This data profile describes the Residential Mobility and Energy Performance Certificate (RMEPC) datasets held by the Consumer Data Research Centre (CDRC), which are created through original CDRC research. The index data are compiled through an analysis involving the linkage of CDRC Secure Data Linked Consumer Registers (LCRs), and Department for Levelling Up, Housing and Communities (DLUHC) Domestic Energy Performance Certificates (EPCs), at property level. The data provide average and median change of energy performance ratings, potential energy performance ratings and total floor area of residences involved in moves in and out of each Lower Level Super Output Area (LSOA) level in Great Britain (GB) between 2009 and 2023

These research-ready datasets allow researchers to explore changes in residential mobility at the local scale, along with changes in housing energy and space. Both the average and median changes in energy performance rating, potential energy performance rating, and total floor area of residences involved in moves are provided for adult individuals moving out of, moving into (which includes both moving into and moving within), each UK LSOA.

Content
The RMEPC (LSOA) is divided into two datasets: one for “move-outs” (mo) and another for “move-ins” (mi) for each LSOA in GB. Field level metadata are provided at the end of this profile document. These two datasets are aggregates resulting from linking CDRC LCR and EPC data.
(1) RMEPC move out
The RMEPC move out (rmepc_lsoa11_mo) data provide average and median changes of energy performance rating, potential energy performance rating, and total floor area for the residences of individuals moving out of each home LSOA.
(2) RMEPC move in
The RMECP move into (rmepc_lsoa11_mi) data provide average and median changes of energy performance rating, potential energy performance rating, and total floor area for the residences of individuals moving into and within each LSOA in GB.

Quality, Representation and Bias
The underpinning data are from the CDRC LCR_EPC dataset, which establishes links between EPCs and the origin and destination addresses of individual movers within the LCR migration model. Only around 59% of residential properties across Great Britain have EPC records for the period between 2009 and 2023. This partial record coverage means that, for nearly half of the movers within this time period, EPC information cannot be linked to the LCR migration model, due to the EPC data being unavailable for either their previous or their current addresses. Furthermore, it is important to highlight that the representation of Scottish EPCs in the dataset is lower when compared to England and Wales. Consequently, movers with EPCs in the CDRC LCR_EPC data in Scotland appear to be reduced, compared to England and Wales.
