The Scottish Government is to plough £470,000 from its Universal Home Insulation Scheme into Inverclyde - and householders are being urged to take advantage.
The cash means Inverclyde Council and its partners will be able to offer thermal insulation improvements to approximately 1,000 privates home.
Another 2,500 householders will also have the opportunity of benefiting from a free home energy report, billing advice, energy advocacy and energy efficiency advice.
Councillor Robert Moran, chair of LESS Inverclyde, said: "This provides an excellent opportunity for people to improve the energy efficiency of their home and to save money on their heating bills now and over the lifetime of the insulation.
"Our aim is to make Inverclyde's houses the most energy efficient in Scotland so I would encourage people to get in touch and apply."
Since it was launched in November 2008 LESS Inverclyde has already helped hundreds of householders who have had enough of high fuel bills.
Councillor David Wilson, who chairs the council's green charter group, said: "We are proud to say that we believe the LESS Inverclyde model to be the best service of its kind in the country.
"The funding secured from the Scottish Government combined with money from Scottish Hydro Electric means we can offer this fantastic free insulation deal to householders and for the first time offer financial help to those householders who can't have cavity wall insulation."
