How the UK tendering process works (2026 update)

2026-07-14 · 14 min read

This guide assumes you already know what a tender is. If you're starting from scratch, read "What is a tender? A plain-English guide for UK businesses" first.

The tendering process in brief

Most guides to the UK tendering process describe it as a clean sequence of stages. In practice it rarely feels that clean — timelines slip, stages overlap, and buyers don't always follow the textbook. But understanding the intended process gives you the framework to navigate whatever variation you encounter.

The process typically runs across eight stages. The first two — market engagement and the prior information notice — are optional and often skipped on smaller contracts. The remaining six are the core procurement sequence that most suppliers will recognise.

Stage 1 — Market engagement

Market engagement is the stage most guides leave out. On larger or more complex procurements, buyers will often consult the market before writing the specification — talking to potential suppliers to understand what's achievable, what it's likely to cost, and whether their requirements are realistic.

From a supplier's perspective, market engagement is worth engaging with when you get the chance. It gives you earlier sight of what's coming, a chance to understand the buyer's priorities before they're locked into a specification, and occasionally an opportunity to influence the shape of the requirement. Under the Procurement Act 2023, buyers must take steps to ensure that any supplier who participates in market engagement isn't advantaged or disadvantaged in the subsequent tender — so engaging doesn't give you a leg up, but it does give you a head start on understanding the opportunity.

The significant caveat: market engagement has no fixed duration and no published deadline. Buyers complete it when they're ready, which can be weeks or months after the initial engagement. A market engagement exercise completed in May might not result in a contract notice until September or October — and suppliers who've pencilled a June start into their pipeline will be waiting. If you're tracking an opportunity that has gone through market engagement and gone quiet, it hasn't disappeared. It's in the gap between engagement and publication, where buyers are refining the specification, getting legal sign-off, and clearing internal approvals.

Stage 2 — Prior information notice

A Prior Information Notice (PIN) is an optional early signal that a contract is coming. Buyers publish PINs to give the market advance warning — typically when a significant contract is approaching or when they want to build a pool of interested suppliers ahead of a formal process.

PINs are worth monitoring if you're targeting specific buyers or sectors. They don't commit the buyer to a timeline, but they give you earlier sight than waiting for the contract notice. Under the Procurement Act 2023, buyers can also use a PIN as a call for competition in certain circumstances, which collapses the PIN and contract notice into a single step.

In practice, many contracts — particularly below threshold — are published with no PIN at all. Don't rely on PIN monitoring as your primary pipeline tool. It's useful supplementary intelligence, not a complete early-warning system.

Stage 3 — Contract notice published

The contract notice is the formal advertisement that a tender is open. In the UK, contract notices are published on:

• Find a Tender Service (FTS) — for contracts above the relevant threshold (currently £139,688 including VAT for most central government goods and services; higher thresholds apply for other categories).
• Contracts Finder — for contracts above £12,000 with central government and above £30,000 with other public bodies.
• Sector-specific portals — NHS Supply Chain, local authority procurement portals, and others often run in parallel with the above.

The contract notice sets out the scope, estimated value, deadline for expressions of interest or submissions, and the CPV codes that classify the contract type. It also signals whether the process will involve a selection stage or go straight to ITT.

Finding the right opportunities before the notice is published — through pipeline intelligence, buyer relationship-building, and portal monitoring — is a meaningful competitive advantage. Most businesses wait for the notice. The best ones are already prepared when it lands.

Stage 4 — Selection questionnaire

Not every tender includes a selection stage, but most contracts above threshold do. The Selection Questionnaire (SQ) replaced the old Pre-Qualification Questionnaire (PQQ) under the Procurement Act 2023. The intent was standardisation — a consistent set of questions that suppliers answer once rather than completing bespoke PQQs for every buyer.

In practice the transition is still bedding in. Some buyers continue to use their own selection criteria alongside or instead of the standard SQ, and the level of consistency varies across sectors and contracting authorities.

The SQ covers:

• Legal and regulatory standing — grounds for mandatory and discretionary exclusion (convictions, tax compliance, professional conduct).
• Economic and financial standing — turnover thresholds, insurance requirements, financial ratios.
• Technical and professional ability — relevant experience, accreditations, key personnel.

The SQ is pass/fail. Responses are evaluated against minimum standards; those who pass proceed to the ITT stage. The SQ is not where contracts are won — but it is where they can be lost, often on administrative grounds that have nothing to do with your ability to deliver.

Common SQ failures: insufficient turnover relative to contract value, expired or inadequate insurance cover, case studies that don't match the required format or contract type, and missing supporting documents. Check the requirements against your current position before you invest time in the ITT.

Stage 5 — Invitation to tender

The ITT is the main event. Shortlisted suppliers receive the full tender documents and are invited to submit a complete response by the stated deadline.

