Office Electrical Installation Services

Offices are full of electrical appliances, equipment, power cords, lighting, and the works. A quick glance around your office will have you realise how dependent we are on electricity and how serious the consequences of faulty electrics can be.

These day-to-day items in the workplace have become such an integral part of our work that we sometimes completely overlook the safety hazards they bring with them, especially if improperly installed or used incorrectly.

Compared to other workplaces, offices are fairly safe but that doesn’t mean there are no risks. There is no place out there that isn’t safe from the risk of electrical hazards, not even your home.

Electrical hazards in the office give way to electrical accidents and injuries that are the result of unsafe installations and work practices.

Read on to find out the services included in office electrical installation, how much they cost, and why they are so important:


Before we discuss more on the installation services, let’s talk about the most common electrical hazards in an office. They include, but are not limited to:

Overheated electrical equipment

Electricity generates heat which is why it is necessary to have proper ventilation to let it escape from the area. Improper installations with inadequate ventilation can be quite dangerous and may start electrical fires.

In addition to electrical fires, overheating may cause the electrical systems and equipment to get damaged and increase the risk of sparks, shocks, and burns.

Some common office equipment that tends to overheat include computers, printers, and photocopiers.

Overloaded outlets

It is not uncommon to see several electrical equipment such as computers, phone chargers, lamps, and several others, connected to a single outlet, especially if multiple desks share a power strip.

This results in the outlet drawing much more current than it can safely handle, and while most of the time it will cause the circuit breaker to trip, it may also increase the risk of shocks and fires.

Extension cords

Extension cords are another very common sight in offices used to connect appliances to a power source if there isn’t an existing socket nearby.

Albeit convenient, they pose a serious electrical and safety hazard and must only be used for limited amounts of time and that too very carefully.

Plugging too many appliances into one extension cord can increase the risk of overheating and should be avoided at all costs. In addition to that, the long wires may cause tripping and the cord unsafely being ripped out of the socket leading to sparks and fires.


An electrical installation includes all the fixed electrical equipment on a property such as the wiring, cables, accessories (sockets, switches, and light fixtures), and the consumer unit.

To ensure a good electrical installation, you need to hire an NICEIC certified electrician who has adequate knowledge of the correct procedures and the current wiring rules and regulations.

Some important considerations include:

  • Ensuring adequate sockets for all the electrical appliances in the office to minimise the use of multiway sockets and extension cords that lead to overheating.
  • Guarding live parts of electrical equipment against accidental contact,
  • Installing a Residual Current Device (RCD) protection to provide additional protection against electric shocks.
  • Proper grounding and earthing arrangements to ensure that the circuit breaker can eliminate an electrical fault before it turns into a hazard.
  • Installing enough circuits to avoid danger and to minimise issues in the event of a fault.


Electrical installation is technical work and must only be done by a qualified electrician. It can be extremely dangerous for an unauthorised and untrained individual to attempt to do so since they would be putting not just themselves but others at risk as well.

For office electrical installation services, you must contact a commercial electrician who has the required experience and certification to carry out the job.

The costs may vary depending on several factors that include the size of your office, the number of appliances and equipment to install, and the accessibility of the wiring and cables.

While some electricians charge an hourly or day rate, some services have a fixed cost. The average cost of having your office rewired is usually around £2,500.

This is for around 5 to 8 days of work required to do a complete rewire of the property. This usually does not include any plastering or remodelling work that may be done to install the new cables.

Employers have a moral and legal responsibility to ensure that the workplace is safe for their employees and workers, and electrical safety is a huge part of that.

On average, around 1000 electricity-related accidents in the workplace are reported every year, with around 30 people dying from said injuries.

Although offices are low-risk environments when compared to other workplaces such as factories, warehouses, and construction sites, they still carry a considerable amount of risk.

All employers, under the Electricity at Work Regulations (1989) must make sure that all the electrics are properly installed and regularly inspected and maintained by a qualified electrician.

Electrical risk assessments should be carried out for all electrical hazards, detailing all those at risk, how the level of risk has been determined, and the precautionary and preventive measures to control them.

In addition to that, all the staff members and employees must be provided with adequate training on electrical safety.

Employers found not complying with the safety regulations carry the risk of huge fines, along with a tarnished reputation in the market for not caring enough for their employees and those in the office.

Therefore, it is essential to be aware of the electrical hazards, take action to immediately rectify them, have the electrical system installed by a professional, to begin with, and make sure they are regularly serviced and maintained.


Some common signs of faulty electrics and the need to get your office rewired or the installations fixed include:

Flickering lights

Lights will often flicker due to a number of reasons. It might be due to faulty installations, power disruption, power surges, or simply because they are about to burn out.

If it is one light only, it probably means that a single bulb needs to be changed. However, if the issue persists will more than one light bulb, it may be a clear indication of an underlying wiring issue that needs to be addressed.

