Homes of the future: Government backs its first net zero house building project in Cambridgeshire - here's what makes them so green

There could be a 'zero-carbon' homes revolution across Britain, after a net-zero housebuilder received millions of pounds from the Government to hone its green technology.

Homes England, the Government's housing agency, has provided £3.9million of funding to Etopia Group, This is Money can exclusively reveal.

It builds extremely energy-efficient houses that could save homeowners up to £700 pounds on their bills each year.

It says the homes, which are precision-engineered in factories, save the same amount of energy over their lifetime as taking a car off the road for 35 years.

It is the first time that the Government has joined forces with a zero-carbon housebuilder, and comes at the beginning of the COP 26 conference, where world leaders will gather in Glasgow to discuss how they plan to address climate change.

Households account for 40 per cent of the UK's carbon emissions, according to the Committee on Climate Change.
