What is a tender?
A tender is a formal invitation from a buyer to suppliers, asking them to compete for a contract by submitting a written bid. In UK public procurement, the buyer is typically a public-sector body: a local council, NHS trust, government department, university, housing association or any organisation spending public money. Because public funds are involved, the process must be transparent, competitive and fair, which is why the UK has detailed procurement law governing exactly how tenders must be run.
When a public body needs goods, services or construction work above certain financial thresholds, it cannot simply phone a preferred supplier. It must publish a notice, run a structured competition and award on the basis of pre-declared criteria, giving every eligible supplier a fair chance and giving taxpayers confidence that public money is spent wisely.
Tender, quote, RFP, RFI, EOI: what is the difference?
Buyers use several instruments to engage the market, and the terminology can be confusing. The table below sets out the key distinctions.
| Instrument | Full name | Purpose | Typical binding nature |
|---|---|---|---|
| Tender / ITT | Invitation to Tender | Formal competitive bid process; suppliers submit a full priced proposal against a detailed specification | Supplier bid is binding; buyer commits on award |
| RFP | Request for Proposal | Buyer is open to different solutions; suppliers propose an approach as well as a price | Proposals may be subject to negotiation |
| RFI | Request for Information | Market-sounding exercise; buyer gathers intelligence before writing a specification | Non-binding on both sides |
| EOI | Expression of Interest | Pre-qualification step; suppliers indicate they wish to be considered and may submit basic capability information | Non-binding; a shortlist is then invited to tender |
| Quote | Request for Quotation | Informal or below-threshold price request, typically for lower-value or repeat purchases | Legally binding once accepted, but process is lighter |
In everyday use the word "tender" is often applied loosely to all of the above. On TenderSignal each notice type is clearly labelled so you can focus on what matches your business.
The typical tender timeline
UK public procurement follows a predictable sequence of stages. Timescales vary by procedure and complexity, but the shape is consistent.
1. Notice publication
The buyer publishes a contract notice on the Find a Tender service (FTS) or another approved platform. The notice sets out the scope, estimated value, CPV category codes, eligibility requirements and the deadline for expressions of interest or tender submissions. This is the moment TenderSignal picks up the opportunity and adds it to your personalised feed.
2. Clarification period
Once the tender documents are released, suppliers have a window to submit written questions. The buyer must respond to all substantive questions and publish the answers to every participant simultaneously. Asking good clarification questions is an important part of bid writing: it demonstrates engagement and helps you write a sharper response.
3. Submission
Suppliers prepare and submit their bids by the stated deadline, usually via a secure e-procurement portal. Late submissions are almost always rejected without exception. The bid pack typically runs to many pages and must address every question in the specification.
4. Evaluation
A panel of evaluators scores bids against the pre-declared criteria. Price and quality are weighted according to the proportions published in the notice. Under the Procurement Act 2023, buyers must award on the basis of the "most advantageous tender" rather than the old "most economically advantageous" language, though in practice the approach is similar.
5. Standstill period
Before the contract is signed, UK law requires a minimum standstill period of eight working days (ten days if notice is sent by post). During this window, unsuccessful suppliers can request a debrief and, if they believe the process was unlawful, apply to the courts for a suspension. This period is also known as the Alcatel pause.
6. Award and contract notice
Once standstill passes without a legal challenge, the contract is signed. The buyer must then publish a contract award notice within 30 days, showing the winning supplier and the awarded value. Award notices are also tracked on TenderSignal and are useful for understanding which suppliers are winning work in your sector.
Procurement procedures under the Procurement Act 2023
The Procurement Act 2023, which came into force in February 2025, replaced the Public Contracts Regulations 2015 with a simplified set of procedures. The main routes to market are as follows.
Open procedure
Any supplier can submit a full bid in response to the notice. There is no pre-qualification or shortlisting stage. Open procedure is the default for lower-complexity contracts and must allow a minimum of 25 days for bid preparation.
Competitive flexible procedure
This replaces the old restricted, competitive dialogue and innovation partnership procedures with a single flexible route. Buyers design a bespoke multi-stage process, for example shortlisting from an expression of interest, running dialogue, then inviting final tenders. Clear rules must be published at the outset.
Frameworks
A framework agreement is a pre-approved list of suppliers that have passed a qualification assessment. Individual contracts are then placed through a further competition or direct call-off among framework members. Frameworks can run for up to four years (eight years in exceptional circumstances). Getting onto a framework can be a reliable route to a pipeline of smaller contracts without competing from scratch each time.
Dynamic markets
The Procurement Act replaced the dynamic purchasing system with dynamic markets: open-ended approved lists that any qualifying supplier can join at any time. They suit fast-moving categories with a changing supply base, and unlike frameworks there is no closure date for new entrants.
What a tender document pack contains
When a buyer releases the full tender documents, you can expect to receive several components.
- Invitation to Tender (ITT): the top-level document setting out the rules of the competition, key dates, how to submit and how the process will be run.
- Specification or statement of requirements: the detailed description of what the buyer needs. This is the most important document for understanding scope, volumes, service levels and any mandatory standards.
- Pricing schedule: a structured template for your commercial response. Most buyers insist you use their template so responses can be compared like-for-like.
- Evaluation criteria and scoring methodology: a breakdown of how marks will be awarded. You should read this before anything else and structure your entire response around it.
- Conditions of contract: the draft terms you will be signing up to. Under the Procurement Act, buyers are encouraged to use standard contract terms where possible.
- Selection questionnaire (SQ): formerly the standard selection questionnaire (SSQ), this covers financial standing, insurance, relevant experience and technical capability. Some buyers run this as a separate pre-qualification gate; others fold it into the main ITT.
What happens after you submit
Submission is not the end of the process; it is the beginning of evaluation. Here is what to expect.
Award notification: you will receive a letter setting out whether you have been successful and, if not, your scores versus the winning bidder's scores. Under the Procurement Act, buyers must provide this information proactively.
Debrief: if you are unsuccessful, you are entitled to a detailed debrief explaining where your bid fell short. Always take one. Understanding your scores line by line is the fastest way to improve your win rate on future bids.
Standstill and legal challenge: if you believe the evaluation was conducted unlawfully, you can apply to the court for an automatic suspension of the award during the standstill period. This is rare in practice but is a meaningful protection for suppliers.
