With the weather constantly on the up at the moment it seems like Britain may be able to enjoy a proper summer for once. However industry experts have warned that homes insulated under the Green Deal scheme could be facing dangerously high temperatures both over the coming months and future summer times. 

Prof Chris Goodier, of Loughborough University’s department of civil and building engineering, told the BBC that the risk of overheating had been overlooked in the “big rush to insulate and make homes airtight”. He cited homes in urban areas are most at risk from problems during summer heatwaves. 

"Overheating is like the little boy at the back of the class waving his hand," he said. "It is forgotten about because the other challenges are so big."

"If you are in the wrong type of house, facing the wrong way, in the wrong street and you don’t deal with heat in the right way, it is a problem. Particularly for the elderly. They are going to suffer. Suffering means they are going to die from overheating."

His team's report suggested that with the increased likelihood of summer heatwaves in the future, there could be a rise in heat-related deaths from 2,000 to 5,000 per year by 2080 if action was not taken. To combat this, the DECC are now issuing fresh guidance to Green Deal suppliers to help reduce this risk while continuing to install energy efficient measures.

In a statement they said: "If energy efficiency measures are installed appropriately, overheating should not be a common problem and there’s guidance available for those involved in the Green Deal."

“The DECC is working with experts and other government departments to understand the potential risk of overheating in retrofitted homes and ensure that the energy efficiency supply chain, including those working within the Green Deal, are aware and guidance is provided on homes which are most likely to be vulnerable and what steps could be taken to minimise any risk of overheating."
