Leases: licences: possession: service occupancy
When it is contended that occupation of a particular property is essential for the performance of the employee’s duties, it must be established that only occupation of that particular property would suffice (Langley v Appleby)
Where an existing employee undertakes new duties and is offered accommodation by the employer provided that he undertakes those duties (the performance of which will be materially assisted by residence in the employer’s accommodation) then the employee is a service occupier and the employer retains possession (Norris v Checksfield)
