Party donor Dale Vince warns that urging homeowners to switch to clean-power technology risks political storm bigger than Ulez

The government risks a huge political backlash if it keeps pushing the public to install heat pumps to replace their boilers, one of Britain’s leading green entrepreneurs has warned.

Dale Vince, a major Labour donor and renewable energy advocate, called on Keir Starmer to rethink national programmes, championed by Boris Johnson, pushing the technology. Vince argued that Whitehall should explore alternatives to the devices, which he said were expensive, caused serious disruption and could end up increasing energy bills for some people.
