Before a public sector buyer evaluates your proposed solution, it needs to establish whether your organisation has the capacity and ability to deliver the contract. Under the Procurement Act 2023, that assessment can involve conditions of participation, which set the requirements suppliers must satisfy to be considered for award.
For bidders, these requirements deserve just as much attention as the scored quality response. A well-written tender cannot compensate for a condition of participation that you ultimately fail to meet, and in a multi-stage competition it may prevent you from progressing to the next stage.
What are conditions of participation?
Section 22 of the Procurement Act 2023 allows contracting authorities to set proportionate conditions relating to a supplier’s legal and financial capacity or technical ability to perform a public contract. Conditions must be relevant to the nature, complexity and cost of the requirement, rather than creating unnecessary barriers to competition.
They are different from the award criteria used to assess the bid itself. Conditions of participation ask whether the supplier can deliver; award criteria help the buyer decide which qualifying tender offers the most advantageous response. The government’s conditions of participation guidance explains this distinction and how buyers can apply the rules.
Assessment | Central question | Typical evidence |
|---|---|---|
Conditions of participation | Can this supplier perform the contract? | Financial capacity, relevant experience, qualifications, available resources |
Award criteria | How strong is this tender against the buyer’s published requirements? | Method statements, delivery proposals, pricing, measurable outcomes |
Exclusion checks | Is there a statutory reason to exclude or consider excluding the supplier? | Relevant declarations and information under the separate exclusions regime |
These assessments can take place at related stages, but they should not be treated as interchangeable. A supplier should read the specific tender notice and documents carefully to identify the mandatory conditions, assessment methodology and evidence requirements.
What evidence might a buyer request?
The exact questions will depend on the contract. A low-value local service contract should not impose the same evidential burden as a complex national infrastructure programme, although suppliers should expect each published condition to have a clear method of assessment.
Legal and financial capacity
Buyers may examine whether a supplier has sufficient financial resources to fulfil the contract and whether the business can legally undertake the required work. Evidence might include financial statements, proportionate financial assessments, licences where needed, and information about insurance arrangements.
There are important safeguards for smaller businesses. Authorities cannot require audited annual accounts from a supplier that is not otherwise required to have them audited under the Companies Act 2006 or an overseas equivalent. Nor can they insist that insurance relating to contract performance is already in place before award, although a commitment and appropriate evidence that it will be available may be needed.
Technical ability and relevant experience
Technical conditions may consider comparable delivery experience, qualifications, specialist equipment, staffing and the systems needed to perform the contract. Suppliers should prepare concise examples demonstrating the scale, complexity and outcomes of relevant work rather than relying on a generic list of clients.
The Act prevents a condition from requiring previous contract awards by a particular contracting authority, and specified qualifications must permit equivalent qualifications. This matters where SMEs or new entrants can demonstrate the capability required without having worked for the exact buyer before.
How are conditions assessed in an open or competitive flexible procedure?
In an open procedure, conditions may be assessed alongside the tender, with the buyer separating its supplier-capability judgement from the scoring of the tender response. Under a competitive flexible procedure, conditions can also be used at an initial participation stage to shortlist suppliers before they are invited to submit full tenders.
Assessment is not necessarily limited to a simple pass or fail at the outset. A buyer may use objective criteria published in the tender notice to score participation responses and limit the number of suppliers progressing, provided the procedure complies with the Act. Some conditions may be verified later in the procurement, but every condition must ultimately be satisfied for contract award.
Can a supplier rely on a consortium or subcontractor?
In some procurements, a supplier can meet a condition by relying on another organisation, such as a consortium partner, specialist subcontractor or guarantor. This can open opportunities where no single organisation has every required capability, but the proposed arrangement must be genuine and consistent with the published conditions.
Depending on the relationship, the authority may need assurance that legally binding arrangements will be entered into. Suppliers should identify precisely which organisation supplies each capability, check any associated-person requirements and ensure their supporting evidence is available in the right format.
Common participation mistakes
One frequent mistake is treating the participation section as a basic administration exercise. Mandatory requirements often rely on project-specific detail or external verification, so gaps may take considerably longer to resolve than writing the technical response.
- Assuming a previous public sector contract automatically proves the required experience without mapping it to the stated condition.
- Submitting broad capability statements where the buyer asks for dated projects, contract values or named outcomes.
- Leaving financial, qualification or insurance evidence until immediately before the deadline.
- Failing to identify the subcontractor or consortium member relied upon to meet a particular condition.
- Confusing a mandatory participation requirement with a scored quality question and allocating resource accordingly.
Another avoidable problem is preparing evidence against an older version of the tender pack. Clarifications or amendments may change the wording or required attachments, so the bid manager should maintain a controlled requirements register throughout the process.
How to prepare a conditions of participation evidence matrix
An evidence matrix provides a simple way to identify missing information before it threatens a submission. Use the buyer’s exact language in the requirement column and assign a named owner and deadline to each item.
Requirement | Evidence to assemble | Owner and check |
|---|---|---|
Financial capacity | Relevant accounts or alternative financial evidence | Finance lead; verify reporting period and format |
Relevant experience | Comparable case studies with values, dates and outcomes | Delivery lead; confirm customer references |
Qualifications | Certificates or evidence of equivalent qualifications | Operations lead; check validity |
Partner capability | Partner evidence and proposed delivery relationship | Bid manager; check reliance arrangements |
Before the final review, compare every proposed answer to the tender notice, not just the questionnaire template. The team should be able to show what satisfies each condition, whether it is complete and what remains dependent on third-party confirmation.
Conditions of participation and the Procurement Specific Questionnaire
Many tenders use a Procurement Specific Questionnaire (PSQ) or another participation template to collect supplier information. The form is a mechanism for gathering relevant answers; it does not mean that every procurement will use an identical list of conditions.
The government’s Central Digital Platform also supports the sharing of core supplier information. Suppliers should keep that information accurate, but still respond to procurement-specific requests in the form and at the time the authority requires. For a wider explanation of the questions and supporting evidence, see our Procurement Specific Questionnaire guide.
How Thornton & Lowe helps suppliers prepare
Strong participation responses start with realistic opportunity selection and early evidence planning. Our bid writing team can review the requirements, identify evidence gaps, coordinate subject matter experts and develop submissions that address both the mandatory conditions and the scored tender questions.
Whether you are entering a two-stage competition or preparing a complex framework application, the aim is to demonstrate capability in the format the buyer has asked for. That gives your organisation the best foundation for progressing to the next stage and presenting a competitive tender.
