The Home Builders Federation recently published their latest ‘Watt a Save’ report, highlighting the cost savings and energy efficiency benefits of new build homes:
On average, new build homeowners could save around £420 a year on energy bills compared with those living in older properties, with annual energy costs of about £1,574 versus £1,995*. This means new build homes are around 21% cheaper to run*, delivering consistent savings on energy bills.
The potential savings increase further when comparing the EPC ratings of new builds to the least efficient properties. Nearly all new-build homes achieve an A or B EPC rating, making the average new build 39% cheaper to run, at around £618 a year less than an older home with an F or G EPC rating*.
Modern construction standards mean better insulation, lower energy use and lower running costs – helping homeowners save money while reducing their environmental impact.
