Electrical work covers sockets, lighting, power trips and rewiring. In Hong Kong the important question is not just whether it works, but whether the contractor is registered — so ask for the registration number and check it yourself on the EMSD public register before you commit.
Full price list
All reference prices are in Hong Kong dollars (HKD).
Every price here is the published starting rate for the work shown, not a quotation. The tradesman prices the job after seeing the site, so parts, transport and access to old buildings can move the final figure.
- Light switch / socket replacement per visit
- Ceiling light fitting per fitting
- Power trip troubleshooting per visit
- Full wiring inspection per unit
- Exhaust fan installation per unit
- Certificate of inspection (WR1) per certificate

Common questions
Why can two electricians quote very different prices for the same job?
The work looks identical from outside, but what decides the price is what is behind the wall. Old rubber-insulated wiring, chasing a channel into a concrete wall and finding the existing cable run all add time, while a straight swap of a socket on an accessible wall does not. Ask each quote to list the labour, the materials and the number of hours expected, then compare them line by line.
Does the quote include the call-out fee, the parts and the removal of the old fittings?
It depends on how the quote was written, so read it before you agree. Some charges a separate inspection fee that is deducted from the price if you go ahead with the work, others fold the call-out into the labour. Parts should be listed by item and size, and removing the old socket or lamp should be stated rather than assumed.
Why does replacing one switch sometimes turn into a wall-cutting job?
The switch face is the cheap part; the cable behind it decides the cost. If the wiring runs inside an unknown plaster or concrete wall, the electrician has to cut a channel, find the route and make the wall good again afterwards. A surface-mounted box or a fitting on an accessible wall keeps the job small, so tell the contractor where the switch sits and whether you are willing to open the wall.
What is covered by the warranty, and who is responsible for a fault afterwards?
Most contractors give a written period on the labour they did, while the parts carry the terms of the manufacturer or the supplier. Ask for that period in writing together with what happens if the same point fails again: normally the contractor returns and re-checks the same fault at no charge. If you rent, the wiring and fixed fittings belong to the landlord, so a fault in them is a landlord matter rather than yours.
How do I check the work before the electrician leaves?
Test it in front of the electrician rather than after they have gone. Switch on every fitting that was touched, check the light and the socket at the points that were replaced, and ask which circuit each one now belongs to. Look at the paint or plaster around the new boxes so any cracks show up while the job is still on the invoice.
Do I need permission from the building or the landlord before the work starts?
If the work involves drilling, chasing a channel or changing the distribution board, most management offices want the contractor details and the working times submitted in advance, and some set permitted hours for noisy work. As a tenant, any change to the fixed wiring should be confirmed with the landlord in writing, because the wiring belongs to the owner and you may be asked to restore it when you move out.
Before you book
Before you book, get the scope and the unit prices in writing, and check whether the quote includes the call-out inspection fee, the parts and the removal of the old fittings. Agree how the money is split, such as a deposit and the balance on the day, and pay the balance only after the fittings have been tested in front of you. Keep the job report and the payment record, and confirm with the management office or the landlord before anything is drilled or rewired.
How the prices work
The reference figures cover the common household steps, such as a switch or socket replacement and a ceiling light, and they are a starting level rather than the bill you will be charged. What moves a real quote is the condition of the wiring, whether a channel has to be chased and a cable route found, the wall material, the part specification and whether the work happens outside normal hours. A fitting change on an accessible wall normally sits close to the reference figure.
