Electrical Work Planned Around Your Business
Commercial electrical work needs to be planned around opening hours, staff, customers, equipment and other trades. ZJ Electrical Services works with business owners, landlords, managing agents and contractors across Leyton, Waltham Forest and East London. Recent work includes this lighting upgrade for an optician’s premises, designed to improve illumination throughout the retail space while complementing the interior design and minimising disruption to the business. Our wider commercial work includes new circuits, three-phase distribution, containment, equipment power supplies, emergency lighting, EICRs, data cabling and workplace EV charging. As a NICEIC Approved Contractor, we test, certify and document completed work appropriately.
Commercial Fit-Outs and New Installations
Electrical installations for offices, shops, restaurants and commercial kitchens, including lighting, socket circuits and dedicated equipment supplies coordinated with the wider project programme.
Three-Phase Electrical Installations
Installation and upgrades of three-phase distribution boards, sub-mains and dedicated supplies for machinery, commercial kitchens and other high-load equipment. We assess the existing supply, earthing arrangement and electrical demand before work begins.
Commercial Lighting and LED Upgrades
Design, installation and upgrades of energy-efficient LED lighting for offices, shops, restaurants and other commercial premises. We specialise in dimming systems, lighting controls and resolving compatibility issues between LED fittings, drivers and dimmer switches, with work planned to minimise disruption.
Commercial EICRs and Electrical Testing
Commercial EICRs and fixed-wire testing for offices, shops, restaurants and other business premises. We provide clear reports identifying defects and required remedial work, helping business owners, landlords and managing agents keep their electrical systems safe and properly documented.
Workplace EV Charger Installation
EV charger installation for workplaces, commercial premises and fleet vehicles. Every project begins with an assessment of the existing electrical supply, earthing arrangement, maximum demand, cable route and charging requirements before the charger and protective equipment are selected.
Data Cabling Installation
Installation and termination of Cat6 and Cat6A structured cabling for offices, shops and other commercial premises, including data points, patch panels, data cabinets and containment. Cabling is neatly routed and clearly labelled. We can also install associated socket circuits and equipment supplies, reducing the need to coordinate separate data and electrical contractors.
Cable Containment Installation
Installation of commercial cable containment, including PVC and galvanised steel conduit, trunking, cable tray and basket for power, lighting and data systems. Containment is planned around the building layout and other trades, then installed neatly with appropriate support and capacity for the required cabling.
Emergency Lighting Installation and Testing
Installation, alteration and testing of emergency lighting for offices, shops, restaurants, communal areas and other commercial premises. We replace defective fittings, carry out functional and duration testing, and provide clear records to support ongoing maintenance and safety responsibilities.
Dimming and Lighting Control Systems
Design, installation and fault finding for dimming and lighting control systems in offices, shops, restaurants and other commercial premises. We specialise in matching LED fittings, drivers and controls for reliable, flicker-free operation, including dimmer switches, scene settings and programmable controls.
Air Conditioning Power Supply Installation
Installation of dedicated electrical circuits for air conditioning units in offices, shops, restaurants and other commercial premises, including suitable circuit protection, local isolation and final power connections. We assess the existing electrical supply and coordinate with the air conditioning contractor so the power is ready when the equipment is installed.
PAT Testing for Businesses
Portable appliance testing for offices, shops, restaurants, landlords and other commercial premises. Appliances are visually inspected and electrically tested, with clear records and labels provided to help businesses manage equipment safety and ongoing testing schedules.
Commercial Fault Finding and Repairs
Specialist fault finding and electrical repairs for offices, shops, restaurants and other commercial premises. We trace damaged wiring, intermittent faults, tripping circuits and loss of power, including problems previous electricians have been unable to locate, then explain the findings and complete or quote for the required repairs.
