UK Public Sector Procurement: A Bigger Opportunity for SMEs Than Many Expect

For many SMEs, public sector procurement still feels like a closed shop: too much paperwork, too many larger competitors and too little chance of success.

That concern is understandable. Tendering takes time, and a poorly chosen bid can absorb days of internal effort. But the size of the market, the recent changes to procurement rules and the data on competition all point to a more balanced picture.

Public procurement is not easy. It is still competitive, detailed and evidence-led. The opportunity is that many capable suppliers rule themselves out too early, while buyers are under growing pressure to improve access, value for money and transparency.

The numbers behind the opportunity

A few figures are worth keeping in mind before dismissing public sector work as unrealistic:

Figure	Why it matters
£434bn	Gross UK public sector procurement spending in 2024/25, according to the House of Commons Library. This shows the scale of the market available across goods, works and services.
24 February 2025	The date the Procurement Act 2023 came into force, changing the rules that shape how public bodies buy from suppliers.
20%	The National Audit Office found that 20% of large contracts using open competition between January 2021 and January 2023 received only one bid.
21% to 16%	Open Contracting Partnership analysis suggests single-bid lots in above-threshold open and competitive flexible procedures fell from around 21% as the new regime came in to around 16% one year later.
7%	The same Open Contracting Partnership analysis noted that single-bid tenders tend to be approximately 7% more expensive than tenders with more than one bid.
10%	For relevant central government procurements, social value should carry a minimum weighting of 10% of the total score under PPN 06/20.

These figures do not mean that every tender is lightly contested. They do not mean that a weak answer will win. What they do show is that public sector procurement is large, active and more open to credible suppliers than many SMEs assume.

Competition is real, but it is not always as crowded as it looks

One of the biggest misconceptions about public sector bidding is that every contract attracts a long list of polished, well-resourced competitors. Some do. Many do not.

The National Audit Office’s findings on single-bid open competitions should be read carefully. A single-bid tender is not automatically an easy tender. It may reflect a difficult specification, limited supplier awareness, a framework route that narrows the field or a market where suppliers are already busy. But for an SME with relevant experience, it also suggests that some opportunities are missed simply because suitable businesses do not bid.

That is why opportunity selection matters. The best starting point is not “which tenders are live this week?” It is “where can we evidence delivery, control risk and offer a clear advantage?”

Where SMEs often lose marks

Most unsuccessful bids do not fail because the supplier is unsuitable. They fail because the submission does not give the evaluator enough confidence.

Common problems include:

Generic responses that could apply to any contract.
Too much background about the company and not enough about delivery.
Claims that are not backed up with evidence.
Weak examples of previous work.
Social value responses that read like copy-and-paste CSR statements; and
Method statements that explain what will happen, but not how it will be managed, measured and reported.

A good bid is not a brochure. It is a controlled argument. Every section should help the evaluator answer one question: can this supplier deliver what we need, with the least risk and the best overall value?

Social value can carry real weight

Social value is no longer a short paragraph at the end of a bid. In relevant central government procurements, it should carry a minimum 10% weighting. Local authorities, NHS bodies and other public sector buyers may also build social value into their scoring, often with priorities linked to local employment, skills, carbon reduction, supply chain resilience or community benefit.

This is where many SMEs undersell themselves. They may already create local jobs, train people, support apprenticeships, reduce waste or use regional supply chains, but they describe those contributions in vague terms.

A stronger social value answer is specific to the contract and the buyer. Before writing it, look at the buyer’s corporate plan, local priorities, climate commitments and employment challenges. Then set out what you will do, how you will measure it and who will be responsible for delivery.

For example, instead of saying “we support local communities”, a stronger answer might explain how many local apprenticeships, work placements, supplier opportunities or carbon-reduction measures will be delivered during the contract period.

Frameworks, DPS opportunities and dynamic markets can create a route in

Traditional frameworks can be difficult for new suppliers because, once a framework has closed, there may be no route on until the next procurement cycle.

Dynamic markets, introduced under the Procurement Act 2023, are designed differently. Government guidance describes a dynamic market as a list of qualified suppliers who have met the conditions for membership and are eligible to participate in future procurements.

For SMEs, this matters because the first public sector win is often the hardest. A well-chosen framework, DPS or dynamic market can help a business build public sector experience, create buyer confidence and develop a stronger evidence base for future tenders.

The important point is selectivity. Not every framework is worth joining. Before committing time, suppliers should check whether buyers in their target market are using it, what evidence is needed to be accepted, how call-off opportunities are issued and whether the likely contract values justify the effort.

What a more competitive bid looks like

A stronger bid usually starts before the tender is live. Businesses that perform well tend to have the basics ready: case studies, policies, accreditations, CVs, delivery processes, risk controls and social value commitments that can be adapted quickly and credibly.

If you are considering public sector work, focus on five practical steps.

Choose the right opportunities. Do not chase every tender. Prioritise contracts where you can evidence similar work, meet the requirements and offer a credible delivery model.

Read the scoring criteria before you write. The weighting tells you where to spend your time. A 30% quality question deserves more attention than a low-weighted compliance answer.

Answer the question directly. Evaluators should not have to search for the point. Use the buyer’s language, follow the structure of the question and make each answer easy to score.

Evidence every major claim. If you say you reduce risk, improve mobilisation, deliver social value or manage quality, prove it with a relevant example or measurable result.

Review the bid as an evaluator would. Before submission, check whether each answer gives the buyer confidence, addresses risk and shows why your approach is a good fit for this contract.
