The modernisation could save lower-income households on average around £200-a-year on their energy bills, according to the Business Department.
London minister Paul Scully, said: “The funding will offer crucial support to lower-income households across the capital, making homes warmer, greener and cheaper to heat, not only cutting emissions but also energy bills.”
He added: “With heating for homes and buildings making up almost a third of all carbon emissions, improving the energy efficiency of our homes will be a key part of ensuring we eliminate our country’s contribution to climate change by 2050.”
The investment is part of more than £400 million awarded to over 200 councils across England and comes from the Government’s Local Authority Delivery scheme and the Home Upgrade Grant.
It aims to improve the energy efficiency of some of the least “green” homes, rated between D and G on their Energy Performance Certificates.
Wandsworth Council Leader Ravi Govindia stressed the upgrades would mean “cheaper energy bills” for households who could “play their part in the nation’s efforts to curb carbon emissions and deliver a greener and lower carbon future”.
Cllr Cameron Geddes, Barking and Dagenham’s Cabinet member for regeneration and economic development, added: “This funding will enable us to support 320 local homeowners on lower incomes, by providing them with energy efficient measures that will keep their homes warmer and ultimately save them money on their energy bills.”
The scheme is part of the Government’s £6.6 billion strategy to cut carbon emissions from homes as it seeks to make Britain net zero by 2050.
Heat in homes accounts for 21 per cent of all UK carbon emissions.
