Hiring an electrician in Malaysia: finding one, checking them, paying fairly and judging the work

Most of the friction between Malaysian homeowners and electricians isn’t about the wiring. It’s about money nobody mentioned up front: a RM50 transport charge for a ten-minute job, a “free” site visit followed by silence, a RM2,000 house job that turns into a RM4,000 bill, or the last 10% that never gets paid. The fixes are boring and they work: agree the visit charge before anyone drives over, get a written quote that names the parts, price every addition before it’s done, and pay in stages that match finished work.

This guide pulls together what electricians and homeowners argue about in Malaysian wiring groups, checked against the Electricity Regulations and Suruhanjaya Tenaga’s (ST, the Energy Commission) wiring guideline. The rules and register below are Peninsular Malaysia’s and Labuan’s: Sabah now has its own energy regulator, and Sarawak licenses wiremen under its own grades (G1 and G2), though the advice on fees, quotes and payment applies anywhere. Our Johor Bahru electricians guide lists actual businesses and advertisers in JB.

Where people actually find an electrician

Most electricians who take house jobs don’t have a website. They work from a WhatsApp number and find work in Facebook groups, in residents’ groups and through word of mouth. A Google Maps listing with reviews helps for the businesses that have one, but many small operators aren’t on Maps at all.

A request post gets replies fast. In the national Malay-language wiremen’s group, Pendawai Elektrik, a Cheras homeowner’s request for a registered contractor to fix tripping, change a DB and add aircond and water-heater points drew more than 50 replies with phone numbers or WhatsApp links. A Gombak request for someone to inspect a contractor’s work got 32 out of 42. Almost all of those replies are people advertising themselves. Independent recommendations from past customers are rare, and in the Johor groups we studied, some of the most “recommended” numbers turned out to be the same wording posted by several accounts.

So treat a request post as a way to collect candidates, not as a vetting step. It works better when you give people enough to price from:

  • your area (taman and town), and whether it’s a house, condo or shop;
  • the job in plain terms: “tukar DB single phase”, “tambah 3 point plug”, “RCCB selalu trip bila hujan”, “wiring rumah baru dua tingkat”;
  • a photo of your DB or the problem, and for new wiring, a floor plan or a list of points;
  • whether you’re buying the materials yourself (labour only, “upah sahaja”) or want a supply-and-install price.

For small jobs, your own residents’ group or a local electrical group usually beats a national one: a nearby wireman doesn’t need to charge you for an hour on the road. A Kuala Lumpur post that listed every point for a job in Kuchai (11 light, 4 fan, 3 aircond, 3 socket points and so on) got directly comparable quotes within the thread, which is much easier to judge than “berapa harga wiring rumah?”.

Who is allowed to do the work

The rule is stricter than most people assume. Under regulation 75 of the Electricity Regulations 1994, no one may carry out “electrical work” without being registered with ST as an electrical contractor, and the regulations define electrical work to include repairing, altering, adding to and “the replacing of any of its parts”. On paper, that covers swapping an MCB.

For wiring itself, regulations 12 and 13 set out who supervises and who tests:

  • Single-phase wiring (almost every house) must be done under the immediate supervision of a wireman with a single-phase or three-phase certificate, employed full-time by a registered electrical contractor. When it’s finished, that wireman signs the Supervision and Completion Certificate, Form G.
  • The finished work must be tested by a wireman whose certificate is endorsed for testing, who signs the Test Certificate, Form H. ST’s domestic wiring guideline lists the tests behind it: continuity, insulation resistance, polarity, earth electrode resistance, RCD (RCCB) test and earth loop impedance.
  • The owner submits Forms G and H to TNB, and TNB won’t connect a new installation without them.

Two more details matter to homeowners. ST’s guideline says Forms G and H stay valid only while the wiring is unchanged: once additional wiring is done, they’re void, and new forms must be issued by an electrical contractor and a competent person. And under regulation 11, adding points to a house usually doesn’t need TNB’s approval first, as long as the extra load stays within the maximum demand in your supply contract.

