Electrical Thermal Imaging Surveys

Our services

What is thermal imaging?

Thermal imaging, also called thermography, uses infrared cameras to capture temperature patterns on electrical, mechanical, and building elements. It highlights heat anomalies that are invisible to the eye, allowing faults to be found early and corrected before they cause failures, fire, or costly downtime. As part of a planned maintenance programme, thermal imaging supports safer operations, better reliability, and clearer evidence for compliance and insurance.

Why choose Complii?

How we can help.

Protect your people, property, and business. Here’s why we’re the right choice for thermal imaging.

Early fault detection

Identify loose connections, overloaded conductors, imbalanced phases, failing bearings, and insulation defects before they escalate. Targeted fixes reduce the chance of arcing, overheating, and unplanned outages.

Reduced disruption and cost

Thermal surveys are non contact and usually completed while systems remain energised and in service. This limits shutdowns, shortens investigation time, and helps you schedule remedials efficiently.

Clear, prioritised reports

You receive image sets with temperature deltas, locations, and severity ratings, plus practical recommendations. Findings are prioritised so you can act on the highest risks first.

Safer people and property

By addressing hotspots promptly you lower the risk of electrical fires and equipment damage. This protects staff, visitors, plant, and critical processes.

Better compliance evidence

Thermal imaging supports duties under the Electricity at Work Regulations and your fire safety management by demonstrating proactive inspection and maintenance. Reports provide a useful audit trail for insurers and regulators.

Wider performance insight

Beyond electrical panels, thermography helps diagnose issues in HVAC, boilers, pumps, and building fabric. It can reveal missing insulation, air leakage, roof moisture ingress, or blocked coils that drive energy waste.

Your questions answered.

Not specifically. However, the law requires that electrical systems are maintained to prevent danger. Thermal imaging is a practical way to evidence proactive inspection, and it is often requested by insurers and clients as part of a preventive maintenance regime.
Complete a baseline survey after installation or major works, then repeat at agreed intervals based on risk. Many sites schedule annual checks, with more frequent surveys for critical or high load equipment.
Yes, most electrical thermal inspections are completed with equipment energised and under load so hotspots can be observed. A load of at least forty per cent is typically recommended for meaningful results.
Surveys are non intrusive and planned around your activities. Isolations are rarely required for imaging itself. If any intrusive checks or repairs are needed, we will agree safe access and timing with your team.
Common scopes include switchboards, MCCs, distribution boards, busbars, control panels, UPS systems, transformers, motors and bearings, boilers and flues, pumps, and HVAC equipment. Building surveys can include roofs, façades, doors, and chilled spaces.
Expect thermal and visual images, temperature readings and differentials, asset references, locations, severity grading, and recommended actions. We also advise on retest intervals and any conditions that may have affected readings, such as load or ambient temperature.
