If the hot water at your rental property has stopped working, the landlord is usually responsible for fixing it. Under Australian residential tenancy law, hot water is classified as an essential service, and landlords must maintain and repair all fixed appliances, including the hot water system, throughout the tenancy. That covers both repairs and full replacement when a repair is no longer viable.
The answer can vary depending on what caused the breakdown, your lease agreement, and the state you’re renting in. Below, we cover who pays, what counts as urgent, and what tenants and landlords can do when things stall.
Every state and territory in Australia has a Residential Tenancies Act (or equivalent) that places a clear obligation on landlords. The landlord must provide rental premises that are fit for habitation, maintained in a reasonable state of repair, and in compliance with building codes and health and safety laws. That includes the gas supply, electricity, plumbing, and hot water.
This cannot be contracted out of in the tenancy agreement. Even if a landlord claims the lease agreement doesn’t cover hot water maintenance, the law overrides that. The landlord is responsible for keeping the property and its fixtures, including smoke alarms, air conditioning, and cooking appliances, in working order throughout the tenancy.
“Reasonable repair” is measured against the age and condition of the property. A landlord doesn’t have to install a brand new system just because the old one is showing its age. But if the hot water system has failed and repair isn’t practical, replacement becomes the landlord’s responsibility.
A complete loss of hot water is classified as an urgent repair in every Australian state and territory. Under residential tenancies legislation, urgent repairs include the failure or breakdown of any essential service for hot water, gas, electricity, or water supply. A burst water pipe, a gas fault connected to the unit, or an electrical fault on the hot water system all fall into this category.
Most landlords are expected to respond within 24 to 48 hours for urgent matters. Beyond that, tenants have documented self-help remedies available to them.
Not every hot water issue counts as urgent, though:
| Urgent | Not Urgent |
| No hot water at all | Slightly reduced water temperature |
| Gas fault connected to the unit | Ageing system still functioning |
| Electrical fault on the hot water system | Minor pressure drop at the tap |
| Water leaking from the system or a burst water pipe | Rust-coloured cold water from an old tank |
This is the grey area that causes the most disputes. If a hot water system breaks down due to fair wear and tear, that’s the landlord’s cost. If damage was caused by the tenant’s misuse, negligence, or deliberate action, the tenant is responsible.
Fair wear and tear includes a thermostat failure in an ageing unit, a heating element burning out after years of use, or general end-of-life failure. The tenant’s responsibility kicks in when damage is caused by misuse, such as tampering with gas connections, failing to report a known leak that caused further damage to the premises, or ignoring maintenance access requests.
The burden of proof sits with the landlord. The ongoing condition report is the most important document for both parties. If the system was already old and deteriorating when the tenancy started, it’s very hard for a landlord to argue that the tenant is at fault.
The core principle is consistent across Australia. Landlords are responsible for urgent repairs to essential services, and hot water is an essential service in every jurisdiction. The escalation pathways, self-repair caps, and dispute resolution bodies do differ, though:
| State | Governing Act | Urgent Response | Dispute Tribunal | Tenant Self-Repair Cap* |
| QLD | Residential Tenancies and Rooming Accommodation Act 2008 | As soon as practicable | QCAT | Up to 4 weeks’ rent |
| NSW | Residential Tenancies Act 2010 | ASAP (urgent) | NCAT | Up to $1,000 |
| VIC | Residential Tenancies Act 1997 | Immediately | RDRV / VCAT | Up to $2,500 |
| WA | Residential Tenancies Act 1987 | 24 hrs (essential services) | Magistrates Court | Reasonable costs (no fixed cap) |
| SA | Residential Tenancies Act 1995 | As soon as practicable | SACAT | Reasonable costs (no fixed cap) |
| TAS | Residential Tenancy Act 1997 | As soon as practicable | Magistrates Court | Restore essential service only |
| ACT | Residential Tenancies Act 1997 | Within 24 hrs | ACAT | Check ACT tenancy authority |
| NT | Residential Tenancies Act 1999 | As soon as practicable | NTCAT | Check NT Consumer Affairs |
*The self-repair cap is the maximum a tenant can spend on emergency repairs without prior landlord approval, after making reasonable attempts to contact the landlord or agent. Figures current as at May 2026. Check your state’s tenancy authority for the latest amounts.
In NSW, if your landlord is not fixing the problem, NSW Fair Trading can investigate and issue a rectification order with a completion date. It’s an escalation option worth knowing about.
If you have no hot water tonight, this is the process to follow:
A landlord’s obligation doesn’t end at repair. If the hot water system has reached the end of its life and fixing it is no longer viable, the landlord must replace it. There is no legal basis for delaying indefinitely on cost grounds.
Approximate lifespan benchmarks by system type:
| System Type | Approximate Lifespan |
| Electric storage | 8 to 12 years |
| Gas storage | 8 to 12 years |
| Continuous flow (gas) | 15 to 20 years |
| Heat pump | 10 to 15 years |
| Solar | 15 to 20 years |
If your system is approaching or past these benchmarks, a breakdown is more likely to be an end-of-life failure than something that can be patched. For landlords, proactive replacement often costs less than repeated emergency call-outs and rent reduction claims.
Hot water sits within a broader set of maintenance obligations under tenancy law. Alongside hot water, landlords are also responsible for:
Knowing where hot water fits in this list helps both landlords and tenants stay on top of their obligations.
Hot water is an essential service, and the landlord is responsible for maintaining and replacing the hot water system in a rental property when it fails through normal use. Every state classifies a failed hot water system as an urgent repair, with response times generally sitting at 24 to 48 hours. If your landlord isn’t acting, you can escalate through your state tribunal.
