What is a prior information notice in UK procurement?

A prior information notice (PIN) is a voluntary or mandatory procurement notice used in UK public sector procurement to signal an upcoming contract opportunity before the formal tender process begins. It allows contracting authorities to alert the market early, gather supplier interest, and in some cases, reduce the minimum time limits that apply to the main tender. The sections below answer the most common questions about how PINs work, what they must contain, and how both buyers and suppliers should respond to them.

When is a prior information notice used in UK procurement?

A prior information notice is used in UK procurement when a contracting authority wants to inform the market about a planned procurement before issuing a formal contract notice. Under the Procurement Act 2023, which came into force in February 2025, PINs can be used voluntarily to generate early market awareness, or as a call for competition in certain procedures where they replace the contract notice entirely.

There are two main scenarios in which a contracting authority will publish a PIN. The first is as a planning notice, giving suppliers advance warning that a significant contract is on the horizon. This is particularly common for large or complex procurements where early market engagement is commercially valuable. The second scenario is where the PIN is used as a means of inviting expressions of interest, effectively substituting the contract notice in restricted or selective procedures. In this case, the PIN carries more formal weight and triggers specific obligations around timescales and supplier communication.

Public bodies also use PINs to signal intent across a financial year, grouping planned contracts by category or value so that the supplier market can prepare accordingly. This is especially useful in sectors such as healthcare, local government, and higher education, where forward planning is essential for both buyers and providers.

What information must a prior information notice include?

A prior information notice must include enough information to allow suppliers to assess whether the opportunity is relevant to them and to prepare for the upcoming procurement. At a minimum, this includes the contracting authority’s identity and contact details, a description of the subject matter of the contract, the estimated value and duration, and the anticipated timeline for the formal procurement to begin.

Where the PIN is being used as a call for competition rather than a simple planning notice, the information requirements become more specific. In these cases, the notice must also include the procedure type being used, the criteria suppliers will need to meet, and clear instructions on how to express interest or request an invitation to tender. Failing to include the required information can undermine the legal standing of the notice and expose the contracting authority to challenge.

Under the Procurement Act 2023, notices must be published on the UK’s central digital platform, Find a Tender (FTS), which has replaced the old OJEU system for domestic procurement. The platform sets out mandatory data fields that must be completed before a notice can be published, which provides a practical quality check on the information included.

What’s the difference between a PIN and a contract notice?

The key difference between a prior information notice and a contract notice is timing and purpose. A contract notice formally opens a procurement competition and invites suppliers to bid or express interest in a live tender. A prior information notice comes earlier in the process and signals that a procurement is planned, without yet committing to a formal competition.

A contract notice is a mandatory step in most above-threshold public procurements. It marks the point at which the procurement is officially underway and triggers the legal timescales within which suppliers must be given time to respond. A PIN, by contrast, is often optional and does not in itself open a competition unless it is specifically structured as a call for competition.

However, the distinction is not always absolute. When a contracting authority uses a PIN as a substitute for a contract notice in certain procedures, the two documents can overlap in function. In these circumstances, the PIN carries many of the same legal requirements as a contract notice, including minimum response periods and transparency obligations. The critical factor is how the notice is classified and what procedure it is being used to support.

How does a prior information notice affect supplier timescales?

Publishing a prior information notice can reduce the minimum time limits that apply to the subsequent tender process. Under UK procurement rules, if a contracting authority has published a PIN that meets the required conditions, it may be entitled to use shorter standstill and response periods when the formal tender is issued. This makes early publication of a PIN a practical tool for buyers who want to compress overall procurement timescales without compromising compliance.

The reduction in timescales is not automatic. The PIN must have been published a minimum number of days before the contract notice is issued, and it must have contained sufficient information about the forthcoming procurement. If these conditions are not met, the standard minimum periods apply in full.

For suppliers, the practical implication is that a PIN signals the need to act early. Organisations that identify a relevant PIN and engage at the pre-market stage are better positioned when the formal tender opens. They may have contributed to the specification, understood the buyer’s priorities, and already begun assembling the resources needed to bid competitively. Waiting until the contract notice is published means less preparation time, particularly if the contracting authority has legitimately shortened the response window.

Where are prior information notices published in the UK?

In the UK, prior information notices are published on Find a Tender Service (FTS), the government’s central procurement platform at find-tender.service.gov.uk. This replaced the Official Journal of the European Union (OJEU) as the primary publication channel following the UK’s departure from the EU. All above-threshold public sector procurement notices, including PINs, must be published here to comply with the Procurement Act 2023.

Some contracting authorities also publish notices on their own procurement portals or on sector-specific platforms, particularly in local government and the NHS. However, publication on FTS remains the legal requirement for above-threshold contracts, and any additional channels are supplementary rather than substitutes.

Suppliers who want to monitor PINs relevant to their sector should set up alerts on FTS using keyword, category, or authority filters. Many tender management tools also aggregate notices from FTS and other sources, making it easier to track opportunities across multiple buyers without monitoring each platform manually.

Should suppliers respond to a prior information notice?

Suppliers should engage with a prior information notice when the opportunity aligns with their capabilities and strategic goals. While a PIN does not require a formal bid response in the same way a contract notice does, it often invites expressions of interest or participation in pre-market engagement activities. Responding at this stage can meaningfully influence the shape of the final procurement.

Engaging with a PIN gives suppliers the opportunity to meet the buyer, understand their requirements in depth, and contribute to the development of the specification. Buyers running early market engagement exercises are often genuinely open to input, particularly on technical requirements, market capacity, and commercial structure. Suppliers who participate in this process tend to produce stronger bids because they have a clearer understanding of what the contracting authority actually needs.

There are also reputational benefits to early engagement. Being known to the buying team before the formal tender opens is not the same as having an unfair advantage, provided the engagement is conducted transparently. Contracting authorities are required to manage pre-market engagement in a way that does not distort competition, and most experienced buyers are careful to document and share insights from early engagement with all eventual bidders.

That said, suppliers should be selective. Responding to every PIN regardless of fit wastes resources and can dilute the quality of engagement. The most effective approach is to monitor PINs systematically, assess each one against a clear set of criteria, and invest engagement effort where the opportunity is genuinely winnable and strategically worthwhile.
