Thermal Imaging Surveys in Peterborough

Almost every serious electrical fault begins as resistance, and resistance under load means heat. A loose termination, a corroded connection, an overloaded circuit, an unbalanced three-phase supply, a motor bearing on its way out — each one shows as a distinct thermal signature long before it shows as a tripped breaker, a stopped line or a fire investigation.

A visual inspection cannot see any of this. The connection looks fine, the panel looks fine, and the first physical evidence is often scorching — which is to say, evidence that arrives too late. Thermography moves that discovery forward by months, while the fix is still a scheduled hour with a screwdriver rather than an emergency.

Thermal imaging is one of the few inspection methods that works best with everything switched on. We survey during normal operating hours, at normal load, without isolating supplies or interrupting production. Lines keep running, offices keep working, and in schools and care homes nobody loses power for a moment.

That makes it especially useful for premises where isolation is expensive or simply not an option: food-production and cold-storage sites, logistics operations, server and comms rooms, and any building where continuity of supply is part of the duty of care.

Some insurers now ask for periodic thermographic surveys of electrical installations at higher-risk premises, and many look favourably on them. Our reports are built for that audience: paired thermal and visual images of every anomaly, measured temperatures, a severity grading for each finding, and a clear recommended action with a timeframe.

The same document works as maintenance evidence under the Electricity at Work Regulations 1989, which require electrical systems to be maintained so far as reasonably practicable to prevent danger. A dated, graded thermographic survey is a straightforward way to show you are looking, not guessing.

An EICR assesses the condition of your installation against BS 7671 — and much of that testing is necessarily done with circuits isolated. Thermal imaging is the complement: it watches the same installation doing its actual job at full load. Each method finds faults the other cannot.

For critical premises — care homes, schools, industrial sites, anywhere downtime or fire risk is unacceptable — we recommend running the two together or on alternating visits. And because LS Elec carries out remedial works as well as inspections, one contractor takes you from finding to fix to re-survey, with no gap in between for the problem to grow.
