Procurement procedures
Competitive dialogue
Written by Justin Cesman, CEO of Skim. Last reviewed:
- Definition
- Competitive dialogue was a UK procurement procedure for complex contracts in which the buyer held structured, confidential discussions with shortlisted suppliers to develop a solution before inviting final tenders. Used when the technical specification could not be defined upfront, it has been absorbed into the competitive flexible procedure under the Procurement Act 2023.
Key takeaways
- Competitive dialogue was used for complex contracts where the buyer knew the outcome needed but not the technical solution — major IT systems, infrastructure, and PFI-style deals.
- Under PCR 2015 (Regulation 30) the buyer shortlisted at least three suppliers, ran a confidential dialogue phase with each, then closed dialogue and invited final tenders against a refined specification.
- As a named procedure it is abolished under the Procurement Act 2023; a dialogue-style process can now run inside the competitive flexible procedure, which buyers design themselves.
- Whether legacy or current-Act, the process is months long and senior-people-heavy, so the bid/no-bid decision carries more weight than on a standard tender.
- For SMEs the upside is real — solution design and flexibility count more than scale — but the pursuit cost is high, which is why picking the right dialogue to enter is the decisive move.
How it works
Competitive dialogue was reserved for contracts the buyer could not specify in advance — the outcome was clear but the route to it was not. Under the Public Contracts Regulations 2015 (Regulation 30) it ran in three phases. First a selection stage: the buyer published a contract notice and shortlisted candidates against published criteria, inviting at least three suppliers to the dialogue, provided at least three met the criteria.
Next came the dialogue phase. The buyer met each shortlisted supplier individually and in confidence to develop one or more solutions, free to discuss any aspect of the procurement — technical design, commercial model, risk allocation, financing, delivery method. The dialogue could run in successive rounds to narrow the field of solutions. Once satisfied that one or more solutions could meet its needs, the buyer closed the dialogue and moved to final tenders, which were evaluated on the best price-quality ratio.
The closest cousin was the competitive procedure with negotiation. The grounds for using either were the same, but the starting point differed: under the negotiated route the buyer set minimum requirements and a description of need, then negotiated tenders to improve them; under competitive dialogue the buyer started from a needs description and let suppliers help define the solution itself. That is the practical line between the two — refining a tender against fixed requirements versus co-designing the requirement.
Under the Procurement Act 2023 there is no standalone competitive dialogue procedure. Buyers now choose between the open procedure and the competitive flexible procedure, and a dialogue-style process is run inside the latter when the requirement is complex. The mechanics a bidder experiences — confidential discussions, iterative solution development, a final-tender stage — survive; what changes is that the buyer designs the stages rather than following a fixed regulatory template, so each competition's rules must be read from its tender notice and documents rather than assumed.
Competitive dialogue vs competitive procedure with negotiation (PCR 2015)
| Feature | Competitive dialogue | Competitive procedure with negotiation |
|---|---|---|
| Starting point | A description of the buyer's needs | Minimum requirements plus a description of needs |
| What is developed | The solution itself, co-designed with suppliers | The tenders, negotiated against fixed requirements |
| Best suited to | Contracts the buyer cannot specify upfront | Contracts with defined requirements needing refinement |
| Supplier engagement | Structured dialogue to define the means | Negotiation to improve tender content |
| Status under Procurement Act 2023 | Abolished as a named procedure | Abolished as a named procedure |

Whether competitive dialogue still exists as a procedure depends on when the procurement started. The Public Contracts Regulations 2015 (PCR 2015) governed it for procurements begun before 24 February 2025, when the Procurement Act 2023 came into force. Under the Act there is no longer a standalone competitive dialogue procedure — the six EU-style procedures are reduced to two, the open procedure and the competitive flexible procedure. Cabinet Office guidance confirms there is no longer a restricted, competitive-procedure-with-negotiation or competitive dialogue procedure, but that a similar dialogue-based approach can be adopted within a competitive flexible procedure where appropriate and compliant with the Act. In practice the dialogue mechanics survive; what changes is that the buyer designs the stages rather than following a fixed template, so bidders read each competition's rules from its tender notice.

