Trading 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.
Prosper's pitch is the cheapest total cost of ownership in the UK: no platform fee, no dealing fees, and refunded fund fees on a list of mainstream index funds. For a straightforward global tracker in an ISA or SIPP, the all-in cost really can be zero.
The counterweight is maturity. It is a young platform with a small (if very positive) review base and no individual shares. If that trade-off suits you, the price is unbeatable.
It depends on what you hold and how often you trade. Trading 212's platform fee is £0, against £0 at Prosper. On dealing, Trading 212 charges £0 commission for shares and eTFs only, £0 commission for funds, while Prosper charges not applicable (funds and ETFs) for shares and free for funds. Fees verified July 2026.

Yes. UK platforms accept ISA and SIPP transfers in, and you start the transfer with the receiving provider rather than the one you are leaving. Trading 212 charges free on withdrawals and Prosper charges free. Transfer as cash and you are out of the market while it settles; transfer in specie and you keep your holdings but it takes longer.
Trading 212 or Prosper, the account is the easy part. What decides when you can retire is how much goes in and for how long. Delphina works that out from what you already hold and what you pay in each month.
