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.
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.
It depends on what you hold and how often you trade. Vanguard's platform fee is £4/month minimum below £32k; 0.15% above £32k, capped at £375/year, against 0.35% up to £250k (0.20% above); £90/year flat if under £25k without a regular savings plan at Fidelity. On dealing, Vanguard charges not available (funds and Vanguard ETFs only) for shares and free for funds, while Fidelity charges £7.50 per online trade 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. Vanguard 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.
Vanguard 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.
