Mayo named one of Ireland’s coldest counties to live in

New research has revealed that homes in Mayo 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 show that Mayo ranks fourth nationally, with a Cold Homes Index score of 176, meaning local homes lose heat faster and cost more to heat compared to other parts of Ireland.

The research highlights 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.

Oliver Kenny, Chief Commercial Officer at Calor Gas, commented: “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."
