Installations and alterations
A business premises usually asks more of its wiring than a house ever will. One unit might need several circuits, its own distribution board, task and display lighting, and dedicated supplies for machinery.
Commercial Electrical Repairs and Fault Finding
A fault costs you trading hours, and sometimes a good deal more. Our Maidstone team traces problems back to the cause rather than the symptom — resetting a breaker or swapping out a socket without finding out why it failed only buys you a few days.
We’re most often called out to:
- Loss of power across part of a building
- Breakers or RCDs that keep tripping
- Faulty sockets and switches
- Flickering, dim or dead lighting
- Burning smells, hot accessories or buzzing
- Damaged fittings and accessories
- Equipment that trips a circuit the moment it’s switched on
Distribution boards and consumer units
Larger premises rely on distribution boards to feed and protect separate areas and circuits. Boards age, and older protective devices often no longer meet what the building is being asked to do.If yours needs replacing, extending or upgrading, we'll survey the existing installation first and set out the options. That might mean a board replacement, upgraded protective devices, additional or altered circuits, improved protection — and testing and certification once the work is signed off.
Why your business needs an EICR
An Electrical Installation Condition Report is a full health check on your fixed wiring. Three reasons it earns its cost:
Safety. It picks up shock risks, overloaded circuits and deteriorating cable before they turn into a fire.
Compliance. It helps business owners and landlords meet their statutory duties on electrical safety.
Records. You get a dated, documented account of the installation's real condition — useful for insurers, auditors and anyone buying the business.As a general guide, commercial installations are inspected at least every five years. Your insurer, licensing conditions or a change of use may call for one sooner.
Electrical Work for Offices and Retail Premises
Shops and offices need wiring that quietly supports everything else: lighting, workstations, tills, display units, kitchen equipment and comms. We work in offices, shops and retail units, commercial buildings, landlord-owned property, small business premises and workshops — adding sockets and circuits, fitting lighting, making alterations, carrying out repairs and handling testing.
Planned maintenance
Problems are cheaper to find than to fix. A maintenance programme keeps small faults from becoming shutdowns, and spreads the cost across the year.Programmes typically cover periodic inspections, fault finding, lighting repairs, socket and switch replacement, distribution board checks, emergency lighting tests, testing and certification, and any remedial work that follows.
