Registration Criteria

The Register contains two lists: the list of Main Contractors and the list of Specialist Contractors.

A company applies either as a main contractor or as a specialist contractor. If a company wishes to appear on both lists, two applications are required (although reference to documentation provided in another application is accepted, separate application form and project reference forms are necessary).

Main Contractors are capable of taking on any type of heritage work. They must demonstrate experience across the different categories. Main Contractors will generally use Specialist Contractors for the execution of the work.

Specialist Contractors are capable of executing projects in the category in which they are registered. If they are registered in the sub category ‘general’, they can undertake any project, which falls within the category.

The Register uses general and heritage contracting specific requirements.

Both Main Contractors and Specialist Contractors must satisfy all general requirements.
