What could be causing this?
A short circuit happens when two conductors touch without protection. Finding the exact point is the hard part — and that is exactly what our diagnostic equipment does.
Damaged insulation
Aged, chewed or pinched cables lose their insulation and let the conductors touch inside the wall.
Damp and water ingress
Water in junction boxes, sockets or outdoor light fittings creates the perfect path for a short circuit.
Faulty appliance
An appliance with an internal fault causes a short circuit every time it is plugged in.
Badly made connections
Improvised joints, worn insulating tape or old work done without technical rules end in a short sooner or later.
What to do right now, while the electrician is on the way
Simple steps to protect your home and your family
- 1
Switch off the main isolator
If there was a bang, a spark or smoke, switch off the main isolator on the consumer unit. It is the fastest way to remove the risk.
- 2
Unplug the suspect appliance
If the short happened when you switched an appliance on, unplug it and do not use it again until it has been checked.
- 3
Do not touch wires or blackened sockets
Even with the unit switched off, do not handle loose wires, melted sockets or areas that smell burnt.

Frequently Asked Questions
How do you find the source of the short circuit?
With professional diagnostic equipment, we test circuit by circuit from the consumer unit until we isolate the exact section — without opening walls unnecessarily. Then we repair the damaged point and test the whole installation.
Can a short circuit damage my appliances?
Yes. Until the cause is corrected, every attempt to restore power exposes your equipment to current spikes. That is why we recommend not insisting on resetting the unit and calling a technician straight away.
There is a burning smell but the lights have not gone out. Should I worry?
Yes — a persistent burning smell is often the warning that comes before a short circuit or the start of a fire. Switch off the circuit for that area and call us: we treat it as an emergency.
Do you fix it the same day, even at night or at weekends?
Yes. The emergency team operates 24 hours a day, 7 days a week. Outside normal working hours a different rate applies, which we tell you on the phone before we send a technician.
