Answered by Martin McCluskey
The number of unique households in Wales receiving measures under each Energy Company Obligation (ECO) phase between January 2013 and September 2025 is shown in the table below. Each property is counted when receiving an ECO measure for the first time under each phase. The total of 140,439 homes is lower than the sum of the phases as it shows the unique number of households receiving measures across the scheme.
These data have been derived from the Household Energy Efficiency statistics publication where further details on the measures delivered can be found.
