How to find and win your first UK public sector contract

Last reviewed: 26 July 2026

The short answer

Winning your first UK public sector contract comes down to four steps: find the right opportunity, decide whether it is worth bidding, answer exactly what the tender asks, and evidence every claim. Higher-value opportunities are published on the Find a Tender service, which carries contracts at or above the procurement thresholds, around 139,688 pounds for central government goods and services. Lower-value work has historically appeared on Contracts Finder, where central government contracts from 12,000 pounds are advertised. Both now connect to the Central Digital Platform under the Procurement Act 2023. The hardest part is not finding contracts, it is choosing the ones you can actually win and writing a focused, evidenced response instead of a hopeful one.

Public buyers are not looking for the flashiest supplier. They are looking for a low-risk supplier who clearly meets the requirement, answers the questions in the order asked, and proves each claim with a specific example. That is a discipline any capable SME can learn, and this guide walks through it end to end.

Where to look

There are two official free sources you should know before paying for any commercial tender-alert tool.

Find a Tender

The Find a Tender service publishes higher-value public sector opportunities: those at or above the procurement thresholds. As a rough guide, the threshold for central government goods and services sits around 139,688 pounds including VAT, with higher thresholds for other authorities and for works. Set up a search that matches your sector and location, save it, and let the alerts come to you rather than checking manually.

Contracts Finder

Contracts Finder has traditionally carried lower-value opportunities, including central government contracts from 12,000 pounds, along with details of some awarded contracts. For a first-time bidder this is often the more useful of the two, because smaller contracts tend to have less incumbent competition and give you a chance to build a public sector track record before you chase larger work.

Under the Procurement Act 2023, which went live on 24 February 2025, opportunities and notices are drawn together through the Central Digital Platform. Register your organisation there early so your core details are ready to reuse, and if you want the wider context on how the new regime works, read our Procurement Act 2023 guide for SME bidders.

How to read a tender

A tender pack can run to dozens of documents, but a first read should extract six things before you write a single word:

• The buyer and the requirement. Who is buying, what do they actually need, and what is the contract value and length? This frames everything else.
• The deadline. The exact submission date, time and time zone. Public deadlines are hard cut-offs, and a portal that closes at noon does not accept a bid at 12:01.
• The award criteria and weightings. How the marks split between price, quality and social value. This tells you where to spend your effort.
• The mandatory, pass or fail requirements. Minimum standards, certifications and any exclusion questions. Miss one and the quality of your writing will not matter.
• The response format. Word or character limits, required attachments, and the exact question set. Answer in the structure the buyer gives you.
• The clarification process. How and by when you can ask questions. Good bidders use it; the answers are usually shared with all bidders.

Map the award criteria to a simple response plan before you draft. If quality is 60 percent of the score, price 30 and social value 10, your time should broadly follow those proportions. Bidders lose winnable contracts by writing at length about the things they enjoy and skimming the things that carry the marks.

SQ versus ITT

Two acronyms appear constantly, and confusing them costs first-timers time.

A Selection Questionnaire (SQ) is a pre-qualification stage. It is largely pass or fail and checks that you meet minimum standards: financial standing, relevant insurance, health and safety and quality processes, comparable past experience, and that no exclusion grounds apply to you. The SQ is about eligibility, not persuasion. Give complete, accurate, evidenced answers and do not oversell.

An Invitation to Tender (ITT) is the scored bid itself. Here your responses to quality questions, your price, and your social value offer are evaluated and marked. This is where the competition is genuinely won and where your writing quality matters.

In a multi-stage competition the SQ comes first and only shortlisted suppliers are invited to submit an ITT. In a single-stage open procedure there is no separate SQ; the selection and award questions arrive together in one submission. Always check which shape a given procurement uses, because it changes how you plan your time.

The bid or no-bid decision

The instinct of every new bidder is to bid for everything. Resist it. A disciplined bid or no-bid decision is the single highest-return habit in public sector bidding, because writing fewer, better-targeted bids wins more work than spreading thin effort across every opportunity you can find.

Before committing, score the opportunity honestly against a handful of questions:

• Fit. Do you genuinely meet the requirement and any mandatory standards, without stretching?
• Capacity. Can you both write a strong bid before the deadline and deliver the contract if you win it?
• Competition and incumbency. Is there an incumbent who is performing well? Is the specification written around them?
• Value. Is the margin and strategic value worth the cost of bidding, including your time?
• Win probability. Realistically, do you have a credible chance, or are you making up the numbers for someone else's competition?

If the honest answer to several of these is weak, walk away and put that effort into an opportunity you can win. A no-bid is not a failure; it is a decision that protects your win rate and your team's time.

Social value and PPN 002

Almost every central government tender now includes a scored social value section, governed by PPN 002. For in-scope central government contracts, social value must carry a minimum weighting of 10 percent of the total score. That is enough to decide a close competition, so it is not a section to leave until the last afternoon.

Social value asks what wider benefit your delivery of the contract will bring: local employment and skills, support for smaller businesses in your supply chain, environmental improvements, and community wellbeing. Strong answers are specific and measurable. Rather than promising to "support the local community", commit to a defined number of apprenticeships, work-experience placements or volunteering hours tied to the contract, and describe how you will evidence delivery afterwards. Buyers mark commitments they can hold you to, not good intentions.

For a full walk-through of scoring, the themes and the measurement framework, read our complete PPN 002 social value guide. It is the part of a first bid where a well-prepared SME can out-score a larger, complacent competitor.

Common first-timer mistakes

The bids we see rejected early tend to share the same avoidable errors:

1. Bidding for everything. No bid or no-bid discipline, so effort is spread too thin to win anything.
2. Not answering the question asked. Reusing generic marketing copy instead of responding to the specific question and its scoring guidance.
3. Ignoring word and character limits. Evaluators stop reading at the limit, so anything past it is wasted or, on some portals, cut off entirely.
4. Weak or generic social value. Treating a 10 percent scored section as an afterthought and losing marks a competitor banks.
5. Missing a mandatory pass or fail requirement. An expired certificate or an unanswered exclusion question ends a strong bid before evaluation.
6. No evidence. Claims without specific examples, named projects or numbers read as assertions and score low.
7. Leaving submission to the last hour. Portal upload problems are common; submit with time to spare, because a missed deadline is an automatic rejection.

Every one of these is within your control. Fixing them does not require a bigger team, only a more disciplined process.

Frequently asked questions

Where do I find UK public sector contracts?

Higher-value opportunities are on the Find a Tender service, from around 139,688 pounds for central government goods and services. Lower-value work has historically appeared on Contracts Finder, from 12,000 pounds for central government. Both connect to the Central Digital Platform under the Procurement Act 2023.

What is the difference between an SQ and an ITT?

A Selection Questionnaire is a pass or fail eligibility stage covering finance, insurance, experience and exclusion grounds. An Invitation to Tender is the scored bid, marked on quality, price and social value. Open procedures combine both into one submission.

How much does social value count?

Under PPN 002, in-scope central government contracts must apply a minimum social value weighting of 10 percent of the total score. It is scored, so it can decide a close result.

Should I bid for every contract I can find?

No. Use a bid or no-bid decision to weigh fit, capacity, incumbency, value and your realistic chance of winning. Fewer, better-targeted bids win more than thin effort spread across everything.
