The procurement glossary: 24 terms that decide whether you win

Public procurement has its own language, and most of it is never explained. This glossary covers the terms that change what a supplier actually does — the notice types, the buying vehicles, the assessment tests and the compliance rules. Every term here is one you will meet on a real UK contract. ER Monarch tracks 386 live renewals across 31 sectors from the same official notices these terms describe.

The documents and the process

Prior Information Notice (PIN)

An early signal that a buyer intends to procure something, published before the formal process starts. It is the earliest legitimate warning you get. A PIN is not a commitment — buyers sometimes publish one and never proceed — but it is the best opportunity you have to influence a specification before it hardens.

Contract Notice

The formal advert. This is the notice that opens the competition and sets out how to respond, the deadlines, and the evaluation criteria. If you are searching for “live opportunities”, this is the notice type you mean.

Contract Award Notice (CAN)

Published after the decision. It names the winning supplier, the value, and the contract dates. This is the most commercially valuable notice type for a supplier who is thinking ahead rather than reacting — because it tells you who holds the work and when it comes back.

Standstill period

A mandatory pause between telling bidders the award decision and actually signing the contract. It gives unsuccessful bidders a window to challenge the decision. Typically around ten days. If you lose, the standstill period is the only point at which a challenge is realistic — after it, the contract is signed and the route is gone.

VEAT (Voluntary Ex-Ante Transparency)

A notice a buyer publishes when they intend to award without competition, usually citing a legal ground. It is the buyer telling the market in advance. Read these seriously: every VEAT is a contract you may be able to contest, and a relationship you may be able to challenge. They are published publicly and most suppliers never look at them.

Alcatel period

The older name for the standstill period, from the court case that established it. You will still see it in older procurement documents.

The buying vehicles

Framework agreement

An agreement set up by a buyer or a purchasing consortium that suppliers can be appointed to, and which the buyer then uses to award contracts without running a full competition each time. Being on a framework is one of the highest-leverage positions in public sector supply, because it converts a one-off win into a multi-year pipeline.

Dynamic Purchasing System (DPS)

A framework with an open door. Suppliers can apply to join at any time during its life rather than only during the initial window. DPSs are common for services where the market changes quickly. If you missed a framework, a DPS is often still joinable.

Call-off

The individual order placed under a framework or DPS. The framework is the umbrella; the call-off is the actual work. This matters because a contract worth £5 million on paper may be split into call-offs that are individually much smaller — and because being on the framework is what makes you eligible for them.

Open procedure

One-stage competition: anyone can bid, and the winner is chosen from that single round.

Restricted procedure

Two stages: suppliers first submit a selection questionnaire (SQ) to pass a capability bar, then only shortlisted suppliers are invited to tender. Most of the work is in the questionnaire, not the tender.

Negotiated procedure

A process where the buyer can discuss terms with bidders. Restricted to specific legal grounds; not a general-purpose choice.

The assessment

Selection Questionnaire (SQ) / PAS 91

The standard pre-qualification questionnaire used across the public sector. It covers company details, financial standing, insurance, and past experience. It is reusable — keep a current version ready and you save days on every future bid.

Most Economically Advantageous Tender (MEAT)

The test used to award most contracts: not simply the lowest price, but the best combination of price and quality as set out in the award criteria. This is why a more expensive bid can win, and why the quality section deserves more of your effort than the pricing model.

Social value

The requirement to show additional benefit to the community beyond the contract itself — local employment, apprenticeships, environmental measures, support for small business. It now carries meaningful weight in most major UK procurements, and it is the section where unprepared bidders lose most cheaply.

Abnormally Low Tender (ALT)

A bid so far below the others that the buyer must investigate whether it is deliverable. If your price is genuinely much lower than the field, expect to be asked to justify it. Coming with that explanation prepared is the difference between winning and being excluded.

Compliance and transparency

Open Contracting Data Standard (OCDS)

The open data format in which UK procurement notices are published. It is what makes automated analysis possible — and what ER Monarch is built on. If you ever want to build your own tooling, OCDS is the schema you would read.

Open Government Licence (OGL)

The licence that permits reuse of most UK public sector information, including procurement notices. Reuse is allowed with attribution. This is the legal basis on which renewal intelligence can exist at all.

Procurement Act 2023

The UK’s post-Brexit procurement legislation, replacing the inherited EU regulations. It introduced changes to how pipelines are published, how frameworks are set up, and how buyers can exclude suppliers. If your knowledge of UK procurement predates it, some of that knowledge is now out of date.

Central Digital Platform

The single place where UK procurement notices are published and suppliers register. Designed to replace the fragmentation of separate portals over time — which, if it works, removes the single biggest administrative burden on small suppliers.

Why the vocabulary is worth learning

None of these terms are difficult. They are just unglamorous. The reason they matter is that a supplier who does not know what a VEAT or a call-off is will misjudge which opportunities are real — and will spend their bid effort in the wrong place.

Across the 386 live renewals ER Monarch tracks, you can see how much of the market sits under frameworks and call-offs rather than open adverts. That is exactly why renewal intelligence and tender alerts are different products: alerts tell you a door has opened; renewal intelligence tells you which door is about to.

Common questions

What is the standstill period in UK procurement?

A mandatory pause between notifying bidders of the award decision and signing the contract. It typically lasts around ten days and is the window in which an unsuccessful bidder can challenge the outcome.

What is a VEAT notice?

Voluntary Ex-Ante Transparency — a notice a buyer publishes when it intends to award a contract without competition, stating the legal ground. It signals an upcoming direct award before it happens.

What's the difference between a framework and a DPS?

A framework is closed once the initial competition ends; a Dynamic Purchasing System stays open so new suppliers can join at any time during its life.

What does MEAT stand for?

Most Economically Advantageous Tender — the price-and-quality test used to award most UK public contracts. It is why the cheapest bid does not automatically win.

What is OCDS?

The Open Contracting Data Standard — the open data format UK procurement notices are published in, and the basis for building automated renewal and spend analysis.
