Cost Guide for Electrical Rewiring in Singapore

Electric wiring and rewiring are two of the most challenging tasks when you’re renovating or putting up a new home in Singapore. It’s particularly evident for HDB flats where old lines can turn into safety headaches due to the high humidity. Typically, rewiring services require time and skill, so you must rely on EMA-licensed professionals who understand the rules and how to avoid potential dangers. Whether home or office, you need to consider aspects like picking the right materials (say, NM cables for dry spots) and setup styles (like hidden conduits for that neat look). 

For 2025 costs, it depends on your property’s size and what needs doing, but for HDB flats, you’re looking at roughly $2,000 to $3,500 for a 3-room setup, $2,500 to $4,500 for 4-room, and $3,000 to $5,500 for 5-room jobs, covering work, stuff like copper wires, and any permits. Things like throwing in mandatory RCCBs or fancy smart add-ons can push the bill higher, so shop around with a few licensed quotes.

Types of Electrical Wiring and Rewiring Services in Singapore

For electrical wiring and rewiring services in Singapore, the priority revolves around safety, conformity to EMA regulations, and meeting contemporary demands for power. As the 2025 revisions highlight increased electrical loads and essential protection features such as RCCBs to every household, licensed electricians provide various services to upgrade aged infrastructure, avert dangers such as fire or trips, and integrate smart technology. These services involve full or partial rewiring, special-point installations (such as aircon or water heater installations), and emergency repairs.

Common Electrical Rewiring Services Offered

Singapore’s electricians provide tailored packages, often bundled for renovations or resale units over 20 years old. Here’s what you can expect from top providers:

• Full House Rewiring: This comprehensive service replaces all old wiring to meet current codes, ideal for older HDBs with degraded PVC cables (lifespan around 25 years). It includes upgrading the DB box, adding circuits for increased loads, and installing surge protection. Many electrical companies handle this for residential and commercial spaces, ensuring minimal disruption, usually 3–7 days for a 4-room flat.
• Partial Rewiring and Extensions: Suitable for targeted updates focused on damp-area wiring, usually in kitchens or bathrooms. This might involve adding power points, sockets, or extending lines for new appliances without a complete overhaul. 
• HDB-Specific Packages: Many electricians offer standard setups for public housing. The offers often include 8–15 light points, 9–15 power sockets, and dedicated lines for aircon (15A), water heaters (20A), and hoods. Most wiring companies quote based on flat size and comply with HDB guidelines, like no embedding in RC slabs and using concealed conduits where possible.
• Emergency and Repair Services: Quick fixes for issues like power failures, tripping breakers, or frayed wires. Some electricians offer 24/7 options, which include troubleshooting, replacements, and testing, often with transparent pricing to avoid overloads in humid conditions.
• Specialised Electrical Rewiring: Beyond basics, services cover smart home wiring (low-voltage for automation), data/comms lines, or energy-efficient LED setups. For commercial needs, expect power distribution, switchboards, and tagging.

These services prioritise copper-based electrical wiring for durability, banning aluminium in homes per EMA rules, and incorporate fire-resistant materials to handle Singapore’s tropical climate.

Wiring Types Used in Singapore Electrical Wiring Services

Professionals select from compliant options based on your needs, blending safety with functionality:

• Non-Metallic (NM) Cables: Standard for dry indoor rewiring in bedrooms or offices, with colour-coded wires (brown/red live, blue/black neutral, green-yellow earth) in a flexible sheath. Affordable and common in HDB packages.
• Underground Feeder (UF) Cables: Enhanced for wet areas like bathrooms or kitchens, with individual plastic sheathing per wire to resist corrosion, key in humid Singapore.
• Conduit Wiring: Protective tubes (plastic or metal) for visible or concealed runs, insulated with nylon for heat resistance. Versatile for both residential extensions and commercial rewires.
• Armoured or Twin-and-Earth Cables: Tougher for high-traffic spots, with metal sheathing or bare earth wire, used in upgrades for heavy loads like appliances.
• Low-Voltage Wires: For lighter circuits in smart integrations, like doorbells or IoT devices, enclosed in plastic for safe, low-power handling.

