Commercial Electrical Services

The TK3 team consists of dedicated and skilled staff that carry out a wide range of commercial electrical services.

We undertake a variety of commercial electrical assignments for offices, shops, warehouses and factories. We have a wealth of experience working in three phase large scale industrial environments offering services from emergency and routine maintenance through to installation work for new factories.

We understand that commercial electrical work needs to be carried out with an extreme level of care and it is imperative to:

1: Keep disruption to a minimum
2: Keep within budget and on schedule
3: Carefully plan all works whether it be new installs or maintenance precisely to avoid any inconvenience

We consider all of the above when carrying out the following types of commercial work:

1: Data cabling and networks
2: Maintenance works, both planned and emergency
3: Lighting and power installations
4: Periodic inspection reports
5: Fire alarm systems, including installation and maintenance

Whichever type of commercial electrical work it is you require, our knowledgeable staff can guarantee to meet your needs.

Our staff have all the necessary qualifications and accreditations needed to work successfully in the commercial sector, that combined with our vital experience will ensure all work is completed to the highest standard.

Commercial property rewiring

A full rewire of an existing property can be disruptive but sometimes is necessary to ensure the electrical installation is safe for use, there is nothing more important than that.

You would normally discover a rewire is necessary for certain reasons, such as:
1: Observations and discoveries made by others, possibly while work is being carried out at the property
2: Faults occurring due to old wiring, light fittings or sockets
3: As a result of an electrical installation condition report/periodic inspection report being carried out on the property

Sometimes you may find that not all of the installation needs rewiring, it may be that a partial rewire of certain faulty circuits and a panelboard upgrade could bring the installation up to current standards and ensure it is compliant with the current IEE wiring regulations (BS7671). The only way to establish the extent of rewiring needed would be to carry out an electrical installation condition report. We recommend having these reports carried out first to establish the condition of the existing electrical installation in terms of electrical safety.

If a full rewire is required it is best if at all possible to have it done while the premises is empty, but rewires whilst the premises is occupied are also possible.

The TK3 team will work with you in the event a rewire is needed to ensure it can be completed safely and promptly whatever the circumstances may be.

Our staff have all the necessary qualifications and accreditations needed to work successfully in the commercial sector, that combined with our vital experience will ensure all work is completed to the highest standards.

Panelboard upgrades

The current IEE wiring regulations state that all circuits that feed sockets, mobile equipment outdoors, all bathroom electrics and all cables buried in walls must have RCD protection. Most if not all cabling in this country is run in walls so therefore all circuits now need to have RCD protection, older panelboards do not have RCD protection. Any panelboards that do not have RCD protection should be upgraded to modern RCD protected panelboards to ensure the installation complies with current regulations.

RCD’s are the best protection we have to protect us from potentially bad or fatal injuries due to electric shocks, they are designed to protect us from electric shocks form faulty circuit equipment/appliances or wiring.

What is an RCD?
RCD stands for Residual current device, this is a safety device that protects against earth faults that could lead to risk of electric shock. It detects the integrity of a circuit rather than detecting overload. If there was a fault with an appliance, water ingress or overheating somewhere in the electrical installation or a damaged cable electrical current would flow where it shouldn’t and could therefore cause an electric shock, if a fault like this were to occur the RCD would automatically trip in milliseconds and would not reset until the fault has been rectified to protect us from the risk of an electric shock. Whereas an MCB (miniature circuit breaker) only works on overload so wouldn’t trip if one of the faults mentioned above were to occur, leaving you vulnerable to an electric shock and in danger.

Replacing your panelboard provides protection and safety in your home for you and your family. If you ever have significant electrical work carried out at your home such as a new circuit you have 2 options:

1) Upgrade your whole panelboard to accommodate the new circuit and all the existing circuits
2) Changing socket and switch faceplates
3) Install a separate small panelboard to ensure the new circuit installed has RCD protection to comply with current regulations

Fire alarm systems

Installing a fire alarm system in commercial premises is not just an investment in terms of complying with the current IEE wiring regulations but an investment in peace of mind and customer/staff safety.

Fire alarms, sirens, and call points need to be thoughtfully placed to make buildings as safe as they can be. For commercial properties with kitchens or rooms that are prone to forming smoke or steam, heat alarms are a useful option for preventing fire alarms from being inaccurately triggered.

