Severe Weather Emergency Protocol SWEP is an emergency response to extreme weather (usually cold and snow) that is activated at short notice to get rough sleepers off the streets at a time when weather poses a significant risk to health. Usually, this takes the form of increased shelter accomodation on a short term basis. It is every local authority’s responsibility to ensure that adequate SWEP provision is made. Often, this will be done by engaging with services and community groups, via grant funding or contract provision. However, the planning and coordination of SWEP is the responsibility of the local authority. In London, the Mayor also provides additional SWEP services to ensure that even when the provision planned by local authorities is full anyone sleeping rough during extreme conditions can access shelter.
