How green is YOUR home? Stats experts find smaller properties like flats are most energy efficient

Smaller, newer homes are greener than larger, older properties, according to a new study of domestic energy efficiency.

The Office for National Statistics (ONS) has ranked homes in England and Wales in seven bands akin the way they are ordered for council tax.

They are then given a score, with Band A rated the most energy efficient and Band G the least.

The analysis by the ONS found that flats and maisonettes, homes in blocks are the most energy efficient, and larger semi-detached and detached houses are the least efficient.

The age of homes was also a factor, with older homes less efficient than newer ones, due to advances in insulation and boiler technology.

The median or middle ratings in England and Wales were 66 and 64 respectively, equivalent to Band D on the scale.

In news that shows the scale of the Government’s plans to make homes greener, the ONS found that In both countries, almost eight in 10 dwellings used mains gas as a main fuel source for central heating. 

Boris Johnson has spoken of his desire to phase out domestic gas by 2035.

The report noted: ‘Overall, flats and maisonettes were the most energy efficient property type in both England and Wales, with a median energy efficiency score of 72, which is equivalent to band C. 

‘Detached dwellings scored the lowest in Wales (62), whilst in England, detached and semi-detached (63) were joint lowest. These scores are equivalent to band D. 

‘This may be because of external wall exposure being higher in detached properties, compared with flats and maisonettes that are more likely to be grouped in blocks. 

‘Whilst there is a large difference in energy efficiency between flats and houses, there was only a small difference between the different types of houses, particularly in Wales.’
