Common Terms

"A CALL" When a notice announcing a competition is advertised publically.

"AGGREGATION" Where tranches of services, works, and supplies procurements, lots or frameworks are grouped together into larger single contracts, lots, procurements or frameworks.

"CPV CODES" CPV (ref. legal definitions above) codes have been developed by the European Union specifically for public procurement. Their main purpose is to help procurement personnel to classify their contract notices consistently and correctly and to help suppliers find the notices which are of interest to them, by using a standardised vocabulary.

The CPV codes consist of a main vocabulary for defining the subject of a contract, and a supplementary vocabulary for adding further qualitative information. The main vocabulary is based on a tree structure comprising codes of up to 9 digits (an 8 digit code plus a check digit) associated with a wording that describes the type of supplies, works or services forming the subject of the contract.

If a contracting authority inserts the incorrect CPV code in a notice, suppliers are unlikely to be able to find it directly according to search criteria based on their own trade.

"CONTRACT AWARD NOTICES" (CAN) A notice for services, works or supplies procurements that is issued publically, announcing the results of the tender procedure with the names of those who have successfully won awards. These notices are issued in the form and manner specified under the regulations after the required standstill period.

"e-CERTIS" a digital information system providing a reference tool that helps clients identify the different certificates and attestations frequently requested in procurement procedure to facilitate cross border trading. All language versions of the European Single Procurement Document (ESPD) will become available on e-Certis.

"DESIGN QUALITY" There is no set definition for what constitutes good, quality design. However, for a discussion of the topic please see RIBA's 'Good Design it all adds up'

"EU" Means the European Union.

"EU PROCEDURES" or "EU PROCESS" means a procurement process which requires that a notice is advertised in the TED supplement to OJEU, in accordance with procedures required under Directive 2014/24/EU and the Public Contract Regulations 2015.

"EU THRESHOLDS" The EU thresholds in public procurement regulations apply to higher value works and vary depending on the type of contracting authority, whether it's a procurement for works, services or supplies and the procurements estimated value. When procurements have a value not less than the relevant amounts and are not excluded by the regulations scope the procurement must comply with the more onerous requirements of the regulations and be advertised on both contracts finder and the European portal. The threshold amounts are specified in Regulation 5 and in Directive2014/24/EU Art.4.


These fundamental principles will apply to all contracts that a public body enters into, regardless of whether the full EU procurement rules apply. The EU Treaty principles include the following:

For example, a contracting authority should not require technical capability, professional status or economic strength that is far beyond that needed to deliver a contract. The public body must accept technical specifications and qualifications if they are equivalent to the national specifications and qualifications the public body has specified.

These principles underpin all procurement law and contracting authorities should always consider them throughout their procurements.

"EXPRESSION OF INTEREST (EOI)" An expression of interest refers to any bidders submission in response to a call for competition. Such calls maybe for open or restricted procedures, in single or multiple stages or design contests where the response is assessed anonymously. Prequalification questionnaires (PQQs) are distinct question sets issued by contracting authorities in accordance with Part 2 of the regulations. Question sets

A bidder submitting an expression of interest might be required to do so by completing a PQQ, although particularly in the design contest procedures this may not apply.

"FRAMEWORK" (ref also section 2 - legal definition of a 'framework agreement') Means an agreement between one or more contracting authorities and one or more economic operators, the purpose of which is to establish the terms governing contracts to be awarded over a given period (typically 4 years).

"LIGHT THRESHOLDS" or "LOW VALUE THRESHOLDS" Where Public Contract Regulations 2015 Part 4 apply to low value procurements the light regime regulates for transparency and precludes use of PQQs. The low-value rules apply to central government procurements with a contract value above 10,000, and to procurement by other authorities above 25,000 (but in only where the value of the contract is below the relevant EU thresholds)

"LOTS" Contracts let within a single procurement. Used when a procurement notice provides for divisions within a single procurement allowing for the award of discrete individual contracts.

The distinction between the different lots within a single procurement may vary according to what type or mix of services, works or supply is sought and typically on the basis of value, scale, typology, location context and the numbers of operatives that might be required to undertake the outputs.