What the grades mean when you hire:

GradeWhat it coversWhat it means for you
PW1Single-phase wiringCan wire under a contractor, but can’t test and sign Form H
PW2Single-phase wiring plus the testing endorsementThe usual grade for house wiring, DB changes and extra points
PW3Three-phase wiringThree-phase work, without testing
PW4Three-phase wiring plus testing, and single-phase tooQualified for your house job; many PW4 holders work mostly on commercial and industrial jobs
Chargeman (A0, A1, A4…)Operating and looking after installationsA separate certificate, not a wiring grade
Electrical contractor, class A–DThe registered companyClass D: single-phase installations only, jobs up to RM100,000. Class C up to RM500,000, B up to RM1 million, A above that

Every class of registered contractor has to employ at least one wireman authorised to test (single-phase for class D, three-phase for the others). In ST’s register in October 2026 there were about 15,000 PW4 registrations against 5,300 PW2, and about 7,800 registered electrical contractors, most of them class C.

What does this mean in practice? Electricians in the groups are frank that the rule isn’t how much of the market works. In a thread about checking competency, one commenter said he works without any certificate and “rents” a licence when an owner insists on paperwork, adding the cost to the price. Another said many certificate holders no longer wire at all and only oversee the people who do. For a socket or a light fitting, that may not worry you. For new wiring, rewiring, a DB change or anything that needs TNB’s connection, ask up front who will test the job and sign Forms G and H, and which contractor they’re signing for. TNB needs those forms for any new supply or upgrade, and an extension voids the old ones, so a wireman who can’t produce them can’t finish that kind of job properly.

DIY happens, and step-by-step instructions for swapping a breaker get posted freely in the repair groups. The law doesn’t carve out an exception for homeowners, though, and anything at TNB’s side of the meter is TNB’s equipment.

Checking someone on ST’s register

ST publishes its list of registered competent persons (wiremen, chargemen and others) and its list of registered electrical contractors. Choose the ST area office (Pejabat Kawasan) for your state, search (Cari), and look for the name, certificate number or phone number. A person’s entry shows the name, certificate number, grade, area office, phone, the employer’s company registration number (ROC), state and expiry date. A contractor’s entry shows the class, company name, ROC, phone, email, validity dates, town and the nominated competent persons. TNB also has a contractor search by name, ROC, state and city, using ST’s data. Only currently valid registrations are listed.

The easiest way to check is to ask for the certificate number and the contractor’s name, then find both. Don’t rely on the phone number. Of 389 numbers that electricians advertised in Johor Facebook groups, only 4 matched any register entry: registered people often advertise under another number, and some advertisers aren’t registered at all. A match is a useful signal; no match proves nothing until you’ve asked.

The register also can’t tell you who wants your job. A shortlist of PW2 wiremen near a Skudai house, drawn from the register alone for a DB change, mostly didn’t reply; many were salaried staff of specialist firms, and the one business that answered quoted RM3,700, where a small single-phase DB replacement usually costs RM350–600. Find people where they advertise for work, then check the ones you’re considering.

Call-out, transport and site-visit fees

This is the most argued-about topic in the groups. A Pendawai Elektrik post asking why so many owners resent a transport charge drew over 100 comments, and the electricians’ answers explain a lot.

Their side: the drive costs fuel, tolls and an hour or two, and a free visit often ends with nothing. One wireman described three site visits in a day, in Bangi, PJ and Shah Alam, and all three customers went quiet after the quotation. Another drove 10 km on the eve of Hari Raya to replace an RCCB, and the owner balked at the agreed transport charge because the job only took a short while.

Their most-liked advice to each other is telling: don’t write “duit minyak” (fuel money) on the bill, because customers hate it. Call it a diagnostic or service charge, or fold it into the labour, and say it before you come. So when a quote has no transport line, you’re still paying for the trip.

What individual electricians said they charge, from 2026 threads (each row is a spread of answers, not a survey):

ChargeReported figures
Transport for a small jobOne: RM50 for 0–20 km. Others: RM30 beyond 2 km, RM1 per km return, nothing under 5 km
Site visit to quoteOne reply: at least RM50 or RM100. One wireman’s RM100 is deducted from the bill if you go ahead, otherwise it covers his transport
Troubleshooting a tripping houseAnswers ranged from RM50–90 (Shah Alam/Klang) through RM150–250 single-phase and RM250–450 three-phase, to RM300–800 single-phase and RM400–1,500 three-phase; parts extra
After hoursOne tariff adds RM100–200 after 7 pm or on public holidays
Inspecting another contractor’s workReplies to a Gombak request ranged from RM150 for a site visit and inspection to RM700 from a competent person with clerk-of-works experience

When a homeowner asked whether “transport RM50 plus troubleshooting RM150” was expensive, most of the replies said it was cheap; the figures they gave for their own visits were mostly RM180–400, two said they charge RM150 an hour, and a couple put a normal job at RM600–1,500 or more depending on scope. A minority do check for free and only charge for the repair. Ads in the groups advertise “troubleshooting from RM80” or a free site visit, which usually means the cost is in the job price.

