It is a legal requirement that all UK employers check the eligibility of employees to work in the UK.
Under the Conduct Regulations both agencies and employment businesses are obliged to confirm the identity of all work seekers before introduction or supply. The DTI has not provided any definitive list of documents that must be checked by employment agencies and businesses for these purposes, but has confirmed such a check would be satisfied by having sight of a copy of driving licence, passport, ID card, National Insurance document or a utility bill.
At Wizard Recruitment, we check the eligibility of all candidates that we recommend to employers. This is part of the service that we offer to all clients.
The employer must still make their own eligibility checks, but due to Wizard's initial check, this should be a formality.
