How We Diagnose Faults

Systematic Circuit-by-Circuit Testing

We don't guess. Using insulation resistance testing, loop impedance measurements, and thermal imaging when needed, we isolate exactly which circuit has the fault and precisely where it is. This avoids the 'try replacing things until it works' approach that costs you more money.

Honest Pricing Before We Start

We charge a diagnostic fee that covers the first hour of testing. If we find the fault within that time (which we usually do), the repair is quoted separately and you decide whether to go ahead. No surprises, no pressure. If the diagnosis takes longer due to complexity, we'll explain why before any additional charges.

Permanent Fixes, Not Temporary Patches

When we find a fault, we fix it properly. That means replacing damaged cable rather than just taping a joint, fitting a new accessory rather than tightening a cracked one, and testing the entire circuit afterwards to make sure the problem is actually resolved — not just hidden.

Frequently Asked Questions

Expert Electrical Fault Diagnosis in Devon

Electrical faults are one of those things that get worse the longer you ignore them. A tripping RCD might be annoying, but it could also be telling you there's damaged cable somewhere in your walls. A buzzing consumer unit might mean a loose connection that's arcing and generating heat. We've attended hundreds of fault callouts across Devon, and the ones that end up costing the most are always the ones people left for months before calling.

The most common faults we see are nuisance tripping caused by degraded cable insulation (especially in properties with pre-1970s wiring), dead sockets caused by loose connections in back boxes, and intermittent faults that only appear when certain appliances are running. We carry professional multi-function testers and insulation resistance meters to every callout — no guesswork required.

Frequently Asked Questions

How much does electrical fault finding cost?

Fault finding starts at £80 plus VAT per hour. Most faults are diagnosed within 1-2 hours. Complex faults in older wiring systems may take longer. We provide a clear cost estimate before starting any repair work.

My power keeps tripping — what's causing it?

Common causes include faulty appliances, moisture in circuits, degraded wiring insulation, overloaded circuits, or a failing RCD. We use insulation resistance testing and thermal imaging to diagnose the exact cause.

Why are my lights flickering?

Flickering lights can indicate loose connections, overloaded circuits, voltage fluctuations, or a deteriorating neutral connection. Persistent flickering should be investigated promptly as it can indicate fire risk.

Is a burning smell from my electrics dangerous?

Yes — a burning smell is an emergency. Turn off the affected circuit immediately and call us on 07758 135 486. Burning smells indicate overheating connections, which can cause electrical fires.

Can you find faults in old wiring?

Yes, we specialise in fault finding in older installations including rubber-insulated, lead-sheathed, and VIR wiring. We use Megger insulation resistance testing and thermal imaging cameras to locate faults accurately.

How quickly can you attend an electrical fault?

For emergencies like burning smells, sparking, or total power loss, we offer same-day emergency attendance. For non-urgent faults, we typically schedule within 24-48 hours.
