Most suppliers still treat the tender notice as the starting gun. It goes live, the clock starts, and everything from the bid/no-bid decision to case study gathering happens inside whatever response window the buyer has allowed. That was always a stretch. Under the Procurement Act 2023, it can become a genuine problem because the applicable minimum tendering period can, in some circumstances, be as short as ten days.
The counterweight is a notice type that plenty of suppliers still overlook. A Planned Procurement Notice can appear well before the tender itself, telling you an opportunity is coming and giving you time to do something about it. Where it is published between 40 days and 12 months before the Tender Notice, it becomes a qualifying Planned Procurement Notice, which can allow the buyer to use a shorter tendering period later. Used properly, it is one of the most useful early signals available to anyone building a serious public sector pipeline.
What is a Planned Procurement Notice?
Set out in Section 15 of the Procurement Act 2023, a Planned Procurement Notice is an optional pre-procurement notice published on the Central Digital Platform. Its purpose is to give the market advance information about a procurement that the contracting authority expects to advertise later. Cabinet Office guidance says it should provide as much information as is available at that stage so potentially interested suppliers can decide whether the opportunity is worth pursuing and have more time to prepare.
It performs a similar function to the Prior Information Notice, or PIN, that suppliers may recognise from the previous procurement regime. There is an important distinction around timing, though. A Planned Procurement Notice can be published at any point before the Tender Notice. The 12-month period is not an absolute limit. Instead, a notice becomes qualifying when it has been published at least 40 days and no more than 12 months before the Tender Notice. That qualifying status is what gives the buyer the option of reducing the minimum tendering period to ten days.
One point of genuine confusion worth clearing up first: in the Find a Tender notice taxonomy, the Planned Procurement Notice is UK3, while UK2 is the preliminary market engagement notice and UK4 is the tender notice itself. You'll occasionally see it labelled differently in older guidance, so it's worth checking the reference number against the official Find a Tender notice types list rather than relying on memory. And while the abbreviation PPN is tempting, it's best avoided here, because in public procurement that almost always means a Procurement Policy Note, which is a different thing entirely.
Where it sits alongside other pre-tender notices
A Planned Procurement Notice is only one of the signals you might see before a formal tender appears.
- A Pipeline Notice provides much earlier visibility of future purchasing activity. Large contracting authorities with annual procurement spend above £100 million are required to publish a UK1 notice for qualifying opportunities valued above £2 million that fall within their upcoming 18-month pipeline. The collection of those individual notices forms the authority's wider procurement pipeline.
- A Planned Procurement Notice is more closely tied to a specific procurement. Its purpose is to provide enough advance information for interested suppliers to assess the opportunity and start preparing.
- A Preliminary Market Engagement Notice serves a different purpose again. It can invite suppliers to take part in forthcoming engagement, such as supplier meetings or questionnaires, or tell the wider market about engagement that has already taken place.
These notices can appear in different sequences. For example, a procurement might move from a Pipeline Notice to preliminary market engagement, then to a Planned Procurement Notice and finally to a Tender Notice. But not every procurement will follow exactly the same path. We've covered the wider regime in our guide to how tender notices work under the Procurement Act.
The ten-day trade-off
If a Planned Procurement Notice has been published at least 40 days and no more than 12 months before the Tender Notice, the buyer can choose to reduce the applicable minimum tendering period to ten days.
That does not mean every procurement with a Planned Procurement Notice will suddenly give you ten days to respond. Twenty-five days remains a common minimum where tenders are submitted electronically and all of the associated tender documents are available with the Tender Notice, while other periods apply in different circumstances.
Buyers also still have to consider whether suppliers have sufficient time to understand the procurement and prepare an appropriate response. The Cabinet Office specifically reminds authorities to consider the Procurement Act's objectives, including reducing barriers faced by SMEs, before shortening the period.
However, it's important to be aware of the possibility. Ten days is not much time to write a strong bid from scratch, gather fresh evidence, arrange new accreditations, agree subcontracting arrangements or discover halfway through the response that your financial information isn't ready.
The basic trade-off is straightforward: suppliers can receive earlier warning, and buyers can potentially run a shorter formal tender period. That only works in your favour if you actually use the warning.
