Hi @User790
Welcome to the community.
You can change the direct debit details for your account by logging in to the EE website > selecting Bills & Payments > Manage Direct Debit > Change Direct Debit and enter the new details.
This applies for a broadband account or the airtime part of a contract. If you have a Flex Pay plan where you pay for the phone separately, please give us a call and one of our guides can update the details for that payment.
There is more on changing the direct debit on our Change your EE Direct Debit date or details page.
