Amber Heat Warning: Guidance for Homelessness Services

June 20, 2025

As we enter the summer months, it’s vital to prepare for the risks extreme heat poses—especially to people experiencing homelessness, who are disproportionately affected by hot weather.

People sleeping rough or in insecure accommodation face a heightened risk of heat-related illness due to limited access to shade, water, and shelter. Hot weather can quickly become a health emergency for vulnerable individuals, particularly those with underlying health conditions, mental health needs, or those using substances.

Key Heat-Related Illnesses to Watch For:

Heat exhaustion
Symptoms: sweating, pale skin, fast pulse, cramps, nausea, dizziness
What to do: move to a cool area, remove outer layers, apply cool water, hydrate, seek medical help if no improvement.

Heatstroke (emergency)
Symptoms: confusion, seizures, unconsciousness
What to do: call 999 immediately, cool skin with water, hydrate if conscious, place unconscious person on their side.

Tips for Staying Safe in the Heat:

  • Drink plenty of water—even if you’re not thirsty
  • Wear a hat and loose, light-coloured clothing
  • Use sunscreen or seek shaded areas
  • Avoid alcohol, caffeine, and strenuous activity
  • Spend time in air-conditioned buildings (e.g. libraries, day centres)
  • Eat salty foods to replace electrolytes lost through sweat

Recommendations for Homelessness Services:

  • Keep supplies of water, sunscreen, hats, and light clothing available
  • Extend opening hours during extreme heat
  • Map and share local ‘cool spaces’, water refill points, and accessible toilets
  • Display heatwave information in places frequented by those at risk
  • Work with local authorities to ensure coordinated SWEP (Severe Weather Emergency Protocol) responses
  • Increase daytime outreach to offer support and supplies

Key Resources:

Please also contact your Local Authority for borough-specific advice on SWEP arrangements and local resources.

Let’s stay informed and prepared to protect those most at risk this summer.
