“iRed have proved themselves to be very flexible in fitting in with our policies and procedures, the engineers have been very efficient and I have been impressed with the final presentation of the results.”
“Just had a two day multispectral imaging training course which was really informative. The team at iRed are really professional and very welcoming. I will definitely be returning to them for more upskilling.”

THERMAL IMAGING TRAINING
Interested in becoming an accredited thermographer? iRed® is the UK’s largest thermal imaging training centre, accredited to national standards.
Classroom, blended, e-learning and on-site training options available.
Thermal imaging (also known as Infrared Thermography) uses heat-sensitive cameras to detect subtle differences in temperature. These cameras can detect temperature differences of less than 1ºC.
First designed for anti-aircraft defence in Britain, infrared cameras used to take over an hour to create a single image. Now, they’re practically instant. Whilst often seen used for search and rescue, thermal technology is capable of much more. For inspections, infrared cameras can quickly find and assess heat loss. This is used to inspect buildings, electrical equipment, machinery and assets.
Any object with a temperature above absolute zero (-273.15ºC) emits infrared radiation. The higher the temperature of the object, the greater the intensity of infrared radiation.
Infrared technology is designed to detect the intensity of radiation given off by an object. Once detected, a thermal camera creates an image of the object – based on the radiation it emits. This image is rendered using artificial colours, turning invisible radiation into a visible image.
Once captured, thermal images can be analysed to establish patterns and interruptions. For example, a loose connection in an electrical circuit or hidden defects in a building.
Technically yes, and unfortunately many people do.
The problem is infrared cameras cannot take accurate readings without adjustments. Factors such as reflected apparent temperature and emissivity must be changed in order to collect reliable information. When data is not collected properly (for example during the day), users often mistake functioning building elements as faults, leading to expensive and unnecessary remedial works.
As the preferred supplier for NHBC, we act as an expert witness on many of these reports – and more often than not we find that they’re inaccurate and unreliable.
iRed® has the largest team of accredited thermographers in the UK, all of whom are further approved by the UKTA to deliver certified BREEAM® surveys. Alongside this, we’re CHAS Accredited, Cyber Essentials Tier 1 Certified, CAA Approved and ISO 9001:2015 Certified.
Thermal cameras are not affected by light, and work just as well in daylight as they do in complete darkness.
The problem with working in daylight however isn’t to do with light, but with ambient temperature. Thermal cameras are heat-sensitive, so to accurately capture heat loss (or gain) there needs to be a difference in temperature. During the day, a building is externally heated by the sun, which in turn warms up the building fabric. This means that any heat escaping from the building is hidden, and is unlikely to be detected.
Specific surveys, such as electrical surveys and solar farm surveys, do not have the same requirements.
