How this log is kept
Fees are checked against each platform's own help and policy pages. When something changes, the calculator is updated, the change is added here with its date, and the "fees checked" date across the site moves on. Platform names in the table link to the fee calculator for that site.
Spotted a change we've missed?
Platforms don't always announce fee changes loudly. If you've seen one that isn't here, get in touch and it'll be checked and added.
