Simply Electrical Contractors
Simply Electrical Contractors provides 24-hour emergency electrical assistance across the UK. Call with the property postcode and a clear description of what has happened so availability and the right next step can be discussed.
Electrical faults can present a risk of electric shock, overheating or fire. If there is immediate danger, make sure nobody goes near the affected area, and switch off the electrical supply only if you can reach it safely. Do not remove covers or attempt a temporary repair yourself.
The visit focuses on locating the source of the problem, making the installation safe and explaining any follow-on work that may be required. Availability and arrival timing depend on location and current call-out demand.
Warning signs
Some electrical problems are an inconvenience and others are a warning. These are the ones worth a phone call straight away, whatever the hour.
The neighbours still have lights, but part or all of your property has gone dead and the switches in the consumer unit will not stay on.
A protective device that cuts out again the moment it is switched back on is doing its job. Something on that circuit is wrong.
Overheating electrical parts often give off an acrid or oddly fishy smell. Treat it as a warning even when nothing looks damaged.
A faceplate that feels warm, shows brown marks or buzzes usually means a loose connection or an overloaded circuit.
Visible sparking, a crackle from a fitting, or lights dipping in several rooms at once all need checking before the circuit is used again.
A leak through a ceiling light, a flooded floor, or a cable or fitting that has been cut, crushed or left with live parts showing.
Not sure whether it is urgent? Call and describe it. If the problem can safely wait, planned fault finding is usually the better route. See fault finding.
While you wait
A few calm steps lower the risk while an electrician is on the way. None of them need tools, and none involve taking anything apart.
Fire, smoke or someone hurt?Get everyone out and call 999 before anything else. If a person is still touching the source of an electric shock, do not touch them. Switch the power off at the main switch if you can reach it safely.

Before you call
You do not need every answer to make the call, but each of these helps us judge the urgency and arrive prepared.
The full postcode, the type of property and how to get in: entry codes, parking, a concierge or a key holder.
What stopped working, anything you saw, heard or smelt, and whether it followed a leak, building work or a new appliance.
Which switches are down, whether they will reset and what has already been turned off. A photo helps if it is safe to take one.
Mention medical equipment, vulnerable occupants, freezers, servers, alarms or anything else that cannot be left without a supply.

The call-out
Every emergency visit follows the same order, so safety always comes before repair.
We take the postcode and the symptoms, talk you through anything that needs doing straight away and tell you whether an electrician can attend and roughly when.
On site, the electrician isolates the affected circuit and tests it, tracing the cause instead of guessing at it.
The dangerous part is repaired or disconnected so that as much of the property as possible can go back into use.
You are told what was found, what has been done and whether any further work is recommended.
When a full repair needs a second visit Some repairs depend on a part that has to be ordered, or turn out to be a larger job. The installation is left safe and the next step is agreed before the electrician leaves.
Property types
The fault may be the same, but who needs to know and what has to keep running differs from one building to the next.
Houses, flats and maisonettes, including converted buildings where supplies and meters are shared.
Calls from landlords, letting agents and tenants. We can liaise with the owner or agent and explain what was found.
Trading premises where a loss of power stops business: tills, refrigeration, lighting, IT and signage.
Stairwell and corridor lighting, landlord supplies, plant rooms and door entry in managed buildings.
Call-out costs
No two emergencies are alike, which is why there is no single price on this page. These are the things that shape the figure.
Evening, overnight, weekend and bank holiday visits are normally charged differently from a weekday daytime call.
Travel, parking and how easily the electrician can reach the equipment all affect the time involved.
A failed socket is quick to identify. An intermittent fault hidden somewhere along a circuit takes longer to trace.
Replacement parts, and anything beyond making the installation safe, are separate from the call-out itself.
Ask for the rate when you ring Check what the visit will be charged at before an electrician sets off, and ask for any larger repair to be priced before it goes ahead.
Common questions
For anything not covered here, call the 24-hour line with your postcode and a description of the fault.
Yes. The emergency line operates 24 hours a day. Call with the property postcode and details of the fault so availability can be confirmed.
That depends on where you are and how many call-outs are already under way. You will be given a realistic estimate when you call, not a blanket promise.
Stay away from it and stop using that circuit. If the main switch is within safe reach, turn the power off, then ring the emergency line. Where there is smoke, flame or anyone at risk, call 999 first.
Yes. Repeated tripping can indicate a fault in an appliance, circuit or protective device. Avoid repeatedly resetting it and arrange professional fault finding.
No. When neighbouring properties are off as well, the fault is on the network. Call 105, the free national power cut line, to report it and get updates.
Often it is. Where a part has to be ordered or the job turns out to be larger, the installation is made safe first and the rest of the work is arranged separately.
Yes. Emergency call-outs cover homes, rental properties and commercial or industrial premises.
