Thermographic Surveys & Thermal Imaging

A thermographic survey uses infrared thermal imaging cameras to detect temperature differences across building surfaces. These temperature variations reveal issues like heat loss, thermal bridging, air leakage, moisture ingress, and insulation defects that are invisible to the naked eye. The camera produces color-coded thermal images showing hot and cold areas, which our qualified thermographers analyze to identify problems and recommend solutions.

For building envelope surveys, winter months (October to March) provide optimal conditions when there’s a significant temperature difference between inside and outside (ideally 10°C+). Surveys are typically conducted in the evening or early morning when external temperatures are lowest. However, electrical thermography, solar panel inspection, and moisture detection can be performed year-round. For new construction, surveys should occur before final finishes are applied but after heating systems are operational.

Yes, thermal imaging is required for BREEAM Ene 01 (Energy Efficiency) credits. Thermographic surveys identify thermal bridging and building envelope defects that could compromise energy performance. The survey must be conducted by a qualified thermographer and documented with thermal images and analysis. We provide BREEAM-compliant thermography reports suitable for assessor review and help contractors achieve target ratings efficiently.

Our comprehensive reports include annotated thermal images showing areas of concern, corresponding visible light photographs for context, temperature measurements, detailed analysis of findings, severity ratings for identified issues, and practical recommendations for remedial action. Commercial and BREEAM reports include technical specifications, compliance statements, and documentation suitable for building control or assessor submission. Reports are typically delivered within 5-7 working days of the survey.

Yes, thermal imaging is excellent for detecting moisture-related issues. Water and damp areas appear cooler than surrounding dry materials due to evaporative cooling, creating visible temperature differences on thermal images. We can identify hidden leaks in walls, roofs, and floors, trace leak paths, detect rising damp, locate areas of condensation risk, and verify drying after water damage. However, thermal imaging shows temperature differences—we use moisture meters to confirm actual moisture content when necessary.

Survey duration depends on property size and complexity. A typical residential thermal survey takes 1-2 hours on site. Small commercial buildings require 2-4 hours, while larger commercial properties may need a full day or multiple visits. Electrical thermography surveys are usually completed within 2-3 hours. We work efficiently to minimize disruption while ensuring thorough coverage. Survey timing is critical—we schedule appointments for optimal thermal conditions, typically early morning or evening.

Yes, proper preparation ensures accurate results. For building envelope surveys: heat the property to normal living temperature (20-21°C) for at least 12 hours before the survey, remove furniture and obstructions from external walls where possible, ensure we can access all rooms including lofts and basements, and close windows and external doors. For electrical surveys, we need access to distribution boards and electrical equipment. We’ll provide a detailed preparation checklist when booking your survey to ensure optimal conditions.
