Trade bodies that housing and care providers can choose to become members of on a voluntary basis. These organisations generally have a code of practice that their members must follow and any breach of this code can be challenged by the trade body.

Some of the most common trade bodies are:

Association of Retirement Housing Managers (ARHM)
Associated Retirement Community Operators (ARCO)
Association of Residential Managing Agents (ARMA)
National Care Forum (NCF)
