The documents SMEs need before bidding for public sector contracts

Most SMEs lose their first tender before writing a word — not because the answers were weak, but because a required document did not exist. The good news is that the documents buyers ask for are remarkably consistent. Prepare them once, keep them current, and every future bid becomes faster.

Here is the full checklist, roughly in order of how often each item is required.

Insurance

Almost every public sector tender asks for evidence of insurance, usually as a pass/fail requirement:

• Employer's liability — a legal requirement for almost all employers anyway; £5m is the statutory minimum.
• Public liability — buyers commonly require £5m or £10m. Check tender requirements before renewing your policy; upgrading mid-term is usually possible.
• Professional indemnity — expected for consultancy, design, IT and professional services, typically £1m–£2m.

Keep current certificates in one folder. You will attach them to almost everything.

Core policies

Buyers expect written policies appropriate to the size of your business. A two-page policy that reflects what you actually do beats a twenty-page template you have never read. The regulars:

• Health and safety policy — legally required in writing if you have five or more employees.
• Equality, diversity and inclusion policy.
• Environmental or sustainability policy — increasingly scored, not just checked. Buyers want to see practical measures, not aspirations.
• Safeguarding policy — required for any work involving schools, care settings or vulnerable people.
• Data protection / GDPR policy — expected whenever you will handle personal data.
• Anti-bribery and modern slavery statements — often a simple declaration for smaller businesses.

Case studies

This is where most SMEs are weakest, and it is the highest-value fix on this list. Prepare two to four case studies of relevant work, each covering:

1. The client and context (anonymise if necessary).
2. What you were asked to deliver, including value and duration.
3. How you delivered it — the interesting part, and the part most businesses skip.
4. The outcome, with numbers wherever possible.
5. A client contact willing to act as a referee.

Buyers ask for "examples of similar contracts" constantly. Having these written before a tender lands turns a day of scrambling into a copy-and-tailor job. See our guide to deciding whether to bid for how evidence should shape that decision.

Financial information

Expect to provide:

• Your last one to two years of accounts (or equivalent for newer businesses).
• Annual turnover figures.
• Sometimes a credit check consent or bank reference.

If your turnover is modest, do not be put off: many contracts are deliberately sized for SMEs, and buyers must generally assess financial standing proportionately.

Accreditations and certificates

None of these are universally required, but each unlocks certain contracts:

• Constructionline, CHAS, SafeContractor — common in construction and maintenance.
• Cyber Essentials — increasingly required for any contract touching public sector data or systems.
• ISO 9001 / 14001 / 27001 — valuable in some sectors, rarely mandatory for smaller contracts. Do not buy certifications speculatively; check what the contracts you actually want require first.

Social value evidence

Since the Social Value Act and the current procurement rules, most public tenders score social value — typically 10–20% of the total marks. Start collecting evidence now: local employment, apprenticeships, community activity, environmental measures. Our guide on what social value means in a tender covers this in detail.

Keep it maintained

A readiness pack is only useful if it is current. Expired insurance certificates and out-of-date policies are among the most common — and most avoidable — reasons bids fail compliance checks. Review the pack quarterly.

Bid Sense tracks all of this automatically: your procurement readiness dashboard shows what you have, what is missing and what is about to expire, scored against the contracts you actually want to win. Join the early access list to be among the first to use it.
