Why tender bids get rejected

Published 30 October 2026

Tender bids get rejected in two ways. Some are disregarded before scoring, usually for a missed pass/fail condition, a late or incomplete submission, or ignored instructions. Others are valid but score lower than the winner, often for not answering the question asked, promises without proof, or bidding for the wrong contract. You can check for each before you submit.

Small businesses told the Federation of Small Businesses (FSB) that a bid takes on average five days to prepare, and that only 5% receive comprehensive, actionable feedback (FSB, 15 December 2025). Losing is part of tendering. Being thrown out on a technicality, or scoring badly on something fixable, is the part you can do something about.

There are two kinds of "rejected": the buyer disregards your bid without scoring it, or it is scored and loses. Here are the usual reasons for each.

Why are bids disregarded before scoring?

Under section 19 of the Procurement Act 2023, a buyer must disregard a tender from a supplier that doesn't meet the conditions of participation. It may disregard a tender that breaks a procedural requirement in the tender notice or documents, for example by arriving late, leaving out information that was asked for, or not following the required format. The common causes:

1. Missing a pass/fail condition. Insurance below the level asked for, no required accreditation, turnover under a minimum, or no reference for similar work. Read every pass/fail item before you start writing.
2. Late or incomplete submission. E-tendering portals close on the minute. Upload early, and check every attachment has gone through and opens.
3. Ignoring instructions. Word limits, page limits, fonts, file types, the order of documents, pricing schedules filled in the wrong way. Evaluators may stop reading at the limit.
4. Exclusion grounds. Certain convictions, insolvency, or serious past failures on contracts can mean a supplier is excluded (sections 26 and 28 of the Act cover mandatory and discretionary exclusion). Answer these declarations honestly; a false declaration is itself a problem.
5. A price that looks too low. A buyer may disregard an abnormally low price, but only after telling you and giving you a chance to explain it. Make sure your price is one you can actually deliver and justify.

Why do valid bids score badly and lose?

Many bids that lose were perfectly valid. They simply scored lower on quality, price or social value than the winner. Common reasons:

• Not answering the question asked. Evaluators mark against the question and the published criteria. Use the buyer's own headings and words, and cover every part of the question.
• Promises without proof. "We pride ourselves on quality" scores little. A real example does better: who the client was, when, what you did, and the result.
• Copy-and-paste answers. The FSB found 35% of small businesses repeatedly submit the same information. Reusing facts is fine; reusing whole answers that don't mention this buyer's site, people or risks isn't.
• Thin method statements. Say exactly how you would run this job: who does what, the programme, how you manage health and safety on that site, and what happens if something goes wrong.
• Ignoring social value and carbon. Public buyers often score social value, such as local jobs, apprenticeships or local suppliers. Put real, measurable commitments in your answer.
• Bidding for the wrong contract. Too big, too far away, or a buyer with a long-standing supplier. The best way to avoid losing is to be choosy about what you bid for. The FSB found 62% of small businesses find suitable contracts difficult to find.

How should I use the feedback I'm given?

For larger procurements under the Act, a buyer must give each supplier that submitted an assessed tender an assessment summary (section 50), with information about how your bid was assessed and, if different, how the winning bid was assessed. Read it line by line, note where you lost marks, and fix those answers before your next bid. For smaller contracts, it is still worth asking the buyer politely for feedback.

What should I check before I submit?

• Every pass/fail condition is met and the evidence is attached.
• Every question is answered in full, within the limits, with at least one real example.
• The price is complete, in the format asked, and one you can deliver.
• Social value commitments are specific and measurable.
• Everything is uploaded, opened and checked well before the deadline.
