The Council is set to upgrade council homes on the Balmoral estate by installing new ground source heat pump systems.
The heat pumps will help to cut energy bills, reduce carbon emissions and provide more efficient heating for residents.
The council has secured £3.47 million through the Government's Warm Homes: Social Housing Fund (SHF) Wave 3 and is matching this through the Housing Revenue Account, which is used to maintain and improve council homes.
Kensa has been appointed as the principal contractor to design and install the new heating system and to support resident engagement throughout the project.
Ground source heat pumps use natural heat from the ground to provide a low carbon, energy efficient heating and hot water system. This upgrade will support residents with more stable long-term energy costs and contribute to the city's wider climate commitments. Works will begin later this year, with support provided to residents throughout the transition.
Cllr Anne Jones, Cabinet Member for Planning and Housing, said: "This investment will improve heating efficiency for tenants and help reduce household energy costs.
"Ensuring our homes remain safe, reliable and fit for the future is a key priority, and this upgrade forms an important part of that ongoing work."
Cllr Lydia Hyde, Cabinet Member for Climate, Environment and Waste, said: "This innovative technology is a major step forward in our ambition to cut the City's carbon emissions. Rather than burning gas extracted from hundreds of miles away, we can use the natural heat beneath our feet to warm our homes.
"With only a shoebox‑sized unit needed in each property to share this heat, we can deliver greener and cheaper heating to high‑rise homes for the first time."
