A 0.25% yearly fee gap sounds small. On £50,000 over 20 years it is about £5,900 (illustrative). Add your ISA and pension balances to Delphina yourself and see what your charges cost by retirement and whether you're on track.
See what my fees costIllustrative: £50,000, 5% a year growth before charges, 0.25% vs 0.50% a year in charges, no further contributions. Not a recommendation of Trading 212 or Fidelity. Delphina is guidance, not financial advice.
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.
Fidelity is a solid full-service choice for fund investors. Fund dealing is free, the ETF and share service fee is capped at £90 a year, and the guidance content is some of the best of the big platforms.
Costs are less friendly if you trade shares often or hold a small account without a regular savings plan. Compare it against AJ Bell if you want similar breadth with lower dealing charges.
For shares and ETFs, Trading 212 charges no platform fee and no commission. Fidelity's fee on shares, ETFs and investment trusts in an ISA is capped at £7.50 a month (£90 a year). It also charges £7.50 per online trade, or £1.50 through a regular savings plan.
On £50,000 in shares and ETFs in an ISA, that is £0 a year at Trading 212 and £90 at Fidelity before dealing. Twelve monthly purchases through Fidelity's regular savings plan would add £18. Twelve one-off online trades would add £90.
The charge Trading 212 does make is FX: 0.15% on trades in currencies other than sterling. Buying £1,000 of US shares costs £1.50 in FX.
Trading 212 sells shares and ETFs but no funds (OEICs and unit trusts). Fidelity sells funds with no dealing charge. It charges 0.35% a year from £25,000 to £250,000, or a flat £90 a year under £25,000 unless you have a regular savings plan. £50,000 in funds at Fidelity costs £175 a year.
If you transfer a fund-based ISA to Trading 212, the funds have to be sold to cash first, because holdings only move in specie where both platforms hold the same investment. Trading 212 starts the transfer as the receiving provider.
A flexible ISA lets you take money out and put it back in the same tax year without using more of your allowance. Trading 212's ISA is flexible. Fidelity's is not.
Trading 212 tends to suit people building a portfolio of shares and ETFs who want no platform fee and a flexible ISA. Fidelity tends to suit people who hold or want funds, want a Junior ISA next to their own, or have a larger share portfolio where a £90 cap is a known, fixed cost.
It depends on what you hold and how often you trade. Trading 212's platform fee is £0, against 0.35% from £25k to £250k; 0.20% from £250k to £1m; nothing above £1m; £90 a year flat under £25k without a regular savings plan at Fidelity. On dealing, Trading 212 charges £0 commission for shares and eTFs only, £0 commission for funds, while Fidelity charges £7.50 per online trade for shares and free for funds. Fees verified July 2026.
Trading 212 is best for cost-conscious DIY investors who want to keep every fee at zero. Fidelity is best for fund investors who value guidance, tools and phone support. Both are FCA regulated and covered by the FSCS.

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 Fidelity 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 Fidelity, 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.
