Exclusive: Groups say chancellor needs to kickstart renewed drive to help cut bills and reduce emissions

In a letter to Jeremy Hunt, more than 20 organisations asked the government to set aside at least £6bn a year over the next decade to support an acceleration in insulating home and installations of heat pumps.
