My Lords, in August of last year BEIS launched the electrification of heat demonstration project, which will, hopefully, demonstrate the feasibility of large-scale transition to electrification of heat in our homes by installing heat pumps in a representative number of homes. There are currently 1,800 qualified heat pump installers in the UK, but we know that to reach 1 million homes we need 40,000 installers. The industry is currently assessed as having the capacity to train 5,000 to 10,000 new installers a year—so this, hopefully, is within our grasp.
