The Labour Party has proposed a £3.2 billion-a-year plan to insulate four million homes, saving a combined £1bn from heating bills.

The cash, which will be made available to local councils, would bring houses up to Energy Performance Certificate (EPC) “C” by the end of a parliamentary term.

All social housing and low-income homeowners would receive the insulation for free under Labour’s plans.

The party said it would also tighten regulation of privately-rented homes, blocking poorly-insulated homes from being rented out.

‘Broken energy system’

Rebecca Long-Bailey, Labour’s Shadow Business Secretary, said: “Our ambitious insulation plan will see the next Labour government take real action against fuel poverty, making homes cheaper to heat, improving people’s health by improving our housing, creating new jobs and reducing carbon emissions.

“This is part of our plan to fix our broken energy system by capping energy bills and radically reform our broken energy market.

“By creating publicly-owned, locally-accountable energy companies and cooperatives to rival existing private energy suppliers this will make a real difference to people’s lives.”
