UK Procurement Procedures Explained for SMEs

Before you read the procedure name, check which regime the tender sits under. It changes what the procedure even means.

England and Wales, on or after 24 February 2025: Procurement Act 2023. You will see two procedures only - open, or competitive flexible. Wales adds a social-partnership overlay but uses the same two procedures.

Anything that started before 24 February 2025: still the old PCR 2015, so you may see the full set of named procedures below. These run to completion under the old rules even years later.

Scotland: a completely separate regime (the Procurement Reform (Scotland) Act 2014 and related regulations). PA23 does not apply. Scottish tenders still use the classic named procedures and live on the Public Contracts Scotland portal, with lower thresholds (around £50,000 for goods and services, £2m for works).

NHS England clinical services are different again - many run under the Provider Selection Regime, not PA23 at all.

• ·If the notice is on Find a Tender and dated 2025 onwards: think PA23, two procedures.
• ·If it is on Public Contracts Scotland: think Scottish regime, named procedures.
• ·If in doubt, the tender documents state the procedure and the regime on the first page or two.

The open procedure is the simplest. There is no shortlisting round. The buyer publishes the tender, and anyone who wants the work submits a full bid by the deadline. Everyone is assessed against the same published criteria, and the best-scoring compliant bid wins.

Buyers use it when the requirement is well-defined and they do not expect a flood of bidders that would make evaluating every full submission unmanageable. Think cleaning contracts, standard supplies, routine maintenance, defined professional services.

For a small bidder this is the most accessible route and often the best value for your effort. There is no gate to pass before you can compete - you are in from the moment you submit. The trade-off is that you write the entire bid up front with no guarantee anyone else has dropped out, and you may be one of many. You still have to clear the pass/fail checks (insurance, financial standing, relevant experience) but under the open procedure those are assessed alongside your bid rather than as a separate earlier round.

• ·One stage, one submission, no shortlist.
• ·Best for you when the spec is clear and you can evidence you meet it.
• ·Watch the effort-to-odds ratio: everyone who bids writes a full response.

This is the big change under PA23, and the one that trips people up. The competitive flexible procedure is not a fixed process. It is a licence for the buyer to design their own multi-stage procedure to suit the contract, as long as they publish how it will run before it starts.

In practice it absorbs everything the old named procedures used to do. A buyer might build a two-stage process with a shortlisting round then full bids (what used to be called restricted). They might build in rounds of dialogue or negotiation. They might run a demo or presentation stage. The shape is whatever they decided, and it is set out in the tender notice and documents.

So the single most important thing you can do with a competitive flexible procurement is read the process description carefully. It tells you how many stages there are, whether there is a shortlist, whether you will get to talk to the buyer, and the timings. Two competitive flexible procedures on the same day can be completely different animals.

For a small bidder this can cut either way. A well-designed one with a light shortlisting stage saves you writing a full bid before you know you are in contention. A heavy one with multiple dialogue rounds and presentations demands real time and senior people in the room, which is harder for a lean team to resource.

• ·No fixed shape - read the published procedure description first.
• ·Look for: number of stages, is there a shortlist, is there dialogue or negotiation, and the dates.
• ·Judge the resourcing honestly - multiple stages mean repeated demands on your time.

On pre-2025 English tenders and on Scottish ones, you will still see the classic named procedures. Here is what each one means and what it changes for you.

Restricted procedure. Two stages. First you complete a selection questionnaire (the SQ or PQQ) covering your capability, experience, insurance and financial standing. The buyer scores that and shortlists a set number of suppliers - often five or six - who are then invited to submit a full tender. The advantage for you is real: you only write the full bid if you make the shortlist, so your wasted effort is capped at the questionnaire if you do not get through. Buyers use it when they expect strong interest and want to keep the number of full bids manageable.

Competitive dialogue. Used for complex contracts where the buyer knows the outcome they want but not how to specify the solution - large IT systems, major regeneration, complex service redesign. After a selection stage, shortlisted bidders enter a dialogue phase where the buyer discusses possible solutions with each before final tenders are invited. It is thorough and it is slow. For a small bidder it is resource-heavy: expect multiple meetings and evolving requirements over months, which favours firms with people to spare.

Competitive procedure with negotiation. Similar shape to restricted - selection, then invited tenders - but with rounds of negotiation on the bids before a final version is submitted. Buyers use it when requirements cannot be met by readily available solutions or need some tailoring. For you, the upside is that a first bid which is not perfect can be improved through negotiation; the cost is the extra time and the commercial skill needed to negotiate well.

Innovation partnership. The rarest. Used when the buyer needs something that does not yet exist and wants a partner to develop it and then buy the result. It combines selection, negotiation and a research-and-development phase. Long, specialised, and usually aimed at bidders with genuine R&D capability - not a typical route for a small services firm.

• ·Restricted: shortlist first, full bid only if you get through - effort-friendly.
• ·Competitive dialogue: complex, slow, meeting-heavy - resource carefully.
• ·Negotiation: your bid can improve through rounds - bring commercial nous.
• ·Innovation partnership: R&D partnership, specialist and rare.

Whatever the procedure, there are always two different tests, and knowing which is which stops you wasting effort in the wrong place.

Conditions of participation (under PA23, section 22) are pass/fail. They ask whether you as a supplier are capable and legitimate: do you hold the required insurance, meet the financial-standing test, have relevant experience, hold the right certifications. You either clear the bar or you do not. There are no extra points for exceeding it.

Award criteria (section 23) are comparative and about the quality of your actual bid: your method, your social value, your price, your added value. This is where you win or lose against rivals.

The practical lesson: get the pass/fail conditions nailed cleanly and early, because failing one knocks you out no matter how good your bid is. Then pour your real effort into the award criteria, because that is the only place your bid can beat someone else's. Buyers are not allowed to score the same factor in both, so do not pad your quality answers with capability boilerplate.

Procedure choice drives how long you wait and how much runway you get to bid.

The open procedure is quickest end to end because there is only one stage. Two-stage procedures (restricted, or a multi-stage competitive flexible one) take longer because of the selection round, and dialogue, negotiation and innovation routes are the slowest, sometimes running for many months.

Whatever the route, once the buyer picks a winner there is a mandatory standstill period of at least 8 working days before they can sign. That is your window: if you were not chosen, you are entitled to feedback (an assessment summary telling you how you scored and why), and standstill is the time to read it, ask questions and, if something looks genuinely wrong, take advice quickly. The clock on any formal challenge is tight - broadly around 30 days from when you knew or should have known of a problem - so do not sit on a bad debrief.

For bid planning, the useful habit is to map the stages and dates from the notice before you commit, so you know when the big efforts fall and whether you can staff them.

Three routes you will also hear about, briefly.

Direct award: the buyer awards without competition, allowed only on narrow legal grounds (for example genuine extreme urgency or where only one supplier can deliver) and with a published transparency notice - so it is the exception, not something you can bid into.

Frameworks and dynamic markets (DPS): pre-approved supplier lists the buyer runs mini-competitions from or calls off directly, so getting appointed to the right framework or dynamic market is often the real gateway to a steady stream of public work.

We cover getting onto frameworks and dynamic markets in more depth in a separate guide - they deserve their own space because for many SMEs they are the most reliable way in.
