UKHSA issues amber and yellow heat-health alerts across England
18 Jun 2026 04:21 PM
An amber heat-health alert is now in place for East of England, South East, South West and London regions.
The UK Health Security Agency (UKHSA) has issued an updated heat-health alert (HHA) for parts of England, warning that rising temperatures may increase health risks, particularly for vulnerable groups.
An amber heat-health alert is now in place for the East of England, South East, South West and London until 8pm on Tuesday 23 June.
A yellow heat-health alert is in place for the West Midlands and East Midlands during this time. Other regions of England are currently unaffected.
Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said:
Sustained periods of warm weather can result in serious health outcomes, especially for older adults, and it is therefore important that everyone takes sensible precautions while enjoying the sun.
We are urging health and social care services in affected regions to ensure they are prepared, and reminding people to look out for elderly relatives, neighbours, and those with underlying health conditions, making sure they are aware of the forecast and following the necessary advice.
Simple steps such as staying hydrated, avoiding the sun during the hottest part of the day, and keeping your home cool are some of the key ways to help keep yourself and others safe during periods of hot weather.
UKHSA guidance on staying safe in hot weather is available online. There you can find a full list of the groups who are especially at risk, as well as advice on keeping yourself and others safe during periods of hotter weather, such as:
- keeping your home cool by closing windows and curtains in rooms that face the sun
- try to avoid direct sunlight, especially between 11am and 3pm when UV levels are highest. If you do go outside, cover up with suitable clothing, such as an appropriate hat and sunglasses, and seek shade and apply sunscreen regularly
- if you are going to do a physical activity (for example, exercising or walking the dog), plan to do these during times of the day when it is cooler, such as the morning or evening. Also check weather forecasts to see when it will be cooler
- knowing the symptoms of heat exhaustion and heatstroke and what to do if you or someone else has them
