I first met Gary several years ago when I needed some additional power sockets installing. Based on that first positive experience, I have since contracted him to complete a variety of jobs, including an air conditioning install, home EV charger install (Hypervolt), bespoke bathroom lighting and an emergency repair to a consumer unit (life saver at a weekend!). In all cases, the service has been excellent from start to finish. Everything was completed to an exceptionally high standard, with great attention to detail. Gary is professional, punctual and takes time to explain everything clearly. He takes real pride in his work and genuinely cares about delivering a high quality service. I wouldn’t hesitate to recommend him to anyone looking for a reliable, skilled, and trustworthy electrician. I’ll definitely be using him again for any future electrical work.Posted on Google![]()

We have used Gary's services numerous times. The latest project was a plant room installation where the gas boilers were being removed and replaced by heat pump renewable technology. His work is brilliant and has an eye for detail. Job completed as per the programme and we received all the relevant certification on completion. Perfect 👍Posted on Google![]()

I found Gary on a google search when we were having issues with our garage electrics. He fitted us in the same day and was very thorough trying to find the cause of the problem. I would definitely recommend and wouldn’t hesitate to use againPosted on Google![]()

Gary has been brilliant. He was really responsive, did a great job and kept me informed throughout so I understood exactly what was happening. He also went above and beyond helping to check and resolve a couple of pre-existing issues, which I really appreciated. Everything was done properly and left tidy afterwards. As a parent with two young children in the house, it was also really important that I felt safe and comfortable with the work being done and Gary was professional and trustworthy throughout. I’d definitely recommend him and will use him again in future.
Standards & equipment we use
GW Property Maintenance Ltd carries out every commercial electrical installation to BS 7671 18th Edition and in line with the Electricity at Work Regulations 1989. On construction and fit-out projects we also work within the Construction (Design and Management) Regulations 2015 and, where they apply, the Building Regulations. These are the core UK rules for commercial electrical installation. Distribution boards follow BS EN 61439, emergency lighting follows BS 5266-1, and cable, trunking and conduit are chosen for the building, including low smoke cable where it is needed in public areas. Every circuit is tested with a calibrated Megger multifunction tester before handover, and safe isolation uses lock-off devices and a proved voltage indicator. As a NICEIC Approved Contractor, we issue the Electrical Installation Certificate with full inspection and test results, so you have a clear record for your insurer, landlord and Building Control.
What is commercial electrical installation in Tonbridge?
Commercial electrical installation is the design, installation, testing and certification of the electrical systems in non-domestic premises, such as shops, offices, restaurants, workshops and new commercial units. It covers distribution boards, circuits, power, lighting, emergency lighting, containment and supplies for equipment. A good installation is safe, matches how you use the space and comes with the certificate your insurer, landlord and Building Control expect.
Key Takeaways
- Commercial electrical installation means designing, installing, testing and certifying the electrical systems in new or refurbished non-domestic premises.
- Every new installation is tested to BS 7671 and handed over with an Electrical Installation Certificate and schedules of inspection and test results, which we issue within 48 hours.
- Electrical work for a small shop or office fit-out typically takes one to five days, and larger projects are programmed around other trades.
- Employers and building owners must keep electrical systems safe under the Electricity at Work Regulations 1989, and construction work is covered by CDM 2015.
- Cost depends on the size of the premises, the supply and the equipment, so a free consultation and a written quote come first.

How does commercial electrical installation work?
The electrician first holds a consultation and site visit, checking the supply, space, equipment and your plans. A design and programme are agreed, covering circuits, boards, lighting and any out-of-hours work. Cables, containment, boards and fittings are installed with safe isolation, tested circuit by circuit and recorded. You then receive the Electrical Installation Certificate and test results, and any snags are put right.

Why does it matter in Tonbridge?
Tonbridge has a busy High Street of older converted buildings, offices near the station, restaurants and hospitality venues, and workshops and units on its trading estates. Many premises are fitted out for new tenants, and old wiring, undersized boards and outdated fluorescent lighting often need to be replaced or extended. Poorly planned electrics cause tripping, delays and failed inspections. A correctly designed installation and certificate keeps you open and protects your lease and insurance.

What affects the cost of commercial electrical installation in Tonbridge?
The cost depends on the premises and the work rather than one flat rate. The main factors are:
- Size of the premises: A small shop costs far less to wire than a large office, restaurant or unit with many circuits.
- Supply type and capacity: A single phase supply is simpler than a 3 phase supply, and some projects need extra capacity from the network operator.
- New build or refurbishment: Wiring an empty unit is quicker than working around existing services and finishes.
- Distribution boards: The number of ways, protective devices and labelling decide the cost of each board.
- Lighting design: LED panels, display lighting and emergency lighting vary widely in price, though LEDs reduce running costs.
- Containment and cable type: Trunking, tray and conduit, and low smoke cable in public areas, all affect materials and labour.
- Equipment supplies: Kitchen equipment, EV chargers, CCTV and air conditioning need dedicated circuits.
- Programme and other trades: Fit-outs and construction projects depend on the order and speed of other trades.
- Working hours: Out-of-hours or weekend work to keep you trading can cost more than daytime work.
- Certification and records: Testing, schedules and handover documents take engineer time but protect you at inspection.
- Making good: Plastering and redecorating after chasing or drilling are usually separate from the electrical quote.
A free consultation and site survey is the only way to give an accurate figure, since two premises can need very different amounts of work.
Why landlords and business owners in Tonbridge need this
Landlords often need a fit-out or reinstatement to be certified before a new tenant moves in, and commercial leases usually make the tenant or landlord responsible for the electrical installation. Business owners need the commercial electrical installation certificate for their insurer, and sometimes for Building Control at Tonbridge and Malling Borough Council. Under the Electricity at Work Regulations 1989, employers and building owners must keep electrical systems safe, and fixed wire testing is commonly recommended every 5 years for offices and shops. Premises with escape routes also need working emergency lighting to meet fire safety rules.
Why local matters for this service
Tonbridge sits on the River Medway, with a High Street of older converted buildings, offices near the station, hospitality venues and units on its trading estates. As local commercial electric contractors based in West Malling, we know how to work in older premises, route cable through solid brick walls and plan work around opening hours. Listed buildings and conservation areas can have extra rules on external fittings, and we will tell you if consent could be needed. Fire safety in commercial premises is enforced by Kent Fire and Rescue Service, so emergency lighting and escape route lighting are installed with that in mind. For commercial electric services in Tonbridge near the Medway floodplain, we use higher IP-rated fittings and raise equipment where we can.
