The A–Z of UK Bid and Procurement Terminology A practical glossary for businesses bidding for UK public and private sector contracts Bid terminology should make opportunities easier to understand—not create another barrier to winning work. Tender documents can contain a confusing mixture of procurement terminology, legal language, commercial expressions, construction-specific terms and bid-management shorthand. The position has become more complicated since the introduction of the Procurement Act 2023, because new terminology now operates alongside expressions inherited from older procurement regulations. This glossary explains the terms, acronyms and phrases most commonly encountered when bidding for contracts in the United Kingdom. It covers public procurement, commercial bidding, bid management, evaluation, frameworks, construction tenders and contract award. A note on the UK procurement market The Procurement Act 2023 came into force on 24 February 2025 . It applies principally to contracting authorities in England, Wales and Northern Ireland, as well as authorities exercising reserved functions in Scotland. Devolved Scottish authorities continue to operate under separate Scottish procurement legislation. Procurements commenced before 24 February 2025 generally remain subject to the previous legislation. Suppliers may therefore continue to encounter legacy terms such as PQQ, MEAT, restricted procedure, competitive dialogue, DPS, PIN, contract notice and further competition for several years. The bid-management terms used below reflect established UK industry practice and recognised proposal-development methods, including opportunity qualification, compliance planning and staged reviews. It is an ever-evolving list.... A Abnormally Low Tender A tender containing a price or cost that appears unusually low in relation to the requirement. A contracting authority may investigate whether the price is sustainable, accurate and compliant before deciding whether the tender should be disregarded. Acceptance The buyer’s formal agreement to an offer. In contractual terms, acceptance may create a binding agreement where the other required elements of contract formation are present. Addendum A formal amendment or addition to the tender documents issued by the buyer. An addendum may change the specification, submission requirements, timetable, pricing documents or contractual terms. Alternative Bid See Variant Bid . Approved Supplier List A list of suppliers that a buyer has assessed and approved for particular categories of work. Being included does not always guarantee opportunities or contract awards. Assessment Methodology The rules explaining how the buyer will assess tenders. It may include scoring scales, weightings, pass/fail requirements, moderation arrangements and the treatment of price and quality. Under the Procurement Act 2023, the methodology must be set out in the tender documentation and applied consistently. Assessment Summary The information provided to a supplier explaining the assessment of its tender and, where relevant, the successful tender. Assessment summaries perform a similar function to the standstill or award decision letters used under previous legislation, although the statutory content and process are different. Assessed Tender A tender that has progressed to assessment against the published award criteria. The term is relevant to the requirement to issue assessment summaries under the Procurement Act 2023. Authority A commonly used abbreviation for the organisation procuring the contract. In public procurement, the statutory expression is usually contracting authority . Authorised Signatory A person with authority to sign a tender declaration, form of tender, contract or other legally significant document on behalf of the bidding organisation. Award Criteria The criteria used to identify the most advantageous tender. Criteria must relate to the subject matter of the contract, be sufficiently clear and measurable, and be accompanied by an assessment methodology. Award Decision The buyer’s decision identifying the supplier or suppliers it intends to appoint, subject to any remaining approvals, notifications and standstill requirements. Award with Competition A competitive process used to award a contract under a framework. It is the Procurement Act 2023 expression broadly replacing the legacy term further competition . Award without Competition The award