Equans’ two-year project started last month, putting in new insultation, windows, doors, draughtproofing and energy efficient boilers.
The programme aims to achieve a minimum EPC rating of C for all the properties.
It is funded by the Social Housing Decarbonisation Fund (SHDF). Equans says it has been responsible for nearly 20% of all successful applications across waves 1 and 2 of SHDF.
