ISA Costcustody plus dealing, not the headline rate

Vanguard UK: what the ISA actually costs

Vanguard UK is not the cheapest at any pot size on this site. That is not a verdict on the platform — only on its published charges against the others', at 12 trades a year.

Shares and etfs

Vanguard's ISA holds Vanguard's own funds and ETFs only, so it cannot be costed as a general share-dealing account.

Every figure assumes 12 trades a year of £1,000 each, inside a stocks and shares ISA. It excludes Stamp duty at 0.5% on UK share purchases, the £1 PTM levy on orders over £10,000, fund manager charges (the OCF), and any foreign-exchange fee — every one of those is charged by someone other than the platform and is the same wherever you hold the money.

Where this platform wins

Charges read 18 August 2026 from Vanguard UK's own pricing page. No FX fee is published because you cannot buy individual international shares — only Vanguard's own GBP funds and ETFs. The £4/month minimum makes small pots proportionally expensive: on £5,000 that is roughly 1% a year.

Charges read 19 August 2026 from each platform's own pricing page. Platforms reprice with little notice, and nothing here is advice — it is arithmetic on published charges.
