Quick answer: Most public sector tender documents are so dense with legal language, cross-references, and qualification jargon that only well-resourced suppliers with dedicated bid teams can navigate them. That is not neutrality — it is an invisible barrier that shrinks your market and reduces competition.
The problem nobody wants to own
Ask a procurement team whether their tender documents are accessible and most will say yes. Ask the SMEs who downloaded the pack and decided not to bid, and you get a very different answer.
The gap between those two answers is where your supplier market quietly contracts.
Tender documents tend to accumulate complexity over time. Legal adds a clause after a dispute. Procurement adds a requirement after an audit finding. Finance adds a schedule nobody ever reads. Nobody ever takes anything out. After a few years you have a 140-page ITT for a £200k contract, and the only organisations with the time and resource to respond are the ones who already do this for a living.
What complexity actually selects for
When tender documents are hard to navigate, you do not get the best suppliers. You get the most experienced bidders. Those are not the same thing.
A specialist SME with exactly the right capability may look at your documentation pack, calculate that they need three days to understand it before they can write a word of response, and decide the odds are not worth it. A larger incumbent with a bid writer on the payroll submits regardless. You have just made your evaluation process a test of bid-writing infrastructure rather than service delivery capability.
This matters particularly for the categories where SME and VCSE involvement is most valuable — community services, specialist consultancy, local supply chains, anything where knowledge of place or sector is the real differentiator.
What the Procurement Act 2023 changes — and what it does not
The Procurement Act 2023 introduces a stronger expectation of transparency and market access, including the requirement to publish planned procurements via the Central Digital Platform and the new duty to consider barriers faced by SMEs and VCSEs. The intent is to open markets, not just to document them.
But the Act does not rewrite your ITT for you. If you publish a transparent pipeline and then release a document that requires a legal degree to interpret, you have met the letter of the requirement and missed the point entirely.
The Transforming Public Procurement agenda was always about outcomes, not process compliance. Accessible tender documents are part of that.
Five things that make tender documents unnecessarily hard
First: undefined acronyms and internal jargon. Your organisation knows what the JCAD, the SLA schedule, and the gateway review process mean. A supplier reading your documents for the first time does not.
Second: questions buried in schedules. Suppliers should not have to cross-reference four documents to understand what they are actually being asked to evidence.
Third: disproportionate qualification requirements. Requiring three years of audited accounts and £5m turnover for a £150k contract is not due diligence. It is market narrowing dressed up as risk management.
Four: word limits that punish clarity. Giving suppliers 500 words to answer a question that genuinely requires 800 words does not produce concise responses. It produces incomplete ones.
Fifth: no worked example or specification narrative. If a supplier cannot picture what good delivery looks like from your documents, they are guessing. The ones who guess confidently tend to be the ones who have delivered similar contracts before, which takes you back to the same shortlist.
What better looks like
The best tender documents I have seen share a few characteristics. They lead with the problem the buyer is trying to solve, not the procurement process the buyer is running. They use plain English with a short glossary for anything technical. They front-load the commercial and practical information — what is the contract, what is the value, what is the term, what are the key deliverables — so a supplier can assess fit quickly before investing time in the full pack.
They also include a genuine pre-tender information session, not a supplier day where questions are batted away, but a session where suppliers can get straight answers to practical questions. And they publish those answers to everyone, not just the suppliers who attended.
Proportionality is the other word that should be on every procurement team's wall. The documentation burden should match the contract risk and value. A cleaning contract for one building does not need the same ITT architecture as a strategic outsourcing programme.
The practical takeaway
Before your next procurement goes live, give the full document pack to someone outside your organisation — ideally a small business owner with no prior knowledge of your sector — and ask them to tell you what the contract is, what you are asking for, and what a good response looks like. If they cannot answer those three questions confidently, your documents are not ready. Revise before you publish, not after you wonder why only two organisations submitted.
