Heat Loss Survey | Infrared Thermographic Heat Loss Surveys London

We frequently conduct heat loss surveys for both private and public sector clients who find that their heating costs have soared or who have a particular concern with a room, extension or the whole property. The types of enquiries we receive vary from clients wishing to locate the source(s) of a draft, to establishing where their property is losing heat energy, to finding the causes of mold or fungus, damp walls, and bowing floors.

Our qualified thermal imaging specialists conduct surveys on homes or property, producing a report which clearly identifies individual areas where heat may be being lost or energy wastaed. We find, more often than not, that the problems are not what the client had thought they would be.

Here are some of the typical problems we are regularly called in to inspect for:

Missing or discontinuous insulation.
Thermal bridging.
Air leakage.
Air infiltration (drafts).
Defective seals in doors or windows
Water ingress / leaks.
De-lamination of rendering.
Locating electrical cables, pipes, joists & beams.
Mapping faulty areas of underfloor heating.

About the Thermal Heat Loss Survey

The Thermal Images above were taken during a Building Response Thermal Imaging Survey on a property in the South East of England. These Thermal Images, along with subsequent analytical findings by the head of our Thermal Imaging Diagnostics Department, James de Miguel, were presented in a professional report to the client, and subsequently the focus of a Daily Telegraph newspaper article.

Heat Loss Survey Examples

We use a range of additional test and inspection equipment including blower door fans, for creating negative pressure in buildings for the purpose of locating the source of drafts, borescopes and flexible camera units. Using a range of inspection methods allows us to provide accurate and detailed information and ensure that cost is minimised when conducting repairs or alterations.


Air can be seen blowing in under the eves of this roof and moving the insulation away from the edge of the property allowing drafts to be felt within the room. What you can see here is cold air movement creeping in through the ceiling and, over time, pushing the roll-out fiberglass insulation further and further back, dramatically reducing the thermal efficiency of the building.	Here, the insulation between the rafters has been blown away from the wall by the airflow up under the eves into the roof. This means that air circles under the ceiling plasterboard and drafts blow through the room. This occurs on many properties which require roof ventilation and is a common explanation for drafts.
