To deposit money into your current account, you'll have to make a bank transfer. The most common way to complete a bank transfer is via your bank's mobile app or website.
To deposit money into your account, you'll need to input your eight-digit account number and six-digit sort code, along with the name you registered the account under. The combination of your sort code and account number should be unique to you and is what is used by the bank to know which account to add money to.
You then need to input the amount of money you want to deposit. Depositing money into your current account should be instant, but it could take up to three working days. If you want to deposit cash, you can do this at your local bank branch over the counter or use a self-service machine.