The ITT pack typically contains:

• The specification — what the buyer wants delivered, in detail.
• Evaluation criteria and weightings — how responses will be scored.
• Questions and word counts — the sections you'll write.
• Pricing schedules — how the buyer wants costs presented.
• Draft contract terms — what you'll be agreeing to if you win.
• Submission instructions — format, portal, deadline.

The time between ITT issue and submission deadline is the window you have to prepare your response. On complex contracts this might be eight to twelve weeks. On simpler ones it can be as short as two weeks. Whatever the window, most of the strategic work — understanding the buyer, planning your win themes, mapping your evidence — should happen in the first few days, not the last.

Clarification questions are usually permitted during the ITT period, submitted through the portal and answered (anonymously, to all bidders) by the buyer. Use them. If a requirement is ambiguous or a scoring criterion is unclear, ask — the answer goes to everyone, but the question shows you've read the documents carefully, and the answer might change your approach.

Stage 6 — Submission

Submissions are made through the buyer's procurement portal by the stated deadline. Late submissions are almost always rejected without exception. Portal issues, technical problems, and last-minute file size errors are not accepted as mitigating circumstances.

Practical submission discipline:

• Register on the portal as soon as you receive the ITT — don't leave it until the day before.
• Upload documents progressively rather than in a single last-minute batch.
• Check file format and naming requirements — buyers specify these and some portals reject non-compliant uploads.
• Aim to submit at least 24 hours before the deadline.
• Keep a complete copy of everything you submitted, including version-controlled drafts.

Clarification requests can continue after submission in some processes — the buyer may ask questions about your response during evaluation. These are not an opportunity to revise your bid; they're clarifications of what you already submitted.

Stage 7 — Evaluation

Evaluation happens behind closed doors and takes longer than most suppliers expect. On a straightforward contract, evaluation might take four to six weeks. On a complex multi-lot procurement it can run to several months.

During evaluation, buyers score responses against the published criteria and weightings. Under the Procurement Act 2023's Most Advantageous Tender (MAT) framework, buyers score against two headline dimensions: quality and price. The split between them is set by the buyer and published in the ITT — common splits are 60/40, 70/30, or 80/20 in favour of quality.

Within the quality dimension, buyers typically break the score down across several criteria, each carrying its own weighting. The exact criteria vary by contract type and sector, but the most common include:

• Technical capability and methodology — how you intend to deliver the contract, your approach, and evidence that you've done comparable work before.
• Understanding of the requirement — demonstrating that you've read and genuinely understood what the buyer needs, not just what the specification says on the surface.
• Mobilisation and implementation — how you'll transition into the contract, manage the start-up period, and hit the ground without disrupting service.
• Staffing and management — the team that will deliver, their experience, and how the contract will be managed day to day.
• Risk management — how you've identified the key risks and what you'll do about them.
• Social value — the broader economic, social, and environmental benefits you'll deliver alongside the contract itself.

Social value is scored as one criterion within the quality assessment, not separately alongside it. Under PPN 002, central government contracts above threshold must apply a minimum 10% weighting to social value. Local authorities and NHS bodies are encouraged to do the same, and many do. In practice, social value questions attract 10–20% of the total quality marks depending on the buyer and contract type — enough to swing the outcome, and more than enough to lose on if your response is generic.

Each quality criterion carries its own sub-weighting, published in the ITT, and that weighting should guide where you spend your planning and evidence-gathering time. A technical methodology question worth 30% of the quality marks typically demands more research, more evidence, and more iteration than a social value question worth 10%. But low weighting is never a reason to submit a generic answer. Social value questions are exactly where evaluators expect to see specific, measurable commitments — and exactly where most responses default to vague pledges about supporting local employment. A weak answer on a 10% question still costs you those marks. The weighting tells you how much time to budget; it doesn't excuse the quality of what you write.

Evaluation panels typically involve multiple evaluators scoring independently, with moderation where scores diverge. Some buyers also conduct presentations or site visits as part of evaluation, particularly on larger contracts — the ITT will specify if this applies.

It's also common for the buyer to come back with clarification questions on your submission during evaluation — points where a panel wants you to confirm or expand on something you've already written, rather than an invitation to submit new material. Respond promptly and precisely; a slow or vague reply to a clarification request reflects as poorly as a weak original answer.

Beyond that, you generally won't hear much else during evaluation. Radio silence for several weeks is normal — it means the panel is scoring, not that anything has gone wrong.

Stage 8 — Award, standstill, and feedback

When evaluation is complete, the buyer notifies all bidders of the outcome. Under the Procurement Act 2023, buyers must issue an award notice and provide a summary of the scores and reasons for the decision.

