Updated HSE guidance focuses on passive cooling strategies in pre-1980s buildings where mechanical cooling is impractical. Includes trigger thresholds for resident welfare monitoring.
Overheating used to be treated as a comfort complaint rather than a safety risk, but CQC now treats sustained high internal temperatures as an environmental safety factor under the safe premises standard. Older residents, particularly those on certain medications or with cardiovascular and respiratory conditions, are far more vulnerable to heat stress than the general population. Where a home cannot demonstrate that it monitors and responds to high temperatures, an inspector can reasonably ask what the provider is doing to protect residents during a heatwave.
Many care homes occupy converted period buildings or 1960s-1980s purpose-built stock with limited insulation control, single-glazed or poorly shaded windows, and no mechanical cooling. These buildings often retain heat overnight, so bedrooms can stay hot even after outside temperatures drop. Retrofitting full air conditioning is rarely practical or affordable, which is why HSE guidance for this building type focuses on passive measures -- shading, ventilation, and fabric performance -- rather than assuming mechanical cooling is the default solution.
Practical passive strategies include external shading or shutters on south and west-facing windows, reflective or thermal blinds, secure night-time ventilation using restrictor-compliant window openings, and reducing internal heat gains from lighting and equipment during peak hours. Where mechanical cooling is fitted, it should be targeted at the highest-risk rooms -- lounges, dining areas and bedrooms of residents identified as heat-vulnerable -- rather than relying on whole-building air conditioning that may be absent or insufficient.
HSE-aligned good practice is to record room temperatures in high-risk areas at set times during warm weather, with a defined trigger point at which additional action is taken -- increasing fluid offers, opening restricted windows for ventilation, moving residents to cooler communal areas, or escalating to management if temperatures do not fall overnight. A simple temperature log, even using standard thermometers, gives you a documented response trail that shows the risk was actively managed rather than ignored.
Overheating risk should sit alongside your existing environmental checks rather than as a standalone summer exercise. Identify residents at higher risk from heat -- those with dementia who may not recognise or communicate discomfort, those on diuretics or antipsychotics, and those with limited mobility -- and note this in care plans so staff know who to check on first. Reviewing this annually before the warmer months, and keeping records of any remedial action taken, is the clearest evidence you can offer CQC that overheating is being actively managed as a safety issue.
