Amber Valley Borough Council is making 180 homes cleaner and greener as part of a government scheme to fund and promote energy efficient housing.
The £1.2M government green home grant spending has already started with retrofit improvements in key areas of the borough.
Council leader, Councillor Kevin Buttery said: “Climate change presents us with a huge challenge to ensure the energy we use is greener and our homes are fit for the future.
“Making our homes more energy efficient will reduce carbon emissions, improve health and cut bills.
“The green homes grant from the government is a fantastic opportunity for our residents to save money on a home improvement which will save them money year-on-year.
“They will be helping to reduce residential carbon emissions across the borough and get the council closer to the overall goal of being carbon neutral by 2030.”
Cllr Buttery said the scheme was supporting employment in the borough by using a local contractor to complete the work.
Retrofit improvements have started on selected Ironville houses in Market Street, Market Place and Queen Street.
Energy-efficient features like external wall, loft and cavity wall insulation are being added.
The council is now looking to expand the scheme to Walker Avenue, Stanley Avenue, Redfern Avenue and Fletcher Street in Ripley and will contact each household directly
Tenants and owners living in any of these specific streets in Ripley may be eligible as part of the scheme.
The council said landlords may qualify too but will need to contribute a third towards the cost of any energy-saving improvements.
Cllr Buttery said the council has always been committed to supporting eco-friendly and sustainable projects.
He said: “Schemes like the affordable warmth project for homes, addressing climate change and the central help from the government to boost energy efficiency are key to the council’s overall vision.”
Deputy leader and cabinet member for housing and health, Councillor Paul Hillier said: “This initiative is part of our continuing work to help improve the energy efficiency of housing stock across the borough.
“I am also looking at a small scheme planned in Belper to offer external wall insulation to 16 properties and all the properties have been provided application forms.
“Funding is limited to our £1.2million budget and there will be no obligation for the property owners to accept the offer for insulation improvements, but I hope as many as possible do so.”
The council will handle the applications for planning consent related to the improvements.
