4 reasons for all seasons

Damp Detection

During the course of a heat loss survey we may find evidence of damp or even possible leaks that are contributing towards overall heat loss.

Insulation Issues

A heat loss survey will highlight any areas of a property where the insulation has deteriorated and is not performing the task it is meant to.

Structural Problems

If a property has structural issues then it is certainly suffering heat loss as a result of this. Our heat loss survey can find structural issues in areas you couldn't see otherwise.

Investment Assurance

When buying a property you want to know that you are getting your money's worth. With our heat loss survey you can have a comprehensive assessment of your potential property.

A heat loss survey is an eye-opener into the overall health of your property and will let you know just how energy efficient the building itself actually is. This thorough survey will analyse all aspects of the building to ascertain its strengths and weaknesses when it comes to the conservation of heat and where you can resolve and improve any weak points. Protect your home or business with a comprehensive heat loss survey from Direct Thermography.

The way that heat loss is viewed in reference to a building is to measure the level of heat that is allowed to transfer through the fabric of a building from within to the outside. There are four ways of classifying heat loss and the way in which it is able to occur and these are; convection, conduction, radiation and evaporation. Any one of these four pathways for heat loss to occur can be the reason why your property is not as energy efficient as it could be, or it could be a combination of these.

Convection heat loss in reference to a building would refer to heat loss that occurs from heat transferring from the building into the ground and dispersing. Conduction heat loss is affected by seasonal changes to weather and temperature, such as heat loss will occur more severely in winter when it is colder. Radiation heat loss refers to heat loss from the building into the open air. Finally, evaporation heat loss is when heat will transfer into contact water on the property after it has rained and the heat transfer causes the water to evaporate and dissipate the heat.

If you were considering a heat loss survey for a domestic property there are some useful facts that will highlight why a heat loss survey can help you to save money and improve the overall quality of your property. A terraced house is far more likely to suffer heat loss from convection and radiation heat loss as it is more likely that heat will escape through the roof and into the ground. In comparison, if a heat loss survey were to be conducted on a flat, it would show that heat primarily escapes from the outside wall of the flat. For a detached house, it is more likely to be exposed to greater levels of heat loss and combinations of more than one form of heat loss.

Studies have shown that the statistics of heat loss from domestic properties have found the levels most common for each form of heat loss and certain areas of properties where it occurs the worst. Heat loss through a building’s roof can account for 25% of the property’s overall heat loss. Up to 35% of overall heat loss can occur through outside walls, this statistic is particularly relevant for detached homeowners. It has been found that 25% is accounted for through windows and doors but by having double glazing, when these windows and doors are closed they are still able to retain heat well. Finally, a further 15% is lost to it spreading from the building into the ground.

Thankfully, all of these issues surrounding the potential loss of heat from your property can be addressed and altered by having it brought to light with a heat loss survey from Direct Thermography.


A thermal imaging, or FLIR, camera works by detecting the infrared radiation of a given object, person or animal based on the surface temperature. Due to this, and the fact that this practice is both non-contact and non-invasive it means that there are many applications and uses for this excellent technology.   

Thermal imaging cameras have a wide range of applications and uses across an array of different industries and professions. The fact that a thermal imaging camera is able to produce results without any contact or invasion means that you can get easy and accurate answers.

As well as this, it also allows for whatever it is that is being assessed to be in operation during the survey which can be far more insightful than other methods. The industries that we most frequently conduct surveys for are; aerospace, automotive, buildings, chemical, electrical, mechanical, medical, pest control and veterinary.

Within these industries are multiple different applications for the effective use of thermal imaging cameras and their fantastic infrared detection technology. 

Yes, a thermal imaging camera can indeed be used during the daytime and daylight hours. The reason for this is because a FLIR camera contains a special lens. What this lens does is that it focuses the heat given off of whatever it is that is being assessed onto a detector that is sensitive to heat. Therefore, a thermal imaging camera is not affected by light and produces equally brilliant results during the day as it would at night too. 

Once you are aware that you require a thermal imaging survey then it is time to either pick up the phone to give us a call or fill out the contact for that can be found on every page of this website. We will then arrange a time that is convenient for you to be able to come and provide a free quote for the cost of the service you require. If you have already received a quote from another company, inform us of this for us to beat their price. Then it is time to get down to business, our thermal imaging survey specialists will conduct a thorough survey of whatever you require. Once we are satisfied that we have a comprehensive assessment of the given subject of the survey then we will process the data of this. We provide a report of the survey which outlines the findings of it and explains it in a way that can e understood and that will include the images from the survey too. 

A thermal imaging survey will vary in cost, depending on multiple factors. Our service is entirely mobile as we can transport our thermal imaging cameras to wherever they are needed. If you are very far away from on of our offices then this may factor into the cost of your survey. Typically, a thermal imaging survey will be based around a day rate. This is subject to change by factors such as; the selected service, the necessary equipment to complete the survey, the time taken to complete the survey or other factors that are also subject to change.
