About CNJ Consultants

Independent cost consultants supporting contractors with accurate pricing, tender clarity, and commercial control across live projects.

Who we are

Commercial Cost Support for Contractors

CNJ works directly with contractors to provide independent cost advice at every commercial stage of a project. From early pricing and tender submissions through to live cost control, we support contractors who want certainty, speed, and defensible numbers.

We understand the pressures of competitive tendering, fixed-price risk, and client scrutiny. Our role is to strengthen your commercial position, reduce exposure, and help you deliver projects with clarity and confidence.
