Under the new regulations, CO2 emissions from new build homes must be around 30% lower than current standards and emissions from other new buildings, including offices and shops, must be reduced by 27%.

Heating and powering buildings currently makes up 40% of the UK’s total energy use.

Installing low carbon technology, such as solar panels and heat pumps, and using materials in a more energy efficient way to keep in heat will help cut emissions – lowering the cost of energy bills for families and helping deliver the UK’s climate change ambitions.

All new residential buildings, including homes, care homes, student accommodation and children’s homes, must also be designed to reduce overheating, making sure they are fit for the future and protect the most vulnerable people. Improvements to ventilation will also be introduced to support the safety of residents in newly-built homes and to prevent the spread of airborne viruses in new non-residential buildings.

Housing minister Eddie Hughes said the changes announced to the government’s Building Regulations, which set the standards in England for the design, construction and alteration of buildings, follow a public consultation and will come into effect from June 2022.

They will raise standards and are an important step towards a cleaner greener built environment, paving the way for the Future Homes and Buildings Standard in 2025, which will mean all future homes are net zero ready and will not need retrofitting, he added.

Mr Hughes said: “Climate change is the greatest threat we face and we must act to protect our precious planet for future generations.

“The government is doing everything it can to deliver net zero and slashing CO2 emissions from homes and buildings is vital to achieving this commitment.

“The changes will significantly improve the energy efficiency of the buildings where we live, work and spend our free time and are an important step on our country’s journey towards a cleaner, greener built environment.”
