Research conducted by Calor has led to the launch of its energy efficiency initiative, known as Future of Rural Energy England (FREE).
This shows that Suffolk, Northumberland and Nottinghamshire contain the most fuel poor rural areas in England.
The LPG supplier worked with the Commission for Rural Communities to match fuel poverty data with areas of England that are off mains gas, the company states.
Further analysis showed that Forest Heath (Suffolk), Berwick-upon-Tweed (Northumberland) and Bassetlaw in Nottinghamshire contain the highest percentage of fuel poor households in off-mains gas England.
The launch of the initiative has been further supported by the creation of a Heat Map of England.
Calor states that the research has been compiled for the first time to highlight the complexities associated with living off mains gas in Great Britain and demonstrates that rural fuel poverty is often very different from urban fuel poverty, both in root causes and solutions.
The research is all part of its new three year £1 million initiative to help tackle fuel poverty and promote energy efficiency in off-gas grid communities.
The initiative is designed to help households understand the full range of options open to them with regard to cost savings, new technologies, income maximisation and carbon reduction methods and encourage local communities to work together to promote best practice.
Calor will be working with fuel poverty charity National Energy Action (NEA) and the Rural Community Action Network across England (ACRE) to fund regional energy officers (REOs) who will offer independent information and advice to off-gas grid households and communities to help improve energy efficiency and reduce their carbon footprint.
