Cold homes, winter illness and the case for healthy housing as a health intervention
Every winter, health services across the UK face a predictable rise in respiratory illness, exacerbations of long‑term conditions and avoidable hospital admissions. While clinical teams work tirelessly to manage this seasonal surge, one of the most powerful levers for reducing winter pressure lies outside the clinical environment. It lies in the homes of the people most at risk.
Cold, damp and poorly insulated homes are not simply a social issue. They are a clinically significant determinant of health. For people living with chronic illness, older adults, families in poverty and those with disabilities or vulnerabilities, the home environment can be the difference between stability and crisis. Recognising and addressing this is essential if we want to reduce avoidable illness, improve long‑term outcomes and ease pressure on frontline services.
The scale of the issue is stark. UKHSA estimates that extreme cold weather contributed to 5,533 deaths in winter 2022–23. Around 10% of excess winter deaths are directly attributable to fuel poverty and 21.5% are attributable to cold homes.
The NHS is estimated to spend at least £2.5 billion per year treating health conditions directly linked to cold, damp housing. Modelling suggests that cold‑associated deaths are likely to peak around 2030, meaning the problem is not only persistent but worsening.
We know that our services give positive health outcomes.
Health professionals are already familiar with the physiological effects of cold exposure, but the cumulative impact on fuel‑poor households is profound. There is consistent evidence that temperatures below 18°C are associated with negative health effects and this is the threshold at which risks begin to rise.
Cold homes contribute to:
Cold homes also affect behaviour and daily functioning. People move less, sleep poorly and may avoid using certain rooms. Those with dementia or Alzheimer’s may not recognise that they are cold, increasing their vulnerability.
Damp and mould are widespread, affecting between 4% and 27% of UK homes. The causes are often structural: inadequate ventilation, leaks, poor insulation and condensation. When homes are under‑heated, moist air condenses on cold surfaces, and when windows are kept shut to save on energy bills, mould thrives.
The health impacts are significant. Damp and mould are associated with:
People with common mental disorders (CMD) are disproportionately affected: 15% report mould in their homes, compared with 8% of those without CMD.
Home energy efficiency measures have been shown to reduce school absence due to asthma and recurrent respiratory infections, demonstrating the direct health benefits of improving the home environment.
Cold homes and fuel poverty are strongly linked with poor mental health, including depression, anxiety and reduced educational and employment attainment. One in ten people with common mental disorders report being unable to keep their home warm, compared with just 3% of those without CMD.
Cold homes also drive social isolation. People are reluctant to invite friends or family into a cold house and this isolation can deepen existing mental health challenges. Research suggests that more than one in four adolescents living in cold housing are at risk of developing mental health conditions, compared with one in twenty who have always lived in warm housing.
There are also safety risks. Poorly maintained or poorly ventilated gas boilers and combustion appliances increase the risk of carbon monoxide poisoning, a concern particularly relevant to off‑gas and rural households.
In Devon, the impact of cold homes is particularly acute. Our county has a high proportion of older residents, a large rural population and some of the lowest average incomes in the South West. Many homes are off‑gas, hard to heat or poorly insulated, and long travel distances can make accessing healthcare more challenging. Coastal damp, older housing stock and pockets of deep rural poverty all contribute to higher rates of respiratory illness and winter vulnerability. For the people we support across Exeter, East Devon, Mid Devon, Teignbridge and Torbay, the home environment is often the single biggest factor shaping their health and stability. By working together across health, housing and community sectors, we can reduce illness, support safer discharge and ensure that more Devon residents can live in warm, healthy, resilient homes.
At ECOE Advice, we work directly with households experiencing fuel poverty and vulnerability. Our approach is practical, relational and designed for long‑term impact.
We visit people in their homes, taking the time to understand the real conditions affecting their health. This allows us to identify the root causes of cold, damp and mould — whether structural, behavioural, financial or a combination. Our support includes:
This hands‑on, personalised model helps stabilise long‑term conditions, reduces winter illness, and supports safer hospital discharge. It also builds trust, confidence, and resilience within households that often feel overlooked or unsupported.
We know that winter places extraordinary pressure on health services. We also know that many of the patients who return repeatedly with respiratory illness, frailty or chronic condition flare‑ups are living in homes that are making them unwell.
We can help.
If you are a GP, practice nurse, social prescriber, respiratory specialist, frailty practitioner or part of a hospital discharge team, we invite you to work with us. Together, we can reduce admissions, support better management of long‑term conditions and address the root causes of health inequalities.
Warm, healthy homes are not a luxury. They are a foundation for good health and a vital part of our shared winter resilience strategy.
