Thanks to automatic payment forwarding, any Faster Payments sent to your old sort code (23-69-72) and account number will automatically redirect to your new account for up to 3 years. That being said, it would be great to start updating your clients or anyone who sends money to your account as soon as you can.
In-app invoice templates will update automatically; we recommend updating your payment details anywhere else they are displayed, such as external invoice templates or your website.
