Introduction to HEED

HEED provides a unique record of energy efficiency installations that have been implemented in the domestic building stock. This information is made available to organisations in order to help them plan, deliver and monitor progress on programmes to improve energy efficiency and alleviate fuel poverty.

HEED reports on aggregated data and no address level records are available. Outputs represent a record of activity and surveys that have taken place in Great Britain. As such, this data can’t necessarily be regarded as representative of the housing stock as a whole. As an example of this, HEED contains data from major installation programmes, such as CERT, CESP and EAP and therefore, it is biased toward the measures installed via those schemes, such as insulated cavity walls and lofts.

Local authorities in Scotland also have access to Home Analytics data. Home Analytics data contains elements of HEED, but is designed to provide a more comprehensive profile of the housing stock, taking in to account every address and systematically accounting for skews and biases in the underlying datasets. Home Analytics data is available down to the address level for local authority users in their own area.

What is HEED used for?

HEED data can be used to plan, deliver and monitor programmes to improve energy efficiency and alleviate fuel poverty.

What sort of data is available in HEED?

  • Property characteristics (property age, property type, property tenure, glazing type, external wall type).
  • Heating systems (main heating fuel, main heating system, heating controls).
  • Insulation installed (cavity wall insulation, loft insulation, hot water tank insulation, draft proofing measures).
  • Microgeneration technologies installed (heat pumps, solar PV, solar thermal).

Who can access HEED datasets?

HEED data can be accessed by individuals from any of the following organisations engaged in activities related to the energy efficiency of the UK housing stock:

  • Central and Local Government. 
  • Organisations contracted by any of the above to carry out domestic energy efficiency related projects (provided that an individual from the contracting organisation requests the account on behalf of the commercial organisation).
  • Universities, community groups and non-profit organisations.

Access to HEED means access via the Local Homes Portal to information on energy efficiency measures aggregated at the parliamentary constituency. Bespoke HEED reports with data aggregated at other geographical levels can be offered by the Local Homes Portal team, depending on your access level.

Because of the restrictions outlined in the agreements for obtaining the data, HEED access is not available to:

  • Individuals from commercial organisations.
  • Individuals from organisations intending to use HEED data for anything other than activities related to the assessment and improvement of the energy efficiency of the UK housing stock.

How do I get HEED access?

HEED is accessed securely through the Local Homes Portal. The Local Home Portal represents a centralized data hub for Home Analytics, HEED and EPC data that is designed to be accessed by a variety of users (e.g., householders, local authority users, supply chain users, etc.). In order to access HEED data, users need to login to the portal.

Prospective users of HEED are required to complete the application form, sign it and then return a scanned copy via email to Once the completed form has been received, the account setup process will be initiated. Your login details will be emailed to you when your account has been setup.