Why it matters for bidders
Competitive dialogue contracts — and the complex competitive flexible procedures that now replace them — tend to be high-value and long-term, so winning one can reshape a business. But the pursuit cost is steep: months of dialogue, senior team time, and real solution design before a single tender is submitted. That makes the choice of which dialogue to enter the highest-leverage decision in the whole pursuit. The signal most bidders miss sits in the buyer's published award history: which incumbents win this buyer's complex work, how solutions were scored, and whether the buyer has a pattern of running genuine dialogue or steering toward a favoured design. Reading that record before committing — a discipline drawn from teams who have won over £3bn in UK and EU public contracts — is what separates a dialogue worth months of senior time from one already lost on day one.
How Skim helps
Skim's Buyer Intelligence agent analyses the buying organisation's history, preferences, and past awards to help you judge whether a competitive dialogue or complex flexible-procedure pursuit is winnable before you commit months of senior team time — and its Competitor Analysis agent models which suppliers win this buyer's complex contracts from published award data, so the bid/no-bid call rests on the buyer's actual behaviour, not the brochure.
Frequently asked questions
- What is competitive dialogue in procurement?
- Competitive dialogue is a public procurement procedure for complex contracts where the buyer cannot define the technical specification in advance. The buyer shortlists suppliers, holds confidential discussions to develop a solution, then closes the dialogue and invites final tenders against the refined specification.
- When is competitive dialogue used?
- Competitive dialogue was used for complex contracts where the buyer knew the outcome required but not how to achieve it — large IT systems, major infrastructure, and PFI-style deals. It applied when the technical specification or the legal and financial structure could not be established with precision upfront.
- Has competitive dialogue been abolished under the Procurement Act 2023?
- Yes. As a named procedure, competitive dialogue was abolished when the Procurement Act 2023 came into force on 24 February 2025. The six EU-style procedures were reduced to two: the open procedure and the competitive flexible procedure. A dialogue-style process can still run within the competitive flexible procedure.
- What is the difference between competitive dialogue and the competitive flexible procedure?
- Competitive dialogue was a fixed procedure under PCR 2015 with set stages. The competitive flexible procedure, introduced by the Procurement Act 2023, lets the buyer design its own stages. Dialogue with suppliers can sit inside it, but the rules are defined per competition rather than by a regulatory template.
- What is the difference between competitive dialogue and competitive procedure with negotiation?
- Both applied to complex contracts on the same grounds. Under competitive dialogue the buyer started from a needs description and co-designed the solution with suppliers. Under the competitive procedure with negotiation the buyer set minimum requirements and a description of needs, then negotiated to improve tenders against them.

Restricted procedure
The restricted procedure is a two-stage UK procurement process under the Public Contracts Regulations 2015 in which suppliers first complete a selection questionnaire and the buyer shortlists at least five qualifying candidates, who alone are then invited to submit a full tender.
Negotiated procedure without prior publication
The negotiated procedure without prior publication is a procurement route under the Public Contracts Regulations 2015 that lets a buyer negotiate directly with one or more suppliers without advertising a contract notice. Permitted only in narrow cases such as extreme urgency, a single capable supplier, or no suitable tenders received.
Bid/no-bid decision
A bid/no-bid decision is the structured assessment a supplier makes before pursuing a tender, weighing strategic fit, win probability, resource cost, commercial value, and risk to decide whether the opportunity is worth bidding for — concentrating limited bid effort on winnable, profitable work rather than chasing every notice.
Open procedure
The open procedure is a single-stage public procurement route, defined in section 20 of the Procurement Act 2023, where any interested supplier may submit a full tender with no pre-qualification or shortlisting. The contracting authority then awards the contract on the basis of those tenders alone.
