Islanders will receive up to £430,000 as part of the Universal Home Insulation Scheme (UHIS) to keep the cold at bay.
The scheme, which will be administered by the local council offers a range of free home insulation measures including loft and cavity wall insulation.
These measures can help households improve their energy efficiency, keep heating bills down and reduce fuel poverty.
Talking about the funding Keith Brown, Minister for Housing and Transport said: “The Universal Home Insulation Scheme is a successful scheme which, over the years, has delivered real savings to people in their homes across Eilean Siar.
“By offering free cavity wall and loft insulation, owners, private sector tenants and landlords can make sure their properties are saving energy and money by reducing the heat lost through draughts.
“I am delighted that every local authority is supporting this scheme. The Scottish Government is investing over £¼ billion over the next three years towards eliminating fuel poverty and UHIS is making a significant contribution to achieving that aim.
“UHIS also creates employment opportunities with contractors employing and contributing to local economies across Scotland to deliver the scheme.”
