The law distinguishes between urgent (emergency) repairs and those which are not so urgent.
Urgent repairs are:
a burst water service or a serious water service leak
a blocked or broken toilet
a serious roof leak
a gas leak
a dangerous electrical fault
flooding or serious flood damage
serious storm or fire damage
a failure or breakdown of the gas, electricity or water supply to the premises
a failure or breakdown of the hot water service
a failure or breakdown of the stove or oven
a failure or breakdown of a heater or air-conditioner
a fault or damage which makes the premises unsafe or insecure.
If urgent repairs are needed you should notify the landlord or agent right away. The landlord or agent must arrange for the repairs to be done as soon as possible. If you cannot reach them, check your tenancy agreement for the details of a nominated tradesperson to contact.
