Because you're a new customer, you'll need to send us two forms of ID. Don't worry, you can do this easily now. We need one form of photo I.D and one form of address I.D. The upload file encrpyts your data making it safe to send electronically, but If you prefer, you can send us a copy of your I.D in the post to the address on your application confirmation email.
If you're not sure what I.D you need then take a quick look at our I.D Guide.
