Watford Borough Council plans to help local residents to access cheap energy rates through a variety of insulation offers.
The council has £440,000 of government money to help provide free and discounted home insulation for lofts and cavity walls which will help to retain heat and reduce energy bills.
Insulation also helps reduce the amount of greenhouse gases released into the atmosphere and the council plans to cut local emissions by nearly 50,000 tonnes this year.
Councillor Derek Scudder, the cabinet member responsible for the environment, said: "The action plan clearly sets out tasks and initiatives that will enable the council to remain a leader of the community in this arena."
Fitting insulation to both cavity walls and lofts could bring savings of up to £370 a year, while also saving nearly 2,000kg of carbon dioxide.
Many households living in fuel poverty will be entitled to free insulation.
Last autumn, the prime minister decided against a windfall tax on energy suppliers and instead opted to support nationwide energy efficiency.
