Energy Follow-Up Survey

Modification Notice Original description: BEIS wishes to commission a project to provide detailed, high-quality current data and analysis on domestic energy consumption in England.

In order to effectively design policies to decarbonise domestic heat and contribute to reducing consumer energy bills, a detailed understanding of how households use energy, as opposed to what is predicted in models, is required.

A number of important evidence gaps exist that have not been covered in previous surveys or studies.

The research focusses on questions related to primary and secondary heating consumption, temperatures, occupancy patterns, over- and under-heating, understanding variations in energy consumption between similar dwellings, trade-offs made by fuel poor households with regards to energy consumption, electrical appliance use, total household energy consumption, comparisons of energy consumption with Energy Performance Certificates, lighting systems, the current prevalence of smart technologies, damp problems and ventilation.

Description of the modifications The variation adds the following to the original contract: Extension of monitoring to cover winter 2018/19.

Equipment now removed during April/May 2019 instead of February/March 2019 as in the current contract The inclusion of a Wave 1 online survey to increase the EFUS Wave 1 sample size.

This will obtain the necessary 350+ responses to meet the minimum requirement in the ITT The inclusion of a Wave 1a online survey to increase the Wave 1a sample size Description of the economic or technical reasons and the inconvenience or duplication of cost preventing a change of contractor: The work required for the variation requires the knowledge, skills and access to data that the original contractor holds (for whom we competitively tendered).

To compete the variation would have been impractical due to the highly specialised technical nature of the project, as well as being uneconomic given its relatively low value.
