About

Test Inc. is the UK’s leading provider of electrical compliance, inspection, and maintenance services across both High Voltage and Low Voltage networks. Headquartered in Harlow, we work with critical environments nationwide — from NHS Trusts and government facilities to global FM providers and private estates.

Our mission is to make electrical safety seamless, non-disruptive, and smarter. That’s why we developed Optima24, our exclusive technology that enables full electrical testing without switching off the power — a breakthrough for hospitals, data centres, and any 24/7 operational site.

We offer a wide range of services including thermographic and ultrasonic inspections, power quality analysis, arc flash risk assessments, emergency lighting compliance, PAT testing, ductor testing, and condition monitoring. All delivered with precision, speed, and zero compromise on uptime.

Our work has been featured internationally — including at the IEEE EIC Conference 2025 in Texas — and we collaborate with institutions such as the University of Strathclyde to keep innovation at the heart of what we do.

From power station to plug top, Test Inc. is redefining electrical compliance for the UK’s most essential infrastructure.
