Thermal Imaging & Commercial Buildings
Thermal Imaging Surveys for Commercial Buildings
Thermal imaging (thermographic) surveys are one of the most effective diagnostic tools for identifying heat loss in commercial buildings across London and the South East. Using advanced infrared technology, these surveys clearly highlight where energy is escaping, often revealing issues that building owners are completely unaware of.
Many of our clients are genuinely surprised by the number and scale of heat loss sources uncovered during a thermal imaging survey. Common problems include cold draughts caused by air leakage through cracks in the building envelope, as well as missing or poorly installed insulation within walls, floors, or roof spaces, sometimes entire sections are found to have been overlooked during installation.
How Do We Carry Out a Thermal Imaging Survey?
We aim to arrange a site visit at a time that is convenient for you. Thermal imaging surveys are typically carried out between November and April, as suitable weather conditions are essential for accurate results. In some cases, surveys may need to be rescheduled if conditions are unsuitable, such as during heavy rainfall or periods of high daytime and nighttime temperatures.
On arrival, our thermal engineer will discuss any known heat loss issues, draughts, or comfort concerns you have, as well as your objectives for the survey. Unlike many competitors, we always conduct both internal and external thermal surveys as standard, ensuring a comprehensive assessment of your building’s performance.
How Long Does a Thermal Imaging Survey Take?
The duration of a survey depends on the size of the building and how involved you wish to be. We strongly encourage building owners or site representatives to accompany our engineer during the inspection. This collaborative approach allows us to explain findings in real time and ensures you gain a clearer understanding of the issues identified.
- Small to medium buildings: 1–2 hours
- Large commercial buildings: 3–4 hours
Allow additional time if you have specific questions or multiple areas of concern.
When Will You Receive the Thermal Imaging Report?
Your comprehensive thermal imaging report is typically delivered within 1–2 working days in PDF format. The report includes:
- Thermal and visual images
- Clear interpretation of findings
- Identification of defects and potential causes
Many other providers take 1–2 weeks to deliver reports, so our fast turnaround ensures you can act quickly.
Why Choose Us for Your Thermal Imaging Survey?
Our engineers are trained to Level 3 thermographic certification, the highest level achievable in the industry. Combined with our use of large-format FLIR thermal imaging cameras, this ensures the highest possible accuracy and clarity when identifying defects.
Our Specification Includes:
- Level 3 thermographic certification
- Level 3 qualified thermographers
- Large-format FLIR cameras with 45-degree lenses
This combination gives you the best possible chance of accurately diagnosing and resolving thermal performance issues.
What Types of Buildings Benefit from Thermal Imaging Surveys?
Thermal imaging surveys are suitable for a wide range of building types, including:
- Commercial buildings
- Office blocks
- Schools and colleges
- Warehouses and storage facilities
- Military infrastructure
- Flats, houses, and residential tower blocks
- Housing stock (local authorities and property managers)
- Flat roofing systems
What Building Defects Can Thermal Imaging Identify?
Thermal imaging surveys can reveal hundreds of potential defects. Some of the most common issues we identify include:
- Poor construction detailing
- Missing or damaged insulation
- Thermal and cold bridging
- Air leakage and unintended openings
- Moisture penetration and water ingress
- Poor thermal comfort
- Damp and mould issues
