Public sector bids are marked against a published scheme by evaluators who have to justify every score. Write for that reader and you will beat better companies who didn't.
Most losing bids are not from worse companies. They are from companies that wrote a brochure when they were asked a question, and were marked accordingly by an evaluator with a scoring rubric and no discretion to be generous.
Public tenders publish their evaluation methodology. Read it before you write a word. You are looking for:
Read the descriptor for full marks and treat it as a specification. If a 5 requires “a comprehensive response with relevant evidence and clear added value”, then your answer needs those three things explicitly. Evaluators justify scores against those words.
The most common and most expensive failure. If the question asks how you will mobilise the contract in the first 30 days, every sentence should be about the first 30 days. Company history, awards, and your values do not score against that question and consume the word count you needed.
A reliable structure:
“We have extensive experience delivering similar contracts” scores poorly. “We have delivered the same service for Rochdale Borough Council since 2021 across 42 sites, achieving 99.2% against the KPI for response times, verified in their annual review” scores well.
The pattern: named client, scale, duration, measured outcome. If you cannot name the client for confidentiality reasons, say “a metropolitan borough council in Greater Manchester” and keep the numbers.
The person marking your bid is reading eight submissions to the same question, often on a Friday afternoon, and must record a defensible score. Make it easy:
These are pass/fail and they are the reason a serious proportion of bids never get evaluated:
Build a compliance checklist from the instructions to tenderers on day one, and have someone who did not write the bid check it before submission.
Where price is scored on a formula — commonly lowest price gets full marks, others scored proportionally — work out what a given price difference is actually worth in marks. Sometimes being 5% more expensive costs you two points and your quality advantage is worth six. Sometimes the formula is brutal and price dominates. The methodology tells you which, and it should shape your pricing decision rather than being discovered afterwards.
Buyers must tell unsuccessful bidders their scores and the characteristics of the winning bid. Ask for a full debrief every time, win or lose. Over a handful of bids you will see exactly which questions you consistently underscore — and that is a far better guide to improving your win rate than any general advice, including this.
