At least 260 homes will be made warmer after the city received a fuel poverty grant worth almost £6m.
Leeds City Council said £3.8m of the cash would pay for wall insulation, new doors and windows and low-carbon heating.
Upgrades are planned in privately-owned and rented housing, funding by the government’s Warm Homes Local Grant.
It is hoped the scheme will ease pressure on household heating budgets and reduce cold-related illnesses.
A council report said: “The scheme will also contribute to the physical and educational development of children by providing warm homes where they can socialise and study.”
Improvements would be available to low income households, including those with an annual income of less than £36,000 or claiming some means-tested benefits.
A contractor would be appointed via a competitive tendering process to carry out the project, paid for with part of a £5.9m grant received in March this year.
The report said “This procurement will enable £3.8m of government grant funding to be used to assist at least 260 private sector homes.
“The improvements will reduce residents’ fuel bills compared to what they otherwise would have been, reducing fuel poverty and leaving residents with more money to spend on other things.”
A contract is expected to be awarded in January next year and works carried out up until March 2028.
