Is it possible to add my wifes name to the account?
All that we need is some authorisation from your partner that they’re happy to be included on the statements.
Easiest way is for you to call in and then for you to hand the phone over to them so they can to confirm.
Alternatively, you can email in with their email address cc’ed in the email. The email should include a detail asking for them to confirm that they’re happy to be included.
