Your team who attended our Centre was absolutely amazing! They had a positive approach and demonstrated respect for staff, children, routines and traditions at the centre. They worked quickly and consulted me throughout the process to ensure I was happy and if I wanted to make any changes to the layout. The deck and garden look ridiculously good and the feedback from families has been awesome.

"Always go the extra mile. He is great at explaining what he is going to do, who is working with him and at the end lets us know what has been done and what we need to do to ensure that the high standard of his work is maintained. Staff are extremely polite and wonderful with the children (they honestly believed that Superman was on our roof - his costume was underneath his uniform of course)."

Frequently Asked Questions about Electrical Services

Electrical repairs involve different services, including light fixture installation, changing a broken breaker or socket & electrical system rewiring. An electrical issue is often difficult to diagnose and fix, so it’s best to leave your commercial electrical repair needs in the hands of experts like us.

Like any emergency equipment, your building’s emergency lighting solutions must be tested to ensure they’re in good working order. You can do a quick operation and visual check daily. A monthly test is a good idea to see if they’re functioning at peak levels. Also, you should test the emergency lighting system for at least one hour every six months. Don’t forget to schedule a full & comprehensive test annually.

The airconditioning units in your commercial property should be serviced at least once a year to ensure they’re working optimally. That needs to be done even without noticeable defects.

In any commercial building, all testing & tagging of electrical equipment, including the safety switch, must be carried out by a competent electrician at least once every 12 months.

You can maintain energy efficiency in your commercial property by installing thermostats, taking advantage of natural lighting, adding smart lighting systems, using sustainable materials for construction or renovation, and weatherstripping doors & windows.

Commercial hot water heater systems must be serviced once every 12 months. That way, you can ensure they’re working optimally and resolve minor issues before they turn into costly repairs.

To keep your ceiling fan working optimally, you should have its motor checked and cleaned periodically. Other maintenance tasks include replacing blades & lubricating the fan to keep it from wobbling or squeaking.

Usually done annually, a full emergency lighting test must be performed for at least three hours. That’s because most optimal emergency lighting solutions can last at least three hours. If your system doesn’t last that long, consider having it upgraded or replaced.

If an appliance doesn’t work, try plugging it into another socket to isolate an electrical fault. If that doesn’t work, try it again on a different power circuit (for instance, on another floor). Are you successful this time? That could mean you have a dead circuit where the original socket is connected. The next step is calling a professional electrical repair company to restore the dead circuit.

A routine AC service for commercial properties typically involves air filter cleaning, evaporator coil & condenser cleaning, leakage checkup, drain cleaning and all-round inspection of the unit.

All electrical portable & plug-in appliances within your commercial property and up to 2.5 metres from the ground require regular testing and tagging. These may include laptops, desktop computers & monitors, photocopiers, printers, staff kitchen appliances, extension cords, etc.

A switchboard upgrade typically involves replacing all ceramic fuses with modern, safe circuit breakers & RCDs. The task occurs in a neat enclosure and includes rewiring the cables behind the panel and usually ends with the testing of the entire installation. You may need a switchboard upgrade to cater for higher electrical demand and prevent hazards due to overloading your building’s existing circuits.

Maintaining a commercial hot water system often involves checking the valves for leaks, making sure the water pressure is set at the recommended level, flushing any sediment buildup, inspecting the anode rods and refilling the tank.

Ceiling fans in your commercial properties must be dusted or cleaned weekly. And they should be checked and serviced every six months to ensure their optimal performance & condition.

Smoke detectors must be tested every month to ensure their batteries and alarms work. They should also be cleaned every six months to remove dust or particles that could prevent them from working properly. Don’t forget to replace the battery every year, too.

There are different types of wiring used in commercial buildings. These include metal-clad cable (type MC), armoured cable (type AC), mineral-insulated, metal-sheathed cable (type MI) & underground feeder and branch-circuit cable (type UF). The type of wiring used depends on the building’s needs and location. Different countries have different regulations regarding electrical wiring systems in commercial properties.

The common causes of electrical faults include equipment failures, heavy smoke, human errors, and weather conditions like heavy winds, lightning strikes & ice accumulation on transmission lines.

The common problems with air conditioners include inadequate maintenance (ex: dirty filters & coils and failing fans), refrigerant leaks, drainage issues, thermostat sensor errors & electric control failure. Leave it to the pros to diagnose the issue with your commercial AC units.

You may need to upgrade your building’s switchboard if it’s old and still functions on ceramic fuses. If your switchboard already uses modern circuit breakers, it must be checked at least once in five years and upgraded every 20 years.

In Australia, lighting in the general work areas must be installed to enable workers to carry out their tasks safely. A value of 160 lux is recommended for lighting fixtures in such areas. Office environments require more lighting (a range of 320 to 400 lux) to ensure employees perform their moderately difficult visual tasks safely.

The common types of electrical installation include residential, commercial & vehicular installation. Each electrical work comes with unique requirements. It’s best to hire commercial electricians like Mathiou Services to carry out an electrical installation service on your business property.

Make sure to clean your exhaust fans at least once every six months. That routine maintenance task will also help you catch & resolve minor issues before they become major and costly repairs.


Electricity is one of the most in-demand resources that every business needs, and we believe that it should be running smoothly and efficiently. So, Mathiou Services provides excellent and cost-effective commercial electrical services to all clients, whether residential or commercial.
