How to win public sector contracts
Published 30 October 2026
To win public sector contracts, bid for fewer, better-matched tenders and answer exactly what the buyer scores. Under the Procurement Act 2023, a competitively tendered contract goes to the most advantageous tender, which doesn't mean the lowest price has to win. Check the pass or fail conditions first, back every answer with evidence, and learn from each assessment summary.
Small businesses win public sector contracts all the time. In Contracts Finder awards published between 1 July and 28 October 2026, buyers marked the winner as small or medium-sized in 46% of construction awards and 56% of training awards. Winning is less about luck than about choosing the right tenders and answering exactly what the buyer scores. This guide covers how buyers decide and what you can do at each step.

How do buyers decide who wins?
Under the Procurement Act 2023, a contract awarded through a competitive tendering procedure goes to the "most advantageous tender". That's the tender that meets the buyer's requirements and best satisfies the award criteria, assessed using the method the buyer set out (section 19). Government guidance says this doesn't mean the lowest price has to win.
The buyer must describe how tenders will be assessed and, where there's more than one criterion, show how important each one is, for example as a percentage weighting (section 23). So the scoring is published before you write a word. Read it first.
What does the scoring usually look like?
We read the award criteria in new Find a Tender notices published between 1 September and 28 October 2026. Of 3,060 procurements, 2,264 listed award criteria in the published data.
- Price matters, but rarely on its own. Of 1,692 notices that gave price or cost a percentage weighting, the median weighting was 40%. Most of the marks went on quality and other criteria.
- Social value comes up often. 678 of the 2,264 (30%) had a criterion named social value. Where it had a percentage weighting, the median was 10%.
Weightings vary by buyer and contract, so always check the documents for the tender in front of you.
How do I pick tenders I can win?
The quickest way to raise your win rate is to bid for fewer, better-matched tenders.
- Check the pass or fail conditions first. A buyer must disregard a tender from a supplier that doesn't meet the conditions of participation, such as legal and financial capacity or technical ability, so check these before anything else.
- Match the size and place. Look for contracts you could deliver comfortably, in areas you already work.
- Expect competition. In our count of Find a Tender award notices from the same period, lots awarded through an open procedure had a median of 6 bids. A well-chosen, well-evidenced bid has a real chance, but you won't be the only one.
- Look ahead. Award notices show who won and when contracts end. Planned procurement and preliminary market engagement notices give you time to prepare and to ask questions before the tender opens.
What should I get ready before a tender opens?
- Register on the Central Digital Platform. It's free. Since 1 April 2026, the winner of a notifiable below-threshold contract has to be registered and give the buyer its unique identifier before the buyer publishes the contract details.
- Keep your evidence in one place: insurance certificates, accreditations, policies, and two or three short case studies with dates and results.
- Know the rules for smaller contracts. For below-threshold contracts, buyers generally can't run a separate pre-qualification stage before tenders. The exception is some larger works contracts. Our guide to finding construction tenders covers where to look in that sector.
How do I answer the question that's scored?
- Map every answer to the criteria. If a question is worth 20% and asks about mobilisation, spend your words on mobilisation, not on your company history.
- Use evidence, not adjectives. Name the contract, the date, what you did and what changed.
- Follow the instructions exactly. A buyer may disregard a tender that breaks a procedural requirement in the tender documents, such as a word limit, a format or a deadline.
- Treat social value as a real question. Offer specific commitments you can deliver for this contract, because what you promise can end up in the contract.
How should I price my bid?
In our count, the median price weighting was 40%, so a lower price won't always make up for a weak quality score. Cost the work properly. If a buyer thinks a price is abnormally low, it must tell you and give you a reasonable chance to show you can deliver for that price before it can reject the tender on that ground.
How do I learn from every result?
Under section 50 of the Act, before publishing a contract award notice for a competitively tendered contract, the buyer must give each supplier whose tender was assessed an assessment summary. It covers how the buyer assessed your tender and, if different, the winning one. Read yours closely, win or lose. Only 5% of small businesses told the Federation of Small Businesses (FSB) that they receive comprehensive, actionable feedback (FSB, 15 December 2025), so this summary is worth having. Note what cost you marks and fix it before your next bid. Our guide to why tender bids get rejected covers the most common reasons.
Once you've won, most public contracts carry an implied term that the buyer pays a valid, undisputed invoice within 30 days (section 68).
Questions
What does "most advantageous tender" mean?
Under the Procurement Act 2023, a contract awarded through a competitive tendering procedure goes to the most advantageous tender. That's the tender that meets the buyer's requirements and best satisfies the award criteria, assessed using the method the buyer set out (section 19). Government guidance says this doesn't mean the lowest price has to win.
How do buyers score tenders?
The buyer must describe how tenders will be assessed and, where there's more than one criterion, show how important each one is, for example as a percentage weighting (section 23). In our count of new Find a Tender notices from 1 September to 28 October 2026, the median price weighting was 40%, so most of the marks usually went on quality and other criteria. Check the documents for each tender.
How do I bid for government contracts as a small business?
