The evidence you need before you bid, not after you find the tender

The most frustrating way to lose a public contract is to be excluded from it before anyone reads what you wrote. It happens constantly, and almost always for the same reason: a requirement that takes weeks to satisfy, discovered on a tender with ten days to run.

Insurances, at the levels buyers ask for

Public contracts specify minimum cover, and the levels are often higher than a small business carries by default. The usual set is employer's liability, public liability, professional indemnity where you give advice or design, and product liability where relevant. Some contracts also require motor fleet or contractors' all-risks cover.

You do not need to hold the highest level speculatively. You do need to know what you currently hold, what a typical contract in your market asks for, and how quickly your broker can increase cover — because "we will obtain it on award" is acceptable to some buyers and not to others, and you want to know which before the deadline.

Certifications and schemes

Which of these matter depends entirely on your sector, and the point is to find out which apply to your market before you need them:

• Quality and environmental management — ISO 9001 and ISO 14001 are frequently asked for, sometimes as "or equivalent", which is worth reading carefully because an equivalent you can evidence is cheaper than certification.
• Health and safety — ISO 45001, or membership of a recognised assessment scheme, particularly for construction, maintenance and facilities work.
• Cyber security — Cyber Essentials or Cyber Essentials Plus, now common wherever you will handle buyer data.
• Sector schemes — construction and works suppliers are routinely asked for a recognised pre-qualification or safety scheme membership.
• Data protection — registration with the regulator where you process personal data, and a policy you can actually produce.

Certification takes weeks to months. Every one of these is cheap to start early and impossible to start late.

Financial standing

Buyers test whether you can carry the contract. That usually means recent accounts, sometimes a minimum turnover — commonly expressed as a multiple of the annual contract value — and occasionally a credit check or a parent company guarantee. Know your own figures, and know how a buyer's credit-checking service scores you, because that is sometimes the surprise.

The evidence that is not a certificate

Alongside the paperwork, most competitions ask for things you have to have written down already: policies on health and safety, equality and diversity, environmental management, modern slavery, business continuity and data protection; named references for comparable contracts; and case studies with real figures in them.

Write these once, keep them current, and keep them where whoever assembles a bid can find them. A policy dated four years ago and signed by someone who has left is worse than none.

Do it as a project, not as a reaction

Take an afternoon, list what your target market asks for, mark what you hold, and put dates against the gaps. Then diary every expiry. The suppliers who bid comfortably are not the ones with more paperwork — they are the ones who did this once and keep it current.

"Or equivalent" is worth taking seriously

Many requirements are written as a named certification "or equivalent", and suppliers routinely read past the second half. Where certification is genuinely out of reach in the time available, an equivalent you can evidence — a documented management system, an independent audit, a client's own assessment — is sometimes accepted, and asking during the clarification window costs nothing.

Be realistic about it, though. Equivalence has to be demonstrated, not asserted, and a buyer who has written "ISO 9001 or equivalent" usually means a system that would pass an audit rather than a folder of good intentions.

Keep the evidence assembled, not just held

There is a difference between holding an accreditation and being able to produce it at four o'clock on a deadline day. Keep a single folder — certificates with expiry dates, insurance schedules showing the levels, signed and dated policies, accounts, references with current contact details, and standard company information.

Review it quarterly. The most common discovery in that review is not a missing certificate but an expired one, or a policy last signed by a director who left two years ago.

Decide what is worth buying, using your own history

Accreditations cost money and time, so treat the decision as an investment case rather than a checklist. Look back at the opportunities you declined or lost over the last year and count how many turned on a single missing requirement. If four contracts you would have bid for all required the same scheme membership, its value is now a number rather than a feeling.

The reverse is also worth knowing. An accreditation nothing in your market has asked for in two years is not a priority, however respectable it looks.
