All new homes must have a heat pump and most a renewable energy source from 2028, the government has said.
Today the government published the details of the Future Homes Standard, meant to make homes greener and more energy secure.
The Future Homes Standard was first announced in 2019 and was meant to be launched in 2025.
New builds will need heat pumps, improved airtightness and wastewater heat recovery.
Most will also have a form of renewable energy generation, most likely solar panels, unless a building is high-risk, the roof is unsuitable or the site is too shady.
The government said that residents of new homes from 2028 could save £830 per year on energy bills, while the new buildings will produce 75% less carbon than those built in 2013.
The changes will be enforced through new building regulations from March 2027, though there will be a year-long transition period.
The Future Homes Standard also lays out how homes can sign up to heat networks and advice on greener heating.
Energy secretary Ed Miliband said: “The Iran war has shown our drive for clean power is essential for our energy security so we can escape the grip of fossil fuel markets we don’t control.
“Whether through solar panels fitted as standard on new homes or making it possible for people to purchase plug-in solar in shops, we are determined to roll out clean power so we can give our country energy sovereignty.”
Housing secretary Steve Reed said: “As we make the switch to clean, homegrown energy, today’s standard is what the future of housing can and should look like.
“Not only will these changes protect hard-working families from shocks abroad but will also slash hundreds of pounds off their energy bills every year.”
