Apply for your Cash-ISA account

Easy steps to the Cash ISA account

Apply online for the Cash ISA

If you don't already bank with us you will also need to have an instant access savings or current account with us. We need this to receive any deposits which may accidentally exceed your annual ISA allowance. You can apply for this at the end of the Cash ISA application.
Complete paperwork

If you already bank online with us, your Cash ISA should be opened immediately.

If you are new to NatWest, we will send your paperwork in the next few days. We’ll also ask you to send identification documents. Once we’ve received these documents, we’ll check them and return them to you. And that’s it. Your Cash ISA is now open and ready to use.
Transfer other ISAs

If you want to transfer another cash ISA to us, once your Cash ISA is open, complete the ISA Transfer form, print it, and send it to: Central Tax Unit, 9th Floor, 1 Hardman Boulevard, Manchester, M3 3AQ and we’ll arrange for the transfer to be completed.
