Gas boiler & water heater repair

Gas boiler and water heater repair

Updated 4 November 2026

No single repair price for a gas water heater or boiler appears in the local results, so the nearest published figures are for installation work. Removing an old water heater costs about HK$150, an instant-type unit is installed for HK$500, and a new gas water heater model starts from about HK$7,665. For a repair price on your fault, send a request on BlaBlaPrice.

Local rules and what to check

Gas appliance work in Hong Kong must follow the Gas Safety Ordinance (Cap. 51), and the official installation guidance is written for registered gas contractors, so ask your technician for proof of registration. Boilers and pressure vessels also have a government code of practice for owners, and an appointed examiner can inspect them. Unvented electric storage water heaters need permission from the Water Authority before installation, so check that first if your unit is electric.

Why winter is the busy time

Winter, from December to February, is when people rely most on hot water and heating, so a faulty boiler is most urgent then. Book a check before December, so a fault does not leave the home without hot water in the cold months. A fault in summer, June to August, still needs the same repair, so do not wait for cold weather to act.

How it is bought here

Standard installation fees apply to Hong Kong, Kowloon and the New Territories, and a surcharge applies to special areas, so name your district when you ask, whether it is Central, Sha Tin, Tsuen Wan or Tuen Mun. Removing the old unit is often a separate line on the price list, so ask whether it is included. Some providers book gas appliance maintenance by appointment, seven days a week, and some gas suppliers sell monthly maintenance plans that include labour and regular safety inspections.

What to write in your request

Name the device, its make and model, and whether it is an instant or storage water heater or a boiler. Describe the fault or the service you need, the unit's age, the address or area, the day you want the visit, and whether you need a repair warranty. Add your budget. A seller who knows these facts can give you a firm price.

Free for buyers. Describe the fault in your own words in the chat and add a photo of the unit if you like. The AI asks for anything missing, looks through sellers' websites and price lists in Hong Kong, and shows the prices it found. Registered sellers receive your request and reply in the chat with their own price, terms and warranty, while your contact details stay hidden until you decide whom to share them with.
