What Is a PUB Licensed Plumber?
In Singapore, the Public Utilities Board (PUB) regulates all licensed plumbing works under the Public Utilities (Water Supply) Regulations. A PUB Licensed Plumber has been assessed, trained, and registered to legally perform plumbing installations, repairs, and replacements that connect to the public water supply network.
Not every person who calls themselves a plumber is PUB licensed. Unlicensed plumbing work is illegal in Singapore, voids your building insurance, and can result in enforcement action by PUB.
Why You Must Only Hire a PUB Licensed Plumber
Hiring an unlicensed plumber in Singapore exposes you to serious risks:
Legal liability — Under the Public Utilities Act, plumbing works on PUB water supply systems must be carried out by or under the supervision of a licensed plumber. Non-compliance is an offence.
Insurance void — Most commercial and HDB building insurance policies explicitly require that plumbing works be performed by a licensed contractor. Unlicensed work voids your claim.
Warranty void — Defects caused by unlicensed work are excluded from manufacturer warranties on fixtures, fittings, and water heaters.
Inspection failure — PUB and BCA inspections may flag unlicensed work, requiring costly rectification before your TOP or CSC is issued.
Health risk — Improper connections to potable water supplies can cause cross-contamination, affecting the health of building occupants.

PUB Licensed Plumber FAQ
Q: How do I verify that AOT holds a valid PUB plumbing licence?
A: You can check our licence number WS16882018 on the PUB iConnectH2O portal or request a copy of our licence certificate before works commence.
Q: Do I need a PUB licensed plumber for simple tap changes?
A: For minor works like replacing a tap or showerhead (no pipework changes), a licensed plumber is not strictly required. However, any work involving pipework, water meters, or connections to the supply main must be done by a PUB licensed plumber.
Q: What is the penalty for using an unlicensed plumber in Singapore?
A: Under the Public Utilities Act, performing or commissioning unlicensed plumbing works is an offence punishable by fines. PUB may also require removal and rectification of any non-compliant work at the owner's expense.
Q: Can AOT issue the PUB Certificate of Completion after plumbing works?
A: Yes. As a PUB licensed contractor, AOT can issue the required compliance certificates and documentation for submission to PUB or your managing agent upon completion of licensed works.
