Important points to note:  

It’s important to note that some of our roles are subject to pre-employment vetting (which may include DBS checks for successful candidates). If required, you’ll be informed and provided with information about vetting during the recruitment process and we encourage you to complete any vetting documents quickly to avoid delays. Any DBS checks required will be carried out by a third-party registered body and financial probity checks may also be required for some of our roles.

We also recommend that you apply as soon as possible as vacancies can close early if we see a high number of applicants.  

We want all of our Partners to have a good work-life balance and we support flexible working. This might mean flexible or compressed hours, job sharing or shorter hour contracts, where possible. Please discuss this further with the hiring manager during your interview.
