In Perth, Western Australia, installing a hot water system is not a job for just one trade. The answer depends on the type of system being installed. A licensed plumber is responsible for connecting the water supply, valves, and ensuring pressure compliance. If the system is gas-powered, a licensed gas fitter is legally required to connect the gas line. For electric storage or heat pump systems, a licensed electrician must handle the electrical wiring and circuit protection. In many Perth homes, both trades are required to complete the installation safely and legally. Using the correct licensed professionals ensures the system meets WA plumbing and electrical regulations, protects your warranty, and prevents safety risks. If you are unsure which trade is needed, a professional company like Marchant Plumbing and Gas can coordinate the entire process for you.

Who Is Legally Allowed to Install a Hot Water System in Perth?
In Western Australia, strict licensing laws apply to hot water installations. A licensed plumber must install and connect the water supply to any hot water system. If the unit is gas-powered, it must be connected by a licensed gas fitter, which is often the same plumber if properly endorsed. For electric storage systems, a licensed electrician is required to complete the electrical connections safely. Compliance certificates are mandatory for plumbing and gas work, confirming the installation meets WA standards. These certificates protect homeowners and are often required for insurance and warranty validation. Using unlicensed installers can void manufacturer warranties, create safety hazards, and breach WA regulations. Perth homeowners should always confirm licensing before work begins. Choosing a fully qualified provider ensures the system is installed legally, safely, and in compliance with all state requirements.
When Do You Need Both a Plumber and an Electrician for Installation?
Many installations in Perth require both trades. Electric storage systems need plumbing for water connections and electrical wiring for power supply. Heat pump systems often require a dedicated electrical circuit or switchboard upgrade, making an electrician essential. The plumber handles valves, pipework, pressure relief systems, and water compliance, while the electrician manages wiring, safety switches, and circuit protection. Gas systems may require only a licensed plumber with gas endorsement, but hybrid systems typically involve both professionals. Coordinating two trades separately can delay installation and increase costs. That is why many Perth companies manage both roles together for a seamless installation. Working with a provider that understands the split responsibilities ensures the system is installed efficiently, legally, and without compliance issues. Always confirm that both plumbing and electrical requirements are covered before scheduling installation.
