Calls for boiler phase-out date and incentives for heat pump switch Households face changes to the way homes are heated to tackle climate emissions (Steve Parsons/PA) A target date for phasing out boilers and grants to help people install heat pumps are needed to help cut emissions from heating homes, the Government has been told. Industry experts want similar measures to those being used to accelerate the drive towards electric cars, such as a phase out date in the 2030s and grants that bring down the cost of new technology. There are also calls to shift green levies away from electricity to make running an electric-powered heat pump a cheaper option for consumers.
