As you’ll be getting new card details and a new account number and sort code, you’ll need to update any recurring payments you have going into or out of your account (i.e. subscriptions to things like Netflix or Spotify). You’ll also need to make sure that anyone that has your old account details saved deletes them, as any payments made to this account will not go through.
You’ll also need to activate your new card (virtual or physical) once you have it, and safely and securely dispose of your old physical one.