Frequent outages

Circuit breakers are installed to identify power surges and overloading, and temporarily switching off the power supply to minimise risk to life and property.

While it is okay for them to trip once in a while, excessive tripping and outages might be a cause for concern. It is always best to call an electrician to get the circuit breaker and the rest of the installations tested to rule out any safety hazards.

Hot outlets

When outlets are pushing out more power than they are designed for, they can overheat and start an electrical fire. This may not just burn the socket but also damage any equipment connected to it.

Another reason for this issue could be faulty wiring in the office that is causing the outlets to heat up. To avoid this issue, you must never overload any sockets with more power than they can bear, make sure all the electrical appliances are compatible with your electrical system and have a professional check out the wiring on your property.

Strange odours

If you ever smell weird odours in the office, especially ones that smell like burning plastic, do not ignore them under any circumstances.

These smells are warning signs that something, most likely the wiring behind the walls, is burning. If that is the case, you must immediately turn off the power supply and call a certified professional electrician to conduct an inspection and fix the issue ASAP.


Under the Electricity at Work Regulations, you have a legal responsibility to keep all your electrical installations in a safe condition for your employees, clients, and visitors.

The best way to determine whether your office electrics are safe for use is through regular inspection and maintenance. This is done by carrying out an Electrical Installation Condition Report (EICR) at regular intervals, which can range from 3 to 5 years.

According to the National Inspection Council for Electrical Installation Contracting (NICEIC), two kinds of electrical installation checks must be carried out by a professional electrician to ensure everything is working as it should. They are:

Visual inspection

A visual inspection is carried out to inspect any visible signs of damage or defect, after which a Visual Inspection Report (VIR) is generated. The report provides a general summary of the electrical installation’s health by recording all the observations and recommendations.

During a visual inspection, an electrician is likely to check the fuse board, sockets, lights, plugs, switches, cables and leads, earthing and bonding, visible signs of wear and tear, and burning, as well as the kitchen and bathroom safety.

Detailed inspection

A detailed inspection refers to an extremely thorough check that identifies any damages, defects, or deterioration that may have been missed in the initial checks.

It involves testing all the circuits, appliances, machinery, and installations around the office, with the main purpose of determining whether the current installations are satisfactory for continued use or not.

An EICR (Electrical Installation Condition Report), which is more detailed than a visual report, is made at the end of the inspection. It is basically a detailed summary of the conditions of the electrics in the office and whether they comply with the current British Standards for electrical safety.


Once the EICR check is completed, a certificate of the electrical installation is provided, classifying the condition of the installation into three codes:

  • Code C1: indicating that danger exists and immediate action is required.
  • Code C2: indicating that, while the observation is not considered to be dangerous at the moment, it could become a real and immediate danger if a fault or other foreseeable event was to occur.
  • Code C3: indicating that, while the observation is not considered to be dangerous at the moment, improvements would contribute greatly to the overall health of the system.


When it comes to electrical safety, it is a crucial part to train the office workers and employees regarding the best practices.

They are an integral part of the office environment and the way they use the office electrics can have a huge impact on not just their safety but also those around them.

Some common considerations to follow include:

  • Making sure no outlet is overloaded,
  • Not plugging extension cords into other extension cords, and avoiding using them altogether,
  • Ensuring all the appliances and machines in the office are double-insulated and properly grounded,
  • Not using any equipment or electrical devices with wet hands,
  • Making sure all appliances are in well-ventilated areas for proper heat dispersion,
  • Never binding or knotting electrical cords,
  • Unplugging all the devices and electrical equipment when not in use to save energy and eliminate the risk of fires,
  • Have all the installations checked and maintained by a competent electrician,
  • Immediately cutting off the power supply in case of an emergency,
  • Ensuring the fuses and consumer units are installed correctly and functional at all times,
  • Checking the fixed installations for visible signs of damage, defects, and deterioration,
  • Never ignoring any signs of damage or malfunction and reporting them immediately,
  • Unplugging hot cords or plugs immediately and checking the wires and appliances for signs of damage,
  • Placing a clear sign that says “DO NOT USE” on faulty equipment and removing it from its working location until it is fixed or can be removed permanently,
  • Keeping flammable materials and water away from electrics,
  • Unplugging electrical cords by properly gripping the plug and never by pulling it with force,
  • Removing any electrical cords from high-traffic areas to eliminate the risk of tripping and damage to the cords,
  • Ensuring all pieces of equipment and machinery are from reliable brands and safe to use,
  • Disconnecting all pieces of equipment and machinery before cleaning or servicing,
  • Even if you have a surge protector, having an electrician test the circuit’s efficiency in handling the load,
  • Never connecting two high-wattage appliances to an outlet even if it can supply power to multiple appliances,
  • Knowing and following the course of action in case of an electric shock,
  • Knowing how to operate a manual fire alarm system in case of a fire,
  • Calling the fire and rescue services immediately in case of an electrical fire.
