07 · Why the service matters

Why Urgent Electrical Rent Should Be Checked Promptly

Sparking, heat, burning smells, repeated tripping and exposed wiring can indicate an active fault. The affected circuit should be assessed before the area is used again.

An active electrical fault should not be left for a routine appointment. Sparking, burning smells, hot sockets, repeated tripping or sudden power loss should be reported to an emergency electrician in London.

Power loss and repeated tripping Repeated Tripping May Point to an Active Fault

A breaker, RCD or fuse that trips again after being reset may be responding to a fault on the circuit or connected equipment.

Affected circuit

The electrician checks which circuit has failed and what equipment is connected to it.

Protective device

The breaker, RCD or fuse is checked as part of the fault assessment.

Further testing

Testing may be needed before the circuit can be returned to normal use.

Where the protective equipment is damaged or unsuitable, a fuse box or consumer unit assessment can confirm the work required.

Heat, burning smells and damage Heat or Burning Smells Need Prompt Investigation

Heat, discolouration, burning smells or buzzing may indicate a loose connection, damaged accessory or deteriorated wiring.

Workd fittings

Cracked, loose or burnt fittings should not remain in use until they have been assessed.

Heat or discolouration

Heat, scorch marks or discolouration around an electrical point should be reported when you call.

Burning smell

A burning smell should be treated as an urgent warning sign, even if the circuit is still working.

When the cause is not immediately clear, our electrical fault finding service can locate the problem before the repair scope is agreed.

Sparking and exposed wiring Do Not Touch Sparking Equipment or Exposed Wiring

Visible sparks, arcing or exposed conductors can present an immediate risk. Keep clear and report exactly what you can see.

Keep clear

Keep people and pets away from the affected electrical point.

Do not touch

Do not touch exposed wiring, damaged fittings or equipment that is sparking.

Report the signs

Electrical Installation & Property Types Questions

Direct answers about urgent faults, warning signs, access, call-outs, repairs and costs in London.

The fault is assessed before repair work begins

The fault, access, installation condition, testing and parts can affect the work required and the final cost.

01What counts as an electrical emergency?

An electrical emergency may include sparking, burning smells, hot fittings, exposed wiring, repeated tripping or a sudden loss of power where safety or normal use of the property is affected.

02What should I do if I smell burning?

Keep clear of the affected fitting, do not continue using it and call with the location of the smell and any heat, smoke, noise or power loss you have noticed.

03Why does my RCD or circuit breaker keep tripping?

Repeated tripping may be caused by a fault on the circuit, damaged wiring or connected equipment. The cause should be diagnosed before the device is reset again.

04Can you help with a complete or partial power cut?

Yes. Tell us whether the full property or only certain rooms and circuits have lost power, and whether neighbouring properties are also affected.

05Is a hot socket or switch an emergency?

A socket or switch that feels unusually hot, smells burnt, buzzes or shows discolouration should be checked promptly and should not remain in use.

06What should I do if I see sparks?

Keep away from the affected equipment or fitting, do not touch exposed parts and call with a clear description of where the sparking occurred.

07Will you repair the fault during the call-out?

The electrician will assess the fault and make the area safe. A repair may be completed during the visit where the cause is accessible and the required parts and time are available.

08Will the electricity need to be isolated?

The affected circuit or part of the installation may need to be isolated for safe inspection and testing. Tell us about alarms, refrigeration, medical equipment or other essential supplies.

09What access does the electrician need?

Access is normally needed to the consumer unit, the affected room or equipment and any nearby areas required for safe testing.

10Can you attend an occupied or tenanted property?

Yes. Tell us who will provide access, which areas are occupied and whether tenants, staff or customers are present.

11What if the fault is caused by old wiring?

The immediate fault can be assessed first. If wider deterioration is found, we explain whether targeted repair or a separate rewiring assessment is needed.

12How are emergency electrician costs assessed?

The cost depends on the fault, access, time on site, testing, parts and any repair agreed after assessment.

13What details should I provide when I call?

Provide the postcode, affected area, warning signs, when the fault started, what has lost power and who can provide access.

14Should I keep resetting a tripping circuit?

No. If the breaker or RCD trips again after being reset, leave it off and call for the fault to be assessed.
