HEARTH Stakeholder Workshops September–November 2025

Between September and November 2025, HEARTH ran four case-setting focused stakeholder workshops on homes, prisons, hospitals, and care settings. Collectively, the workshops brought together practitioners, policymakers, researchers and third-sector organisations from across the UK with the intent to:

• Examine the prevalence of overheating in the settings and its health implications.

• Present (net zero) strategies and measures for enhancing heat resilience.

• Discuss specific tools and guidance for addressing overheating.

• Explore research and collaborative opportunities in this field.

In detail:

• Homes Workshop - 30 attendees, including nine speakers from Greater London Authority,  Oxfordshire County Council (OCC), Edinburgh City Council, National Retrofit Hub, UK Passivhaus Trust, National Energy Foundation, Inkling, Public Health Scotland, LSHTM.

• Prisons Workshop - 34 attendees, including 11 speakers from Ministry of Justice (MoJ), HM Prison and Probation Service (HMPPS), Met Office and Mace, University of Surrey, LSHTM, OBU.

• Hospitals Workshop - 30 attendees, including seven speakers from Greener NHS, Sussex Community NHS Foundation Trust, LSHTM.

• Care Settings Workshop - 33 attendees, including eight speakers from GLA, CIBSE, Architype, UCL, UoL, LSHTM.

Across all four workshops, discussions focused on:

• How extreme heat is currently experienced in each setting.

• Barriers and opportunities for low-carbon, climate-resilient design and operation.

• Immediate and longer-term priorities for HEARTH research and policy engagement.

• Outputs from these workshops are now informing HEARTH workplans and future engagement activities.
