What is Thermal Imaging & Why is it Important?
Thermal imaging is a non-invasive diagnostic technique that uses infrared technology to detect hidden electrical faults in real time. Without needing a shutdown, our certified thermographers identify temperature anomalies that could indicate potential issues such as loose connections, overloaded circuits, or failing components.
Benefits of Thermal Imaging for Your Business:
- Prevent Costly Downtime – Detect and fix electrical faults before they disrupt operations.
- Improve Workplace Safety – Reduce fire hazards and electrical failures.
- Extend Equipment Life Span – Identify stressed components before they fail.
- Ensure Compliance – Meet UK safety regulations including NFPA 70B, BS 7671, and OSHA requirements.
- Lower Insurance Costs – Many insurers require thermal imaging inspections to mitigate risk.

Frequently Asked Questions
What is thermal imaging for electrical systems?
Thermal imaging is a non-contact, non-destructive method of detecting temperature variations in electrical components, helping identify potential issues before failures occur.
What electrical accessories are surveyed?
A survey inspects Distributin Panels, Distribution Boards, Contactors, Motors, Control Panels, Transformers & Isolators during normal operation.
What are the benefits of electrical thermal imaging surveys?
Electrical thermal imaging surveys are non-intrusive and will not affect normal business operation. The report compliments EICRs and has the potential to extend your equipments life and reduce the cost of breakdowns.
Why do I need thermal imaging for my electrical system?
It helps prevent costly downtime, enhances safety, and allows early detection of overheating, loose connections, overloaded circuits, and faulty components.
How does thermal imaging work?
A thermal camera detects infrared radiation (heat) emitted by electrical components and creates a visual heat map, allowing professionals to identify hotspots.
How frequent should surveys be carried out?
Usually every year, however, following your first survey our specialist will advise accordingly based on the age and condition of your installation.
Do Distribution Board covers need to be removed during the survey?
Preferably yes, we achieve more accurate results by having a direct line of sight with the accessories/ conductors under test.
Is thermal imaging safe?
Yes, it is a completely non-invasive and non-contact method, meaning there is no risk to equipment or personnel.
