About Domestic Sub-Contract (DSC)

Introduced in 2005, the DSC emerged as a solution to the absence of a standardised contract form for dealings between main contractors and domestic sub-contractors or suppliers. This gap often left smaller firms grappling with contractual nuances, leading to inefficiencies and disputes.

Fast forward almost 20 years, and the DSC has evolved, reflecting the dynamic nature of construction practices and the growing emphasis on equitable treatment of all parties involved. This recent update to the DSC was spearheaded by a diverse group of industry experts comprising main contractors, subcontractors, lawyer and claim consultant, reflecting the changing industry environment, and addressing common modern challenges faced by all stakeholders.


What's new

Not just a simple update to meet new regulations from governing bodies, the updated version is a fine-tuning of clauses to better suit current industry needs. One of the most significant changes in the DSC 2.0 is the introduction of additional appendices, allowing parties to curate and tailor clauses relevant to their specific project type—be it building, civil, or M&E work. This bespoke, customisation-friendly approach ensures flexibility and applicability across various scopes of work.
