How to write a winning tender response

By James Rehman, founder of Bidwhistle · Last checked 28 September 2026 · About 9 minutes to read

A public sector tender is not won by the best company. It is won by the best response: the one that scores highest against criteria the buyer has already published. That is good news for small businesses. You do not need a big bid team or a famous name. You need to read the tender carefully, answer exactly what is asked, and prove every claim you make.

This guide walks through how to do that, from the moment you open a tender pack to the moment you get your result.

1. Decide whether to bid before you write a word

Writing a good response takes days, sometimes weeks. Before you start, check four things:

• Can you meet every pass or fail requirement? Insurance levels, accreditations, turnover, experience of similar contracts. If one is a hard no, stop here.
• Can you deliver the contract as described, at the volume, in the places and to the timescale the buyer needs?
• Can you win on the scoring? If price carries most of the weight and you cannot compete on price, think hard.
• Do you have the time to write it properly before the deadline, alongside running your business?

Saying no to the wrong tender is what frees you to write a strong response to the right one.

2. Read the tender pack the way an evaluator will

Everything you need to score well is written down somewhere in the pack. Before drafting anything, find and note:

• The award criteria and how much each is worth. Under the Procurement Act 2023, the buyer must publish the criteria, how each will be assessed and how important each is, before you write. Importance may be given as percentages, a ranking or a description.
• The scoring scale. Most buyers describe what each score means, for example what separates a "good" answer from an "excellent" one. That description is your brief.
• Word or page limits, font and format rules, and what attachments are allowed. Evaluators are often told to stop reading at the limit.
• The deadline for clarification questions, which is usually well before the submission deadline.

Then make one table, often called a compliance matrix: every question, every requirement inside it, its weighting and its limit. You will use it to plan, to write and to check.

3. Answer the question that is asked

The most common way to lose marks is to write a good answer to a different question. Evaluators score what is in front of them against the published criteria. They cannot give credit for something the question did not ask for, and they will not go looking for an answer hidden in the wrong place.

• Break each question into its parts. A question asking how you will "mobilise, manage and report" has three parts. Give each its own heading, in the same order and using the same words.
• Treat every answer as standalone. Answers are often scored separately, sometimes by different people. Do not write "see our answer to question 3".
• Use the buyer's language, not your internal jargon. If they say "service users", do not switch to "clients".

4. Prove it, do not just claim it

"We are committed to quality" scores nothing, because every bidder can write it. What scores is evidence the evaluator can believe. For each part of an answer, cover four things:

1. What you will do, as a clear commitment.
2. How you will do it: the method, the people, the timings.
3. Proof that you can: a similar contract you have delivered, with numbers; a named accreditation; a named person's relevant experience.
4. What the buyer gets as a result: the benefit to them and to the people they serve.

Small businesses often undersell their evidence. A local contract delivered on time, a customer who renewed, a manager with fifteen years in the sector: these are exactly the specifics evaluators look for. Keep a library of them so you are not starting from scratch each time.

5. Write for a busy evaluator

Your response may be one of dozens someone is scoring that week. Make the marks easy to find:

• Short sentences and plain English. Explain any term a non-specialist might not know.
• Headings that mirror the question, and lists where the format allows them.
• Numbers instead of adjectives: "we answer calls within 20 seconds", not "we respond quickly".
• No sales language. Evaluators score substance, and superlatives read as padding.

6. Treat social value as a scored question

Many UK public contracts score social value: what your business will do, through this contract, for the local community, the environment or the economy. Central government buyers must give it at least 10% of the score on contracts above the thresholds, and from 1 January 2027 at least 20% on contracts of £5 million or more.

Generic promises score poorly here too. Make specific, measurable commitments that relate to the contract itself, for example a number of local hires or apprenticeships, a share of spending with local small businesses, or a measured cut in delivery emissions, and say how you will report on them.

7. Make your price and your method tell the same story

Price is usually scored separately, but it should pay for what you have promised. If your method describes a dedicated manager and weekend cover, your price has to fund them. A gap between the two looks like a risk, and a price that looks too low for the work may be questioned rather than rewarded. Pricing will have a guide of its own.

8. Check everything before you submit

• Go back through your table: is every requirement answered, within every limit?
• Ask someone who did not write it to read it against the question and the scoring scale.
• Check every attachment is included, named as asked and in the right format.
• Submit early. Online portals close at the exact minute, and a late response is normally rejected however good it is. Uploads can take longer than you expect.

9. After the result, win or lose

Under the Procurement Act 2023, every bidder whose tender was assessed receives an assessment summary before the award is announced: your score on each criterion, the reasons, and how the winning tender scored. For most contracts an 8-working-day standstill follows the award notice before the contract is signed.

Read your summary question by question. It shows exactly where you gained and lost marks, and it is the fastest way to improve your next response. Using feedback will have a guide of its own.
