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.

11 August 2023 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 revisions are summarised here:

Error 1: Local authority consumption estimates

• Extent of the error: Table LA13 and LA14 revised to correct for a processing error that was identified after accessible versions of the tables were published on 10 June 2022. The update did not include the ‘Unknown’ category which meant columns were misplaced. Table LA7 (2019 only) has also been updated to include data for counties, these rows previously appeared as [no data].
• Years affected: 2017-2019
• Countries affected: England and Wales
• Data tables affected:
  • Local authority table, England and Wales, 2019 (Tables LA7, LA13 and LA14)
  • Local authority table, England and Wales, 2018 (Tables LA13 and LA14)
  • Local authority table, England and Wales, 2017 (Tables LA13 and LA14)

Error 2: Some properties incorrectly excluded from the Scotland multiple attributes tables

• Extent of the error: These corrections primarily affect the number in sample column for all years as some properties were incorrectly excluded from the consumption estimates. There have also been revisions to the mean, median, upper and lower quartiles. Using 2019 as an example, around 80% of the updated mean and median values are within 300 kWh of what was previously published.
• Years affected: 2017-2019
• Countries affected: Scotland
• Data tables affected: Multiple attributes tables: Scotland, 2019 (all tables)

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 "https://www.gov.uk/government/statistical-data-sets/national-energy-efficiency-data-framework-need-data-explorer" class="govuk-link"><abbr title="National Energy Efficiency Data-Frame
