Quick answer: The Procurement Act 2023 requires UK public sector buyers to publish a pipeline notice for contracts over £2 million. Most organisations will file it, forget it, and move on. The buyers who treat it as an active market-shaping tool will run better competitions, attract stronger suppliers, and spend less time managing poor tender responses.
What the Act actually requires
From February 2025, contracting authorities with an annual procurement spend above £100 million must publish a pipeline notice setting out anticipated procurements worth £2 million or more in the coming financial year. The notice goes on the Find a Tender Service. It is not optional, and the threshold for the spending duty is lower than many finance teams initially assume when they tot up their figures.
That is the compliance version. Now let's talk about what it is actually for.
The market does not know what you need unless you tell it
Suppliers — particularly SMEs and social enterprises — do not have procurement officers scanning your board papers. They are running businesses. If a £4 million FM contract is coming to market in eight months and the incumbent has already started lobbying, a new entrant has almost no time to prepare a credible bid, arrange references, or put together a joint venture if the lot size is too large for them alone.
A pipeline notice, published properly and early, changes that. It gives the market time to organise itself around your requirement. That is not being kind to suppliers. That is acting in your own interest as a buyer, because a competitive field with prepared bidders produces better outcomes than a thin field where only one organisation knew the opportunity was coming.
Most pipeline notices are nearly useless
I have reviewed pipeline publications from a number of authorities since the Act came into force. The pattern is dispiriting. Contract title: "Grounds Maintenance Services." Estimated value: £2.5m. Anticipated start: Q3 2026. Contact: procurement@[organisation].gov.uk.
That is it. No description of the authority's priorities, no indication of the likely lot structure, no mention of whether social value or a Carbon Reduction Plan will be evaluated, no signal about whether the authority is open to pre-market engagement.
A supplier reading that knows almost nothing useful. They cannot make a sensible decision about whether to invest time in this opportunity or move on to the next one. And you, as the buyer, have lost the chance to start a conversation with the market before the formal process begins.
What a useful pipeline notice actually contains
You do not need to publish your full specification in February. But you can — and should — include enough context to be genuinely useful:
- A brief description of what the contract covers and why it matters to your organisation
- Your broad expectations on social value, including whether you are using a specific framework such as TOMS or your own local weighting
- Whether a Carbon Reduction Plan will be required at the point of contract award, so suppliers understand the compliance bar
- An indication of lot structure if you are planning to break the contract up to encourage SME participation
- Whether you intend to run a pre-market engagement exercise, and how suppliers can register interest
None of that commits you to anything. It just means the market can show up prepared.
Pre-market engagement is not improper — it is good practice
There is still a stubborn myth in some procurement teams that talking to suppliers before a formal process is somehow risky or compromising. The Procurement Act is explicit that pre-market engagement is encouraged, provided it is conducted transparently and any information shared with one supplier is made available to others.
Your pipeline notice is the natural starting point for that engagement. Publish the notice, invite expressions of interest in a market engagement exercise, run an information day or issue a questionnaire. By the time your PIN or tender notice goes live, you will have a clearer picture of market capability, and suppliers will have a clearer picture of what you actually need.
That is how you get better bids.
The supplier development angle
For authorities with genuine commitments to growing local supply chains or diversifying away from a handful of large incumbents, the pipeline is a strategic tool. A supplier development programme that runs alongside your published pipeline — helping SMEs understand forthcoming requirements, access frameworks, build capacity — can meaningfully shift who competes for your contracts over a two or three year horizon. But it only works if suppliers know what is coming and when.
You cannot develop a market you have kept in the dark.
Practical takeaway
Pull up your current pipeline publication and ask honestly: if I were a supplier seeing this for the first time, would I know enough to decide whether to invest in this opportunity? If the answer is no, rewrite it. Add context, signal your priorities, and open a route for pre-market engagement. The pipeline notice costs you nothing extra to do properly — and a thin, unprepared tender field will cost you a great deal more.
