Home Heat Loss

  • In a typical British home, around one-third of the heat produced by a central heating system is rapidly lost through the roof, ceiling and walls.
  • This means that for a poorly insulated property up to £1 out of every £3 spent on heating is being wasted.

For advice and information on how best to insulate your property and reduce heat losses please visit the Energy Saving Trust website (external link).

Heat loss will typically occur:

  • through the roof
  • through the walls
  • through doors/windows and floors

How much heat is YOUR home losing?

View of the Thermal Mapping website

Haringey Council purchased the data covering the London Borough of Haringey from a survey carried out by Horton Levi during the winter of 2000  and this can be viewed by following the link to the Haringey Thermal Image website (external link).

Furthermore we are delighted to be able to inform you that the data captured on the night of 16 March 2007 by aerial information specialists BlueSky International Ltd. has now been processed and can be viewed by clicking on the link to the Haringey Thermal Image website (external link).

Funding provided by the Neighbourhood Renewal Fund for a project to reduce the levels of fuel poverty in the borough enabled the purchase and subsequent processing of both sets of data. Further information is available on the project by clicking on the links on the left.

Haringey Council is absolutely delighted to be the first English council to publish the results of an aerial thermal survey on its website. The sole aim of the project is to assist residents with properly insulating their properties. Therefore please ensure that you read the associated pages on energy efficiency and the grant assistance that may be available to you.

Please remember that the aerial thermographic survey is a snapshot taken at one moment in time of how much heat your property was losing when the aeroplane flew over. The information provided is useful, but not the definitive guide to how energy efficient a property is as the amount of heat a building loses can be influenced by many factors.

Please read the page on thermal imaging for more information
