Restricted Procedure

In a restricted procedure, the procurement is split into two distinct stages: a selection stage (invitation to express interest / submit a PQQ or ESPD) and an award stage (invitation to tender sent only to those who pass selection). The contracting authority sets minimum shortlist sizes — typically at least five suppliers must be invited to tender — and selection criteria must be proportionate and pre-disclosed.

Restricted procedures are appropriate when the contract is complex enough that evaluating full tenders from an unlimited pool would be disproportionately burdensome, or when the market is known to contain many unqualified suppliers. They are common in defence, large IT, and specialist professional services. The EU permits restricted procedures above threshold on a routine basis; below threshold, many authorities run their own restricted quote procedures.

For vendors, the restricted procedure creates a two-gate bidding process. Passing the selection stage consumes time and resources, but being shortlisted provides a meaningful competitive advantage — the pool typically narrows to three to seven firms. Firms that invest in PQQ/SQ excellence (strong financial health, reference projects closely matched to the requirement, certified key staff) convert shortlisting opportunities into ITT invitations at higher rates. Maintaining a library of pre-written PQQ responses is standard practice for active public-sector vendors.
