Residential and commercial electrical fault finding
Electrical Fault Finding
Recurring trips, flickering lights or a circuit that has stopped working can have several causes. Tell Upkeepone what you have noticed and where the property is, so the team can assess the next step for fault diagnosis or repair.
A callback request does not confirm an appointment. Attendance, timing and any charge must be agreed after the scope and postcode are reviewed.
Electrical danger needs a safe first step
Keep clear of anything unsafe
If equipment, wiring or an installation appears unsafe, keep people away. Only switch it off if it is safe to do so, then contact a competent electrical professional. Do not remove covers or try to investigate exposed parts. If there is a fire or immediate danger to life, leave the area and call 999.
Describe what is happening
Signs you may need an electrician to investigate
You do not need to identify the cause. A clear description helps the team decide whether the enquiry needs electrical fault finding, a repair, an EICR or another service.
A breaker or RCD trips repeatedly
Say which part of the property loses power, when it happens and whether a particular appliance or activity was in use. Do not remove the consumer-unit cover to investigate.
Lights or sockets work intermittently
Describe which fittings are affected and whether the issue changes when equipment is used. Leave anything damaged, hot, buzzing or sparking alone.
Part of the installation stops working
Explain what has lost power, whether other areas still work and when the problem began. An apparent loss of supply may need a different service route.
A clear scope comes first
What electrical fault diagnosis may involve
Discuss the symptoms
The electrician needs to understand when the problem started, what equipment or circuits are affected and any changes that happened beforehand.
Assess access and safe isolation
The installation, occupancy, equipment and access can affect which checks are suitable. Tell the team about business hours, tenants and any supply restrictions.
Explain findings and next steps
The cause may not be clear until suitable checks have been completed. The electrician should explain the findings and agree the scope and price of any repair before additional work proceeds.
Some faults need an on-site investigation before a repair can be specified. A callback or an initial description does not confirm a diagnosis, a fixed price or that the repair can be completed in one visit.
A useful description saves a follow-up
What to include in your enquiry
Use the callback form to share the full postcode, whether the property is domestic or commercial, what stopped working and when you first noticed it. Mention any signs of heat, burning, visible damage or a protective switch operating. Do not approach damaged equipment or take photographs from an unsafe position.
For a workplace or rented property, include the site contact, access arrangements, permitted working hours, isolation restrictions and who can approve additional work. Tell us about previous checks or repairs if you have the records available.
Postcode-led attendance assessment
Electrical fault-finding coverage
London, Essex and Kent are priority areas for regular enquiries. Hertfordshire, Surrey, Buckinghamshire, Berkshire and Sussex are also covered. Other UK areas may be considered by request. Attendance depends on the postcode, the installation and fault, safe access, travel and an appropriately qualified engineer being available. Send the full postcode so the team can assess the request.

Competence should match the work
Electrical qualifications and records
Upkeepone states that its electrical engineers are qualified for the work they undertake, with NAPIT or NICEIC registration where applicable. Ask which qualifications and registration are relevant to your particular fault and the proposed work.
The checks, repairs and paperwork depend on the scope. Fault finding is not the same as an Electrical Installation Condition Report (EICR). If you need a report on the condition of a fixed installation, choose the relevant domestic and landlord EICR or commercial EICR service.
Read HSE advice on unsafe electrical installations and competent work. If you are choosing a contractor, Electrical Safety First explains how to find a registered electrician.
Answers before you ask us to call
Electrical fault-finding questions
What happens during electrical fault finding?
The electrician discusses the symptoms, checks what is affected and decides which investigation is suitable. The cause may only become clear after appropriate on-site checks. Any repair scope and price should be agreed before additional work proceeds.
Why does my circuit breaker or RCD keep tripping?
Several issues can cause a protective switch to operate, and the symptoms alone do not identify which one. Explain what loses power and when it happens. Do not remove the consumer-unit cover or handle exposed electrical parts.
Can an electrician diagnose the fault from my description?
A clear description can help the team assess the enquiry, but it cannot always show the condition or cause of a fault. An on-site investigation may be needed before a repair can be specified or priced.
Do you cover my postcode?
London, Essex and Kent are priority areas. Hertfordshire, Surrey, Buckinghamshire, Berkshire and Sussex are also covered; other UK areas may be considered by request. Attendance depends on the postcode, installation and fault, access, travel and appropriately qualified engineer availability.
How much does electrical fault finding cost?
The cost depends on the fault, checks required, time, access, parts and travel. Ask whether an assessment or call-out charge applies and what any quotation includes before agreeing to a visit. Upkeepone has not published a price for every fault on this page.
Can you investigate faults at a business or rented property?
Domestic and commercial enquiries can be considered. Tell us who can arrange access, site opening hours, tenant or site contacts, isolation restrictions and who can approve additional work.
Is fault finding the same as an EICR?
No. Fault finding investigates a reported symptom. An Electrical Installation Condition Report (EICR) is a formal report on the condition of a fixed electrical installation. Use the domestic or commercial EICR page if you need an inspection report.
Who should I contact for a power cut or an immediate danger?
For an apparent supply-network problem or wider-area power cut in Great Britain, contact 105. If there is a fire or immediate danger to life, leave the area and call 999. Keep away from unsafe electrical equipment; only switch it off if safe.
