Quick answer: Pre-market engagement is one of the most powerful tools a buyer has — and one of the most routinely mishandled. Done badly, it signals favouritism, narrows your supplier base, and produces specifications that fit one incumbent perfectly. Done well, it sharpens your requirements, surfaces market realities, and builds the competition you actually need.
The problem isn't that buyers skip pre-market engagement. It's that they do it wrong.
Most procurement teams I've worked with know they should talk to the market before they go out to tender. The Procurement Act 2023 reinforces this — preliminary market engagement is explicitly recognised and, when conducted properly, is entirely legitimate. The National Procurement Policy Statement expects buyers to understand their markets. The Green Paper that preceded the Act was clear: better market intelligence leads to better outcomes.
So buyers engage. They send a few emails to suppliers they already know. They invite three or four companies in for a chat. They ask those companies to help draft the specification. Then they wonder why they end up with a procurement process that feels stitched up before it starts — because, functionally, it is.
The incumbent problem
The single most common mistake is conducting pre-market engagement almost exclusively with current suppliers. It feels natural. They know your operation. They're easy to reach. But the intelligence you gather is systematically skewed. Incumbents have every incentive to describe the market in ways that make switching look complex, risky, and expensive. They'll frame capability requirements in terms that describe their own service model. They'll cite compliance burdens that conveniently match their existing systems.
You end up with a specification that isn't technically sole-source — but might as well be.
What good pre-market engagement actually looks like
Start with the market, not your current suppliers. Use frameworks like the government's Find a Tender service, sector-specific trade associations, and SME-focused networks to identify who operates in this space — including suppliers you've never worked with. For contracts with social value or net zero dimensions, that often means looking at voluntary sector organisations, community enterprises, and smaller specialist providers who don't typically respond to public sector tenders but absolutely could.
Structure your engagement so every participant receives the same information and the same questions. Publish a prior information notice. Hold any briefing sessions at a time that works for smaller suppliers, not just the large ones with dedicated bid teams. Record what was discussed and — critically — publish a summary of the market's responses before you issue the tender documents. Transparency here isn't bureaucratic box-ticking; it's what prevents a future challenge.
Separate intelligence-gathering from specification-writing
This is the discipline most teams find difficult. Pre-market engagement should inform your thinking, not outsource it. When a supplier tells you a particular technical approach is industry standard, verify that independently. When they tell you a certain contract duration is necessary for investment to be viable, stress-test that assumption with other market participants.
The specification must be written by your team, based on your requirements. Suppliers can help you understand what's achievable and at what cost. They shouldn't be drafting the output specification or the evaluation criteria. If you find yourself cutting and pasting from a supplier's briefing document, stop.
Document everything, and I mean everything
Under the Procurement Act 2023, the transparency obligations around procurement decisions are materially stronger than they were under the old PCR 2015 regime. If your pre-market engagement later becomes the subject of a challenge — and in contested markets, it might — you need a clear record showing that engagement was open, structured, and that the resulting procurement documents weren't shaped by any single market participant.
Keep notes of every meeting. Log who attended every session. Record how responses influenced (or didn't influence) your requirements. This isn't paranoia; it's the paper trail that defends a good process.
The SME dimension
One of the most consistent findings from supplier development work is that SMEs disengage early — often before a tender is even published — because they see a process already shaped around larger competitors. Effective pre-market engagement actively counters this. It signals that the buyer is genuinely open to different delivery models. It gives smaller suppliers enough advance notice to consider whether a consortium or subcontracting arrangement might work. It allows you to identify whether your contract packaging is creating barriers that have nothing to do with actual capability.
If your pre-market engagement isn't reaching SMEs, it isn't reaching your whole market.
The practical takeaway
Before your next significant procurement, map the full supplier landscape — not just your usual contacts. Publish a prior information notice. Run structured, documented engagement sessions open to any interested supplier. Write your specification after the engagement, not during it. And publish a summary of what you heard. That sequence won't guarantee the best tender responses, but skipping any part of it will almost certainly guarantee worse ones.
