PUB licensed plumber in Singapore — what it means, and how to verify ours
Anyone can print "licensed" on a van. Here's what a PUB plumber licence actually covers, how to check one in a minute, and what to ask for when your MCST or contractor wants documentation.
Plumbing in Singapore sits inside a licensing framework run by PUB, the national water agency. Regulated plumbing works are required to be carried out by a licensed plumber — which is why building owners, MCSTs, contractors and developers ask for a licence number before work begins.
Our licensed plumber is Lam Kien Choon, licence WS16882018. You don't have to take our word for it: the licence can be checked through PUB's own resources at pub.gov.sg. Our company, Alpha & Omega Trinity Pte Ltd, also holds BCA ME12 registration for plumbing and sanitary works.
What this means for your job
- Regulated works are supervised properly — not handed to whoever is free that day.
- You can verify rather than trust — one licence number, one check.
- Documentation requests get answered — MCSTs and contractors often need it; tell us and we'll cover what your scope requires.
- Compliant materials — used on plumbing works where the regime applies.
How to check any plumber's licence
- Ask for the licensed plumber's full name and licence number — a company registration alone isn't a plumber licence.
- Check it against PUB's published resources at pub.gov.sg.
- Make sure the name on the licence is the person actually responsible for the works.
