Switcher product guide

If your client is a DHLL or E-Mex customer and wants to switch, view our switcher guides and forms.

Our simultaneous Rate switch and Further Advance application process is currently unavailable. We’re sorry for any inconvenience caused.

If you require account specific information prior to creating a switcher application, please ensure you have completed the Third Party Authority Form. The form should then be emailed to SLLand&Deeds@nationwide.co.uk or posted to the address at the bottom of the form.

Be aware - switcher dates

You can switch your client's mortgage up to six weeks before their mortgage deal is ending, although the new rate won't take effect until the current deal expires.

Product switches always take effect from the 1st of the month. Switcher applications must be submitted and accepted, at least five days before this. After this time, the new deal won't apply until the 1st of the following month.

The table below shows the dates that an application can be submitted and accepted, in order to apply from the 1st of the following month.
