Confirming your account application

You'll get an email shortly to let you know we've received your application – it'll also explain what happens next.

We need two pieces of information from you: a completed signature mandate form, and a bank statement for your nominated account.

Please complete our signature mandate form and post it to the address on the form. Make sure the signatory details on the form match those used in your application.

If you don’t have your account number(s) yet, don’t worry – we’ll fill this in for you when you return the form.

As part of the account opening process, we'll try to verify your nominated account electronically. If we can't do this, we'll ask you to email us a bank statement for your chosen nominated account showing your account name, sort code and account number. You should send this as a PDF to BusinessSavings@nationwide.co.uk

Audit authority form

When your auditors ask for the information that we hold on you and/or your accounts we need to have your permission to send this to them. You don't need to fill in the account number as we'll fill this in. Please speak to your auditor first, as you only need to complete this form if your auditor does not use ‘Confirmation’ as an audit platform.
