This dataset displays the estimated costs to implement the energy efficiency measures to reach the annual heat demand displayed in the annual heat demand dataset. This data is available for all local authorities in England and Wales. It includes for each local authority: column 1 - "Local Authority (2019)" - The local authority (2019) - based on the classification from the Office of National Statistics. columns 2-17 - The average costs in UK pounds (GBP) to implement energy efficiency measures to reach the annual heat demand shown in the "Annual_heat_demand_LSOA.csv" file for 16 dwelling categories: column 2 - "Average energy efficiency improvements costs of detached gas boiler (GBP)" column 3 - "Average energy efficiency improvements costs of detached oil boiler (GBP)" column 4 - "Average energy efficiency improvements costs of detached resistance heating (GBP)" column 5 - "Average energy efficiency improvements costs of detached biomass boiler (GBP)" column 6 - "Average energy efficiency improvements costs of flat gas boiler (GBP)" column 7 - "Average energy efficiency improvements costs of flat oil boiler (GBP)" column 8 - "Average energy efficiency improvements costs of flat resistance heating (GBP)" column 9 - "Average energy efficiency improvements costs of flat biomass boiler (GBP)" column 10 - "Average energy efficiency improvements costs of semi-detached gas boiler (GBP)" column 11 - "Average energy efficiency improvements costs of semi-detached oil boiler (GBP)" column 12 - "Average energy efficiency improvements costs of semi-detached resistance heating (GBP)" column 13 - "Average energy efficiency improvements costs of semi-detached biomass boiler (GBP)" column 14 - "Average energy efficiency improvements costs of terraced gas boiler (GBP)" column 15 - "Average energy efficiency improvements costs of terraced oil boiler (GBP)" column 16 - "Average energy efficiency improvements costs of terraced resistance heating (GBP)" column 17 - "Average energy efficiency improvements costs of terraced biomass boiler (GBP)" columns 18-33 - The number of dwellings in each of the 16 dwelling categories in 2018. column 18 - "Number of detached gas boiler in 2018" column 19 - "Number of detached resistance heating in 2018" column 20 - "Number of detached oil boiler in 2018" column 21 - "Number of detached biomass boiler in 2018" column 22 - "Number of semi-detached gas boiler in 2018" column 23 - "Number of semi-detached resistance heating in 2018" column 24 - "Number of semi-detached oil boiler in 2018" column 25 - "Number of semi-detached biomass boiler in 2018" column 26 - "Number of terraced gas boiler in 2018" column 27 - "Number of terraced resistance heating in 2018" column 28 - "Number of terraced oil boiler in 2018" column 29 - "Number of terraced biomass boiler in 2018" column 30 - "Number of flat gas boiler in 2018" column 31 - "Number of flat resistance heating in 2018" column 32 - "Number of flat oil boiler in 2018" column 33 - "Number of flat biomass boiler in 2018" column 34 - "Total energy efficiency improvements costs (GBP)" - Total costs of implementing all the energy efficiency measures.
