Supplier guideReviewed 14 September 2026

Procurement Act 2023 for suppliers.

A practical, source-backed guide to the supplier-relevant shape of the current procurement regime: where information can appear earlier, how notices span more of the lifecycle, and where public transparency still stops short of your organisation's own commercial reality.

What changed on 24 February 2025?

The Procurement Act 2023 regime went live on 24 February 2025. It applies to contracting authorities in England, Wales and Northern Ireland and to authorities with reserved functions carrying out procurement in Scotland; devolved Scottish authorities generally remain under separate Scottish procurement legislation. For suppliers, one of the most visible changes is the central digital platform, delivered through the enhanced Find a Tender service, where regulated procurement notices are published.

The official supplier guide describes notices that can show what the public sector plans to buy, tender opportunities, information about the process leading to a contract, and information about awarded contracts through their life. The practical shift is not simply “more tenders online”. It is a wider public trail around the opportunity.

Transparency now reaches across more of the procurement and contract-management lifecycle.

The central platform is designed around notices issued during procurement and into contract management. That means supplier intelligence can sit across a sequence rather than only at the point a tender notice appears.

A simplified lifecycle viewSelected stages, not a legal sequence for every procurement

This matters because the useful question for a supplier can change by stage. A planning notice may be about preparation and market context; a live tender notice is about the actual opportunity; later notices can help build a more complete public record around buyers, contracts and change.

Think of the 17 notice types as a system, not a checklist.

Cabinet Office guidance says there are 17 notice types across procurement and contract management, and that not every notice is used in every procurement. The value for suppliers is therefore in understanding what a notice represents in context, not assuming every opportunity will show the same sequence.

UK1

Pipeline notice

Forward-looking information about expected procurements in the circumstances set by the Act.

UK2

Preliminary market engagement

Can show that an authority is engaging the market before a tender or transparency notice.

UK3

Planned procurement

Optional advance notice that can provide more information about an upcoming competitive procurement.

UK4

Tender notice

The supplier-facing opportunity to tender, with the procedure and information relevant to participation.

UK6

Contract award

Published before entering into the public contract, including award information specified by the regime.

Contract-management notices

Other notice types can provide public information after award, depending on the procurement and contract.

Selected examples only. Find a Tender's notice-types page is the current reference for notice names, sequences and applicability.

Earlier visibility can start before the tender notice.

Three notice types are particularly useful for understanding the pre-tender horizon. They do different jobs, and none should be treated as a promise that a procurement will unfold exactly as first described.

UK1 · PIPELINE

See expected procurements earlier.

Pipeline notices are designed to publish forward-looking procurement information in defined circumstances. Official guidance highlights the planning benefit for SMEs and VCSE suppliers.

Pipeline information may be less detailed than later tender or transparency notices.
UK2 · PME

See where the market is being engaged.

Preliminary market engagement happens before a tender or transparency notice and can help authorities and the market prepare. If an authority conducts PME, the Act generally requires a PME notice before the tender notice or an explanation in the tender notice, subject to stated exceptions.

Engagement is not mandatory for every procurement.
UK3 · PLANNED

See a more developed upcoming procurement.

A planned procurement notice is optional and can give advance information before a tender notice. A qualifying notice published between 40 days and one year before the tender notice can allow the authority to reduce the tendering period to 10 days or more.

The authority still has to apply the regime's requirements when setting time periods.
05 / 08

Conditions of participation are about supplier capacity and ability, with proportionality built into the framework.

Official guidance says conditions of participation can relate to a supplier's legal and financial capacity or technical ability to perform the contract, and must be proportionate having regard to the nature, complexity and cost of the contract.

Supplier-relevant contextTwo explicit restrictions are worth knowing about.

These are high-level examples of how the regime seeks to reduce unnecessary barriers. Always check the tender notice, documents and current official guidance for the procurement in front of you.

01Audited accounts cannot be required as a condition of participation from a supplier that is not otherwise legally required to have its annual accounts audited.Alternative evidence may need to be assessed for financial capacity.
02Contract-performance insurance cannot be required to be in place before award.An authority can require the necessary contractual insurance by contract commencement, provided the condition otherwise complies with the Act.

More published information does not automatically create supplier-specific commercial understanding.

Greater transparency can improve what is visible about an opportunity and its lifecycle. But the public record cannot establish your current capacity, evidence availability, mobilisation dependencies, operating commitments or other supplier-owned context.

WinIntel interpretation
01Public opportunityOfficial and buyer-published information remains the source of record.
02Supplier contextOnly proportionate information your organisation can establish or provide.
03Pre-bid understandingRequirements, dependencies, commercial pressure and unresolved questions kept distinct.

WinIntel does not turn the Procurement Act into a bid/no-bid verdict. Your organisation retains every commercial, procurement, legal, financial and bidding decision.

What should suppliers verify from the original official sources?

Use explanatory guides to orient yourself, then return to the source that controls the live procurement. At minimum, keep these layers separate.

Bring the public opportunity into focus.

Start with one live tender or notice reference. WinIntel reviews the public opportunity first and asks for additional supplier context only where it is material to deeper pre-bid analysis.
