The aim is to improve the homes and reduce the fuel bills of almost 2,000 tenants of Solihull Council.
The project includes £25m of energy company obligation (ECO) funding and £2m of community energy saving programme (CESP) funding. The ECO project will insulate 35 Solihull Community Housing high-rise blocks and install bio-mass district heating units in 26 buildings.
All work is expected to be completed by 31 March 2015, with each individual high-rise taking just over three months to finish.
Phase one of the work has already begun on 10 of the borough’s high-rises, with the rest of the buildings following in succession.
Steve Gapik, from British Gas, said: “This will make a real difference for Solihull’s residents. Although energy costs may be rising, through this funding we are helping people to live in a comfortable, warm environment whilst keeping their energy bills down.
"The bio-mass installation in the 26 high-rises means that people living there will now have the ability to closely control their heating and hence manage their energy budgets.
“Solihull’s residents can expect to see a real improvement over the coming months as the partnership invests on a big scale to tackle fuel poverty and a wide range of energy problems.”
