Public sector procurement can look like a huge opportunity for SMEs. It is a large, active market, with thousands of buyers purchasing goods, works and services every year. But for smaller suppliers, the question has never really been whether the opportunity exists. It’s knowing which parts of it are actually worth pursuing.
SME public sector contracts are not spread evenly across the market. Some buyers and sectors are clearly more accessible than others. For small and medium-sized businesses, a more focused approach can mean fewer wasted bids, stronger submissions and a better chance of building a sustainable public sector pipeline.
Public Sector Spend on SMEs Is Rising
The overall picture is encouraging. Direct public sector procurement spend with SMEs reached a six-year high in 2025, according to the latest British Chambers of Commerce and Tussell SME Procurement Tracker. SMEs accounted for 21% of all direct public sector spend, worth £45.2 billion. That's up from 19% in 2024 and above the running average of 18% since 2020.
The wider market context reinforces the scale of the opportunity. Gross UK public sector procurement spending reached £434 billion in 2024/25, which means even a modest share of the market can represent a meaningful growth opportunity for SMEs.
The detail matters, though. The strongest opportunities are not necessarily found by chasing the biggest contracts or the most familiar buyers. They come from understanding where SMEs are already gaining traction, and where your business has a realistic route to compete.
Local Government: Leading the Way
Local government is currently one of the strongest areas for SME public sector spend. In 2025, local government in England spent £29.1 billion directly with SMEs, with the highest SME share of spend at 34%. That percentage has grown consistently since 2020.
Local authorities often buy services that rely on local knowledge, regional coverage, fast response times and close stakeholder relationships. Contract values can also be more proportionate to SME capacity than large central government programmes, although this will vary by category.
For many SMEs, local government is a practical starting point. Relevant areas might include:
- facilities management and maintenance
- grounds maintenance and environmental services
- training and workforce development
- social care and community services
- transport and logistics
- minor works and construction support
- professional services
- IT support and digital services
- recruitment and temporary staffing
Local authorities still need robust evidence, value for money and compliant procurement routes. But the data suggests this is a part of the public sector where smaller suppliers are already winning meaningful work.
Central Government: Targets and Barriers
Central government is more complicated. The same SME Procurement Tracker found that central government’s share of direct SME spend was 10% in 2025. While that represents £6.4 billion spent directly with SMEs, performance still ran 8.4 percentage points below new SME procurement spending targets on average.
There is now more pressure to improve. Under PPN 001 on SME and VCSE procurement spend targets, in-scope central government organisations must a three-year target for direct spend with SMEs to be achieved in the financial year ending March 2028. The Procurement Act 2023 also introduced wider reforms intended to reduce barriers for smaller suppliers, improve transparency around upcoming opportunities, support early market engagement and extend 30-day payment terms through the supply chain.
For SMEs, this creates a mixed picture. On the one hand, there is policy pressure to improve access. On the other, central government contracts can be larger, more complex and more dependent on established frameworks, incumbent suppliers and national delivery capacity.
That does not mean central government should be written off. It means SMEs need to choose their route carefully. In some cases, bidding as a prime supplier will make sense. In others, subcontracting, consortium bidding, specialist lots or framework routes will be more realistic.
NHS: Stable Market, Varied Routes
The NHS is another significant market, but it should not be treated as one single buyer. The BCC and Tussell data found that the NHS share of SME spend was 16% in 2025 and broadly flat compared with 2020. That suggests a stable but not rapidly expanding market.
NHS opportunities vary considerably depending on the type of supplier. A health tech company, estates contractor, workforce provider, training organisation or specialist consultancy will each face different routes to market: some through national frameworks, others shaped by local system priorities or healthcare-specific procurement rules.
The NHS can be attractive where an SME has a clear specialist offer, strong evidence and a practical route into the right part of the system. It’s harder to navigate without a solid understanding of the relevant buyer, route, compliance requirements and what evidence buyers actually expect to see.
Which Sectors Look More SME-Friendly?
Sector differences are just as important as buyer type. The BCC and Tussell tracker found that SMEs received 33% of direct spend in education, training and recruitment. In defence and aerospace, the figure was just 3%.
Some sectors naturally create more accessible entry points for smaller suppliers. Others are dominated by large primes, complex supply chains, high compliance requirements or major national contracts that rarely come to open market.
More accessible areas tend to include:
- education and training
- recruitment
- local operational services
- professional services
- specialist digital support
- community services
- sustainability services
- facilities support
These are not guaranteed wins, but they often provide clearer entry points for suppliers with a focused offer and good evidence.
Defence, major infrastructure, large outsourcing and national technology transformation tend to be harder sectors for small businesses. They may still hold value for SMEs, but usually through different routes: as a specialist partner, subcontractor or framework-approved supplier rather than leading every bid directly.
The better question is not “Can SMEs win here?” It’s “What route gives this SME the best chance of winning here?”
Direct Bidder, Subcontractor or Framework Supplier?
One of the biggest strategic decisions for SMEs is how to enter the market.
Direct bidding works well when the contract is proportionate to the size, experience and delivery capacity of the business. This is often the right route when the SME can show relevant evidence, manage mobilisation and compete on both quality and price.
