Commercial Electrical Maintenance
for Offices, Factories & Strata Buildings

This page is price-free: an electrical-only scope is quoted against the assets it names, not from a rate card. The per-visit and retainer bands we publish for a whole-building contract are in our building maintenance services guide. Ask for a proposal on WhatsApp.

What a commercial electrical maintenance contract actually covers

A good contract covers the installation, not just the faults. That means the fixed electrical infrastructure of the building and the condition it is in — not only the things that have already gone wrong.

In a typical Klang Valley office, factory unit, shoplot or strata block that means the main switchboard and its protective devices, sub-mains to floors and units, distribution boards, final circuits and their protection, earthing and bonding, the lighting installation including emergency lighting, socket and small-power circuits, and the electrical side of plant such as pumps, lifts, gates, ventilation and air-conditioning. It also covers the boring but decisive things: labelling, board schedules, spare-way records, and whether anybody can find the isolator in a hurry.

What it does not cover is fire protection. Installing and servicing fire alarm, sprinkler and extinguisher systems is Bomba-registered specialist work, which ClickBina coordinates rather than performs in-house. Lifts are their own regime as well — they are maintained by a registered lift contractor and carry a DOSH Certificate of Fitness, as our lift maintenance cost guide → explains. A good electrical contract acknowledges both boundaries in writing rather than blurring them.

Why this is not an electrician call-out

Most buildings start by calling someone when a breaker trips, and that is a perfectly good way to buy a repair. It is a poor way to run a building, because nobody is ever looking at the installation as a whole:

For a home or a single unit, the call-out model is right and our electrician services hub → is the page you want. For a building with tenants, staff or a committee answering for it, the contract earns its keep on the first avoided outage.

The assets your scope must name

The single biggest determinant of whether a contract works is whether it lists assets or uses adjectives. “General electrical maintenance” means nothing. Name them:

Two of these deserve a specific note. Emergency lighting function testing is worth naming explicitly, with the result recorded — it is the classic asset that everyone assumes somebody else checks. And the generator changeover is a life-safety interlock: it must make it impossible to be connected to the grid and the set at once, which is exactly why that tie-in is work for a competent electrician registered with Suruhanjaya Tenaga. Our generator installation guide → covers why.

Who may legally do the work

We will state only what is settled. In Malaysia, wiring and electrical installation work must be carried out by a wireman registered with Suruhanjaya Tenaga (the Energy Commission) under the Electricity Supply Act 1990, and larger or higher-capacity installations fall under the supervision of a registered chargeman. Where the work touches the supply — a capacity change, a new connection, a load assessment — that is a competent person registered with Suruhanjaya Tenaga, and only a registered contractor can issue the certification the utility needs. Our three-phase power upgrade guide → walks through what a proper load assessment involves.

Unregistered electrical work is illegal, and beyond the legal exposure it can void insurance if a fault causes a fire — which for a commercial building is a much larger number than the maintenance contract ever was.

What we deliberately do not publish here is which competency class or category your particular installation requires, or how often anything must be inspected. That depends on the installation, and printing a class or an interval that does not match yours would be actively harmful. Do this instead, at tender:

• Ask the contractor to name the registered person who will supervise your installation and to produce their current registration — not a company brochure.
• Ask them to state, in writing, which requirements they consider apply to your installation and what they are proposing to do about each.
• Confirm the position independently with Suruhanjaya Tenaga where anything is unclear, and keep that confirmation with the contract.
• Ask for current CIDB registration and grade for any construction or installation works element.

A contractor who cannot produce a named registered person on request has answered the most important question in the tender.

Scheduled, reactive, and what “response time” should mean

Every workable contract has two halves. Scheduled work is the agreed visits against the named asset list — the part that finds problems before they are outages. Reactive work is what happens when something fails anyway. Buy both from the same contractor and the reactive half is attended by someone who already knows your boards.

Response time is the number people negotiate hardest and define worst. Make it mean something:

• Define priority levels. A total loss of supply to a floor is not the same as a flickering corridor light. Two or three tiers is enough.
• Define the clock. Response means someone competent on site — not an acknowledgement email. Say when the clock starts and when it stops.
• Define hours. Office hours, extended hours or genuine twenty-four-hour cover are three different prices. Pick honestly.
• Define what happens on breach. A target with no consequence is an aspiration.

The scheduling logic is the same one our planned preventive maintenance guide → sets out for the whole building — this is that discipline applied to one trade in depth.

