If you're in England and Wales then it's worth reporting anyone new you see sleeping rough. Street Link have a web page to let you do this which is mobile friendly and there are also apps for Android and iOS.
Background info from their web site:
> StreetLink is a website that enables the public to alert local authorities in England and Wales about people sleeping rough in their area.
> This service offers the public a means to act when they see someone sleeping rough, and is the first step someone can take to ensure rough sleepers are connected to the local services and support available to them.
