission-free investing | Conversion fee; no dealing or platform charge | Real shares and ETFs, ISA, sometimes a SIPP | Trading 212, eToro |
| Full-service investing | Percentage custody fee plus per-deal commission | Funds, research, mature pension products | Hargreaves Lansdown, AJ Bell |
| Active trading | Spread and commission per trade | Leverage, short selling, FX and indices | Pepperstone, Capital.com, IG, CMC |
What the commission-free apps actually cost
Where the money actually goes. Neither app charges you to trade, so conversion is the revenue. On £10,000 of US shares bought and later sold, Trading 212’s 0.15% costs about £30 across both legs; eToro’s 0.75% costs about £150, plus a further charge on every dividend along the way. That is the comparison worth making, and it appears in no headline.
