Common Questions

Fault Finding FAQs
for Stevenage

How do I know if I have an electrical fault in my Stevenage property?+
Common signs of an electrical fault in a Stevenage property include: RCD or MCB tripping repeatedly, flickering or dimming lights, burning smells from sockets or switches, sparks when plugging in appliances, or circuits that simply don't work. If you notice any of these, contact us promptly.
Can you find intermittent electrical faults in Stevenage?+
Yes. Intermittent faults are among the most difficult electrical problems to diagnose because they don't occur every time. We use specialist test equipment and systematic circuit testing to identify the underlying cause of intermittent issues, even when the fault isn't actively present.
How much does electrical fault finding cost in Stevenage?+
Fault finding is priced based on the complexity of the fault and time required. We provide an upfront estimate before starting any work. Straightforward faults are typically resolved quickly. Complex or intermittent faults may require more detailed investigation. We will always agree a cost with you before starting.
My RCD keeps tripping in Stevenage — what should I do?+
A tripping RCD indicates an earth fault somewhere on the circuit it protects. Try unplugging appliances one at a time to identify if a specific device is causing the trip. If the RCD trips with nothing plugged in, there is likely a wiring fault. Contact us for a diagnosis — do not leave an RCD in the 'off' position for extended periods.
Can you carry out fault finding on solar systems in Stevenage?+
Yes. We diagnose and repair solar PV system faults including inverter issues, string failures, monitoring problems and MPPT faults. See our Solar Repairs page for more information.
