When a prospective worker gives you their relevant documents to prove that they have the right to work in the UK, you must keep a record of these documents. You must do this by either photocopying them or scanning and saving them electronically on a non-rewritable disk - eg CD-R or DVD-R.
With passports and travel documents, you must copy:
You should copy other documents in their entirety.
Keep copies of the documents until two years after the worker's employment ends. Having a record of every copied document will help you establish a statutory excuse if the UK Border Agency (UKBA) detects anyone working illegally for you.
If you lose any records, the UKBA may look at your normal recruitment procedures when considering if you have established a statutory excuse, eg if you have a consistent practice of copying documents for each worker.
You should not retain a person's original documents, except for the purpose of copying them. The only exceptions are:
You must not keep a potential worker's original documents for more than a day. If you deliberately keep, or retain without consent, a person's passport or other original documents belonging to them, you may be guilty of an offence.
