The Home Office Employer Checking Service is the enquiry and advice service that employers are required to contact in certain circumstances to check whether a person is allowed to work in the UK and if so, the nature of any restrictions on that person’s right to do so.
If you use the Employer Checking Service, you will only establish a statutory excuse if you are issued with a Positive Verification Notice confirming that the named person is allowed to carry out the type of work in question. A Positive Verification Notice will provide you with a statutory excuse for six months from the date specified in the notice. You must therefore undertake a further check before this expires, if the statutory excuse is to be retained.
