Electrical faults can be frustrating, inconvenient and potentially dangerous. Invisiwire provides expert electrical fault-finding services across Wiltshire, using professional diagnostic equipment and years of experience to trace problems to their root cause quickly and accurately.

Our fault-finding service covers everything from tripping RCDs and power loss to intermittent faults, earth leakage and appliance issues. We do not just treat symptoms, we identify the underlying cause so the problem stays fixed. Every diagnosis is followed by a clear explanation and a transparent repair quote.

We use professional multimeters, insulation resistance testers, loop impedance testers, thermal imaging cameras and cable tracing equipment to locate faults with minimal disruption to your property. Most faults are identified and repaired in a single visit thanks to our well-equipped vans and experienced electricians.

Do not ignore persistent electrical problems. Tripping circuits, flickering lights, warm sockets and buzzing sounds can indicate serious underlying issues that need prompt professional attention. Our fault-finding team serves homes and businesses throughout Devizes, Calne, Melksham and all Wiltshire areas.

Common Questions

Electrical Fault Finding FAQs — Understanding Your Electrical Problem

Random RCD tripping is usually caused by an earth leakage fault somewhere in your installation or an appliance. Common causes include moisture in sockets or switches, damaged appliance insulation, neutral-to-earth faults, or cumulative small leaks from multiple appliances. Our fault-finding service traces the exact source.

We charge a transparent call-out and diagnosis fee, which we quote before dispatch. Most common faults are then inexpensive to repair once identified. We always quote the repair cost separately and only proceed with your approval.

In most cases yes. We use thermal imaging, cable tracing, insulation testing and selective circuit isolation to pinpoint faults with minimal disruption. Only if the fault is inside a buried cable may we need limited access, which we discuss with you first.

Note when the fault occurs, which circuits are affected and any recent changes such as new appliances or decorating. If safe to do so, try to identify which circuit breaker trips. This information helps us diagnose faster.

We guarantee our repairs for 6 years under the NAPIT warranty scheme. By fixing the root cause rather than the symptom, the vast majority of faults stay resolved. If a related issue arises within the warranty period, we return promptly to resolve it.

“Called up to ask about a fuse in the main fuse board as we went through a power tool cable and instead of coming out to look he very kindly talked us through finding a fuse along the route of the cable and we managed to swap it out and sort the issue, no stress, nothing to pay for his time over the phone! Couldn't ask for a better person.”
