Fault Finding & Repairs
Fault finding is the systematic testing needed to trace an electrical problem back to its actual cause, rather than guessing. We isolate the affected circuit, test methodically, and give you a clear explanation of what was wrong and what we did about it.
When You Need Fault Finding
- An RCD, fuse, or circuit breaker keeps tripping and resetting it doesn't hold
- A socket or light has stopped working with no obvious cause
- You've noticed sparking, burning smells, or warm sockets and switches
- Power keeps cutting out intermittently in one area of the property
- An appliance trips the electrics every time it's switched on
Fault Finding Cost
£96–£212
This covers the diagnostic call-out; any repair work identified is quoted separately once we know what's wrong.
What affects the price?
- • How straightforward the fault is to trace
- • Whether it's an emergency (out of hours) or a scheduled visit
- • Any parts needed once the fault is identified
- • Access to the affected circuit, wiring, or consumer unit
How Long Does It Take?
Most faults are diagnosed within an hour or two on-site; straightforward repairs are often completed the same visit.
Regulations & Standards
Any repair or replacement work carried out is tested to BS 7671, and notified under Part P where the type of work requires it.
Frequently Asked Questions
Why does my RCD keep tripping?
An RCD usually trips because it has detected a genuine earth fault somewhere on the circuit — commonly a faulty appliance, damaged cable, or moisture ingress — and it needs tracing rather than just resetting.
Why does my fuse or circuit breaker keep tripping?
Repeated tripping usually means a circuit is overloaded, has a wiring fault, or a connected appliance is drawing too much current — we test the circuit to find the exact cause rather than just replacing the fuse.
Why is my plug socket sparking?
Sparking at a socket is a safety concern and usually points to a loose connection, damaged wiring, or a worn-out socket — switch it off and avoid using it, then get it checked before using it again.
How much does an electrician call-out cost?
A typical call-out for fault-finding costs around £96–£212 for the diagnostic visit; any parts or further repair work are quoted once the fault has been identified.
