At Nationwide we offer hybrid working wherever possible.

If you’re based at our Glasgow office, this will apply from 1 April 2027 and ahead of that there will be a need to regularly connect with colleagues for collaboration events. If your application is successful, your hiring manager will provide further details on how this works.
