Frequently asked questions
Electrical wiring services are relevant for new fit-outs, renovations, upgrades, project works and selected residential, office or retail environments.
Yes. Wiring work often supports broader project scopes where security systems, network infrastructure and electrical readiness must align.
Yes, for certain scope. New wiring installations, three-phase supply upgrades and distribution board replacements require submission to Suruhanjaya Tenaga (ST) through a registered contractor. NEXT IN™, as a TNB Approved contractor, manages the permit application and ST submission process as part of the project scope.
TNB (Tenaga Nasional Berhad) approval means NEXT IN™ is authorised to perform LV electrical works connected to the national grid. This is required for supply upgrades, new meter installations and DB works — and gives clients assurance that all wiring is carried out to the required standard by a licensed contractor.
A standard office rewiring for a 2,000–3,000 sq ft space typically takes 3–5 working days depending on the number of circuits, cable runs and whether the DB needs to be replaced. NEXT IN™ provides a scope and timeline estimate after a site survey.
