24-hour emergency line
24-hour emergency repairs for shops and commercial premises in London
A shutter that will not close, a leak over the shop floor, no power, a smashed shopfront, a door that will not lock: call 07852 224644 at any hour. MAINTSUPP takes the call, tells you the realistic attendance time, sends a vetted contractor to make the site safe, and arranges the permanent repair.

What we attend
The faults that cannot wait until morning
Emergency maintenance is reactive maintenance at its most urgent: the first visit makes the site safe, and the repair is finished after it.
Shutters and doors
Roller shutters stuck open or closed, doors that will not lock, failed closers and damaged entrances secured, and the shutter repair followed through.
Electrical faults
Loss of power, tripping boards, burning smells, failed lighting and unsafe illuminated signs made safe by qualified electrical contractors.
Leaks and floods
Leaks through ceilings, burst pipes, and blocked toilets and drains contained and repaired by a commercial plumber.
Glazing and shopfronts
Smashed or cracked shopfront glass made safe by emergency boarding up, with a glazier arranged to replace the pane once it is measured.
Locks and security
Lost keys, snapped keys, forced locks and break-in damage secured by a commercial locksmith.
Heating, cooling and refrigeration
Air conditioning, heating and display refrigeration failures attended, with stock-at-risk faults put first.

Questions
Emergency repairs: what people ask
Is the emergency line answered 24 hours a day?
Yes, for commercial premises in London. Call 07852 224644.
How quickly can somebody attend?
It depends on the trade, where the site is and the time of night. We give you the realistic time on the call, before you commit. We do not promise a fixed arrival time, because nobody can honestly keep one across every trade and postcode.
What does an emergency call-out cost?
You are told how the call-out is charged before anyone is sent. Clients on a monthly coordination plan pay the out-of-hours fee published on the pricing page, and the contractor’s own charge for the work.
Do I need a contract to use the emergency line?
No. A single shop, kiosk, restaurant or office can call for a one-off emergency.
Will the repair be finished on the first visit?
Not always. The first job is to make the site safe and secure. Where a part, a pane of glass or a second trade is needed, the permanent repair is arranged and followed through.
Can you attend inside a shopping centre at night?
Yes. Access is arranged with the centre’s security or management team, who control entry outside trading hours.
Do you attend homes?
No. MAINTSUPP works for commercial premises only: shops, kiosks, restaurants, offices, gyms and clinics.
