Housing association groups Accord and GreenSquare are exploring a possible partnership.
Talks will take place over coming months to see what such a partnership might achieve.
Accord chief executive Dr Chris Handy said: "Accord’s Board is always assessing opportunities that present themselves and early discussions with GreenSquare have shown that our organisations are very well aligned."
Ruth Cooke, GreenSquare's chief executive, said: "A partnership between Accord and GreenSquare could provide an excellent opportunity for both organisations to expand and enhance services to customers. Although conversations are at an early stage, I am looking forward to exploring what might result from us combining our strengths."
Accord is one of the largest housing and social care organisations in the Midlands; it provides 13,000 affordable homes and supports around 80,000 people with health and social care. The group's headquarters are in West Bromwich.
GreenSquare, based in Chippenham, owns and manages 12,000 homes in Wiltshire, Oxfordshire and Gloucestershire. Its focus is on providing homes and landlord services for those who cannot afford to meet their housing needs in the open market; building new homes for sale helps fund more social homes and improved services.
