Does an employer have the right to insist on medical checks for all new employees?

An employer can insist that all new employees undergo a medical check provided that the check is designed to ensure that they are fit to perform a particular job. If the medical standard is set too high in relation to the job, there is a risk that it will not be justifiable under the Human Rights Act 1998.

There is (with a small number of exceptions) no legal requirement for employers to require prospective employees to undergo medical examinations, but if the employer has made the job offer conditional on a satisfactory medical examination, it is within its rights to withdraw the offer if the job applicant refuses to take a medical examination.
