The UK's housing stock is older than similar nations, with over half the homes in England built before 1965 and almost 20% built before 1919. According to the ONS, the age of a property is the single biggest factor affecting its energy efficiency. Nearly half of low-income households in England still live in homes with an Energy Performance Certificate (EPC) rating of D or below, meaning they may use 27% more gas and 18% more electricity on average than EPC C-rated homes.

The UK has experienced years of low home insulation rates. In 2013, government cut support for insulation and rates fell by around 90%, with successive policies failing to resurrect the industry due to being ended early or not funded enough. [...]
Retrofitting a new home to meet energy efficiency standards - including replacing its gas boiler with a heat pump - could cost a household an average of £26,000, according to Climate Change Committee (CCC) data. That is over five times more than the £4,800 it would have cost to meet the standard when the property was first built. The Zero Carbon Homes Standard was supposed to be implemented from 2016 onwards but was scrapped in 2015 - this led to over a million homes being built to poor standards, which will ultimately cost the thousands of people who bought those homes millions of pounds.
One local authority pointed to local authorities' existing statutory duty to consider and preserve local heritage, making it essentially impossible for them locally to improve the energy efficiency of listed homes and buildings, or those in conservation areas. [...]
There are now around 10,000 conservation areas in England, covering an area the size of Luxembourg.
