Heat pumps, electric cars and AI power demand: the gap between the pathway and delivery.
Britain is being asked to commit its homes, transport, electricity networks and countryside to a pathway whose delivery assumptions are under growing strain. The sharpest warning is in heating: installations have fallen when the model requires a steep acceleration.
The latest official UK retrofit figures record 20,895 installations in January–June 2026, down 22% on a year earlier. Doubling that half-year result gives an annualised pace of 41,790. The CCC’s required annual retrofit rate of 450,000 by 2030 is about 10.8 times that pace. This annualisation illustrates the scale of acceleration required; it is not a full-year forecast.
Zero-emission vehicles represented 5.2% of the licensed road-using fleet in June 2026. Our critique also examines company dependence in new EV registrations, gas heating in new house records, reduced Warm Homes Plan grants and government’s requirement for 6 GW of AI data-centre capacity by 2030.
Official bodies have published warnings. This critique asks ministers to reconcile those warnings with their promises, funding, consumer demand, power supply and costs. The evidence and its dates are set out in the eight pages below.
