Small and medium-sized businesses win approximately 24% of central government contract value in the UK — and a higher proportion by volume, particularly below £500,000. But most SMEs find the process of finding, evaluating and winning government contracts opaque, time-consuming and inconsistent. This is a practical guide to building a public sector revenue stream.
Why government contracts are worth pursuing
- Reliable payment — government bodies typically pay on 30-day terms and are low credit risk
- Contract security — public sector contracts tend to be longer and more stable than private sector work
- Reference value — a council or NHS contract is a credible reference for further public and private sector bids
- Volume — the UK public sector spends approximately £300 billion annually on goods and services
Get the basics right first
- Appropriate Companies House registration and up-to-date accounts
- Relevant certifications — ISO 9001, Cyber Essentials, industry-specific accreditations
- Public liability and professional indemnity insurance at appropriate levels
- A written health and safety policy (required for most contracts above £10,000)
- 3 relevant case studies with measurable outcomes — the most frequently requested and most commonly weak element of SME bids
Find the right opportunities
There are 12+ UK procurement portals. Manually checking two or three of them every day is both time-consuming and unreliable. Automated monitoring matched to your CPV codes, sector and contract value range finds every relevant opportunity across all portals — often within hours of publication. A free platform such as WinAContract does exactly this, pulling Find a Tender, Contracts Finder and the devolved portals into one searchable feed. For most SMEs this doubles the number of relevant opportunities they are aware of.
Know when to bid and when to pass
A quality bid for a £250,000 contract typically costs £3,000–£6,000 in staff time. Before bidding, confirm: you meet all minimum requirements; you have a directly relevant case study; the contract value is appropriate for your size; you have delivery capacity. If you cannot answer yes to all four, pass.
Use frameworks
Framework agreements and Dynamic Purchasing Systems (DPS) are pre-approved supplier lists that public bodies can use to award contracts without a full open procurement. Getting onto the right frameworks is one of the highest-leverage activities for SMEs. Key frameworks: Crown Commercial Service agreements, sector-specific NHS and education frameworks, local authority collaborative frameworks through ESPO and YPO.
Write better bids
- Write to the evaluation criteria, not just to the questions
- Evidence every claim — evaluators cannot award marks for unsubstantiated assertions
- Use specific numbers — "we delivered X for organisation Y, achieving Z outcome"
- Address social value specifically and credibly — vague commitments score poorly
- Proofread for procurement jargon consistency — match the language the buyer uses
Drafting against the evaluation criteria is where most SME bid time disappears. AI bid-writing tools such as BidWriter generate a structured first draft mapped to each scored question, which you then refine and evidence — turning a blank page into an editable response in minutes rather than days.