of a contract without seeking competing tenders. This may be permitted under a framework or where a lawful direct award justification applies. B BAFO – Best and Final Offer A final revised offer requested after clarification, dialogue or negotiation. Suppliers may be asked to improve their technical solution, commercial offer or contractual position. Benchmarking Comparing prices, performance, service levels, resources or proposed outcomes against previous contracts, market data, competitors or recognised standards. Benefit The positive result the buyer, service user or wider community will receive from a feature of the proposed solution. Strong tender responses explain the benefit rather than merely describing what the supplier will do. Bid A supplier’s formal offer to deliver specified goods, works or services. The term may refer to the complete submission or to the process of pursuing an opportunity. Bid Bond A financial guarantee protecting the buyer if a bidder withdraws, refuses to enter into the contract or fails to provide required security. Bid bonds are more common in major construction, infrastructure and international procurements. Bid Budget The internal budget allocated to pursuing an opportunity, including staff time, consultancy, design, legal review, estimating, travel and production costs. Bid Compliance The extent to which a submission meets all instructions, conditions, requirements and deadlines. Bid Director The senior person providing strategic oversight, executive support and internal authority for a major bid. Bid Library A controlled collection of approved company information, evidence, policies, case studies, CVs, accreditations, statistics and reusable tender content. Bid Manager The person responsible for coordinating the bid process, programme, contributors, compliance, reviews, approvals and submission. Bid/No-Bid Decision A structured decision on whether an opportunity should be pursued. Typical considerations include strategic fit, eligibility, customer knowledge, competition, capacity, profitability, risk, evidence and probability of winning. Bid Plan The document or schedule showing how the bid will be developed, reviewed, approved and submitted. Bid Strategy The overarching approach to winning an opportunity, including positioning, differentiators, solution priorities, commercial approach, risks and key messages. Bid Team The people contributing to the submission. This may include a bid manager, writer, estimator, commercial lead, operational lead, technical specialists, designers, legal advisers and senior reviewers. Bid Validity Period The period during which the supplier must keep its offer open and cannot normally change or withdraw its price without the buyer’s agreement. Bidder An organisation participating in a competitive procurement. Procurement Act documentation may instead use the broader term supplier . Bill of Quantities – BoQ or BQ A structured list of work items, descriptions, units and quantities used to obtain comparable construction prices. Blue Team Review An early-stage review of the opportunity, customer, strategy and proposed solution. Terminology varies between organisations, but a Blue Team usually takes place before substantial drafting. C Call-Off Contract A contract awarded under a framework. The call-off creates the legally binding requirement for the specific goods, services or works being purchased. Call-Off Schedule A contractual schedule setting out terms applying to contracts awarded under a framework. Capture Management The structured process of positioning an organisation to win an opportunity before the formal tender is released. Capture Plan A live document covering the customer, requirement, stakeholders, competitors, partners, solution, evidence, risks, commercial position and actions needed to improve the probability of winning. Carbon Reduction Plan – CRP A document setting out an organisation’s greenhouse-gas emissions and commitments or measures for achieving carbon reduction. Some government procurements require suppliers to provide a compliant CRP. Central Digital Platform The government’s digital procurement infrastructure under the Procurement Act 2023. It incorporates an enhanced Find a Tender service for notices and the Supplier Information Service for reusable supplier information. Challenge A formal legal challenge or less formal complaint concerning the conduct or outcome of a procurement.

