£200 a year saving for insulated homes, says new assessment

20 April 2022

An assessment has found that boosting the energy efficiency of six million homes between 2009 to 2019 will save them nearly £200 per year from April 2022.

The Energy and Climate Intelligence Unit (ECIU) assessment found six million homes had been upgraded to energy performance certificate band C from 2009 to 2019 with measures such as loft and cavity wall insulation.

Upgrading a home from band D to band C reduces gas demand by 20% per home on average. This creates a saving worth £194 per year from April 2022 – and this could increase if energy bills climb further alongside rising wholesale gas prices.

Overall, an estimated £1.15 billion will be saved this year, from energy efficiency measures installed over the past decade.

Insulation rates have dropped since the government has cut back on green schemes such as the energy company obligation (ECO) since the coalition government in 2013.

“Insulation scheme like ECO work. They cut the energy being wasted from leaky roofs and walls, cut the amount of gas we need to keep warm and so bring down bills, and they do all that permanently.
