Thermal Imaging Surveys

Detect Hidden Building Issues with Thermal Imaging

Maintaining the health, efficiency, and safety of your building starts with understanding what’s happening beneath the surface. Thermal imaging surveys use advanced infrared technology to detect temperature variations, revealing hidden issues invisible to the naked eye. From energy loss and water leaks to structural defects, our surveys provide a comprehensive diagnostic solution for both commercial and residential properties.

With over 15 years of experience delivering premium building thermographic surveys across England and Wales, we provide detailed reports that satisfy the requirements of construction and insurance companies, facility managers, building control, and BREEAM assessors.

What is Thermal Imaging?

Thermal imaging, or thermography, captures infrared radiation emitted by objects. Unlike visible light, infrared radiation is invisible to the human eye, but thermal cameras can detect it and convert it into a detailed thermal image. Different colours represent temperature variations, making it easy to identify potential problems such as:

Excess heat loss – due to damaged or missing insulation
Moisture intrusion – from leaks or water ingress
Electrical faults – overheating components or faulty wiring
Structural defects – compromised walls, floors, or ceilings

Thermal Imaging Surveys for Commercial Buildings

Our commercial thermal imaging surveys provide valuable insights into your building’s thermal performance at minimal cost. Surveyors and facility managers rely on us for accurate detection of building defects. Infrared surveys can reveal:

Energy efficiency opportunities – identify where the largest cost-saving measures can be made
Damp or water ingress – including leaks in roofs, walls, ceilings, or roof lights
Thermal bridging – missing or ineffective insulation at windows, doors, and structural junctions
Air infiltration – cold drafts that reduce comfort for occupants
Air leakage paths – energy losses due to escaping warm air

Thermal Imaging Surveys for Homes

Our residential thermal imaging surveys provide homeowners with actionable insights to improve comfort and reduce energy bills. Common issues we detect include:

Heat loss and energy efficiency gaps
Damp walls, ceilings, or floors
Hidden water leaks in underfloor heating or pipework
Thermal bridging at doors, windows, and junctions
Missing or damaged insulation
Cold drafts or air leakage compromising comfort

BREEAM Thermal Imaging Surveys

Thermal imaging is a key component of BREEAM — the world’s leading environmental assessment and rating system for buildings. Both BREEAM New Construction and BREEAM Domestic Refurbishment recognize the importance of thermal imaging, awarding credits for surveys conducted by certified thermographers.

At APT Sound Testing, our Level 3 certified thermographers use high-resolution FLIR cameras to ensure insulation continuity and deliver precise results for every project.
