Household electrical problems
Find the cause before choosing the repair.
The same symptom can have several causes. Electrical testing and diagnosis help establish whether the problem lies with an accessory, an appliance connection, fixed wiring or protective equipment, rather than replacing parts on a guess.
Fault investigation is part of our domestic electrical services. Our guide to common electrical problems in homes explains some of the warning signs homeowners encounter.
Symptoms to discuss
Tripping, loss of power and unreliable fittings.
- Circuits that keep tripping
- An RCD can operate when it detects current leaking from its intended path. A circuit breaker may trip because of an overload or short circuit. The cause could involve an appliance, wiring or another part of the installation; the device that trips is not necessarily faulty.
- Sockets and switches
- A socket that stops working or a switch that works intermittently needs investigation. Loose connections, damage and other faults can affect operation. Do not assume a non-working socket is disconnected from the supply.
- Lighting problems
- Flickering lights, lights that fail together or a lighting circuit that trips can have different causes. Inspection and testing help distinguish a fitting or control problem from a fault elsewhere on the circuit.
Safety first
Leave electrical investigation to a professional.
Stop using affected sockets or equipment if you notice burning smells, scorch marks, sparking, unusual heat or buzzing. Do not keep resetting a tripping RCD or circuit breaker, bypass protection or attempt work on live wiring.
Do not remove covers, touch damaged wiring or use water near an electrical fault. Arrange urgent professional help for signs of danger. If there is a fire, get out, stay out and call 999; do not wait for an enquiry-form response.
Read NICEIC's socket safety guidance for further information on warning signs.
When the wider installation needs review
A fault does not automatically mean the fuse board needs replacing. Where findings point to damaged equipment or unsuitable protection, we discuss the assessment and options. Our consumer unit replacement page explains that process.
Where a broader condition assessment is appropriate, an Electrical Installation Condition Report (EICR) serves a different purpose from investigating a specific fault. The appropriate scope depends on the installation and the concern.
Investigation and repair
From symptoms to an agreed next step.
Describe what happens
Tell us which rooms or circuits are affected, when the problem occurs and whether anything changed beforehand. Share observations you already have; do not recreate a fault or dismantle equipment to investigate.
Inspect and test
We assess the affected installation and carry out appropriate electrical testing, using safe isolation where needed. Access to sockets, fittings and the consumer unit may be required, and the supply may need to be interrupted.
Explain the findings
We discuss the identified fault, any limitations and proposed repairs. Intermittent problems can need further investigation, so the next steps and scope should be agreed rather than assumed.
Agree repairs and check the work
Any repair work is discussed before proceeding. Relevant inspection and testing follow the work, with documentation appropriate to what has been carried out.
Scope and cost
What affects the investigation cost?
- The fault and affected circuits
- A fault limited to one accessory can involve different investigation from an intermittent issue affecting several circuits. Symptoms alone do not establish the repair needed.
- Access and existing information
- Access to the installation, property layout and previous electrical records can influence the investigation. Let us know about access restrictions when enquiring.
- Further investigation and repairs
- Parts, remedial work or additional testing may be needed once the cause is understood. Discuss how investigation is charged and how any further work will be agreed.

Electrical fault finding questions
Why does my RCD or circuit breaker keep tripping?
Possible causes include an appliance fault, damaged wiring, leakage or an overloaded circuit, depending on the protective device. Repeated tripping needs professional investigation. Do not keep resetting the device or bypass its protection.
Can I investigate a faulty socket myself?
Do not remove socket covers, open the consumer unit or work on wiring. A socket can still be live even when it does not work. Stop using affected equipment and arrange professional inspection, especially if there is heat, damage, buzzing or a burning smell.
What should I tell you before a fault-finding visit?
Share your postcode, the symptoms, affected rooms or circuits and when the issue occurs. Previous electrical reports and details of recent work may help. Only share information you can obtain safely without testing or dismantling anything.
Does electrical fault finding include an EICR?
Fault finding investigates a particular problem. An EICR assesses the condition of an existing installation within an agreed scope. They serve different purposes; we can discuss whether a wider condition inspection would be useful.
Will a tripping circuit mean I need a new consumer unit?
Not automatically. The cause may be an appliance, accessory or circuit fault. The consumer unit and its protection should be assessed where relevant, with any replacement recommendation based on the findings.
What affects electrical fault finding cost?
The symptoms, number of circuits, access and extent of investigation affect the cost. Any repair parts or additional work should be discussed separately once the findings are known. Contact us to discuss the problem and charging arrangements.
