Oxfordshire County Council calls for government funding to cool down homes

Oxfordshire County Council has called on the government to introduce a Cool Homes Grant to retrofit vulnerable homes at risk of overheating in extreme heat.

Over recent years, heatwaves have become increasingly frequent, posing significant risk to Oxfordshire residents in unsuitable housing. Without appropriate adaptations in homes, higher temperatures can increase the risk of heart attacks, stroke, lung disease and severe mental illness.

In summer 2025, there were 1,504 heat-associated deaths in the UK. The council believes that these deaths are unnecessary and avoidable. Now experts estimate that more than 2,700 people may have died due to heatwaves in England and Wales so far this year.

Under the Warm Homes Local Grant, the council currently receives funding from central government to install adaptations in homes to retain heat in winter. However, there is no funding specifically designed to support the retrofit of homes that suffer from overheating.

Councillor Laura Gordon, Oxfordshire County Council’s Cabinet Member for Environment and Economy, said: “England recorded its warmest June on record, with another heatwave hitting just two weeks later. This is not a one-off occurrence, but a new reality to which the UK must adapt.

“This is also a health inequalities issue, where those most at risk from heatwaves are often least able to afford effective home adaptations to prevent overheating, while also being more likely to have pre-existing health conditions, mobility limitations or social isolation. Without targeted investment there is a risk that climate adaptation widens health inequalities.

“Oxfordshire County Council is already working to address risk, and this summer will launch its pilot Heat Safe Homes programme. This will provide advice through home visits, local cool home training, community engagement, and the provision of cool packs. We are calling for central government support to expand this work to the scale needed to meet the challenge.”

The council believes that the government should consider expanding this Warm Homes Local Grant to include a Cool Homes Grant to protect our most vulnerable residents from overheating in their homes.

This grant would be used to help install passive and active cooling measures in vulnerable homes that are unable to afford them. External window shutters, blinds, improved ventilation, awnings, and air conditioning could all support these homes to be safe and liveable in summer.

The council has also called for the government to review current planning policies and building regulations which are currently constraining the uptake of external shading and ventilation measures.
