Gas boiler & water heater repair

Gas boiler and water heater repair in Singapore: costs and licences

Updated 4 November 2026

In Singapore, replacing an instant water heater starts from about S$120, and installing a storage unit without the heater costs about S$200 to S$450. Repair firms usually quote after an inspection, so the price of a fault is not published in advance. To get current offers, describe the heater and the fault in one request on BlaBlaPrice.

Licences for gas and water work

Regulated water and sanitary plumbing works in Singapore must be done by a PUB Licensed Plumber, apart from simple plumbing works, so ask the repairer for the licence before work starts. Gas work needs a gas service worker licence: the application fee is S$50 and non-refundable, and the licence fee of S$30 is payable on approval. Ask whether the quote is for a licensed or unlicensed replacement, because the two are treated differently under PUB rules.

Faults that bring people in

Because Singapore is hot all year, a water heater is used every month, so a fault is not seasonal and demand has no winter peak. The repair listings point to the common faults: no hot water, leaks and a heater that trips the power supply. Some firms offer 24/7 emergency callouts and free inspection, which is worth asking for when the heater fails at night.

What to write in the request

Name the device, the make and model if you know them, the fault, and whether the heater is instant or storage. Give the heater's age, the address or area (Singapore, Tampines, Jurong West, Woodlands or Ang Mo Kio), and when you need the work. Ask whether the repair carries a warranty and whether the quote includes removal of the old unit. Gas piping, from about S$100, and waterproofing, from about S$20, are often priced as separate add-ons.

BlaBlaPrice's AI reads your request, asks for missing details such as the make and the area, and looks through sellers' websites and price lists in Singapore before it shows the prices and businesses it found. Sellers registered on BlaBlaPrice receive the request and reply in the chat with their own price and terms. Your contacts stay hidden until you choose whom to contact.
