Summary of analysis using the National Energy Efficiency Data-Framework using consumption data from 2005 to 2019.
Documents
Details
The National Energy Efficiency Data-Framework (NEED) was set up to provide a better understanding of energy use and energy efficiency in domestic and non-domestic buildings in Great Britain. The data framework matches data about a property together - including energy consumption and energy efficiency measures installed - at household level.
4 August 2021 Error notice: revisions to the June 2021 Domestic NEED annual report
We identified 2 processing errors in this edition of the Domestic NEED Annual report and corrected them. The changes are small and do not affect the overall findings of the report, only the domestic energy consumption estimates. The impact of energy efficiency measures analysis remains unchanged. The revisions are summarised here:
Error 1: Some properties incorrectly excluded from the 2019 gas consumption estimates
- Extent of the error: The properties that were incorrectly excluded made up around 1% of all properties that should have been included
- Years affected: 2019
- Countries affected: England and Wales, Scotland
-
Data table and documents affected:
- the 2019 gas estimates in all Consumption tables
- the 2019 gas estimates in the NEED data explorer
- Domestic NEED report (Tables 2.1 and 2.2, Figures 2.2 and 2.3)
- Annex C: Comparisons with other data sources (Table 2 and all Figures)
- Annex D: Methodology note (Table 2.1)
Error 2: Processing of the EPC data
- Extent of the error: For around 6% of the properties used in the consumption estimates, the EPC rating used was not based on the most recent EPC assessment
- Years affected: 2017-2019
- Countries affected: England and Wales
-
Data tables affected: the gas and electricity consumption breakdowns by EPC rating in the following tables:
- Headline consumption tables (Tables 27-28)
- Additional consumption tables (Tables 27-28)
August 2021: Survey on the future of Domestic NEED closed
This survey (published June 2021) sought user feedback to inform BEIS’ development of Domestic NEED to better meet user requirements. It is now closed: thank you to those who responded.
We are reviewing responses and will provide an update in due course. The responses will also inform BEIS’ decision on whether or not to pause the 2022 NEED publication to enable development work to take place.
