Thermographic Surveys
Professional Thermographic Surveys
Electrical Testing UK provides thermographic surveys of electrical installations for businesses, facilities managers, and public sector organisations.
Thermal imaging identifies hidden heat patterns caused by issues such as loose or corroded connections, overloaded conductors, failing components, and load imbalances that standard testing may not detect. If left unresolved, these faults can lead to equipment failure, downtime, and fire risk.
Our engineers inspect distribution boards, switchgear, busbars, and cable systems under normal load using calibrated thermal cameras. We then provide a detailed report including thermal images, temperature data, and prioritised recommendations for any issues found.
How Our Service Works
Infrared Imaging Under Live Load Conditions
Surveys are carried out under normal operating load to accurately detect heat-related faults.
Calibrated Thermal Imaging Equipment
We use high-sensitivity, calibrated cameras to identify even minor temperature variations.
Prioritised Fault Reporting
Each issue is reported with a thermal image, temperature data, and a clear priority level for action.
All Electrical Infrastructure Covered
We inspect distribution boards, switchgear, busbars, containment, transformers, and UPS systems.
Remedial Work Directly Available
We can complete any required repairs in-house, including tightening, replacements, and overload corrections.
Thermographic Surveys for Every Industry
Thermographic surveys detect hidden heat-related faults in electrical systems operating under load, helping prevent failure, downtime, and fire risk.
- Commercial premises and distribution boards: Identify faults such as loose connections, failing components, and overloaded circuits in offices, retail, hotels, and multi-tenancy buildings before they cause disruption or damage.
- Industrial sites and switchgear: Detect overheating in high-load systems including switchgear, busbars, motor control centres, and cable terminations, with findings prioritised by risk and urgency.
- Public sector and healthcare buildings: Support compliance and safety in hospitals, schools, and local authority estates with clear reporting suitable for maintenance and asset records.
- Wider testing programmes: Integrate with EICRs, panel risk assessments, and PAT testing to provide a complete view of electrical condition, covering both compliance and developing thermal faults.
From Site Access to Prioritised Report
What conditions are required for a thermographic survey?
Surveys are carried out under normal operational load, typically at least 40% of maximum load, to ensure heat-related faults are detectable. We coordinate access with site teams to minimise disruption across all key electrical areas.
What happens during the inspection?
Our engineers inspect accessible electrical equipment, capturing thermal and visible-light images of any anomalies. For each issue, we record peak temperature, a reference temperature, and the temperature differential.
What does the final report include?
You receive a clear report with thermal and visual images, temperature readings, likely causes, recommended actions, and priority ratings for each issue, designed for easy use by facilities and maintenance teams.
Why Organisations Choose Our Thermographic Surveys
- Detects hidden faults: Identifies developing issues under load that conventional testing cannot detect, including loose connections, failing components, and load imbalances.
- Expert interpretation: Surveys are carried out by qualified engineers using calibrated thermal imaging equipment, ensuring accurate analysis of electrical systems.
- Remedial work available: Any issues found can be repaired in-house, including tightening connections, replacing components, and resolving overloads.
- Supports compliance and insurance: Provides documented evidence of proactive maintenance often required for insurers and compliance audits.
- Fully qualified in-house team: All surveys are completed by NICEIC-qualified engineers, with no subcontracting.
