Commercial electrical services we take on
Our commercial electrical services cover planned work in non-domestic buildings, priced after a free visit:
Lighting
Commercial lighting installation in offices, shops and the communal areas of blocks.
Power
Sockets and new circuits when an office is refurbished or a room changes use.
Fault finding
Tracing why a circuit keeps tripping, then repairing it.
Electrical maintenance
Periodic inspection and testing of the fixed wiring, with a written report, the EICR (Electrical Installation Condition Report); our EICR certificates page explains its codes.
New cables often leave chases (channels cut into a wall) and holes in ceilings. Our own team fills, skims and repaints them.
Your duty to maintain the electrics
If you're an employer or self-employed, the Electricity at Work Regulations 1989 apply to the electrical systems within your control. Regulation 4(2) requires that, as may be necessary to prevent danger, systems are maintained so as to prevent that danger, so far as is reasonably practicable.

Regulation 4 sets no interval. HSE's guidance (HSR25) calls inspection and, where necessary, testing an essential part of any preventive maintenance programme.
How often is for the dutyholder (here, the employer or self-employed person in control of the system) to judge, using all the information they need, including experience of use and the manufacturer's guidance. Records aren't a legal requirement, but they can help show you have complied.
Any part of an installation that becomes obviously defective between tests should be switched off until the fault is fixed (HSE's electrical safety FAQs).
Offices, blocks, churches, gyms and shops: the electrical side
Offices
Lights and sockets moved or added when the layout changes; a full refit is an office fit out.
Blocks of flats
The landlord's lighting in stairs and corridors; the rest of the common parts is work for social housing contractors.
Churches
Lighting in naves and halls, where high ceilings make access part of the job.
Gyms
Lighting across the training floor and power for the equipment.
Shops
Display lighting, and sockets for counters and tills.
From 30 November 2026, Awaab's Law will also cover electrical hazards that present a significant risk of harm in social homes; our guide to Awaab's Law sets out what that means.

Electrical work for buildings in use
HSE's guidance prefers electrical work to be done with the conductors made dead first, which means switching off the circuits involved. In a building that stays open, that has to be planned with whoever runs it:
- which circuits go off, and for how long;
- what must stay on, such as tills, servers, fridges or the stair lighting in a block;
- which areas close while the work is done.
The wider programme, and your duties as a client under CDM (the Construction (Design and Management) Regulations 2015), are on our commercial construction page.

Frequently asked questions
Call 020 8249 7303
What does a commercial electrician do?
Commercial electricians, or electrical contractors, install, maintain, inspect and repair the electrics in non-domestic buildings: lighting, sockets and circuits, fault finding and periodic testing, usually in buildings that stay open while they work.
Do commercial premises need an EICR?
Regulation 4 of the Electricity at Work Regulations, which includes the duty to maintain the electrics, names no report and sets no interval. HSE says installations should be tested often enough that there is little chance of deterioration leading to danger, and an EICR (Electrical Installation Condition Report) is the usual record.
Can you light the communal areas of a block?
Yes: stairs, corridors and entrances, which normally run on the landlord's supply rather than the flats'. If the common parts are being redecorated too, our own team paints them once the lights are in.
What makes one commercial electrical job cost more than another?
The number of lights, sockets and circuits; how easy the cable routes are to reach; how much of the building must stay powered while we work; the testing and certificates needed; and how much plaster and paint has to be made good.
