The role of each dutyholder
Domestic clients
A domestic client means a client for whom a project is being carried out which is not in the course or furtherance of a business of that client.
Main duties – what they must do
Where there is more than one person working on different aspects of the project, a Domestic Client should appoint a Principal Designer to be in control of design work and a Principal Contractor to be in control of the building work.
If a Domestic Client does not appoint either a Principal Designer or Principal Contractor, then the designer in control of the design phase of the project is the principal designer and the contractor in control of the construction phase of the project is the principal contractor.
Must provide building information that they have, or it would be reasonable for them to obtain, to designers and contractors working on the project.
Must cooperate with anyone working on or in relation to the project to the extent necessary to enable them to comply with their duties or functions.
The responsibilities of Clients other than Domestic Clients can be found further down this document.
