Tender Evaluation Process: How Buyers Score Your Submission (2026)
Understanding how buyers evaluate tender submissions is one of the most commercially valuable things a tendering organisation can know. Every evaluation decision follows a defined process — evaluation criteria, mark descriptors, weighted scoring, and panel consensus. Understanding that process allows you to write responses that score maximum marks at every stage.
This guide covers how the tender evaluation process works from selection questionnaire through to contract award — including what changed under the Procurement Act 2023. For the complete overview of how tendering works, see our guide to tendering for contracts.
The Most Advantageous Tender (MAT)
Public sector contracts are awarded to the Most Advantageous Tender — commonly known as MAT. This replaced the Most Economically Advantageous Tender (MEAT) standard under the Procurement Act 2023, which came into force in February 2025. Our guide to the Most Advantageous Tender covers the standard in full.
MAT requires buyers to evaluate quality, price, and social value together — not simply award to the lowest price. This approach allows buyers to select the supplier who offers the best overall value — one who is technically capable, financially sound, and able to deliver the required outcomes to the required standard at a competitive price.
The relative weighting between quality, price, and social value varies by contract type. A typical service contract might be evaluated as 60% quality, 20% social value, and 20% price. A straightforward goods supply contract might weight price more heavily. The evaluation weighting is always stated in the procurement documents. Read it before writing any response or setting any price.
Stage 1: Pre-Qualification
Many above-threshold contracts use a pre-qualification stage before issuing the full ITT. This stage — conducted through a Selection Questionnaire (SQ) — assesses whether potential suppliers are eligible to participate before they invest in a full submission.
The SQ evaluation is predominantly pass or fail. It assesses financial standing, required accreditations, mandatory insurance levels, and any other eligibility criteria defined by the buyer. Failing any mandatory criterion results in exclusion from the competition — regardless of capability.
Examples of common mandatory SQ requirements include: annual turnover above a specified threshold, current ISO certifications, minimum insurance levels, and absence from mandatory exclusion grounds (conviction of relevant offences, insolvency, serious misrepresentation). Our guide to the pre-qualification questionnaire covers what buyers assess and how to prepare effectively.
Stage 2: ITT Quality Evaluation
Organisations that pass the SQ stage receive an Invitation to Tender (ITT). The quality responses within the ITT are evaluated individually by an assessment panel against published mark descriptors.
Each question is scored on a defined scale — commonly 0 to 10 or 0 to 5. Each score level has a corresponding mark descriptor that defines what a response at that level contains. A score of 10 is not awarded simply for a well-written response. It is awarded when the response meets every criterion described in the top mark descriptor.
Understanding the mark descriptors before writing any response is essential. They tell you precisely what the evaluator needs to see to award full marks. Write to the mark descriptors — not just to the questions. Our guide to answering tender questions covers how to structure responses around evaluation criteria.
Many buyers reserve the right to exclude submissions that score below a minimum threshold on any individual quality question — typically below 5/10. A low score on one question can therefore result in exclusion from the competition regardless of strong performance elsewhere. Every quality response must be competitive — not just the ones you consider most important.
Stage 3: Price Evaluation
Price is evaluated alongside quality under the MAT framework — not in isolation. The most common price evaluation method in public sector procurement awards maximum marks to the lowest compliant price and reduces marks proportionally for higher-priced submissions.
The evaluation formula and the proportion of total marks allocated to price are stated in the procurement documents. Understanding both before setting your price is essential. Our guide to tender pricing strategy covers how to model the weighted scoring impact of different price positions and how to price sustainably across the full contract term.
Abnormally low prices are assessed carefully by buyers. A price significantly below the market rate raises concerns about delivery quality and may prompt the buyer to request a written explanation before deciding whether to accept or reject the submission.
Stage 4: Social Value Evaluation
Social value is evaluated as a distinct scored criterion — not as part of quality or price. Under the Procurement Act 2023, social value carries a minimum mandatory weighting of 10% in most public sector contracts — rising to 30% in some categories.
Social value responses are evaluated against defined themes and outcomes. The most consistently evaluated themes in 2026 are tackling economic inequality, fighting climate change, improving equal opportunities, and supporting health and wellbeing. Responses are scored against published mark descriptors — the same structure as quality responses.
Generic social value commitments score poorly. Locally specific, measurable, deliverable commitments aligned with the buyer’s published priorities score highest. Our guide to social value and tendering covers how to develop commitments that score maximum marks.
Stage 5: Panel Evaluation and Consensus
In most public sector procurement, each submission is evaluated independently by multiple panel members. Each evaluator scores the submission against the published criteria. Where scores differ significantly between evaluators, a moderation meeting is held to reach a consensus score.
This panel structure has an important implication for how you write responses. Your submission will be read by people with different backgrounds, different levels of technical expertise, and different priorities. Write for the least technical reader on the panel. Every claim should be clear and comprehensible without specialist knowledge, every acronym should be defined on first use, every technical concept should be explained in plain language.
Stage 6: Award Decision, Standstill, and Contract Signing
After evaluation is complete, the buyer notifies all suppliers of the outcome. For above-threshold contracts, a mandatory standstill period — typically eight working days — follows before the contract is signed. This period gives unsuccessful suppliers the opportunity to request a debrief and, if they have grounds, to challenge the decision.
Our guide to the standstill period covers your rights during this window. Our guide to tender debriefs covers what feedback you are entitled to and how to use it to improve subsequent submissions.
Frequently Asked Questions About Tender Evaluation
Can I find out how the evaluation panel scored my submission?
Yes — through the debrief process. You have a legal right to request feedback on your submission after any above-threshold public sector tender. The buyer must provide your scores on each evaluation criterion, the winning supplier’s scores where possible, and the reasons for the decision. Request a debrief immediately after receiving the award decision notice.
What happens if my submission scores below the minimum threshold on one quality question?
Many buyers reserve the right to exclude submissions that fall below a minimum score on individual quality questions — typically 5/10 or equivalent. If your submission is excluded on these grounds, you will be notified and the submission will not proceed to the price evaluation stage. This is why every quality response must be competitive — not just the responses to questions you consider most important.
How does the buyer decide between two submissions with similar overall scores?
Buyers define their tie-breaking approach in the procurement documents. Common approaches include awarding preference to the higher quality score where prices are equal, the lower price where quality scores are equal, or a secondary evaluation of specific criteria identified as tie-breakers. Check the procurement documents for the specific approach before submitting.
Is the tender evaluation process the same for all contract types?
No. The weighting between quality, price, and social value varies by contract type. The mark descriptors and scoring scale may differ between buyers. Some contracts use additional evaluation stages — presentations, site visits, or sample submissions — not required by others. Always read the full evaluation methodology in the procurement documents before planning any response.
What is a balanced scorecard evaluation?
A balanced scorecard is an evaluation approach that weights multiple dimensions of value — quality, price, social value, environmental performance, innovation — against strategic themes defined by the buyer. It is most commonly used for major infrastructure contracts and complex programmes. The Olympic Delivery Authority for London 2012 and HS2 used balanced scorecard approaches for major supply chain appointments. For most mainstream public sector procurement, the MAT weighted scoring approach is standard.
