Hearing that a circuit has a low insulation resistance reading during a fusebox replacement can be worrying. The next step should be a clear explanation and investigation, rather than an immediate assumption that the whole property needs rewiring.
Find out what the result means
Insulation testing helps assess the separation between conductors and parts they should not contact. A poor result can involve damaged wiring, moisture, an accessory or connected equipment. The test arrangement also matters, so the cause needs confirming before choosing a repair.
Useful questions for your electrician are: which circuit is affected, what has been ruled out, and what investigation is needed next? A new consumer unit cannot repair a fault elsewhere in the wiring.
Agree the next step and charging basis
At Solid Electrics, electrical fault finding in Southampton is time-based because the cause and investigation time are initially unknown. Once the fault is understood, the repair options can be explained. Sometimes a local repair is appropriate; more extensive work should be supported by the findings.
Where safe and practical, unaffected circuits may be restored while the defective circuit remains isolated. Never reconnect a circuit that has been isolated because of a fault.
