What tender evaluators actually score

Two separate stages, not one

Most bidders think of tender evaluation as a single exercise. It is not. UK public procurement runs in two steps, and conflating them is one reason firms waste time on submissions they were never going to win.

The first is selection. This is pass or fail, not scored. The buyer checks insurance levels, financial standing, relevant accreditations, and track record before the quality assessment opens. Common reasons for elimination at selection include insufficient public liability cover, no Constructionline or equivalent registration, turnover below the stated minimum, or an experience requirement the firm cannot demonstrate. If you fail selection, your quality response is never read. Check the selection criteria before you invest a day in writing.

The second is award. This is where scoring happens. Quality and price are assessed separately, each given a published weighting, and combined to produce a total. The highest total wins.

How the quality score is divided

The quality section is not one question. It is a set of individual criteria, each carrying a stated allocation of marks. Together they add up to 100% of the quality score. Common criteria in UK construction and infrastructure tenders include:

• Technical methodology: your plan for doing the work, with a programme
• Health and safety: your documented approach and a relevant site example
• Social value: apprenticeships, local supply chain, community or environmental commitments
• Supply chain management: how you select, instruct and monitor subcontractors
• Quality assurance: your procedures and how they apply to this contract
• Team and experience: relevant CVs and named examples from comparable projects

The marks allocation for each criterion is stated in the tender documents. A criterion worth 30% of the quality score demands a materially stronger response than one worth 5%. Evaluators work through criteria independently: a strong methodology answer does not compensate for a weak social value answer.

Social value is a scored criterion, not an afterthought

Social value became a statutory consideration in public procurement under the Public Services (Social Value) Act 2012. Government guidance since then has made it a mandatory scored criterion in central government contracts, carrying a stated minimum weighting. Many local authorities and housing associations apply the same approach.

This means it is not marginal. A bidder who writes one paragraph about being committed to the local community will lose marks on a dedicated scored section. The answer needs to be specific: a named number of apprentices, a percentage of spend going to local supply chain, a carbon baseline and what will be reduced. Vague social value responses are one of the most consistent ways a capable firm drops marks it should not have lost.

What the score descriptors say

Most public buyers score each criterion against a named scale, typically 0 to 5 or 0 to 10, with written descriptors at each level. The language varies between buyers but the shape is consistent:

A 0 means unacceptable: the response does not address the criterion or the buyer cannot assess it. Some buyers eliminate a bid that scores 0 on any criterion, regardless of its performance elsewhere.

A low score means the criterion is addressed but the response is incomplete, generic, or unsupported. The evaluator read it and was not convinced.

A mid-range score means the response covers all parts of the question with reasonable competence. Adequate, not strong.

A full or near-full score means the response is complete, specific, and evidenced. It shows exactly how the work will be done, with named projects, real figures, or documents the evaluator can check.

A bid that scores mid-range across every criterion can lose to one that scores full marks on the two or three criteria that carry the most weight. The difference is almost never capability. It is specificity and evidence.

The quickest way to see where you lost marks

Many public buyers will provide a scored breakdown on request. Get it, and read it against the descriptors above. Most firms find they addressed the right topics but fell short on evidence, or missed a sub-part of a criterion the evaluator was expecting.

If you want a faster read on a live bid, the Bid Audit does exactly that: we score your bid against evaluation criteria, return it with line-by-line notes on the weakest sections, and identify the three changes that would lift the score most. It costs £300 and comes back within three working days.
