01
Describe the power problem
Notice the extent of the problem: the whole property, a group of rooms or one item. If a protective device repeatedly switches off, that pattern matters even when power returns between incidents. Heat, burning smells or crackling require a safety-led response rather than more attempts to operate the equipment.

02
Power loss, tripping circuits or overheating?
Use the power-loss page for a complete or partial outage. Use tripping circuits when the protection repeatedly disconnects the supply. Choose overheating electrics when there is unusual heat, discolouration or a burning smell. If symptoms overlap, describe them together rather than deciding that only one can be relevant.
03
What to tell an electrician about the fault
Tell the electrician when the issue started, what stopped working and whether any equipment or building work recently changed. Existing photographs or equipment information can help if already available safely. There is no need to open the consumer unit or reproduce a potentially dangerous fault to make the enquiry useful.
04
Electrical testing before repairs
The right repair depends on locating the problem. A network outage, a failed connection, an appliance fault and a circuit defect need different responses. Investigation can change the scope of the work, so discuss what is included initially and how findings, further testing and any proposed repair will be explained.
05
Request power fault investigation
You can ask for help without knowing the affected circuit name. A clear description such as upstairs sockets losing power is more useful than an uncertain technical diagnosis. Give the property use and any essential equipment affected, so access and interruption can be discussed when work is arranged.

Questions about power problems
Why might only part of a property lose power?
Different areas may be served by different circuits, and faults can affect only part of an installation. An electrician can investigate; the symptom alone does not identify the cause.
Can different symptoms have the same cause?
Yes. A connection or equipment problem can produce more than one symptom. Mention everything observed, especially heat, odour, visible damage or repeated disconnection.
What if I cannot identify the affected circuit?
Describe the rooms and equipment affected. Do not open or alter the consumer unit to identify a circuit. Any professional testing can be scoped from the information available.
