Residential Mobility and Energy Performance Certificate (RMEPC) Index (LAD Geography)

Residential Mobility and Energy Performance Certificate (RMEPC) data are compiled through the linkage of Linked Consumer Registers (LCRs) and Domestic Energy Performance Certificates (EPCs) at a property level.

The data provide average and median changes in energy performance rating, potential energy performance rating, and total floor area associated with residential moves out of, into, and within each Local Authority District (LAD) in Great Britain (GB). These metrics are aggregated for the entire period from 2009 to 2026 and further segmented into three-year intervals within this timeframe. The data allow researchers to explore changes in residential mobility at the local scale, along with changes in housing energy performance and space. Both the average and median changes in energy performance rating, potential energy performance rating, and total floor area of the residences of movers are provided for adult individuals moving out of, moving into, and moving within each GB LAD. These datasets offer insights into overall changes in dwelling energy performance and floor area associated with residential migration throughout the entire time period, and provide more detailed information at three-year intervals. The data undergo annual updates.

Content

The RMEPC is delivered as a selection of six datasets, divided into three categories, which are labelled as 'move out' (mo), 'move into' (mi), and 'move within' (wi) for each LAD in GB. For each type of mover (e.g., move out), one dataset provides statistics for the entire time period between 2009 and 2026, while the other dataset provides statistics for every three-year segment within the same period. All changes are calculated as the value at the destination dwelling minus the value at the origin dwelling. Statistics for units with fewer than five movers are marked with an asterisk (*). Field level metadata are provided at the end of this profile document. These six datasets are aggregated results obtained from linking our Linked Consumer Registers (LCRs) and Domestic EPC data. A brief context of the linkage between LCR and EPC data is provided in the Technical Report on linking and validating, below.

(1) RMEPC move out

The RMEPC move out datasets provide average and median changes in energy performance rating, potential energy performance rating, and total floor area for the residences of individuals moving out of each LAD. Move-out records are those where the origin and destination LADs differ, and results are attributed to the origin LAD. Two RMEPC data products have been published. The first one, named 'rmepc_lad26_mo', aggregates data for the entire time period between 2009 and 2026, while the second one, 'rmepc_lad26_mo_threeyears', provides data for three-year intervals within the same time period.

(2) RMEPC move into

The RMEPC move into datasets provide average and median changes in energy performance rating, potential energy performance rating, and total floor area for the residences of individuals moving into each LAD in GB. Move-in records are those where the origin and destination LADs differ, and results are attributed to the destination LAD. Similar to the previously mentioned move-out datasets, there are two RMEPC move-in products. The first one, named 'rmepc_lad26_mi', aggregates data for the entire time period between 2009 and 2026, while the second one, named 'rmepc_lad26_mi_threeyears', provides data for three-year intervals within the same time frame.

(3) RMEPC move within

The RMEPC move within datasets provide average and median changes in energy performance rating, potential energy performance rating, and total floor area for the residences of individuals moving within LADs in GB. Move-within records are those where the origin and destination are in the same LAD. Two RMEPC move-within products are available. The first, labelled 'rmepc_lad26_wi', provides data for the entire time period spanning from 2009 to 2026. The second, named 'rmepc_lad26_wi_threeyears', provides data at three-year intervals within the same timeframe.

Quality, Representation and Bias

The underpinning data comprise linked LCR and EPC records, which establish links between Energy Performance Certificates (EPCs) and the origin and destination addresses of individual movers within the LCR migration model. RMEPC therefore includes only residential moves for which suitable EPC information can be linked to both the origin and destination properties. EPC availability and successful linkage may vary across geography and time, and the resulting RMEPC estimates may therefore not represent all residential moves recorded in the LCRs. For further details on the source and reliability of the linked LCR and EPC data, please refer to the Technical Report on linking and validating, below.