Below are the typical types of fire alarm systems we recommend and regularly install:

1) Hardwired – Interlinked System
This system is a hardwired system that has its own dedicated electrical circuit at the panelboard, it ensures that all detectors will never ‘run out of battery’ as they are fed from the electrical supply the whole time. The only time the backup battery in the alarms would be used would be in the event of a power cut, so there’s no worry or hassle of changing the batteries. All alarms on the fire alarm circuit are also interlinked, this means that if one of the alarms were to activate they all do to ensure you will hear them!

The rule of thumb for these alarm systems is to install a fire alarm system on each level of the house (downstairs hall and upstairs landing), a heat detector in the kitchen to detect any heat from a potential fire and a CO2 detector near the boiler to detect any carbon monoxide. With this system in place you would be alerted very early if there was ever a fire at the property giving you time to vacate the property safely. It really is the best fire detector system you could have in your home

2) Hardwired – Radio Linked Fire Alarm System
This system is similar to system 1, but is used more as a backup or substitute to system 1. This system can be used when routes/access to the panelboard or between fire alarm systems is limited. With this system you would install the same number of detectors in the same places as system 1 but they do not need to be interlinked in the wiring sense or have their own designated circuit at the panelboard, all each alarm requires is a permanent feed form a local lighting circuit, the detectors are then linked together through radio waves after a simple programming procedure.

Whichever system you require our expert staff will carry out the installation with minimum disruption and hassle. We are more than happy to offer further advice to help you decide which system would be best for you.

Portable Appliance Testing

PAT testing is undertaken to comply with the requirements of the Electricity at Work Regulations 1989 where Regulation 4(2) states that “all electrical equipment shall be maintained so as to prevent danger.”

Portable, fixed, transportable, plugged or spurred, all equipment needs to be inspected, tested and maintained.

We only employ qualified electricians so we are enabled to carry out all necessary repairs to the power supply at the time of inspection, thereby minimising the number of items failing.

Faults and failures, where they do occur, are reported to your office immediately so that you are aware of any potential problems.

Electrical Installation Condition Reports

Hiding behind walls and within trunking, electrical wiring seemingly does nothing more than provide power to the devices and machinery on which your business relies, but in order for your organisation to remain safe and compliant with modern standards, a knowledgeable pair of hands will be required to ensure there aren’t any underlying issues.

The load placed on electrical wiring installations and the ageing of parts – combined with any alterations or additions made to the building itself – means more frequent testing may be mandatory. This is particularly the case if your premises are subject to licensing by the authorities or have high levels of public access.

Emergency Lighting Testing

We can provide you with annual and interim Emergency Lighting testing inspections and if required will replace any faulty components from our on van stock.

Usually done with the Fire Alarm inspection it can also be combined with your PAT testing, adding further value to the visit. The resultant report contains a full schedule of the component parts of the system, any observations of non-compliance that will need further attention and will detail the repairs that were completed on site.

Emergency lighting sits within business premises largely unnoticed – until it’s called upon. And, when the time arises for it to come into action, it needs to be ready to guide people to safety.

Additions and alterations

We operate strategically to ensure that whilst electrical work is being carried out at commercial establishments, disruption to the business it kept to a minimum. By setting up temporary power supplies, we’re able to deliver electrical solutions whilst businesses continue to operate.

We issue certificates upon completion of all jobs, allowing you to keep an up-to-date record of the electrical work that we’ve carried out for you. Certificates for smaller works can be a bit of a grey area and there are instances where a certificate may not generally be considered essential. These are some examples:

Small works that may not need certification

1: Changing light fittings ‘like for like’

2: Changing socket and switch faceplates

3: Installing additional light fittings

Small works that always need certification

1: Wiring and installing an additional socket on an existing circuit

2: Any additions/alterations in a special location, e.g. bathrooms

Electrical Installation Certificates

These are issues upon completion of any new circuits.

All electrical work completed by TK3 Electrical services is certificated.

The reports provide evidence of compliance with relevant legislation and are suitable for all building societies & banks, county councils and insurance companies.

Minor Works Certificates

A minor works certificate is a smaller version of an electrical installation certificate that is designed to cover smaller works. This involves testing the existing circuit that has been worked on and a copy of the minor works certificate will be issued to the client on completion of the work.

Our staff have all the necessary qualifications and accreditations needed to work successfully in the domestic and commercial sector, that combined with our vital experience will ensure all work is completed to the highest standards.
