Rewiring and renovation electrical work covers the jobs that go beyond a quick socket repair: replacing old wiring in a pre-war or ageing terrace house, upgrading the consumer unit (fuse box) to modern breaker standards, adding circuits for a kitchen extension or extra bedroom, laying conduit and cabling before plastering during a full renovation, and rerouting power points to match a new floor plan. In Kuala Lumpur this work is common in older neighbourhoods like Bangsar, Petaling Jaya border areas, and pre-1990s condos where the original wiring was never sized for modern air-con, induction hobs, or multiple appliances running at once. We list 41 businesses in this category, ranging from small two- or three-man outfits to larger firms that handle whole-unit rewiring alongside general renovation contractors.
Before hiring, ask for a site visit and a written scope rather than a phone quote, since wiring runs, wall-breaking, and consumer unit upgrades vary a lot job to job. Check that the electrician is registered with the Energy Commission (Suruhanjaya Tenaga) and can produce a wiring certificate on completion, which you'll need for insurance and for any future TNB inspection. Ask how they handle plaster and paint patch-up after chasing walls for cables, since that's often left out of quotes and becomes a dispute later.
Our ranked guide to electricians in Kuala Lumpur scores businesses on factors like responsiveness, review consistency, and the type of work they're actually rated for, so you can shortlist firms with a track record in rewiring rather than just general callouts. Details on how we build that score are on our methodology page.
