A new online map showing all UK postcodes not connected to the gas network has been unveiled.
The Off-Gas Grid Map is a new initiative aimed at tackling fuel poverty in the country.
The database aims to make it easier for organisations with the funding to target the fuel poor and connect them to the gas grid.
It will also enable local authorities and housing associations to identify areas and seek help.
The initiative is being spearheaded by DECC and the government’s Fuel Poverty Advisory Group and funded by National Grid Affordable Warmth Solutions.
Energy Minister Lord Bourne said: “As a one-nation government on the side of consumers, we are determined to ensure that hardworking families can keep their homes warm and their bills low. We know that people living off the gas grid are more likely to have difficulty with their energy bills and that’s why we are taking action to help people who need it the most.
“Along with our £25 million funding announcement this month to local authorities to tackle fuel poverty, we have also partnered with National Grid and industry groups to identify where these people are and the best way to help them.”
National Grid aims to connect 25,500 fuel poor homes to the gas network by 2021.
