If you update any of your personal details, the changes will be applied to all accounts you hold with Marcus. But if you have a joint account, the changes you make won't affect your joint account holder. So for example, if you update your home address, and you share that address with your joint account holder, they'll need to log into their own account to update their address there.
Change of address
You can update your address online. Log into your account, head to your profile in the top right corner, and click on the edit icon underneath contact information.
Update your email address or phone number
If you want to update your email address or phone number, give our Customer Care Team a call on 0800 085 6789 or +44 203 901 3353 if you’re calling from abroad. Lines are open from 8am to 8pm, Monday to Friday (excluding bank holidays).
Changing your name
To change your name, please download our change of name form. Send this to us either online or in the post, along with any supporting documents we ask for on the form. You can also request a copy of the form in the post by giving us a call.
Please note: We’re expecting we may experience delays in receiving deliveries at the moment, so if you send us something in the post, it may take longer than usual for us to process it.
