Our Severe Weather Emergency Protocol (SWEP) helps to protect and provide for vulnerable people sleeping rough during severe weather. 

SWEP is activated when there is a real risk of loss of life because of weather conditions, it must be applied when the night-time temperature is predicted to be zero degrees Celsius or below for three nights in a row. 

An occasional forecast above zero in a series of nights where the temperature is below zero should not stop SWEP from being activated. 

We will also consider: 

  • how rain, snow and wind chill affect the temperatures
  • exceptional weather, including extreme wind, rain, and flooding 

In the event of a Met Office Amber Warning or if severe weather is coupled with very low temperatures, we will decide whether SWEP should be activated. 

If a red warning is issued, then SWEP should be activated. 

Hot and cold weather help for people sleeping rough

Many people think about the risks of sleeping rough during winter, but it can be just as challenging during the summer months.

In hot weather, people sleeping rough may struggle to find drinking water, shade, and cool places to rest. Without somewhere safe to store belongings, some people carry heavy bags or wear extra layers, which can increase the risk of dehydration and, in extreme cases, heat exhaustion or heat stroke. In cold weather, the risks include exposure to freezing temperatures, and limited access to warm shelter, which can have serious effects on health and wellbeing.

If you see or know someone who may be sleeping rough, here are some simple ways you can help:

  • Stop and check in: ask if the person is ok
  • Offer practical support: in hot weather, this might include water, sun cream or an umbrella; in cold weather, warm drinks, food or extra clothing can help
  • Get professional support involved: contact StreetLink via their website or call 0300 500 0914. They will be able to connect them with local support services.
