The One With… the Housebuilder Seeking To Decarbonise 8500 Homes A Year

Bellway builds around 8,500 homes a year — and a large share of its carbon footprint comes not from construction, but from the homes people live in after they buy them. Jamie Bursnell, Group Head of Technical and Innovation at Bellway Homes, has spent years working out how you actually decarbonise a new home at scale. His conclusions upend a few assumptions. The gas boiler won't be banned — the compliance tool will simply make it impossible to build with. And the hardest problem isn't technology, it's pricing: with electricity roughly three times the cost of gas, the greener home can cost more to run, and no politician wants to move that cost.
