Locations slammed for failing to meet energy efficiency targets

New analysis claims that the North East of England has made “no progress on greening the highest-emissions homes in 13 years.”

Meanwhile, the same analysis claims the South West has made the most progress in tackling the highest domestic emissions.

The Powering Net Zero Group (PNZ) says domestic carbon emissions from the least green homes in the North East, the North West, and Yorkshire and the Humber have remained stubbornly high since 2010. 

Homes account for almost a quarter of the UK’s total carbon emissions, and - according to PNZ - represent the biggest barrier to reaching net zero by 2050 without retrofit intervention.

Nearly 700,000 homes in England and Wales fall into the highest percentiles of domestic emissions, which are broadly equivalent to EPC ratings of F or G, the two lowest bands for energy efficiency. 

These homes emit over 100kg of carbon dioxide per square metre, annually, compared with the average home’s 40kg.

But the PNZ Group’s analysis reveals a North / South divide developing when it comes to tackling high-emissions dwellings. 

In the North East, the North West, and Yorkshire and the Humber, 3.1 per cent of homes in 2023 were recorded as ‘high-emissions homes’. 

This number stands barely unchanged from 3.4 per cent of northern homes in 2010, showing a glacial pace of decarbonising the most carbon intensive houses.

Of all English and Welsh regions, the North East has the longest road to decarbonising its high-emissions homes, with no change at all in the proportion of these environmentally taxing homes in the last 13 years - from 2.37 per cent of homes in 2010 to 2.37 per cent in 2023. 

The PNZ Group’s data reveals the North West and Yorkshire as having made the second- and third-slowest progress on carbon intensive homes, with a less than 0.5 per cent reduction in high-emissions homes since 2010. 

Overall, nearly 220,000 high-emissions homes remain in the North of England, which will need to be reduced to 0 to meet the UK’s net zero target.

In contrast to England’s North, the number of high-emissions homes in the South of England and in Wales is dropping steadily - PNZ says this is the result of concerted interventions to make homes greener, through heat pumps, double glazing, or solar panel installation. 

Despite having the highest proportion of emissions-intensive homes of all regions in 2010 at 6.5 per cent, the South West has made the most progress on its domestic emissions, with that proportion dropping to 3.7 per cent in 2023. 

Eden in the North West is the local authority with the most energy intensive homes in England and Wales – a staggering 16 per cent of homes emit over 100kg of carbon dioxide per square metre in 2023 compared to the national average of 2.8 per cent.

This is an increase of the number of high-emissions homes on 2010, when 11 per cent of homes were considered energy-intensive. 

In fact, over a tenth local authorities in England and Wales are seeing the number of high-emissions homes climb since 2010. Of the 36 local authorities where high-emissions homes are increasing in number, 25 are located in the North of England.

PNZ co-founder Simon Turek says: “Our data analysis tells the story of a huge regional divide in improving the UK’s housing stock, where Northern England has been left behind. 

“Making UK homes - particularly the most carbon intensive - more energy efficient is a huge hurdle to reaching net zero emissions by 2050. Government retrofitting schemes cover some ground, but the scale of funding needed to green our homes means we need private sector investment too.”
