Electrical installation in Hong Kong

Updated 4 November 2026

In Hong Kong a new electrical point is quoted from about HK$800, a branched point with up to 10 ft of cable from about HK$250, and lighting, outlet and switch installation from HK$1,000 to HK$3,000. The quickest way to a price for your flat is a request on BlaBlaPrice, where sellers reply with their own offer.

Registration and rules

Electrical work in Hong Kong is subject to registration. An electrical worker needs registration with an application fee of HK$475, and processing takes about 13 working days. An electrical contractor needs registration too, with a fee of HK$855 for a new application or renewal. Ask whether the electrician or contractor is registered and request the registration number in writing. The government's General Specification for electrical works sets the requirements for materials, workmanship and testing, so ask that the quote follows it.

When the power has to be switched off

If the supply must be disconnected for the work, the power company's temporary disconnection costs HK$1,460 per visit. Include that in the budget when the job needs it, and ask the electrician who arranges the visit.

Season: summer loads and timing

Summer, from June to August, is when air conditioners add the most load, which is why many homes add points before it. Winter, from December to February, is the calmer period. November sits between the two, so a booking now can be done before the summer rush.

How it is bought and measured

Prices are per point, per circuit, per hour for repairs or per job. Local price lists give cable lengths in feet, so write lengths in feet and metres, and write floor areas in m². Installers serve Central, Kowloon, Sha Tin, Tsuen Wan and Tuen Mun, so name your district when you post the request.

What to write in your request

Describe the work: new points, a branched point, a replacement switch or a fault. Add the materials and who supplies them, the site and its building address, the experience you need, your deadline and your budget. A photo of the distribution board or of the wall where the point goes lets sellers quote without a visit.

On BlaBlaPrice you describe the job in your own words in a chat, and a photo can be added. The AI asks for missing details, looks through sellers' websites and price lists in Hong Kong, and shows the prices and businesses it found. Registered sellers receive the request and reply in the chat with their own price and terms. Your contacts stay hidden until you decide to exchange them.
