Help with common questions
- Signing in or account trouble — write to us from the work email you registered with, so we can find your account.
- A result looks wrong — tell us the module and the figures you entered (amount, rate, tenure). Results are estimates; your bank's approved systems give the final figures.
- Ideas and feature requests — we'd love to hear what would make your day as an RM easier.
- Deleting your account — follow the steps on the delete account page.
- How we handle your data — see our privacy policy.
