A cold weather health alert is a warning issued by the UK Health Security Agency (UKHSA) and the Met Office when low temperatures are expected to increase health risks, particularly for the elderly and those with chronic conditions. The alert levels range from green (no action) to red (national emergency).
What do the cold weather alert levels mean?
The UKHSA cold weather alert system uses a colour-coded scale. A yellow alert means the weather is likely to impact the NHS and social care services, while an amber cold health alert signals a significant risk to life for vulnerable groups. A red alert is the highest level, indicating a national emergency with widespread impacts on health services. The practical takeaway: check the UK weather hub for your local alert level and prepare by keeping indoor temperatures at 18°C or above.
Who is most at risk during a cold weather warning today?
Anyone can be affected, but the highest risk groups include people over 65, infants under one year old, those with pre-existing heart or lung conditions, and individuals living alone or in poorly insulated homes. If you or someone you care for falls into these categories, check the Cold Weather Payment Checker to see if financial support is available. The NHS advises keeping warm, staying active indoors, and checking on neighbours during a government health warning today.
