Key Findings from Watt a Save 2026
The 2026 data shows that new build homes are 21% cheaper to run than older homes, thanks to their superior energy efficiency. This translates into real savings for homeowners:
- £420 annual savings: People living in new build homes save on average around £420 a year on their overall energy bills compared with those in older properties.
- Lower running costs: On average, new build homeowners spend around £1,574 a year on energy compared with £1,995 on older homes.
- Even greater savings vs inefficient homes: The average new build is £618 a year cheaper to run than an older home with an F or G EPC rating.
Environmental Impact
Beyond the financial benefits, new build homes are making a significant contribution to reducing carbon emissions:
- A third less carbon: 87% of new builds have an A or B EPC rating, and the average new build emits around 2,179kg of carbon a year. Most older homes have an EPC D rating and produce 3,266kg a year, 50% more than new builds.
- Up to 42% less carbon: New build homes emit 42% less carbon than older homes with an F or G EPC rating, producing just 2,179kg a year compared with 3,787kg.
