Fault Finding
We find the fault others give up on
Tripping RCDs, flickering lights, dead sockets and intermittent faults are frustrating and can be dangerous. Our engineers use systematic testing and proper diagnostic equipment to trace the root cause — not just guess — and then put it right and prove it’s safe.
Everything covered, done to standard
RCD Tripping
We isolate the faulty circuit or appliance causing nuisance tripping and resolve it for good.
Dead Circuits
No power to sockets or lights? We trace breaks, loose connections and failed accessories quickly.
Intermittent Faults
The hardest faults to catch — we use logging and methodical isolation to pin them down.
Burning Smells
Treat as urgent. We locate overheating connections and make the installation safe immediately.

Fault Finding — your questions answered
How long does fault finding take?
Most faults are located within the first hour using proper diagnostic testing. Intermittent faults can take longer, but we always explain what we’ve found and quote any repair before carrying it out.
Why does my RCD keep tripping?
Repeated RCD tripping usually points to a faulty appliance, moisture in a circuit, a damaged cable or an overloaded board. We isolate circuits methodically to find the exact cause rather than guessing, then put it right and prove the circuit is safe.
What our customers say
Booked Brightwell to fit a 7kW charger and they sorted the whole grant claim for me. Tidy, on time and explained everything. The app setup was done before they left. Couldn’t fault them.
Full rewire on a lived-in house. They protected the carpets, cleaned up every day and the making-good was spot on. Certificate came through two days later. Genuinely premium service.
Had the whole ground floor fitted with downlights and some extra sockets. The finish is immaculate — you’d never know walls had been chased. Polite, careful and great value.
