If you have checked an employee’s right to work before their employment began, you don’t need to repeat your check.
If however you have never checked an employee’s right to work, it is recommended that you do this now.
If right to work checks aren’t carried out before employment begins and the employee is found not to have the right to work, the employer is at risk of being fined up to £60,000 per illegal worker. This risk remains even if the right to work check is carried out after the employee begins work however it is better to carry out a late check than none at all as this will identify any concerns and give you the opportunity to resolve this or take action before the Home Office does.
