The three essential elements of a lease
According to the House of Lords case of Street v Mountford  UKHL 4, a lease is the grant of a right to the exclusive possession of land for a determinate term less than that which the grantor himself has in the land. This definition identifies three essential elements:
- exclusive possession;
- determinate term;
- term less than that of grantor.
Exclusive possession is an essential ingredient of a lease; without exclusive possession there can be no lease. Exclusive possession is the right to use premises to the exclusion of all others, including the landlord himself.
If the occupier has no right to exclusive possession of the premises then his right to use the premises cannot amount to a lease, although it may be some lesser right, such as a licence or possibly an easement. However, the fact that a person had been given exclusive possession is not conclusive proof that he has a lease, for it is also possible to have a licence or certain other rights in land, without exclusive possession.
Although exclusive possession normally gives the tenant the right to exclude everyone else, including the landlord, from the premises, the lease may reserve the right for the landlord to enter the premises on certain occasions, eg, to inspect the state of repair of the property. Such a right must be exercised at reasonable hours and in a reasonable manner and does not prevent the tenant having exclusive possession, though a right for the landlord to come and go as he pleases without the tenant’s permission would have this effect.
Thus in Appah v Parncliffe Investments Ltd  1WLR 1064, in which the ‘landlord’ had reserved the right to come into the premises as and when he chose to empty meters and change linen, the arrangement was held to be a licence, since the occupier did not have exclusive possession.
The commencement of the period must be certain in a lease. Normally, if no mention is made in the agreement, it will be deemed to start immediately (Furness v Bond (1888) 4 TLR 457). If, however, one has only an agreement for a future lease, it will be void unless it is clear at what date the lease is to start, either from an express term in the contract or by inference (Harvey v Pratt  1 WLR 1025).
