The Hôpital Franco-Britannique is a committed member of the West Paris Hospital Alliance.

Six independent institutions, six private establishments (ESPIC), all originating from a recognised public interest foundation or association, each having a philanthropic background, joined forces in September 2017 to form the West Paris Hospital Alliance. It was originally composed of the Hôpital Foch in Suresnes (MCO), the Hôpital Franco-Britannique in Levallois-Perret (MCO), the Cité des Fleurs (SRR), the Hôpital Gouin (SSR), the Fondation Diaconesses de Reuilly (palliative care), and the Fondation Santé Service (home-care), over the years the alliance has been constantly strengthened. Consequently a number of EHPAD (Somemnes), home-care nursing associations (SESID, SAPA, ANSIAD, SSID in the West of the Hauts-de-Seine department) and hospitals (Hôpital Nord 92, MGEN institutions) have joined the West Paris Hospital Alliance, which is now the largest private non-profit healthcare group in the Ile-de-France region. It has become a genuine local powerhouse for public health in the Hauts-de-Seine department.
