Duty Holder Appointment Letters

Appointment of the Principal Designer (PD) & Principal Contractor (PC)

Where there is more than one contractor, or if it is reasonably foreseeable that more than one contractor will be working on a project at any time, the client must appoint in writing:

(a) a designer with control over the pre-construction phase as principal designer; and

(b) a contractor as principal contractor.

  • The appointments must be made as soon as is practicable, and, in any event, before the construction phase begins.
  • If the client fails to appoint a principal designer, the client must fulfil the duties of the principal designer in regulation 11 and 12.
  • If the client fails to appoint a principal contractor, the client must fulfil the duties of the principal contractor in regulations 12 to 14.
