Restricted Procedure

A two-stage procurement procedure where only pre-qualified suppliers invited after initial selection can submit tenders, reducing evaluation workload whilst maintaining competition.

How it works

The Restricted Procedure operates in two distinct stages under the Public Contracts Regulations 2015. First, contracting authorities publish a contract notice and selection questionnaire, inviting expressions of interest from potential suppliers. They then evaluate responses against predetermined selection criteria covering economic standing, technical capability, and professional competence.

Only suppliers who meet these criteria receive an invitation to tender in the second stage. The authority must invite a minimum number to ensure adequate competition - typically at least five where sufficient suitable candidates exist. Invited suppliers then submit detailed tenders addressing the technical specifications and award criteria.

When to use it

This procedure suits complex procurements where the authority expects many expressions of interest but wants to limit the number of detailed tenders evaluated. It works particularly well for construction projects, professional services, or technical contracts where thorough evaluation of supplier capability is essential before requesting full proposals.

The procedure reduces administrative burden compared to Open Procedure whilst maintaining competitive tension. It also allows authorities to engage with a manageable number of proven suppliers rather than potentially hundreds of respondents.

Time requirements

Minimum timescales apply: 30 days for selection stage responses (reducible to 15 days if prior information notice published), and 30 days for tender submissions (reducible to 10 days in urgent circumstances). These timescales can be extended where additional information is required.

Key considerations

Selection criteria must be proportionate and relevant to the contract. The same criteria apply to all candidates, and the authority cannot change requirements between stages. Clear communication of evaluation methodology and timescales is essential to maintain transparency and fairness throughout both stages.