Clarifications should not normally be used to make an impermissible material change to a tender. Clarification Deadline The final date by which bidders may submit questions through the procurement portal. Clarification Log A record of questions submitted, responses received, changes issued and resulting actions for the bid team. Closed Framework A framework under the Procurement Act 2023 that does not admit new suppliers after it has been established. It is the more traditional form of framework arrangement.

It creates a more consistent assessment of areas such as identity, financial standing, health and safety, environmental management, quality, information security, building safety and corporate responsibility. Commercial Agreement A collective expression that may refer to a framework, open framework, closed framework or dynamic market. Its exact meaning should be checked in the relevant procurement documents. Commercially Sensitive Information Information whose disclosure could damage a supplier’s legitimate commercial interests, such as pricing methodology, intellectual property or confidential operating processes. Marking information as sensitive does not automatically prevent disclosure under information-access legislation. Compliance Matrix A structured register identifying every tender instruction, question, requirement, attachment, declaration, deadline and submission condition. It helps the bid team demonstrate that nothing has been omitted. Competitive Dialogue – Legacy Term A procedure under the Public Contracts Regulations 2015 that allowed buyers to discuss potential solutions with shortlisted bidders before calling for final tenders. It is not a separate procedure under the Procurement Act 2023, although similar dialogue may be incorporated into a competitive flexible procedure. Competitive Flexible Procedure – CFP A competitive procedure designed by the contracting authority to suit the requirement. It may include shortlisting, negotiation, dialogue, demonstrations, site visits, presentations or successive tender stages, provided the process complies with the Act and the published tender notice and documents. Competitive Procedure with Negotiation – Legacy Term A procedure under the previous regulations involving shortlisting and negotiation. It is not retained as a separately named procedure under the Procurement Act 2023. Competitive Tendering Procedure Under the Procurement Act 2023, either an open procedure or a competitive flexible procedure . Both commence through the publication of a tender notice. Conditions of Participation Proportionate requirements concerning a supplier’s legal and financial capacity or technical ability to perform the contract. They determine whether a supplier is capable of participating or being awarded the contract; they are distinct from the criteria used to assess the quality of the tendered solution. Conflict Assessment The contracting authority’s assessment of actual, potential and perceived conflicts of interest affecting a procurement. Conflict of Interest A situation in which a person’s financial, professional, personal or other interests could improperly influence—or appear to influence—the procurement. Contracting authorities must take reasonable steps to prevent conflicts from creating an unfair advantage or disadvantage. Consortium Two or more organisations bidding together without necessarily forming a separate incorporated entity. Contract Award Notice A notice published before the contracting authority enters into a public contract, identifying the intended award and other prescribed information. Where a standstill period is required, the notice forms part of the pre-contract award process. Contract Change Notice A notice published in connection with certain modifications to an existing public contract. Publication requirements and exemptions depend on the nature and value of the modification. Contract Details Notice A post-award notice confirming that the contracting authority has entered into the contract. Depending on the contract, it may also be accompanied by publication of the contract and specified KPIs. Contract Documents The complete set of documents forming the legal agreement.

The authority must consider whether the relevant circumstances are continuing or likely to recur. Down-Select The process of reducing the number of bidders progressing to the next stage of a procurement. Due Diligence Checks undertaken to verify a bidder’s information, financial standing, ownership, capacity, compliance, references, pricing or proposed delivery arrangements. Dynamic Market A list of suppliers that meet stated membership conditions and may compete for future contracts. Unlike a closed framework, a dynamic market generally remains open to new qualifying suppliers. It replaces the Dynamic Purchasing System for new procurements under the Procurement Act 2023. Dynamic Market Notice A notice used when a dynamic market is established, changed or terminated, or when information about the market must otherwise be published. DPS – Dynamic Purchasing System – Legacy Term An electronic purchasing arrangement that remained open to new qualifying suppliers throughout its duration. New Procurement Act arrangements use dynamic markets , but DPSs established under the previous regulations may remain operational during the transition period. E Early Contractor Involvement – ECI The appointment or involvement of a contractor during the design or planning stage so that buildability, risk, cost, logistics and programme advice can inform the final solution.

Output Specification A specification describing the required results or performance rather than prescribing exactly how the supplier must deliver them. P PAS 91 – Legacy Construction Term A standardised construction prequalification questionnaire formerly used widely across the UK. It has largely been superseded by the Common Assessment Standard, although PAS 91 terminology may remain in older documents and processes. Payment Compliance Notice A notice reporting specified information about a contracting authority’s payment performance under public contracts.

PPN – Procurement Policy Note A policy instruction or guidance note issued to specified public bodies. UK Government PPNs, Welsh WPPNs, Northern Ireland procurement policy publications and Scottish SPPNs have different scopes. PQQ – Pre-Qualification Questionnaire – Legacy and Informal Term A questionnaire used to assess a supplier’s eligibility, financial standing, technical capacity and experience before inviting it to tender. Under the Procurement Act 2023, supplier information, exclusions and conditions of participation are addressed through the central digital platform and procurement-specific information rather than the former standard PQQ model. Preferred Bidder The bidder selected as the intended supplier before all final contractual or governance steps have been completed. The expression does not always constitute a formal contract award. Preliminary Market Engagement – PME Engagement with suppliers or other stakeholders before publication of the tender notice. It may help the buyer understand market capacity, develop the requirement, test commercial assumptions and design an accessible competition. Preliminary Market Engagement Notice A notice informing the market about planned preliminary market engagement and how suppliers may participate.

