Thermal imaging (thermography) is a powerful, non-invasive diagnostic tool that allows our engineers to identify potential electrical faults and hotspots before they become serious — or dangerous — problems.

Using high-resolution thermal imaging cameras, our engineers can detect anomalies that are invisible to the naked eye, such as overloaded circuits, loose connections, failing components, and insulation defects. Our thermal imaging services include:

• Full site thermal imaging surveys of distribution boards, switchgear, and electrical panels.
• Motor and mechanical equipment thermal surveys.
• Electrical connection and termination hotspot identification.
• Detailed written reports with photographic evidence and recommended actions.
• Compliance with BS EN 13187 and insurance requirements.
• Follow-up remedial works to address identified issues.

Thermal imaging surveys are an excellent preventative maintenance tool, helping to avoid costly unplanned downtime, equipment failures, and electrical fires. Many insurance policies now require or recommend regular thermal surveys for commercial and industrial premises. Contact us to arrange a survey.

Portable Appliance Testing (PAT) is an important part of any workplace electrical safety programme. GDL Electrical Contractors provide a thorough, professional PAT testing service for businesses of all sizes, from small offices to large industrial facilities.
