Residents are in line for free energy improvements over the course of this year following successful funding bids totalling almost £2.7 million.
A government green homes grant of £920,000 has been secured by Hertsmere Borough Council and Three Rivers District Council, with a further £1.758 million secured by Watford Borough Council and Three Rivers District Council.
It means owners and tenants in more than 300 energy inefficient homes will be offered the chance to have home improvement measures, such as external wall insulation, floor insulation and high retention storage heaters installed in their properties.
The measures, worth up to £10,000 per household, could help residents save up to £500 on their energy bills per year.
For landlords of qualifying households, grants will be available for measures worth up to £5,000.
Hertsmere Borough Council says the funding represents an important next step towards tackling fuel poverty, reducing energy use and lowering carbon emissions for all three local authorities, with the council committed to achieving zero carbon emissions no later than 2050.
Councillor Seamus Quilty, portfolio holder for the environment in Hertsmere, said: "This initiative is a wonderful opportunity for dozens of eligible householders to reduce their bills and help make sure their homes are as warm and comfortable as they can be.
"However, the pay-offs are greater than that even. This initiative will help us as a borough reduce our carbon footprint and move a step closer to achieving our commitment to tackling climate change.
"By making these significant improvements to local homes, we will help tackle fuel poverty, bring down carbon emissions and ultimately, benefit everyone in the future."
The council says it will soon be publishing further information on how residents can access funding for home improvements.
