Key Findings from Watt a Save 2026
The 2026 data shows that new build homes are 23% cheaper to run than older homes, thanks to their superior energy efficiency. This translates into real savings for homeowners:
- £450 annual savings: People living in new build homes save on average around £450 a year on their overall energy bills compared with those in older properties.
- Lower running costs: On average, new build homeowners spend around £1,530 a year on energy compared with £1,980 on older homes.
- Even greater savings vs inefficient homes: The average new build is £630 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:
- 50% less carbon: Virtually all new builds have an A or B EPC rating, meaning the average home emits around 2,160kg of carbon per year. Most older homes have an EPC D rating which means they produce 3,240kg of carbon annually – 50% more.
- Up to 74% reduction: Older homes with an F or G EPC emit 74% more carbon than most new build homes, producing 3,780kg every year compared to just 2,160kg for new builds.
