"Agency Workers policy

We use only specified, reputable employment agencies to source labour and always verifies the practices of any new agency before accepting temporary workers from them. Having used agencies to source short term labour over this past year, we ensured that the external partner was suitably vetted in advance and that all employees had a Right to Work in the UK before being assigned to work within our business."
