Smart Energy Research Lab: Energy use in GB domestic buildings 2022 and 2023

This report – Volume 2 of the SERL Statistical Reports Series – describes domestic gas and electricity energy use in Great Britain in 2022 and 2023 based on data from the Smart Energy Research Lab (SERL) Observatory, which consists of smart meter and contextual data from approximately 13,000 homes that are broadly representative of the GB domestic building stock along a range of geographic, building and socio-demographic characteristics. The report provides an update to the statistics provided in Volume 1 of the SERL Statistical Report Series (Few et al., 2022), which covered 2021 data, and analyses residential energy use in GB in 2022 and 2023 (over the whole year, in each month and half-hourly over the course of the day). Statistics are presented for groups of homes with specific occupant characteristics (number of occupants, tenure), property characteristics (age, size, form, and Energy Performance Certificate (EPC)), heating systems, photovoltaics and electric vehicles, and by weather, region and IMD quintile. Unless otherwise noted, the findings in the report relate to homes in the SERL Observatory that use gas as their main heating source and do not have photovoltaic (PV) electricity generation. The report also shows how metered residential energy use in GB varies over time from 2021 to 2023.
