Retrofitting must shoot up the agenda if we are to stop energy waste says a construction research body.
With the government’s Warm Homes Plan set for a full unveiling this spring, the Building Research Establishment (BRE) is calling for immediate action to support homeowners in retrofitting 12 million energy-inefficient homes across England.
New data from the government’s English Housing Survey (EHS) shows that, for the first time, more than 50% of homes meet at least Energy Performance Certificate (EPC) band C.
However, while social housing has made strides in energy efficiency, private sector homes—both rented and owner-occupied—lag behind, posing risks to health, finances and the UK’s Net Zero ambitions.
The Warm Homes Plan has already introduced local grants targeting fuel poverty and the future of the £1 billion ECO scheme remains a key concern as its current phase ends in 2026.
But according to BRE’s analysis, the challenge goes beyond low-income households. Wealthier homeowners also struggle with poor insulation and outdated heating, while private rental properties have the highest proportion of EPC F and G homes.
With the NHS spending over £500 million annually treating cold-related illnesses, BRE insists the government must prioritise retrofit advice and financing support.
