Gas Water Heater: Licensed Electrical Worker
Gas Water Heater Licensed Electrical Worker
What EMA LEW supervision means at Homeone — and why the electrical safety of your gas heater installation is not an afterthought.
What is an EMA Licensed Electrical Worker?
A Licensed Electrical Worker (LEW) is a professional licensed by the Energy Market Authority (EMA) to carry out or supervise electrical installation works. Under the Electricity Act, electrical works that affect safety must be carried out or supervised by a licensed professional.
On a gas water heater replacement, the LEW is responsible for ensuring that the equipotential bonding (S/N 9) is correctly installed on both the metal gas pipe and the metal water pipe, that the electrical connections to the heater are safe, and that the installation complies with SS638:2018.

EMA Licensed Electrical Worker on every job — bonded pipes, safe installation, SS638:2018 compliant.
💬 Most gas heater installers don't have a Licensed Electrical Worker. Homeone does.
How supervision works at Homeone
Homeone’s LEW is not an external consultant who signs paperwork. The LEW is a Homeone employee who built the system the technicians operate within.
The architect of the system
Trained the original team. The LEW trained Homeone’s first batch of technicians 8 years ago. Every technician who has joined since has been trained to the same standard, under the same programme.
Updates the SOP when regulations change. When EMA updates regulations or issues new guidance, the LEW organises briefings for all technicians. Homeone’s Standard Operating Procedure is updated to reflect the change. The technicians do not interpret regulations themselves — they follow a procedure that has already been interpreted and verified by the licensed professional.
Annual refresher course. Every year, a refresher course is conducted to ensure no policy is misinterpreted, no procedure has drifted, and every technician is current on the latest requirements.
Available for escalation. If a technician encounters a situation outside the standard scope — an unusual installation, a regulatory question, an unexpected finding — the LEW is available for consultation and guidance.
Systematic documentation — more pairs of eyes than one person on site
Every job at Homeone is photographed systematically. The photos document every stage of the work — before, during, and after. This documentation is kept permanently for future reference.
The documentation is reviewed by multiple people: the Compliance Manager reviews every job in detail from the office, the LEW reviews the documentation and endorses the work, and the operations team monitors for patterns or deviations across all jobs.
This is more oversight than a single licensed professional standing on site could provide. One person on site sees one job in real time, misses what they miss, and leaves no record of what they observed. Homeone’s model puts multiple reviewers on every job, each looking from a different angle, with a permanent photographic record.
On-site presence vs systematic supervision
One licensed professional on site: watches one job, sees what they see, misses what they miss, leaves no record.
Homeone's model: every job photographed, multiple reviewers, permanent record, licensed professional reviews documentation and endorses — trained the team, wrote the SOP, conducts annual refresher.
The certificate the licensed professional signs is not approval of one job. It is endorsement of a system they built and maintain.
Why most competitors don’t have a LEW
Gas heater installers are gas specialists. Most do not have an EMA Licensed Electrical Worker on their team. The electrical work — equipotential bonding, electrical connections, isolator assessment — is either skipped entirely or done without licensed supervision.
This is why equipotential bonding is the most commonly missing safety feature on existing installations. Most installers do not have the licensed capability to install it, so they simply don’t. The customer’s metal pipes remain unbonded — an invisible electrical hazard on the aircon ledge.
Electricity Act, Section 83(3)
Any person who, by rash or negligent act or omission in respect of any electrical installation, causes hurt to any person or damage to any property shall be guilty of an offence and liable on conviction to a fine not exceeding $10,000 or imprisonment for a term not exceeding 3 years, or both.
Why the charge is $0.00
LEW supervision is not a separate service. It is embedded in every gas water heater replacement Homeone performs. The cost of employing the LEW and maintaining the supervision system is built into the overall package price.
The bottom line
Homeone’s LEW is not someone brought in to sign off on bonding work. The LEW trained the technicians on electrical safety procedures, updates the SOP when EMA regulations change, and conducts annual refresher courses. Every job is documented and reviewed.
Most gas heater installers do not have a Licensed Electrical Worker. Homeone does. That is why your metal pipes are bonded and your aircon ledge is electrically safe.
