Commercial electrician
Commercial electricians for shops and retail units in London
Lights out over the shop floor, a circuit that keeps tripping, no power to the tills or an emergency light that failed its test? MAINTSUPP sends a vetted, qualified commercial electrician to shops, kiosks, restaurants and offices across London — before opening or after closing, and at any hour in an emergency.

What we do
Electrical work for retail and commercial premises
A retail electrician is booked around the shop: before the doors open, after they close, or overnight inside a centre.
Faults and call-outs
Tripping circuits, loss of power to the tills or to a zone, faulty sockets, distribution board alarms and burning smells made safe and repaired.
Shop lighting
Lighting repairs, lamp and driver replacement, LED upgrades and display lighting, on the shop floor and in the stockroom.
Emergency lighting
Failed fittings replaced and the periodic emergency lighting tests scheduled, with the test record kept.
Sign power
Supplies to illuminated fascia signs and window displays repaired or installed.
Tills, kiosks and equipment
New circuits and sockets for till points, EPOS, fridges and displays, and the connection or disconnection of a kiosk.
Testing and certificates
EICR fixed-wire inspections, PAT testing and the remedial works arranged with qualified electrical contractors, and the certificates stored against the site.

Questions
Commercial electrician: what people ask
Do you employ the electricians?
No. MAINTSUPP coordinates vetted independent electrical contractors. We check their insurance and qualifications, brief them, follow the job and check the evidence before it is closed. You deal with one coordinator.
Can an electrician attend at night or before the shop opens?
Yes. Most retail electrical work is booked for before opening, after closing or overnight, and in a shopping centre that is normally a condition of the permit.
Is there a 24-hour emergency electrician for commercial premises?
Yes, in London. Call 07852 224644 at any hour. We tell you the realistic attendance time before you commit, and the first priority is making the site safe.
Do you carry out EICRs for shops?
The inspection and the certificate are carried out by qualified electrical contractors. We arrange the visit, chase the certificate, track any remedial works and record the next due date.
How much does a commercial electrician cost in London?
Each job is quoted individually, and you have the price before any work is booked. For an emergency you are told how the call-out is charged before anyone is sent.
Do you work inside shopping centres?
Yes. Works inside a centre are done under its own permit and access rules, usually outside trading hours. MAINTSUPP has already coordinated jobs inside Westfield Stratford City, Westfield London at White City and Brent Cross.
Do you take domestic electrical work?
No. MAINTSUPP works for commercial premises only: shops, kiosks, restaurants, offices, gyms and clinics.
