Intermittent Power in Swindon

We use thermal imaging cameras and power quality analysers to identify electrical faults that come and go. Our equipment records voltage fluctuations and electrical anomalies over time to pinpoint problems that occur when you're not looking.

Many intermittent faults only show up when circuits are working hard. We test your electrical systems under realistic load conditions, simulating normal household usage to trigger faults that might otherwise remain hidden.

All diagnostic work follows BS 7671 wiring regulations. We provide detailed test certificates showing insulation resistance, earth fault loop impedance, and RCD testing results to identify circuits that don't meet current safety standards.

You'll receive a written report documenting what we found, which circuits are affected, and recommended repairs. We photograph problem areas and explain the likely causes, whether it's loose connections, damaged cables, or overloaded circuits.

Much of Swindon expanded rapidly in the 1950s-70s to house railway workers. These properties often have original wiring that's now 50+ years old, with rubber or early PVC cables that become brittle and develop intermittent faults at connection points.

Many Swindon homes have had extensions, loft conversions, or kitchen refits without upgrading the electrical supply. Ring main circuits designed for 1960s electrical loads struggle with modern demands from electric showers, induction hobs, and multiple appliances.

Underground supply cables can develop faults where they enter properties, especially in areas with clay soil that shifts during Swindon's wet winters. Water ingress causes intermittent earth faults that are difficult to locate without specialist equipment.

Neutral wires carry the return current and can work loose over time. This causes voltage fluctuations that affect LED lights and electronic equipment. The problem often gets worse as circuits heat up during evening peak usage, then improves overnight as connections cool.
