Leitrim has been named Ireland’s coldest county to live in new report says

Leitrim has been named Ireland’s coldest county to live in, according to a report by Calor Gas which analysed average winter temperatures alongside the proportion of energy-inefficient homes across the country.

Leitrim topped the poll, scoring 200 on the Cold Homes Index. The county has one of the lowest average temperatures in the country and one of the highest concentrations of homes in BER bands D to G, which are considered the least energy efficient.

Cork, Carlow and Waterford however, were found to have some of the most energy-efficient homes in the country, with a smaller proportion of homes in the D-G bands and slightly warmer average temperatures during the winter months.

Oliver Kenny, Chief Commercial Officer at Calor Gas, commented on the findings, saying: “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 setups or offering new connections and a free boiler to ensure they’re energy efficient, we want to ensure no one is left out in the cold.

“While insulation and smart upgrades are important, the energy we choose to heat our homes also matters. Cleaner, renewable-ready options like Calor BioLPG give households the chance to cut costs, improve comfort, and lower their carbon footprint, without compromising on warmth.”