The records you should be handed

For a strata committee this paperwork is not administrative decoration. Under section 21(1) of the Strata Management Act 2013 the management body must keep the building and common property in a state of good and serviceable repair, and a defect register with dates is how a committee demonstrates at the AGM that it has been doing so.

How these contracts are priced

We publish no rate card for an electrical-only scope, because the price is a function of the asset list, and no two buildings have the same one. What we can tell you is the shape of the commercial arrangement, so you can compare bids that look different on the surface:

• Ad-hoc / per visit. No commitment either way. Right for a single small unit, wrong for a building, and the most expensive per attendance.
• Scheduled visits only. A fixed number of visits against the named asset list, with reactive work quoted separately as it arises. Predictable and easy to budget.
• Retainer with included reactive cover. Scheduled visits plus a defined amount of reactive attendance inside the fee. Check carefully what counts as included — that definition, not the headline fee, is the deal.
• Comprehensive (labour and parts). Materials inside the fee. Simple to budget, and the contractor prices the risk, so read the exclusions list closely.
• Per-door or per-unit for a portfolio of similar units.

Whichever shape you choose, the exclusions do the real work. Insist on a written list of what is not included — consumables, lamps, replacement protective devices, out-of-hours attendance, access equipment, and anything behind a locked tenant door. For the per-visit and monthly retainer bands we publish for a whole-building, all-trades contract, see building maintenance services →; an electrical-only scope sits inside that picture rather than beside it.

Writing the scope and tendering it

A tender is only useful if every bidder prices the same thing. Build the document in this order:

1. Asset register first. Walk the building and list what exists — boards, their locations, plant, lighting types, the generator if there is one. Bidders who have to guess will either pad the price or discover the work later as a variation.
2. State the demise boundaries. Which boards are the landlord’s, which are the tenant’s, and who pays for what behind a tenant door.
3. Set the scheduled scope per asset — what is done, and how often, for each line.
4. Define priority levels and response targets, with hours of cover.
5. List the records required after each visit, and the format.
6. Require named registered personnel and current CIDB registration and grade.
7. Ask for the exclusions list as part of the bid, not after award.
8. Set the term and the exit. Twelve months with a notice period beats a three-year lock-in with no performance test.
9. Invite at least three bidders, including the incumbent if there is one.
10. Evaluate on total cost of ownership — fee plus expected excluded items — not on the headline monthly figure.

Committees have an extra step: the appointment itself has to be done properly and minuted. Our guide to appointing contractors for strata → covers that process.

Offices, factories, shoplots and strata common areas

• Offices. Small power and lighting churn constantly as fit-outs change, so board schedules go stale fast and the emergency lighting is the asset most often forgotten. Pair this with office aircon maintenance → — the two contracts cover most of what actually stops an office working.
• Factories and warehouses. Heavier loads, motor starting, dust and vibration, plus process plant added over the years with nobody updating the records. Thermal inspection of boards earns its money here, and any new plant is a load question before it is an installation question.
• Shoplots and F&B units. Heavy kitchen loads on installations designed for something lighter, extraction and refrigeration running long hours, and a fit-out history nobody documented. See retail fit-out cost → and kitchen exhaust & ducting →.
• Strata common areas. Pumps, lifts, gates, car-park and landscape lighting, the guardhouse and common corridors — all under a committee that has to answer for spending at the AGM. Records matter more here than anywhere else; JMB responsibilities & duties → and the JMB/MC compliance checklist → set out the wider obligations this contract sits inside.

Where these contracts go wrong

• A scope written in adjectives. “General maintenance of the electrical system” is unenforceable. If the asset is not named, it is not covered, whatever anyone intended.
• Nobody checked the registration. The one document you will be asked for after an incident is the one nobody requested at tender. Get the named person and their current registration on file at the start.
• Response time with no definition. “Four-hour response” that means an email reply is not a response time.
• No records handed over. Without visit reports and test results there is no trend, no evidence, and nothing for a committee to show at the AGM.
• Board schedules never updated. Every fit-out changes the boards. A schedule that no longer matches reality is worse than none, because someone will trust it in an emergency.
• Exclusions discovered after award. Ask for the exclusions list as part of the bid.
• Assuming fire systems are included. They are not — alarms, sprinklers and extinguishers are Bomba-registered specialist work, coordinated separately. Say so in the contract so nobody assumes otherwise.
• A long lock-in with no performance test. Start with a shorter term and a notice period, then renew on evidence.