The practical move for you: ask what the visit costs before anyone comes, whether it’s deducted if you go ahead, and what happens if they find the fault but you’d rather buy the part yourself. For tripping, describe the symptom first (which breaker trips, when, whether it happens in rain). Our RCCB tripping guide helps you tell a fault-finding visit from an unnecessary rewire.

The other side of the coin is real too. A JB homeowner’s warning post describes a “24-hour” electrician found on Facebook who charged RM100 just to come, dismantled the light switches and then all the wiring in the DB, declared that everything had to be replaced for RM1,600 plus RM100, and walked off leaving the DB disconnected when the owner asked whether only the two faulty parts could be changed, still demanding the RM100. A second electrician found none of the DB wiring properly connected. A visit fee is fair; an open-ended teardown followed by a take-it-or-leave-it rewire is a warning sign.

What small jobs cost

Small jobs are where expectations drift furthest from what electricians will accept, because the trip costs the same whether the job is one light or ten.

  • One light fitting, a long drive away: a wireman’s RM50–80 was called expensive by an owner who thought RM10–20 was the going rate. Replies put the fitting labour at RM20–35 and the trip at RM50; most said to quote it all-in before going, pass it to someone nearer, or decline.
  • One fan regulator and one light, labour only, 10 km away: replies ranged from RM35 to RM350, clustering at RM80–130. One itemised it as fan RM70, light RM25, transport RM20–35.
  • An MCB changed by a condo’s management handyman who didn’t name a price: the breaker itself costs RM5–10. Answers in over 100 replies ran from RM15 to RM150, with RM30–50 the most common for a handyman already on site; an outside electrician would charge at least RM50, and RM100–150 with transport. The photo showed a burnt C20 MCB, and the useful replies said to find out why it burnt: a loose terminal, an overloaded circuit or an undersized cable. One reply suggested fitting a bigger 32A breaker and was corrected: on 2.5mm² cable, a bigger breaker just removes the protection. The cable size sets the breaker, not the other way round.

Per-point prices for new wiring, DB changes, aircond and water-heater points are in our house wiring prices guide.

Labour-only jobs and day rates

Buying the materials yourself and paying only for labour (“upah sahaja”) can save money, but electricians set conditions. Many will take a day rate of RM250 or more if the owner supplies everything, down to the tools; one listed RM250 wages, RM20 meals, RM20 fuel and RM100 tool rental. Their most common complaint is an owner who buys the materials but asks the wireman what to buy, then haggles the labour. Get the material list from them in writing if you go this way.

For a sense of labour costs behind a quote, the helper rates electricians pay are a useful benchmark. In a 2026 thread, RM70 a day plus lunch was the commonly accepted figure, RM50–60 in Sarawak, RM80–85 in Kuantan and Kelantan, RM100–110 for a semi-skilled helper and RM130 or more for a skilled one. Wiremen’s job ads in KL and Selangor offered RM120–150 a day. One reply to the Kuchai job estimated a week’s work for a wireman at RM200 a day and a helper at RM150. Labour-only quotes for that job (57 items across 9 types) mostly ran RM2,500–3,800; one quote including surface wiring materials, but not the fittings, was RM4,400, and one outlier was RM8,500.

Quotes, extra work and payment stages

Almost every dispute in the groups goes back to a vague quote. Ask for one that lists:

  • every point by type and number, and whether wiring is surface (casing) or concealed (piped in the wall);
  • the brands and models of switches, sockets, breakers and the DB, ideally with a photo or model number;
  • cable sizes for aircond and water-heater circuits;
  • whether testing, Forms G and H, and a TNB application are included;
  • what counts as extra, and how it will be priced.

The switch-design argument shows why. An owner asked for extra switches and sockets without saying which kind, then disliked the standard white ones after installation. Electricians agreed the owner should pay for new ones plus labour, and that the wireman should have named the brand or shown a sample first.

When you add or change work mid-job, electricians call it a variation order: price it, agree it, then do it. Their own advice to each other is to write “any additional work will be quoted separately” into the quotation. One wireman described wiring a house from bare walls on an agreement of a little over RM2,000. The owner kept adding things, the final bill was RM4,000, and the payment was only settled with the police involved. The practical replies agreed: put each addition in writing with its price.