Lots maybe used with any of the standard procedures and design contests but the largest numbers of lots are most frequently found in defining separate contracts in frameworks eg architectural services, engineering, MEP, project management, construction services, with sub-division according to the award values, typology, level of risk sought, geographic regions and whether for new or refurbishment. Design services and construction works are generally best let separately.

"NUTS CODES" (The Nomenclature of Territorial Units for Statistics). A geographical code provided within notices to define the location of a procurement with the EU; and providing valuable national, regional and sub-regional economic data.

If a contracting authority inserts the incorrect NUTS code in a notice, suppliers are unlikely to be able to find it directly according to search criteria based on their own area of economic activity. Local Administrative Units (LAUs) allow a greater degree of local classification than the NUTS geographic codes. The coding system is compatible with NUTS.

Contracting authorities preparing a procurement notice should insert NUTS and LAU codes consistently in all notices relating to a single procurement according to the location of the procurement contract (and not where the procurement might be prepared and/or issued from).

"OJEU" or "OFFICIAL JOURNAL OF THE EUROPEAN UNION" A multi-language daily publication (Tues-Sat), The Official Journal of the European Union (OJ) is the official compendium of EU legislation (L series) and other official documents of the EU institutions, bodies and agencies (C series and its supplements). Procurements are published electronically within a supplement called TED (tenders electronic daily).

Colloquially however OJEU used within UK procurement terminology has come to refer to any required above threshold procedure (an 'OJEU Procedure') or the publication of a procedure on TED ('OJEU Notice').


PINs typically allow clients to forewarn the market of their procurement intentions within the next 12 months to allow bidders to prepare to bid for the contract before the procurement process officially begins. Under the Public Contract Regulations 2015 regulation 48 they may also be used as a call for competition for restricted procedures, and competitive procedures by negotiation making it possible to accelerate clients' selection processes by 30 days or more.

For works contracts, a PIN must be issued as soon as possible after the planned work(s) is approved.

Contracting authorities and their suppliers should be alert to competitions being called for within Prior Information Notices (PIN) for restricted procedures, and competitive procedures by negotiation, and given the timescale which can be applied clients should endeavour by all other pre marketing engagements possible to forewarn suppliers to ensure they attract the most competitive bids.

"PQQ" or "PRE QUALIFICATION QUESTIONNAIRE" (may also known as a Supplier Questionnaire). Usually issued to bidders wishing to respond to a call for competition for works, goods or services or to join a 'Framework'. PQQs are used under The Public Contract Regulations Part 2 Chapter 2 in procedures for the submission of pre tendering information submitted in response and prior to a tender. PAS91: 2013 (Publicly available specification) provides one standardised template question set that maybe asked in whole or parts by buyers of their suppliers that has been developed for use in the construction industry.

"RESTRICTED PROCEDURES" Means those procedures in which any economic operator may request to participate and whereby only those invited forward by the contracting authority on the basis of compliance and assessment of a PQQ response or in the case of Design Contest by other restrictions, may submit a tender.

"THINNING" techniques used in the drafting of questionnaires, technical specifications and for selection procedures to reduce the numbers of tenders shortlisted for the tender and contract award. Procurements should be constructed on real contextual qualitative criteria relating to the outputs sought taking full regard of Regulation 42 (10) which states that all such technical specifications "shall afford equal access of economic operators to the procurement procedure and shall not have the effect of creating unjustified obstacles to the opening up of public procurement to competition".

"TIER 2 SUPPLIER" The tier 1 supplier is the main contractor, tier 2 suppliers are sub-contractors and tier 3 suppliers are sub-contracted to tier 2s. For example, in Design and Build Contracts, an architect is employed by the main contractor and becomes a 'tier 2 contractor' to the client.


Means the value as specified by the Public Contract Regulations 2015 above or below which different regulatory regimes apply. Under the Public Contract Regulations 2015 there are two threshold levels. The light thresholds are for procurements of low value where Part 4 of the Public Contract Regulations apply and the EU thresholds for higher values where Part 2 of the Regulations apply.

The threshold values within the EU Procurement Directives are reviewed bi-annually and maybe amended accordingly from time to time.
