He noted that by taking on this challenge, homes can reduce their carbon emissions and "contribute to the UK’s legally binding commitment to reduce CO2 emissions by 80 per cent by 2050".
A new £3 million project by The Energy Technologies Institute could help developers achieve this, as it works to design a supply chain solution to improve the energy efficiency of UK homes.
Mr Miller added that homeowners and utility companies also have a responsibility to contribute to energy efficiency.
Now that First Utility has reached a threshold removing its exemption from rules that require energy suppliers to contribute to energy efficiency in homes, the firm has argued that competition is increased and it has a barrier for future growth.
However, Mr Miller said: "It’s only right and proper that gas and electricity suppliers contribute towards the carbon emissions reductions target."
