Thermal Imaging Surveys for Electrical Systems
Detect overheating faults before they cause downtime, damage, or fire.
Live infrared inspections delivered by NICEIC-approved engineers across Nottinghamshire, Derbyshire, and the East Midlands.
Electroglow provides non-intrusive thermal surveys for distribution boards, switchgear, and industrial electrical systems — with clear reporting suitable for insurers, audits, and preventative maintenance planning.
Overview
Many electrical faults develop silently — long before they trigger a trip, outage, or fire risk.
Loose terminations, overloaded circuits, unbalanced phases, and failing protective devices often generate heat as an early warning sign. Thermal imaging allows these issues to be identified quickly, safely, and without shutdown.
Our NICEIC-approved engineers carry out calibrated infrared inspections to detect abnormal temperature rise across:
- Distribution boards and switchgear
- Control panels and motor starters
- Busbars and cable terminations
- High-load industrial power systems
Thermal imaging is performed during normal operation, providing real-world insight into system performance under load.
Surveys can be delivered as a standalone service or integrated within broader Maintenance & Compliance Services or alongside your Fixed Wire Testing (EICR) programme
Who This Service Is For
Thermal imaging is particularly valuable for:
Warehouses and logistics centres
Manufacturing and production facilities
Pharmaceutical and cleanroom environments
High-load commercial buildings
Facilities managers responsible for insurer compliance
Sites experiencing nuisance tripping or overheating concerns
If your operation depends on continuous power, thermal surveys provide early fault detection before failure occurs.
What We Deliver
Routine EICR inspections provide essential assurance that your electrical systems remain safe, compliant, and fit for continued operation.
Infrared scanning of live electrical panels and switchgear
Detection of hot spots, loose connections, and overload risk
Inspection of luminaires, batteries, and control systems
Annotated thermal imagery with temperature readings
Prioritised findings for corrective planning
Full written report suitable for insurers and audits
Optional remedial works and follow-up re-scanning
All surveys are carried out with minimal disruption and no requirement for shutdown.
Where required, corrective works can be supported through our wider Electrical Installation Services
Benefits of Thermal Imaging Surveys
Thermal inspections provide one of the most effective forms of predictive electrical maintenance.
Key benefits include:
Early fault detection before breakdown or fire
Reduced risk of unplanned outages
Improved reliability of distribution infrastructure
Enhanced safety for personnel and assets
Insurer-ready documentation and audit support
Targeted maintenance rather than reactive repairs
Thermal imaging strengthens operational resilience and long-term compliance control.
Why Thermal Imaging Matters
Electrical overheating is rarely visible during day-to-day operation.
Only infrared inspection can confirm whether connections, breakers, or conductors are operating within safe temperature limits under real load conditions.
For industrial sites, this level of insight is critical to preventing failure, downtime, and safety escalation.
How it Works
Clear. Non-intrusive. Fully documented.
Survey & Planning
Review of critical panels, loading conditions, and operational constraints.
Live Infrared Scanning
High-resolution thermal imaging carried out under normal operating load.
Analysis & Risk Classification
Temperature anomalies assessed and prioritised by severity.
Reporting & Recommendations
Annotated report issued with clear corrective actions.
Remedial & Verification (If Required)
Repairs completed and re-scanning available to confirm resolution.
Case Study
Thermal Imaging Survey — Phoenix Business Park, Hinckley, Leicestershire
Challenge:
A commercial unit at Phoenix Business Park required a thermal imaging survey as part of preventative electrical maintenance.
During live infrared inspection of the LV distribution panel, Electroglow identified a cluster of closely positioned contactors operating at elevated temperatures — with surface readings approaching 100°C.
Although the panel remained operational, sustained temperatures of this level presented an increased risk of premature component failure, nuisance tripping, and potential fire hazard if left unaddressed.
The client required a corrective solution without disrupting ongoing site operations.
Solution:
Electroglow provided a structured corrective approach based on thermal findings:
Repositioned and spaced contactors where possible to improve airflow
Increased separation between heat-generating components
Installed a dedicated cooling fan to the front of the LV panel to improve forced ventilation
Re-scanned the panel post-modification to confirm temperature reduction
All works were completed efficiently within a live environment, avoiding operational downtime.
Results achieved:
Peak operating temperatures significantly reduced
Improved airflow and thermal dissipation within LV panel
Reduced risk of component degradation and failure
Enhanced long-term reliability of switching equipment
Full thermal imaging report issued for compliance and insurer documentation

Frequently Asked Questions
Answers to common questions about our solar and EV solutions.
Do I need to shut down power for a thermal survey?
No. Thermal imaging is carried out under live operating conditions while systems are under normal load. This allows accurate temperature readings without interrupting production or isolating power.
How often should thermal imaging be carried out?
For most commercial and industrial sites, annual inspection is recommended as part of a preventative maintenance programme. High-load, critical, or continuously operating systems may benefit from more frequent surveys.
Are thermal reports suitable for insurers and compliance audits?
Yes. Reports include annotated infrared images, temperature differentials, identified risks, and prioritised recommendations — suitable for insurer review, internal compliance records, and audit documentation.
Can you repair issues identified during the survey?
Yes. Where overheating, loose terminations, or load imbalance are identified, we can carry out corrective works and provide follow-up thermal verification to confirm resolution.
Does thermal imaging replace an EICR?
No. Thermal imaging complements fixed wire testing by identifying heat-related risks that may not appear during standard inspection. It does not replace a full Electrical Installation Condition Report (EICR).
