An RFP asks for a proposed approach; a tender invites a bid. In UK public procurement, the published procedure sets the rules, whatever the pack is called.

Check these points before committing your team’s time.
what is the difference between a tender and an rfp
How much the buyer has already decided. An RFP is issued when the buyer knows the outcome it wants but not the method, and asks you to propose a solution — so what is being evaluated includes your approach. A tender is issued when the specification is already fixed, and asks you to bid on delivering it — so the bids are comparable and price carries more weight. In UK public procurement that remains a true description of intent, but it stops being what governs you: the procedure published in the tender notice sets your deadline, your entitlements and your right to challenge, whatever the document is called.
is rfp and tender the same
Not as concepts, and not as opposites either. In UK public work an RFP-titled pack is still run as one of the two competitive tendering procedures the Procurement Act 2023 allows — an open procedure or a competitive flexible procedure — so it is a tender process wearing a different word on the cover. Outside the public sector the distinction is real and useful, and nothing legal turns on it.
does "request for proposal" appear in the procurement act 2023?
No. A full-text search of the Act on legislation.gov.uk returns no results for "request for proposals", and also none for "invitation to tender", "request for quotation", "pre-qualification questionnaire", or the acronyms RFP, ITT, RFQ and PQQ. You can confirm the search itself works by running a control on a phrase that is in the Act — "competitive flexible procedure" returns one result. The Act’s vocabulary is tender notice, associated tender documents, competitive tendering procedure, conditions of participation and tender.
so where is "rfp" actually a legal term?
In the UNCITRAL Model Law on Public Procurement 2011, which lists ten procurement methods at Article 27 and makes three of them requests for proposals — without negotiation, with dialogue, and with consecutive negotiations — each with its own conditions for use and its own procedure article. It is also defined in US federal law at FAR 15.203, named as a selection method by the World Bank, and listed as a solicitation type in Canadian buyer guidance. It is a precise instrument in several jurisdictions. The UK is not one of them.
tender vs rfp — which one gets me better odds?
Neither label establishes the likelihood of winning. Read the published award criteria, participation conditions and your evidence of delivery. Incumbency or the document title is not a measured probability of success.
invitation to tender vs request for proposal
In British usage the ITT is the pack you respond to and the RFP is an imported term for a pack that asks you to design the solution. Neither phrase appears in the Procurement Act 2023 — the Act says "associated tender documents". In an open procedure the tender notice effectively is the invitation. Treat the two labels as interchangeable and read the procedure instead.
rfp vs rfq vs rfi
An RFI is not a competition at all — it is market research before one, and its statutory home in the UK is preliminary market engagement under section 16, with a notice duty at section 17. An RFQ asks for a price against a fixed specification, usually at low value. An RFP asks you to propose the method. Only the RFQ and RFP are procurement methods in the UNCITRAL sense, and none of the three acronyms appears in UK statute.
is there still a pqq or selection questionnaire?
Not as a standard document for above-threshold work. Cabinet Office guidance states that the Act does not prescribe how suppliers demonstrate they meet the conditions of participation, unlike the previous regulations which required the Single Procurement Document — in practice the Standard Selection Questionnaire. Core supplier information now sits on the central digital platform’s Supplier Information Service, and suitability is handled through conditions of participation under section 22. Industry pre-qualification questionnaires such as the Common Assessment Standard do survive in the works sector, and guidance expressly permits them.
does the procurement act 2023 apply in scotland?
Mostly not. The Act extends to Scotland, which is not the same as applying there — devolved Scottish authorities, including the Scottish Government, health boards, local authorities and universities, are on the excluded list at section 2(5)(a) and continue under the Procurement Reform (Scotland) Act 2014 and the Scottish regulations. The Act reaches them only through joint or cross-border arrangements. Wales is inside the Act with its own statutory instrument; Northern Ireland is inside above threshold but outside the below-threshold regime in Part 6.
what are the tender thresholds in 2026?
For 1 January 2026 to 31 December 2027, and stated including VAT: £135,018 for central government goods and services, £207,720 for sub-central, and £5,193,000 for works. Below those, a contract may still be a notifiable below-threshold contract under section 87(4) at £12,000 for central government authorities that are not devolved Welsh, or £30,000 otherwise. Those figures are no longer Contracts Finder thresholds — the notice goes to the central digital platform, and Contracts Finder is now a legacy store for procurements that began before 24 February 2025.
Is an RFI the same as preliminary market engagement?
Usually — UK law looks at what the exercise is for, not what it is called. Cabinet Office guidance says what makes something preliminary market engagement under section 16 “is the purpose and subject of the engagement and not the form”, so an RFI whose purpose is on the section 16(1) list is market engagement whatever it is called — and section 17 then requires a preliminary market engagement notice, or an explanation in the tender notice of why there was none.
RFP vs tender: which one lets the buyer negotiate?
Neither word decides it; the procedure does. An open procedure is a single stage, assessed on the tenders as submitted. A competitive flexible procedure may include negotiation, and its tender notice must describe the process, “including whether the procedure may include negotiation at any stage” (Procurement Regulations 2024, regulation 19(2)(c)(i)). If the notice does not provide for negotiation, an offer to negotiate is a problem, not an opportunity.
Where can you check the evidence?
Read the primary publication and the buyer’s current documents before acting.
