Build the circuit history
The technician compares what stopped working with the consumer-unit labels and the customer account. Recent changes help establish a sensible starting point.

The diagnostic path used for Willesden properties
At a Willesden booking, the technician first separates a supply issue, an appliance symptom and a fixed-wiring fault. The rooms affected, recent changes and the timing of each trip create the test plan before instruments are connected.
Isolate and prove safely
Protective devices, circuit labels and accessible connections are reviewed so measurements relate to the correct wiring rather than a neighbouring circuit.
Test in a controlled order
Continuity, insulation resistance and other appropriate readings are used to reduce the possible causes. Results are compared across circuit sections where access allows.
Agree what follows
Final checks confirm the condition at handover. Any limitation, inaccessible section or monitoring advice is recorded so the next decision is based on evidence.
Guide costs for tracing a fault in Willesden
A Willesden visit may stop after one clear finding or continue through several circuit sections. The technician confirms the diagnostic boundary before extended testing is added.
Initial diagnostic visit
From £105Reported-symptom review, consumer-unit checks and focused testing of one accessible circuit.
Extended circuit tracing
From £175Additional test points or circuit sections where the first readings do not isolate the cause.
Multi-circuit investigation
From £259Broader testing, return diagnostics or coordinated access across more than one affected area.

Electrical Fault Finding FAQ for Willesden
Answers are visible in the HTML without opening an accordion or running JavaScript.
Is an EICR the same as fault finding?
No. An EICR assesses the condition of an installation against inspection and testing requirements. Fault finding is a focused investigation into a reported symptom or specific circuit problem.
Will the power be switched off during testing?
Usually the affected circuit must be isolated for safe tests, and some checks may briefly affect adjacent circuits. Essential equipment and occupied areas should be mentioned before work starts.
Do landlords receive the test findings?
The tested area, findings, limitations and recommended next step can be recorded for the responsible person. Access and authority for remedial work should be arranged before the booking.
Does fault finding include the final repair?
The diagnostic visit identifies the likely cause and safe repair route. A simple accessible correction may be possible, but parts, concealed access and larger remedial work are confirmed separately before they are added.
