The ‘You’ve Got the Power’ report found that the new homes being built in England and Wales were considerably more energy efficient than their predecessors.
According to Energy Performance Certificate data, more than eight out of 10 new builds have the top A or B rating for energy efficiency, compared with just 2.2% of existing properties.
The government data also showed that as a result, new homes were using on average 103kWh/m2 worth of energy, compared with an average of 294kWh/m2 for existing homes.
This means that new-build homeowners will spend on average £443.30 a year on energy, while owners of older homes will spend £1,072 a year.

“Today’s new homes are significantly more energy efficient than their predecessors, delivering huge benefits both for their owners and the environment,” said Stewart Baseley, executive chairman of the Home Builders Federation.
“Owners are saving hundreds of pounds a year in energy bills due to the modern design of their homes and the materials used to construct them.
“With energy bills expected to increase further, households will continue to reap the financial rewards in the future, allowing families to spend more of their money on the things they want, instead of simply keeping warm.
“With housebuilders’ ongoing investment in innovation, it is clear that the industry is committed to driving yet more savings for homeowners.”
