Licensed Gas Service Worker
Most gas heater installers do not have a Licensed Plumber. Homeone does.
A Licensed Gas Service Worker (LGSW) is a gas worker registered with the Energy Market Authority and legally authorised to carry out regulated gas work in Singapore. At Homeone, the LGSW is not just the person who signs the Certificate of Gas Safety — the LGSW trained the team, wrote the standard operating procedures, and maintains the standard every technician works to. The certificate is an endorsement of a system, not just a signature on a form.
How Every Job Is Reviewed Before the Certificate Is Issued
The job is first reviewed by a manager against the documented scope and site conditions before it reaches the LGSW.
The LGSW reviews the completed work against regulatory requirements and Homeone's SOPs — independently of the technician who carried it out.
The Certificate of Gas Safety is issued only after both reviews are complete. The LGSW's endorsement carries personal legal accountability.
What the LGSW Does Within Homeone's System
The LGSW trains Homeone's field technicians on correct gas-side installation and compliance procedures, continuously updated as regulations and SOPs change.
Standard Operating Procedures for all gas-related work are written and owned by the LGSW — not assembled from memory on the day of each job.
When EMA updates its requirements, the LGSW translates those changes into internal SOPs. Regulatory shifts do not get missed because one technician on one job was unaware of them.
The LGSW licence is tied to ongoing compliance with EMA requirements. This creates an external accountability loop that keeps Homeone's internal standards current.
How the Models Compare
Carrying out regulated gas work without a Licensed Gas Service Worker is an offence under Singapore's Gas Supply Regulations. The penalty is a fine of up to SGD 5,000. This applies to the person who signed off the work. If your installer does not have an LGSW, the gas-side work on your heater was not legally certified — regardless of what paperwork was handed to you.
The Certificate of Gas Safety you receive from Homeone is signed by an LGSW who trained the team, wrote the SOP, and reviewed the job — not just someone who showed up to stamp a form. The certificate is an endorsement of a system that exists before, during, and after your installation.
