Energy efficiency campaigners have slammed the government for again stalling its plans to upgrade privately rented properties across the country. Graham Stuart, minister of state for energy security and net zero, has confirmed that the government response to a consultation on higher energy efficiency standards for the private rented sector may not be published until the end of this year. That is despite a consultation on the proposed Private Rented Sector Minimum Energy Efficiency Standards (MEES) concluding nearly two years ago.