Procurement Specific Questionnaire – PSQ A questionnaire used under the Procurement Act regime to collect procurement-specific information, including information relating to conditions of participation, exclusions and debarment. It performs a role broadly comparable to parts of the previous Selection Questionnaire. Procurement Termination Notice A notice stating that a contracting authority has decided not to proceed with a procurement after it has been formally commenced. It should not be confused with a contract termination notice , which concerns an existing contract. Programme The planned sequence and timing of activities, dependencies, milestones, approvals and completion dates. Proposal A supplier’s explanation of its recommended solution and commercial offer. In UK usage, “proposal”, “bid” and “tender” are sometimes used interchangeably, although the precise meaning depends on the buyer and context. Provisional Sum An allowance within a construction price for work that cannot be fully defined or valued when the tender is submitted. Public Benefit The wider benefit that may be achieved through procurement beyond the immediate contractual requirement, including social, economic or environmental outcomes.

Remedies can include orders affecting the procurement process, contract-related remedies and damages, depending on the circumstances and timing of the challenge. Request for Information – RFI A request used to obtain market, technical, capability or pricing information. An RFI does not usually constitute a formal invitation to tender. Request for Proposal – RFP A request for suppliers to submit a detailed proposed solution and commercial offer. The expression is common in private-sector and international bidding. Request for Quotation – RFQ A request focused primarily on obtaining a price for a clearly defined requirement, although supporting quality information may also be required.

Residual Risk The risk remaining after planned controls or mitigations have been applied. Response Plan A structured plan for an individual tender question, identifying the evaluator’s requirements, key messages, evidence, structure, contributors and word allocation. Restricted Procedure – Legacy Term A two-stage procedure under the previous regulations. Suppliers first completed a selection stage, after which shortlisted organisations were invited to tender. It is not a separately named procedure under the Procurement Act 2023. Risk Register A controlled record of risks, causes, consequences, probability, impact, controls, owners and further actions. Risk Transfer The allocation of responsibility for a risk from one contractual party to another. Suppliers should assess whether transferred risks are controllable, insurable and properly priced. S Schedule of Rates – SoR A list of agreed rates for defined work items, labour, materials, plant or services. Actual payment may depend on the quantity of work instructed or completed. Scoring Matrix A table showing the relationship between evaluator judgements and numerical scores.

Under the Procurement Act 2023, the comparable statutory concept is generally addressed through conditions of participation . Selection Questionnaire – SQ – Legacy Regime The standard questionnaire used under the PCR 2015 regime to gather supplier information and self-declarations about exclusion grounds, financial standing and technical capability. For above-threshold Procurement Act procurements, reusable supplier information is instead provided through the central digital platform, supplemented by procurement-specific questions. Self-Cleaning Evidence and corrective action demonstrating that circumstances giving rise to an exclusion ground are no longer continuing or are unlikely to recur. Measures may include organisational change, compensation, investigation, cooperation and improved compliance controls. Sell2Wales The Welsh Government’s procurement portal and information service for public-sector opportunities in Wales.

Understanding old and new terminology For the foreseeable future, UK bidders will need to understand both Procurement Act terminology and the language used under the previous regulations. The applicable terminology should always be determined by checking: when the procurement was commenced; which UK jurisdiction and contracting authority are involved; whether the requirement is above or below the relevant threshold; whether the contract is covered, exempted, light-touch, utilities, defence or concession-related; whether the opportunity is being procured through a legacy framework or DPS; and the specific instructions, definitions and conditions contained in the tender documents.
