CDM 2015 defines a client as anyone for whom a construction project is carried out. The regulations apply to both domestic and commercial clients, and all construction projects no matter who they are carried out for.
A commercial client is an organisation or individual for whom a construction project is carried out in connection with a business, whether the business operates for profit or not. Examples of commercial clients are schools, retailers, landlords and developers. This guide is aimed at commercial clients.
You are a domestic client if you are having work carried out which is not connected with running a business. Usually, this means arranging for work to be carried out on the property where you or a family member lives. If you are a domestic client, some of the client duties will transfer to other members of the project team.