What to do when Planned Procurement Notices appear
Treat a Planned Procurement Notice as the point at which preparation begins, not as a diary entry to revisit later. Start with a genuine bid/no-bid assessment while you still have room to change the answer. Does the opportunity fit your existing services? Do you have credible experience? Are there requirements you currently couldn't satisfy? Is the likely contract size sensible for the business?
If the opportunity looks like a stretch, you may now have months rather than days to close the gap. That could mean finding a partner, obtaining an accreditation, developing a stronger example of relevant delivery or addressing a weakness in your commercial position.
Then work on the things that take real time. Case studies worth using are usually easier to gather while the work is still fresh than under a live tender deadline. The same applies to referee permissions, insurance evidence, policy documents, financial standing information and certifications.
It's also the right moment to plan your capacity. If the tender notice eventually lands with a short response window, who is writing the submission? Who is reviewing it? What other bids or operational commitments are likely to be competing for their time?
This is also where an opportunity tracking system becomes genuinely useful rather than simply acting as a list of live tenders. Thornton & Lowe's Tender Pipeline is designed to help suppliers monitor public-sector opportunities and build a view of what may be coming up, rather than only reacting once a deadline is already running.
Finally, use the notice as an engagement prompt. If a UK2 notice follows, or the authority announces supplier events or other preliminary market engagement, take that opportunity seriously. Early engagement can help you understand what the buyer is trying to achieve, while giving the authority legitimate market insight before it finalises its procurement.
Limitations worth understanding
Planned Procurement Notices are genuinely useful, but they're not a guarantee. The first limitation is the amount of information available. Because authorities only have to publish what's available at the time, a notice issued twelve months out may tell you very little beyond the broad subject matter and an approximate timescale A notice published a long way in advance may therefore still leave important questions unanswered. Treat an early Planned Procurement Notice as useful intelligence about the likely requirement and timetable, not evidence that every detail has already been decided.
The second limitation is that a Planned Procurement Notice does not commit the authority to running the procurement. It signals an intention, not an obligation, and procurements get cancelled, restructured or absorbed into something else all the time. Where an authority decides not to proceed, good practice is to publish a procurement termination notice, but you shouldn't plan on the basis that every notice becomes a live tender. If the procurement changes substantially before the tender notice appears, the authority may also need to publish a fresh notice and reset the timing, so the dates in an early notice are indicative rather than fixed.
Material changes can also affect the notice's qualifying status. If the procurement changes significantly before the tender notice is published, the authority may need to publish a new Planned Procurement Notice and allow that notice to qualify before relying on the reduced tender period. Alternatively, it can proceed without relying on the shortened timeframe. Build the opportunity into your pipeline, but don't treat the early dates as immovable.
Building this into how you work
The practical shift here is small but meaningful. Instead of monitoring only for Tender Notices and reacting, you're monitoring the whole pre-procurement stage and using each signal to decide whether something deserves attention.
A Pipeline Notice might tell you a buyer expects to purchase something relevant over the next 18 months. Preliminary market engagement can tell you that the requirement is beginning to take shape. A Planned Procurement Notice can be the point where the likely procurement becomes concrete enough to justify serious preparation. By the time the tender notice appears, you ideally aren't starting from zero.
That fits a wider pattern in how the Procurement Act has operated since it came into force. Earlier visibility is only useful if suppliers actually use it. As we've seen in our review of what the Procurement Act has changed in practice, preliminary market engagement and newer routes such as open frameworks create more opportunities to prepare before the traditional tender window. The principle is the same here. The businesses that benefit most from greater transparency will usually be the ones that turn early information into practical preparation.
How Thornton & Lowe can help
Shorter tender windows punish disorganisation more than they punish a lack of capability. The businesses that cope well are usually the ones with their evidence base, case studies, compliance material and internal review process already in reasonable shape before the Tender Notice appears.
At Thornton & Lowe, we help suppliers build exactly that readiness, from tracking upcoming public-sector opportunities to strengthening the underlying material their bids draw on and supporting live submissions when the formal procurement begins.
If you regularly find that tenders are arriving faster than your team can realistically respond to them, the answer isn't simply to write faster. It may mean improving how you identify opportunities, qualify them and prepare before the deadline starts. That's a solvable problem, and one we can help with.