There is then a mandatory standstill period — currently eight working days for contracts above threshold — during which unsuccessful bidders can challenge the decision before the contract is formally signed. Challenges are rare but do happen, particularly on high-value contracts where the margin between bidders is close.

If you're unsuccessful, you're entitled to a debrief. Request one. Understanding why you lost — specifically which criteria you scored lower on and why — is the most valuable feedback you can get. Most businesses don't request debriefs, which means they repeat the same mistakes across multiple submissions. The businesses that improve their win rates consistently are usually the ones that treat every loss as a structured learning exercise.

What changed under the Procurement Act 2023

The Procurement Act 2023, which came into force on 24 February 2025, made several changes to the process above.

PQQs replaced by standardised SQs. The intention is that suppliers register their standard information once on the Central Digital Platform rather than completing bespoke pre-qualification documents for every buyer. Adoption is still rolling out.

MAT replaced MEAT. Most Advantageous Tender replaced Most Economically Advantageous Tender, reflecting the explicit inclusion of social value and broader quality criteria in evaluation.

Greater transparency. Buyers must publish more information about procurement decisions, including award notices with scores and reasons. This creates more post-award intelligence for suppliers building their market knowledge.

Revised exclusion grounds. The Act updated the grounds on which buyers can exclude suppliers, with clearer rules around discretionary exclusion and self-cleaning.

Direct award constraints tightened. Buyers have less flexibility to award contracts without competition, which in principle opens more opportunities to new entrants.

Typical timelines

These are representative ranges, not guarantees. Complex contracts, contested evaluations, and internal approval processes can extend any stage significantly.

The implication for pipeline planning: if you identify an opportunity at market engagement stage, you may be six to nine months from mobilisation. If you only pick it up at the contract notice stage, you're joining a process that's already well underway for buyers — and potentially for incumbent suppliers who've been tracking it since the PIN.

Where processes go wrong

Timelines slip — usually at market engagement. Buyers underestimate the time needed to finalise a specification after market engagement, and internal approvals add further delay. If you're planning business development around an expected contract notice date that came out of market engagement conversations, build in contingency.

Portals are unpredictable. Different buyers use different portals — Jaggaer, Proactis, Delta, In-Tend, and others — each with their own quirks. Register early on whichever portal the buyer uses and familiarise yourself with the submission interface before the day you need it.

Evaluation criteria shift between stages. The SQ and ITT sometimes carry different weightings and criteria. Read both carefully rather than assuming the SQ criteria tell you how the ITT will be scored.

Debriefs get skipped. Requesting a debrief feels uncomfortable when you've just lost a contract. Do it anyway. Buyers are required to provide feedback and most will give useful detail if asked directly.

FAQ

How long does the UK tendering process take from start to finish?

From first visibility to contract award, most public sector tenders take between four and nine months. Larger, more complex procurements — particularly those involving extensive market engagement or multi-lot evaluation — can run longer. Planning your business development pipeline around typical tender timelines is more reliable than chasing individual opportunities with no sight of where they are in the process.

Do I have to complete a Selection Questionnaire for every tender?

Not always. Single-stage processes combine the SQ and ITT into one submission. Below-threshold contracts often skip the SQ entirely. Where an SQ is required, the Procurement Act 2023 introduced a standardised format intended to reduce duplication — though in practice, buyers still vary in how they implement it.

What happens if I miss the submission deadline?

Your response will almost certainly be rejected. Buyers have very limited discretion to accept late submissions, and most don't use it. Portal problems, computer issues, and last-minute file errors are not accepted as reasons for lateness. Submit at least 24 hours before the deadline.

Can I ask the buyer questions after I've submitted my tender?

Generally no. The window for you to raise clarification questions is during the ITT period, before the deadline — once you've submitted, that channel closes. What can happen after submission is the reverse: the buyer may come back to you with clarification questions about your response, usually to resolve an ambiguity rather than to invite new information. You can't use a buyer's clarification request as an opportunity to revise or add to your bid — respond only to what's been asked. Some buyers also hold presentations or site visits as part of evaluation, which will be specified in the ITT if they apply.

What is the standstill period and does it affect me?

The standstill period is a mandatory gap between the award notification and contract signature. It currently runs for eight working days on contracts above the relevant threshold. During standstill, unsuccessful bidders can challenge the award decision. If you've won, the standstill period means you can't formally start work until it expires. If you've lost, the standstill period is your window to request a debrief and, if you believe the evaluation was flawed, to raise a formal challenge.

What's the difference between Contracts Finder and Find a Tender?

Contracts Finder covers contracts above £12,000 with central government and above £30,000 with other public bodies. Find a Tender Service (FTS) covers contracts above the higher procurement thresholds — currently £139,688 including VAT for most central government goods and services. Both are free to use. Many buyers also publish on sector-specific portals in addition to these national platforms.
