Study finds that Roscommon is one of the coldest counties in Ireland to live in

New research has revealed that homes in County Roscommon are among the coldest and least energy-efficient in Ireland — making it one of the hardest places in the country to keep warm.

The study, carried out by BioLPG experts Calor Gas, analysed average winter temperatures alongside the proportion of homes in energy efficiency bands D to G, to create Ireland’s first Cold Homes Index.

The findings showed that Roscommon ranked ninth nationally, with a Cold Homes Index score of 158, meaning local homes lose heat faster and cost more to heat compared to other parts of Ireland.

The research highlighted how older housing stock, rural locations, and colder average temperatures contribute to heat loss and higher heating bills for residents across the county.

While many counties in the west and midlands struggle with similar challenges, others like Cork, Carlow and Waterford are faring much better, with a smaller proportion of energy-inefficient homes and slightly warmer winter climates.

“This data shows that where you live in Ireland can make a huge difference to how warm and comfortable your home feels and how much you’re spending on heating.

“At Calor, we’re committed to helping households, especially in rural areas, access more efficient heating solutions like BioLPG. Whether it’s through modern gas systems, renewable-ready set-ups or offering new connections a free boiler to ensure they’re energy efficient, we want to ensure no one is left out in the cold,” commented Oliver Kenny, Chief Commercial Officer at Calor Gas.
