Add money to your account from another bank account by using your Starling account number and sort code. Starling is part of the Faster Payments network, so the money usually arrives in your account instantly.
Alternatively, you can also choose to make Starling your main bank account by using the Current Account Switch Service in app. This moves your balance, direct debits and any other regular payments across to Starling from your old bank in 7 working days.
