Finding contracts before they are re-tendered
By the time a tender is published, the specification is written, often with help from the supplier who already holds the work. The only point at which a challenger can influence anything is before that, and public data tells you when it is.

The problem with reading tender notices
Watching for new notices feels like the obvious way to find work. It is also the latest possible moment to arrive.
A public sector re-tender has a long private history before it becomes a notice. Someone reviews the current service, decides to renew or replace it, scopes what is needed, often speaks to the incumbent about what has and has not worked, writes a specification, gets it approved and then publishes.
If your first contact with that process is the published notice, you are responding to a document shaped by other people's conversations, on a three-week clock, against a supplier who has been part of it for months.
Award notices tell you when
When a contract is awarded, the notice commonly publishes the contract end date. That single field turns a future competition into a known date.
It means the re-tender for a five-year contract awarded in 2024 is visible now, in public data, to anyone who looks. Almost nobody does, because the information sits in award notices, which most suppliers ignore as a record of a competition they already lost.
How much is out there
21,149 UK public sector contracts have a published end date in 2027 alone, across 2,266 buying organisations. Every one is a re-tender with a date already attached.
How often does the incumbent actually lose?
The received wisdom is that you should not bother competing against an incumbent. If that were true, no public contract would ever change hands. So we measured it against our own award data.
Taking contracts where the same buyer awarded the same named contract again at least six months later, where a single supplier was named each time, and where the two awards are not call-offs under a framework: 754 re-tenders since 2021, and 230 of them, 30.5%, went to a different supplier.
Close to a third. Incumbency is an advantage, not a lock, and treating it as a lock is why a good many capable firms never bid at all.
How this was counted, and what it misses
Suppliers are compared by resolved identity, not by name, because “Microsoft Ltd” and “Microsoft Limited” are one company and counting them as a change of hands overstates the result. Contracts are matched on an exact title, so a re-tender that was renamed is invisible to this, and framework call-offs are excluded because a rotating list of suppliers under one arrangement is not an incumbent being displaced. It is a real measure of a real subset rather than a figure for the whole market, and the honest reading is roughly three in ten, not a precise 30.5.
What to do with a date
A date twelve to eighteen months out is not a sales opportunity yet. It is a research opportunity that becomes a sales opportunity.
- Read the original award. Value, duration, lot structure, who won, what the specification covered. That tells you what the buyer thought they needed last time and roughly what they paid.
- Work out whether it is contestable. An incumbent performing well on a service the buyer is happy with is a poor target. A service that has visibly struggled, or a specification that is clearly dated, is a good one.
- Make contact before the procurement starts. Ask what they are planning, offer to take part in market engagement, and be useful about the problem rather than pitching your product.
- Be ready when it lands. Having your evidence, references and pricing straight before the notice appears is worth more than any amount of speed afterwards.
Where the line is on contact
This matters, so be clear about it. Talking to a buyer before a procurement begins is normal and encouraged: buyers run market engagement events for exactly this reason, and a supplier who helps them understand what the market can do is doing them a favour.
Once a competition is live, the rules change completely. Use only the communication route named in the tender documents, usually the portal messaging function, and do not approach evaluators. The two situations are different, and knowing which one you are in is the whole of the etiquette.
Doing this without a subscription
All of it is public. You can search award notices on Contracts Finder and Find a Tender, filter by category and buyer, and record end dates in a spreadsheet. For a handful of target buyers that is genuinely workable, and worth doing before paying anyone.
It stops being workable at scale, because end dates are scattered across four portals and hundreds of thousands of notices, buyer names are spelled inconsistently, and framework values distort any attempt to rank by size. That is the gap tools exist to fill, ours included.
- Browse what is coming on our expiring contracts pages, by year.
- Look up a specific organisation on the buyer pages to see what they hold and when it ends.
- Check a competitor on the supplier pages to see which of their contracts are coming up.
One caveat worth keeping
Not every award notice publishes an end date, and some that do are wrong or get extended. Any count of expiring contracts is a floor, not a complete picture, and a date should be treated as a strong signal rather than a diary entry.
It is still the most useful under-used information in UK public procurement, precisely because it is hiding in plain sight.
Common questions
Getting in early
How do I find public sector contracts before they are advertised?
Read the award notices rather than the tender notices. When a contract is awarded, the notice usually publishes its end date, so the re-tender is visible from the moment the current contract starts. That information is public, scattered across four portals and hundreds of thousands of notices, which is why almost nobody uses it.
When does re-tendering actually start?
Commonly three to six months before the contract ends, and a year or more for large or complex services. Internal planning starts earlier still. By the time the tender is published the specification is written, so the useful conversation happens well before that.
Is it worth contacting a buyer before a tender is published?
Yes, and it is entirely legitimate before a live procurement begins. Buyers routinely run market engagement precisely to understand what suppliers can offer. What you must not do is approach evaluators outside the permitted channel once a competition is live, which is a different thing at a different time.
Do incumbents usually win when a contract is re-tendered?
Not always. Across 754 UK public sector re-tenders since 2021, where the same buyer awarded the same named contract again at least six months later to a single named supplier, 30.5% went to a different supplier. Close to a third changed hands. Incumbency is a real advantage but it is not a lock, and the common advice never to bid against an incumbent is wrong about a third of the time.
Do all award notices publish an end date?
No, which is why any count of expiring contracts is a floor rather than a complete picture. Enough do to make it the single most useful under-used signal in public procurement.
