You can join us on a quick video call, where we can guide you through the process and we can even check your ID and recent utility bill, on the call - so, you don't even need to leave your home or scan any documents.

If getting into town isn’t a problem for you, then you can sign up in person at our high street store and discuss your requirements with our retail team.

Still have questions or not sure what’s best for you? Then use our call back feature and we’ll get back to you at a time that’s convenient to you.
We appreciate that life can be busy and getting into town can be a hassle for some. We’re here to arrange a video call, so we can take you through the sign-up process in the comfort of your own home. Once you select your preferences below, we’ll be in touch to confirm the date and time. You’ll need a working camera so we can confirm your identity.
