LABOUR councillors want to turn every house in Kirklees into an energy- efficient home.
And they have pledged £6m for their pioneering Warm Zones Plus scheme.
The plan, which will be included in the Labour Group's proposals for the Kirklees Council budget, will see the money invested over the next three years.
They want to ensure every property in Kirklees is better insulated to reduce heat loss, tackle rising energy bills and reduce greenhouse gas emissions.
And for most households, the work will be done free of charge.
Only those on higher than average incomes will pay and discounts will still apply.
Clr Mehboob Khan, leader of Kirklees Labour Group, said: "Our £6m investment will provide an enhanced scheme so that everyone can benefit from the latest energy efficiency measures.
"I believe that Warm Zones, working together with local communities, can provide something for everyone.
"Much of the work with warm zones is about installing measures - thermal insulation, draught-proofing and heating to improve comfort in the home.
"At the same time, sound advice on energy efficiency and benefits entitlement can help to reduce the amount spent on energy and maximise household income.
"Our plan is to help every household to reduce energy consumption and play their part in saving the environment.
"Together with increased green bin and glass collections, Warm zone Plus will help to make Kirklees the greenest borough in the country."
Schemes included in the submission are:
* Free or low cost insulation
* Free central heating measures will be available, subject to need, location and available funding, for households in fuel poverty or on certain qualifying benefits.
* Doorstep assessments to determine need
* Discounted schemes for the small number of households that do not qualify for free measures.
Labour councillors are expected to reveal their plans for Council Tax increases within the next few days.
Proposals by the Tory group suggest a 3.5% increase in council tax bills.
The budget meeting is on February 28.
