Grants are up for grabs to make homes across Middlesbrough greener, cleaner and cheaper to run.
Middlesbrough has been awarded more than £1 million in the latest phase of the Government's Green Homes Grant scheme.
The cash will help qualifying residents with energy-saving improvements worth up to £10,000.
The drive - in partnership with utilities giant E.ON - offers free energy-efficient installations such as air source heat pumps, solar panels and external wall and loft insulation.
The scheme is open to those whose annual household income is less than £30,000 and whose property has an energy efficiency rating of D, E, F, or G.
Landlords may also be eligible for a grant of up to £5,000 for improvements, but will be required to make a contribution towards the total cost.
Councillor Barrie Cooper, Middlesbrough Council's Executive member for Environment, Finance & Governance, said: "These are tough times for all of us, so this is a fantastic opportunity to save on household fuel bills and be more environmentally friendly.
"The work is absolutely free, and will benefit many homes across the borough.
"I'd urge anyone who thinks they might qualify to contact E.ON straight away - the scheme ends in March but it's first come, first serve so there's no time like the present."
