The lessor nominates a person to arrange or make emergency repairs, stating in the agreement or a written notice the repairer's name and telephone number and whether the repairer is the tenant's first point of contact, and notifies any change in writing; this is not needed where the lessor has given its own telephone number and arranges emergency repairs itself.
