The London Assembly Planning and Regeneration Committee told the Mayor on 29 July 2026 that the city must speed up retrofitting work to protect children from heat‑related illness. The committee’s report, released to MyLondon, says more than one million youngsters could be exposed to dangerous indoor temperatures if action is delayed.
Why overheating matters now
London Mayor urged to speed up home retrofitting to combat overheating
Assembly committee warns of risks to over one million children from rising temperatures.
Data from the Office for National Statistics shows London records the highest share of deaths linked to both extreme heat and cold. The Met Office warned that this summer could become the hottest on record, and that heatwaves above 40 degrees are now twenty times more likely than in the 1960s. These trends increase the urgency of improving housing resilience.
The Assembly’s cross‑party group of members calculated that 75 per cent of the capital’s social housing stock is at high risk of overheating. That figure translates into a large number of families with children, elderly people and vulnerable adults living in dwellings that cannot stay cool without active cooling systems.

The Met Office predicts heavy downpours and a risk of flash floods across the capital.
Committee chair James Small‑Edwards said the current pace of retrofitting is insufficient. He told members that designers often skip passive measures such as reduced glazing and external shading, opting for ventilation alone. Dr Tom Dollard added that passive solutions can carry higher upfront costs, leaving developers with little incentive when they do not retain long‑term responsibility for the building.
The report highlights a pilot programme where the Greater London Authority and London Councils are fitting shutters and awnings to 12,000 homes. Those measures reduce indoor heat without using electricity, while air‑conditioning is recommended only for households deemed vulnerable. The Assembly urged the Mayor to embed such passive cooling within broader retrofit schemes.
A spokesperson for the Mayor, speaking to the Local Democracy Reporting Service, said the Heat Ready London strategy and the draft new London Plan already aim to protect those most at risk. The spokesperson confirmed the mayor’s office will consider the Assembly’s recommendations as part of ongoing policy work.
Questions this report answers
+How many children could be affected by overheating homes?
The Assembly report says more than one million children in London could face health problems if homes continue to overheat. That estimate reflects the scale of the risk and underlines the need for rapid retrofitting to protect young residents.
+What share of social housing is at high risk of overheating?
Seventy‑five per cent of the capital’s social housing stock is classified as high‑risk for overheating, according to the cross‑party report cited by the Assembly. This proportion indicates that most council‑owned homes may need passive‑cooling upgrades soon.
+What actions does the Assembly want the mayor to take?
The Assembly urged Sir Sadiq Khan to accelerate passive‑cooling retrofits, embed overheating adaptation in wider retrofit programmes, and expand measures such as external shading, shutters and awnings. The goal is to reduce indoor temperatures without relying on energy‑intensive air‑conditioning.
