A failure to move quickly enough on the UK’s net zero targets could have added up to £2,150 to household bills in 2022, new research has found. The Energy and Climate Intelligence Unit (ECIU) examined the impact of delays in deploying renewables, insulation, rooftop solar panels, heat pumps and electric vehicles. It concluded that for the UK as a whole, the costs of a slower path to net zero could be in the region of £39 billion.