Subcontracting can be a better route where the end contract is too large or complex to lead. It can help an SME build public sector experience, access larger programmes and work with established prime contractors. The risk is that the supplier may have less control over buyer relationships, margins and future positioning.
Frameworks can also be powerful, but only when they are chosen carefully. The right agreement can reduce barriers and give buyers a compliant route to purchase. The wrong one absorbs bid time and generates little activity. Our framework agreement consultancy helps suppliers assess which agreements fit their market, capacity and growth plans before committing resource to an application.
Consortia and partnerships are also worth considering early, particularly where a contract requires wider coverage, additional accreditations or complementary expertise. This is not a last-minute fix; it needs to be built into the bid strategy from the outset.
How SMEs Should Choose Where to Bid
Most SMEs cannot afford to chase every opportunity. Bid time is limited, and each submission needs proper attention.
A simple bid-fit review can help suppliers focus on the opportunities with the best chance of success. Key factors include:
- Buyer type: local authority, NHS, central government, education, housing or blue light.
- Contract size: realistic for turnover, capacity and financial risk.
- Geography: local, regional or national delivery requirements.
- Evidence: relevant experience, case studies and measurable outcomes.
- Route to market: open tender, framework, dynamic market or subcontracting.
- Competition: large incumbents, specialist SMEs or a mixed supplier base.
- Mobilisation: staffing, cash flow, systems and delivery readiness.
- Repeatability: whether the opportunity supports longer-term public sector growth.
This is where a structured bid/no-bid decision matrix can be useful. It helps SMEs avoid emotional decisions and focus on evidence, fit and realistic win probability. The aim is not to bid less for the sake of it. It is to bid better, with sharper targeting and more confidence in each submission.
How to Find SME-Friendly Opportunities
Finding the right opportunities means looking beyond one tender alert. Live tender searches matter, but SMEs should also review awarded contracts, framework activity, buyer pipelines, upcoming renewal dates and incumbent supplier relationships. If you’re not yet familiar with the core procurement landscape, our introduction to public sector tenders covers the essentials.
Thornton & Lowe’s Tender Pipeline supports suppliers with live tender alerts, awarded tender searches, competitor monitoring and buyer insight. For SMEs, this can help turn public sector bidding from a reactive process into a more focused growth activity.
Useful sources of opportunity insight include:
- Find a Tender and Contracts Finder (live tender portals)
- awarded contract notices
- local authority forward plans
- framework portals
- early market engagement notices
- competitor contract history
- buyer procurement pages
- sector-specific alerts
The strongest suppliers are not just waiting for opportunities to appear. They are learning where buyers spend, when contracts renew and how their offer fits before the tender is released.
How to Improve Your Chances Once You Find the Right Opportunity
Finding a good opportunity is only the first step. The bid still needs to convince the evaluator.
SMEs sometimes try to sound bigger than they are. This tends to weaken the response. Buyers do not always need the largest supplier; they need confidence that the supplier can deliver the requirement. A strong SME bid should make the most of the advantages smaller businesses can offer: flexibility, senior involvement, local knowledge, specialist expertise, faster decision-making and closer client relationships.
At the same time, the bid must address buyer concerns directly. These typically include capacity, resilience, mobilisation, financial stability, compliance, reporting and continuity. Glossing over them does not make them disappear.
Strong SME responses tend to be:
- clear about delivery capacity
- specific about relevant experience
- realistic on mobilisation
- evidence-led rather than claim-led
- honest about risk and mitigation
- measurable on social value
- disciplined on pricing
- tailored to the buyer’s objectives
Our bid writing support helps SMEs turn their experience into stronger tender responses, with clear evidence, compliant answers and a strategy that reflects the buyer’s priorities.
Common SME Concerns
Are public sector contracts too large for SMEs?
Some are, but many are not. Local government, education, training, recruitment, professional services and community-facing services can offer more proportionate routes. The key is assessing contract size, delivery risk and evidence fit before committing to a bid.
Should SMEs avoid central government contracts?
Not necessarily. Central government can still offer genuine value — particularly through specialist lots, frameworks or subcontracting routes. The better approach is to be selective and realistic about which route gives your business the best chance.
Do SMEs need public sector experience before bidding?
Relevant experience helps, but it’s not always a hard requirement. Strong private sector track records can carry weight if they’re framed around the outcomes public sector buyers care about: service quality, compliance, value for money, social value and risk management.
Should SMEs bid for everything to build experience?
No. Poor-fit bids waste resource and can erode momentum. A selective, evidence-led approach, supported by clear qualification criteria and good buyer research, tends to produce better results over time.
How Thornton & Lowe Can Help SMEs Win Public Sector Work
SMEs are winning public sector work, but the best opportunities are not evenly spread. Local government offers a strong starting point for many suppliers. Central government often requires a more strategic route. The NHS and specialist sectors reward suppliers who understand the buyer, the route and the evidence standard before they start writing.
The most important shift for most SMEs is not bidding more. It’s targeting better opportunities and making each submission count.
Thornton & Lowe helps SMEs identify realistic opportunities, assess bid fit and produce stronger submissions. We support opportunity monitoring, framework advice, bid strategy, evidence development, bid writing and tender review.
