Gas hobs or boilers should be banned from being installed in new homes within the next six years, government advisers have recommended.

A report by the Committie of Climate Change (CCC) says that from 2025 at the latest, no new homes should be connected to the gas grid – with super-efficient houses and flats heated using low-carbon energy instead.

It also warns that UK homes are not fit for the future, with efforts to cut greenhouse gases from housing stalling and properties at growing risk of overheating and flooding.

The committee called on the government to get serious about tackling emissions from homes and ensuring they are adapted to cope with a future of more extreme weather.

The way new homes are built and existing properties are “retrofitted” with energy efficiency measures often falls short of stated design standards, deceiving householders and inflicting costs on the future, the committee said.

Closing the “performance gap” between design standards and what is achieved could save those in new homes between £70 and £260 a year on their energy bills, the report said.

Cash-strapped councils need better funding to help enforce building standards and there should be stiffer penalties for non-compliance it said. The Treasury should support, as a “major infrastructure priority”, measures in existing homes to install low-carbon heating such as heat pumps, loft and wall insulation, and protection for properties at risk of flooding.

Support is also needed to train designers, builders and installers of climate-friendly technology to address the low-carbon skills gap and create green jobs.
