A house built between 1930 and 1949 has a better hot water efficiency score than one built in the last 10 years.
That’s according to the latest study by uSwitch, which revealed that the most boiler efficient period of homes being built was between 2003 and 2011, with a score of 8.36/10.
Using Energy Performance Certificates (EPCs) across the UK, the researchers compared the scores for efficiency in heating, hot water and boilers for properties constructed across the last century.
The study revealed that homes built since 2012 are the fifth-most efficient, with a combined score of 5.4/10. Despite being efficient with heating, they account for the least EPCs and have a hot water score of just 1.54/10.
Houses built before 1900 have a better boiler efficiency than those made between 1950 and 1982, as well as 1991 to 1995, the study claims.
The researchers recommend scheduling regular boiler check-ups and bleeding out radiators to ensure maximum efficiency and the lowest cost on energy bills.
