Also known as: Sub-contracting

Last reviewed April 2026

The practice of a main contractor engaging third parties to deliver part of a public contract, regulated under Regulation 71 of S.I. 284/2016.

Regulation 71 of S.I. 284/2016 lets contracting authorities require bidders to disclose proposed subcontractors at tender stage and during contract execution. Authorities can verify subcontractors against exclusion grounds and selection criteria, and can require their replacement where they fail those checks. On Irish public works, subcontractors must comply with the Construction Industry Register Ireland (CIRI) requirements and Relevant Contracts Tax (RCT) rules. The main contractor remains liable for performance to the authority.
