Yes. An individual or company can discharge more than one CDM 2007 function provided they have the appropriate level of competence. It is not necessary for individuals or companies with CDM 2007 duties to be independent of one another, but they must be able to exercise sufficient independence within the role to carry out the role effectively. For example, clients may decide to discharge the co-ordination duties themselves or they may appoint the lead designer as the co-ordinator. It is possible for all the duties to be discharged by the same company. However, an appointment of a co-ordinator and principal contractor for notifiable jobs must be made.
