Contractors City Energy Network, Next Energy Solutions and Golden Globe Merchants will form a partnership with the council to leverage private funding of up to £45m each year from the Energy Company Obligation (ECO) programme.

The retrofitting initiative aims to significantly reduce fuel bills for thousands of families by making the homes more energy-efficient.

The scheme will enable the installation of new insulation, improved ventilation, more efficient heating systems, and solar panels in homes found in some of the city’s most deprived areas.

It’s expected that the majority of the homes that will be retrofitted will be privately owned homes, although it is also an opportunity to improve some of Birmingham’s social homes.

Cllr Jayne Francis, Cabinet Member for Housing and Homelessness, said: “In addition to reducing fuel costs by an estimated £1.2m per year for residents, this project will play a significant role in reducing the city’s carbon output.

“All three contractors bring substantial expertise and a proven track record in successfully delivering similar projects throughout the country.”
