What do you mean by Service Engineer. Is he your employee engaged with Contract of employment or he is coming from the Manufacturer, only for servicing the equipment you owned with Contract for employment. If he is your employee then obviously you must comply with all the statutory obligations and on demand you must provide the details being asked by your Principal Employer.
