The rollout of heat pumps across the UK must not undermine the importance of home insulation, a leading think tank boss has said. Speaking to Utility Week Lucy Yu, chief executive at the Octopus Energy-backed thinktank the Centre for Net Zero, agreed that work should be done to remove barriers preventing people taking up heat pumps but urged caution around dismissing insulation measures. It comes after the Department for Energy Security and Net Zero announced it is considering changing the eligibility criteria for the Boiler Upgrade Scheme by removing rules around loft or cavity wall insulation.
