Recommendation 1

The scale of the challenge to retrofit existing homes to tackle the climate crisis is enormous. Energy efficiency is a precursor to the transition to low carbon heat, so action must be taken in the 2020s to set homes on a decarbonisation trajectory to meet our net zero targets. The Government’s current targets for domestic energy efficiency are set for an 80 per cent reduction in emissions by 2050 and not the net zero target established in law. Yet the Government is not on track to meet even this.
