Water Bills in WA Rentals: Who Pays Usage and Service Charges?

When a rental property changes hands between owners, tenants or managing agents, utility accounts can become confusing. A water bill can contain both consumption and service charges; an electricity account may be in the tenant’s name or the owner’s; and two dwellings on one site may not have the same metering arrangement. Before passing any cost on, landlords need to know what the charge is, who is responsible under the tenancy agreement and how the amount is supported.

This practical guide is for ordinary residential rental properties in Mandurah, the Peel region and wider Western Australia. It draws on current WA Consumer Protection guidance on rental bills and Water Corporation’s residential tenant-billing information. Commercial leases and residential parks can have different rules.

Water usage and water service charges are not the same bill item

For a typical WA residential tenancy, the tenant pays for their water consumption, while the landlord pays water rates and service charges. Water Corporation’s regular bill generally contains both components. An owner should therefore not forward the entire account and assume every line is payable by the tenant. The tenancy agreement, metering details and how bills are delivered still need to be checked.

Water Corporation also offers tenant billing, in which a tenant can receive and pay their water-use bill directly. This arrangement requires the owner or property manager’s authorisation and does not remove the need to keep the property account and service-charge responsibilities clear. If an account is overdue, Water Corporation says the owner or managing agent may still receive the overdue notice.

There is a 30-day deadline when a landlord passes on utility consumption

Where the landlord or strata company receives a utility bill and then charges the tenant for their consumption, WA Consumer Protection states that written notice must be given to the tenant within 30 days after the bill is received. Missing that deadline means the tenant is not required to pay that charge.

That notice needs to identify the total consumption charge and the relevant information used to calculate it. For a separately metered service, include meter readings and the price per metered unit. For a service without a separate meter, include the calculation agreed in the tenancy agreement. Consumer Protection also requires the amount of any GST payable on the tenant’s part to be identified. Retain the original provider bill and the date it was received; the billing record should be capable of explaining the amount, not simply demanding payment.

This is a reason to establish who receives utility accounts as soon as management begins. If a bill remains in the former owner’s or previous agent’s inbox, the property manager may not see it in time to send a compliant notice.

Shared meters and dual residences need an agreed calculation

Do not assume two separate street addresses automatically mean two independent meters. A property can have a shared main meter, individual submetering, or a different service arrangement for each utility. The WA residential tenancy guidance says that, where a home shares a meter, the agreement must explain how the tenant’s consumption is calculated. An unsupported equal split is not a substitute for the agreed method.

Water Corporation explains the difference between a shared meter and a submeter. A Water Corporation submeter may be read and billed by the provider; a private submeter generally requires the responsible party to record the readings. That distinction should be checked before promising direct billing.

Beshay Realty’s published leased campaigns include 4 Kombu Way and 4A Kombu Way, South Yunderup. They are real examples of why property-specific questions matter when leasing nearby residences; they are not evidence of any particular meter configuration, utility cost or billing practice at those addresses.

Electricity and gas: check whose name is on the account

When a residential tenant establishes their own electricity or gas account, they will usually pay the supplier’s applicable connection and consumption costs. If the utility account instead remains in the landlord’s name, Consumer Protection says the landlord cannot add supply or administration charges to the tenant’s consumption bill. With a submeter, the tenant should be charged only their measured consumption. With a shared meter, the tenancy agreement should set out how that consumption is calculated.

Ask early whether electricity is supplied through a direct retailer account, an owner account or a submeter arrangement. The same question should be asked separately for gas and water: one property can have different billing methods for all three services. Record any arrangements in the tenancy agreement rather than relying on a verbal understanding at the start of a lease.

At the beginning and end of a tenancy, record the readings

WA Consumer Protection recommends organising a water meter reading at the start and end of a tenancy, with a record in the property condition report or the rental agreement. Water Corporation describes the option of a special meter reading when a tenancy changes outside the ordinary bill cycle.

The practical objective is to separate usage before occupancy, during the tenancy and after vacating. If a rental is empty between tenancies, do not automatically allocate that period’s consumption to the next tenant. At finalisation, follow the applicable notice and evidence requirements rather than estimating consumption from an arbitrary settlement or vacate date.

Who deals with leaks and unexpected usage?

An unusually high water-use figure should trigger investigation, not an automatic invoice to the tenant. Ask whether there is a leaking toilet, burst irrigation fitting or another fault, record when it was reported and arrange inspection or repair where appropriate. Water Corporation’s tenant guidance directs tenants to report leaks promptly to the owner or property manager and explains the owner’s role in repair and water-loss costs. Particular circumstances should be assessed before attributing disputed consumption.

A sensible utility handover for Mandurah and Peel landlords

• Before the tenant moves in: identify the provider for each service, confirm any separate or shared meters, document initial readings and record how charges will be calculated under the tenancy agreement.
• When management starts or changes: confirm which owner or agent receives each bill, whether direct tenant water billing has been authorised, and whether earlier periods have outstanding invoices.
• When an account arrives: distinguish usage from owner service charges; check the billing dates, readings, any shared-meter formula and the 30-day written-notice requirement.
• At vacate: arrange and document final readings where appropriate, reconcile the final usage period and make sure provider accounts and tenant communications reflect the handover.

These checks are worth making whether the property is in Halls Head, Lakelands, South Yunderup, Secret Harbour or Rockingham. The correct process depends on the property’s actual services, the residential tenancy agreement and the provider’s billing arrangement—not a standard assumption applied to every house.
