Rishi Sunak scrapped energy efficiency targets to avoid a mass exodus of landlords in the private housing sector, an energy minister has revealed. In his controversial net zero speech last month, the prime minister rowed back on targets which were aimed at making rented properties more energy efficiency. This included a requirement for all landlords to upgrade their properties to meet the EPC (Energy Performance Certificate) Band C standard. Energy efficiency minister Lord Callanan has now revealed that fears of a landlord backlash sparked the move.
