A heat circuit breaker for the UK

This report marks the start of the National Heat Resilience Commission’s work. It explains the context for establishing the Commission and its mandate of providing independent expertise and strategy on how the UK can improve resilience to the growing risk of high temperatures.

The report is published alongside Phase 1 of the Commission’s Call for Evidence. This phase is aimed at businesses, public bodies, institutions, and voluntary and community organisations across the UK with relevant evidence, experience or insight.