Payment stages that electricians described for house wiring:

StagesWho described it
50% before starting, 40% after installation, 10% after the owner checksSeveral wiremen
50% / 30% / 20%One wireman
40% deposit, 20% after piping, 20% after wiring, 15% after fittings and DB, 5% on satisfactionOne wireman
50% / 20% / 20% / 5% / last 5% one month after handoverOne wireman who says he’s never been left unpaid
60–70% up front with a written agreementCompanies
Hold 10% for six months against defectsOne reply

A deposit of 30–70% is normal because the electrician buys the materials. What protects you is tying later payments to visible milestones and keeping a final 5–10% until the circuits have been tested and work. One homeowner asked whether to pay a 40% second instalment when the wiring was finished but the downlights, fans and loop testing were waiting for the painter. The one reply that addressed it directly: follow the terms you agreed, and agree them before work starts, not halfway.

Electricians have their own horror stories: months of chasing a balance, owners paying RM500 a month on a RM10,000 job, a two-storey house where the wireman only got paid after he started removing the wiring. Understanding that is why many now insist on a deposit and progress payments.

What bad work looks like

You don’t need to be an electrician to spot some warning signs, and the groups are good at reviewing photos. When a homeowner posted a photo of their three-phase DB and asked whether it was fine, electricians pointed to:

  • Cable colours not matching the phase from breaker to load, which makes later fault-finding slow. (The phase colours are changing: ST now allows brown, black and grey instead of red, yellow and blue, mandatory from 2029, so what matters is consistency, and labels where old and new meet);
  • an unbalanced load, with the yellow phase carrying roughly twice as many circuits as the other two;
  • 32A breakers on cables that looked too thin for 32A;
  • one RCCB short: one reply said lighting, aircond and water-heater circuits should sit on one RCCB and power circuits on another.

Other things electricians flag in photos and job reports:

  • breakers or cables that are browned or melted around a terminal (see why DB boxes catch fire);
  • an aircond or water-heater point run in 2.5mm² cable when you paid for 4mm²;
  • cables buried in walls without conduit. This one is disputed: some say double-insulated cable buried directly was normal practice in houses built before about 2007, while others insist on piping. ST’s current guideline (clause 8.6(b)) requires conduit or trunking for all home wiring, so new work should be piped. Either way, ask for a drawing of where concealed cables run, so nobody drills into one later;
  • a “DB change” that’s really a new cover over the old breakers. Our DB upgrade guide explains what a proper replacement includes.

If you’re unsure about finished work, a second electrician’s inspection costs roughly RM150–350 going by the replies above (one competent person asked RM700), and it’s worth asking them to test rather than just look. A wireman’s story in Pendawai Elektrik shows why: at a hotel, a “wireman” called in after a plumber drilled through a cable claimed the aircond and water-heater boards were damaged and the whole room needed rewiring. A second wireman opened the patched wall and found the cables cut instead of joined, rejoined them, tested and filmed the result.

Warranty and when it goes wrong

Electricians’ ads in the groups offer wiring warranties from three months to as much as five years, most often three months, one year or two years. Get the period in writing on the quote or invoice, and keep the electrician’s name, number and the contractor’s registration. If your house is new, the developer’s defect liability period is 24 months from vacant possession under the standard sale agreements (EdgeProp’s explainer), so report wiring defects to the developer first, and ask before having anyone alter the original wiring.

When a job goes badly:

  • Write it down. Photos of the work, the quote, payment receipts and the WhatsApp chat are what every dispute in the groups came down to.
  • Get a second opinion with tests, not just a look.
  • For money claims, the Consumer Claims Tribunal (Tribunal Tuntutan Pengguna) hears consumer claims up to RM50,000.
  • For safety and competency issues, contact your ST area office, which registers the contractors and competent persons in its state.

Before you agree to the job

  • Ask the visit or troubleshooting charge before anyone comes, and whether it’s deducted.
  • For anything beyond a fitting swap, ask who will test it and sign Forms G and H, and check that person and their contractor on ST’s register.
  • Get an itemised quote with brands, cable sizes and what counts as extra.
  • Price every addition before it’s done.
  • Pay in stages tied to finished work, and keep the last 5–10% until it’s tested.
  • Keep photos, receipts and chats.

If you’re in Johor Bahru, our JB electricians guide has local businesses and advertisers to start with. Before a DB job, the DB upgrade guide tells you what to ask for. If the job involves an EV charger or a bigger supply, read single- vs three-phase first, because a three-phase application has to go through a registered contractor.
