The Foyer Federation is to adopt a new preventative approach to homelessness in a partnership with the Connexions youth service.
The Safe Moves project involves collaboration with statutory agencies including local authorities, the police, schools and Connexions in a bid to stop teenagers becoming homeless. Beneficiaries receive peer mentoring, family mediation and life skills training.
It marks a new departure for the charity, which is seeking to reach young people before they need accommodation in local Foyers.
The federation's new chief executive, Jane Slowey, said: "Safe Moves takes the holistic nature of the Foyer approach to the next level, considering young people's needs before they need us."
Agencies such as Connexions will refer teenagers at risk of homelessness to local Foyers.
An evaluation of a pilot scheme in four areas of England found that in two-fifths of cases, Safe Moves helped keep a young person in their parents' home.
