Our C-Change sustainable homes discount applies to new and existing energy efficient homes. Once your build is complete, you need to provide an energy standard certificate and architect/Building Control certificate for us to apply the discount. This is applied from the date we receive all the required documentation and is based on the energy rating or standard the property achieves.
