The new gas-free bungalows feature a range of measures to make them more energy efficient.
The homes, on Woodmoor View, off Laithes Lane, are fully accessible and include six two-bedroom and one three-bedroom bungalow which will all be managed by Berneslai Homes.
They feature electric air source heat pumps, providing heating and water, and high levels of insulation, preventing heat loss.
The homes are also solar panelled to generate electricity and have a battery system to store the electricity until it is needed, helping tenants save on their electricity usage.
Coun Robert Frost, cabinet spokesperson for regeneration and culture, said: “We all have a part to play in helping Barnsley to be net zero carbon by 2045 - protecting our borough for future generations.
“Together, we can reduce pollution, minimise waste, and support people to heat and power their homes, cars and businesses with affordable, sustainable energy.
“These new homes are an example of how we’re doing that and also providing high quality homes for tenants which will be more more affordable to heat.”
Amanda Garrard, chief executive of Berneslai Homes, added: “We’re delighted to see the completion of these new, gas free council bungalows, which will provide great energy-efficient homes for people in housing need.
“Alongside our work to develop new housing, we’re also improving our existing housing through targeted retrofit works to increase energy efficiency.
“We secured £1.7m earlier this year to upgrade insulation at 150 properties and we will continue to seek funding to extend this work as widely as possible.”