Avoid outdated types like aluminium-coated leads, as they’re prohibited for domestic use to minimise risks.

If you’re spotting signs like warm sockets or flickering lights, it’s time to act. Rewiring isn’t DIY-friendly—reach out to reliable electrical companies for quotes. For trusted options, consider the best electricians in Singapore who specialise in these services for seamless, compliant results.

How to Pick a Good Electrical Rewiring Contractor in Singapore

Hiring an electrician in Singapore isn’t as tricky as it sounds, but knowing the ins and outs will help you avoid tripped breakers or even small fires from old setups. If you’re sprucing up an HDB or giving your condo a revamp, make sure you know EMA rules inside out. Starting July 1, 2025, RCCB breakers are now a must-have in every home – skip it, and you could face a $5,000 fine. Additionally, you should become acquainted with the HDB Installation Assistance Programme page for more clarity, especially if you’re going for solid rewiring chops.

Make Sure They’re Licensed and Certified

First off, double-check if they’re an EMA-approved Licensed Electrical Worker (LEW). No license? No deal – they’re the only ones allowed to do electrical rewiring legally in Singapore. You can look them up quickly on the ELISE public search portal or read the EMA guide on engaging licensed workers. Typically, reputable electricians will show certs from groups like the Institution of Engineers Singapore (IES) to show they’re legit.

Look at Their Track Record and Past Work

Although it’s not a critical factor, you should aim for contractors with 5 to 10 years of experience, especially those who have handled Singapore’s humidity successfully. Ask for samples of work they’ve done – maybe an HDB redo or a condo upgrade with hidden conduits and fresh DB boxes. If they specialise in HDB wiring for 3- to 5-room flats, they’ll probably wrap it up in 3 to 7 days without turning your home into a mess.

Dig into Reviews and Ask for Refs

Browse Google or local forums to see what people are saying – check for comments about whether they show up on time, tidy up, or fix stuff after. Avoid the wiring contractors with red flags in the comments. In some cases, you might want to ask the electrical company to give you 2 or 3 recent client contacts so you can chat about how they handled surprises during the job. Anything over 4.5 stars from a bunch of reviews (say 20+) usually means they’re solid.

Get the Scoop on Condo and HDB Rules

Rules aren’t the same for HDBs and condos, so your contractor needs to know the drill to get permits. In HDBs, an EMA-licensed professional must do everything, and you’ll need clearance for additional services like extra circuits or anything over 15 amps – no heavy appliances without it, and air-cons need their 20-amp switches. Wires must be installed in rigid PVC or metal pipes for protection. Additionally, if drilling into concrete, you need an HDB approval to ensure the building’s structural integrity. Check out the HDB guidelines on electrical works for the complete list of details. For condos, it’s all about hiding the wires neatly, usually post-wall-breaking but pre-tiling, particularly in bathrooms or kitchens. The MCST often wants a say in big projects, so the contractor should sort that out. Either way, that new RCCB rule hits both – make sure they test and certify it.

Shop Quotes and Check Warranties

Round up quotes from a handful, like 3 to 5, and get the nitty-gritty: how many points, what wires (copper’s king), when they’ll finish, and the price including permits or cleanup. Super cheap? Probably cutting corners. Stick with ones that back their work with a 1- to 5-year warranty and use decent, SS-approved brands.

Questions to Ask a Prospective Electrician

Before you shake on it, hit them with these to see if they measure up:

• How big is your team? (total staff strength)?
• What kinds of training and courses have your electricians been through?
• Can you provide a free written estimate outlining all the terms and conditions of the electrical works we discussed?
• What are the payment terms?
• Do you provide a warranty for your rewiring services or products?
• What brands do you carry or service?
• How long will the rewiring take? Will you clean up after the job is completed?
