No Breach of Repairing Obligation Until Notice and Reasonable Time (Within Demise)

The landlord's obligation in relation to property in the possession of the tenant is not an undertaking to prevent them ever getting out of repair during the continuance of the tenancy; it is an undertaking to do work of repair on the premises from time to time as and when they have become out of repair. Thus the landlord is not liable for breach of covenant as soon as the premises are in fact out of repair. Until the landlord has notice of the disrepair no breach arises; nor does any breach arise thereafter if the landlord then carries out the necessary work of repair with reasonable expedition.
