Procurement terms, explained for bidders

Relevant terms covering UK and EU public procurement — from procedures and portals to scoring and strategy. Written by bid professionals, not lawyers.

Procurement procedures

Framework agreement

A long-term agreement between one or more buyers and one or more suppliers that establishes the terms for contracts awarded during its lifetime, typically lasting two to four years.

Dynamic purchasing system(DPS)

An electronic procurement system that remains open to new suppliers throughout its lifetime, allowing qualified providers to join at any point rather than only during an initial competition.

Open procedure

A single-stage procurement process where any interested supplier can submit a full tender response. There is no pre-qualification or shortlisting step — all compliant tenders are evaluated.

Restricted procedure

A two-stage procurement process where suppliers first complete a selection questionnaire to be shortlisted, and only shortlisted candidates are invited to submit a full tender.

Competitive dialogue

A procurement procedure where the buyer engages in structured conversations with shortlisted suppliers to develop solutions before inviting final tenders, used when the buyer cannot define the technical specification upfront.

Negotiated procedure without prior publication

A procurement route where the buyer negotiates directly with one or more suppliers without publishing a contract notice, permitted only in specific circumstances such as extreme urgency or where only one supplier can deliver.

Light touch regime(LTR)

A simplified procurement regime for certain social, health, education, and other specified services, with higher thresholds and more flexible procedural rules than the standard procurement regulations.

Mini-competition

A competition run among suppliers already appointed to a framework agreement or dynamic purchasing system to award a specific contract or call-off, using the terms established in the overarching agreement.

Call-off contract

An individual contract awarded under a framework agreement or dynamic purchasing system for a specific requirement, drawing on the pre-agreed terms of the overarching arrangement.
