Most Advantageous Tender (MAT): How Evaluation Works and How to Win
The Most Advantageous Tender — known as MAT — is the evaluation framework that governs how buyers award public sector contracts in the UK. Under MAT, buyers assess the full range of value a supplier offers — quality, price, social value, innovation and sustainability — rather than selecting the lowest price alone. Understanding how MAT evaluation works is one of the most practically valuable things any tendering supplier can do. It reveals exactly what buyers are scoring, why quality investment outperforms price competition in most competitive fields and how to structure your bid to earn the highest possible score across every evaluation dimension. This guide gives you that understanding in full.

What Is the Most Advantageous Tender?
The Most Advantageous Tender is the procurement standard introduced under the Procurement Act 2023, which came into force in February 2025. It replaces the older Most Economically Advantageous Tender (MEAT) standard, which governed public procurement under the previous regulatory framework. While MEAT remains widely referenced in procurement literature — and you may still encounter it in older tender documents and frameworks — MAT is now the correct terminology for contracts issued under the Procurement Act 2023.
The practical difference between MEAT and MAT is one of emphasis rather than fundamental principle. Both frameworks require buyers to assess overall value rather than price alone. MAT goes further in explicitly broadening what counts as value — placing greater emphasis on social value, environmental impact, innovation and the long-term public benefit of procurement decisions. The result is an evaluation environment where the quality of your written responses, the depth of your social value commitments and the credibility of your delivery model carry more collective weight than ever before.
For suppliers, this evolution is an opportunity. It means that a well-written, evidence-led, buyer-specific bid that demonstrates strong social value and credible delivery methodology can consistently outperform a cheaper competitor who offers less on every dimension except price. That is precisely the competitive environment in which expert bid writing produces its greatest return on investment.
How MAT Evaluation Works in Practice
MAT evaluation works by assigning a numerical score to each submission across multiple evaluation dimensions — quality, price and social value being the three most common. Each dimension carries a percentage weighting that reflects how much of the total score it contributes. The supplier with the highest combined score across all weighted dimensions wins the contract.
The evaluation process is structured and auditable. Buyers publish their evaluation criteria and weightings in the tender documents — giving every supplier the same advance knowledge of how marks will be distributed. This transparency is one of the defining features of public procurement under the Procurement Act 2023. It means that suppliers who read and respond to the evaluation criteria precisely — rather than writing what they assume the buyer wants — consistently score higher than those who do not.
Understanding how bids are scored in detail gives you the evaluator’s perspective that makes every bid writing decision strategic. The scoring framework the buyer publishes is not background context — it is the most important document in the tender pack, and reading it as a precise brief for every quality answer is the single most reliable way to improve your evaluation score.
The Three Dimensions of MAT Evaluation
Quality
Quality is typically the largest single component of a MAT score. In most public sector contracts, quality accounts for between fifty and seventy per cent of the total evaluation score. Some contracts weight quality even higher. The quality score reflects the strength of your written responses to the scored questions in the ITT — your methodology, your experience, your team, your approach to risk management and your delivery plan.
Quality evaluation uses structured scoring frameworks — typically a numerical scale from zero to five or zero to ten — with defined descriptors for each mark level. A maximum-quality score requires a response that fully addresses every element of the question, supports every claim with specific and relevant evidence, demonstrates a precise and credible delivery methodology, uses the buyer’s language throughout and connects the response directly to the buyer’s specific priorities and service environment. Anything short of this standard earns a lower mark level. Our guide to quality tender responses gives you the complete craft framework for achieving maximum quality scores consistently.
Price
Price accounts for the remaining percentage of the total MAT score — typically thirty to fifty per cent. The most common quality-price splits in public sector procurement are 60/40, 70/30 and 80/20 in favour of quality. This weighting is one of the most important strategic facts in the entire tendering landscape — because it means that price competition alone leaves the majority of available marks untouched.
In a 70/30 quality-price split, a supplier who scores ninety per cent on quality and prices at the market rate will consistently outscore a supplier who scores sixty per cent on quality and prices twenty per cent below the market rate. This arithmetic is straightforward — and it has profound implications for how suppliers should allocate their bid preparation investment. Investing in writing quality, evidence development and strategic tailoring produces higher returns than competing on price in the majority of MAT-evaluated contracts.
Price is scored through a comparative formula that awards full marks to the lowest-priced compliant submission and proportionally lower marks to higher-priced submissions. The specific formula varies by buyer — some use a simple linear calculation, others use a ratio or a capped model. Understanding which model the buyer applies allows you to model your pricing scenarios and assess the score impact of different pricing positions before finalising your commercial offer. Our guide to tender pricing strategy gives you the framework for making this calculation strategically rather than instinctively.
Social Value
Social value has become a formally weighted evaluation dimension across most public sector contracts since the government’s Social Value Model came into effect in 2021. Central government contracts apply a minimum ten per cent weighting to social value. Many local authorities, NHS trusts and housing associations apply significantly higher weightings — sometimes as much as twenty per cent of the total quality score.
Social value evaluation assesses the wider positive impact your organisation commits to delivering for communities, the environment and the economy as part of the contract. Strong social value responses are specific, locally relevant, measurable and connected to the buyer’s stated community priorities — not generic commitments that could apply to any contract in any location. Our guide to social value tender responses gives you the complete framework for developing and writing social value commitments that score at the top of the evaluation framework.
How MAT Evaluation Differs From Price-Only Procurement
Understanding what MAT evaluation replaced — and why — clarifies both the competitive opportunity it creates and the strategic approach it rewards.
Historically, many public sector contracts were awarded on price alone or with only minimal quality weighting. This approach produced a race to the bottom — with suppliers cutting service quality, squeezing margins and reducing workforce standards to compete on cost. The resulting contracts frequently underdelivered, required costly remediation and created poor outcomes for the service users they were designed to serve.
MAT evaluation was designed to address these failures. By weighting quality, social value and overall value alongside price, the framework creates an evaluation environment where suppliers who invest in delivery quality, workforce development and community impact are rewarded rather than penalised. It levels the playing field between large incumbents who compete on scale and price, and smaller, more agile organisations that bring genuine quality, specific local knowledge and authentic community relationships. For ambitious growing businesses, MAT evaluation is a fundamentally more favourable competitive environment than price-dominated procurement — if they understand how to compete in it effectively.
How to Win Under the Most Advantageous Tender Framework
Winning under MAT evaluation requires a strategic approach that is built specifically around how marks are distributed across the evaluation dimensions — not around how bids were won under older frameworks where price carried more weight.
Invest in Quality Above All Else
The single most impactful strategic decision available to any supplier tendering under MAT is to invest in quality writing quality above everything else. When quality accounts for sixty to seventy per cent of the total score, the quality of your written responses is the primary determinant of whether you win or lose. A well-resourced, strategically planned bid writing process — with proper storyboarding, win theme development, evidence integration and independent review — consistently produces higher quality scores than one assembled reactively under deadline pressure.
The resource you invest in quality writing is the resource that earns marks in the evaluation section that carries the most weight. Redirect any resource currently spent on price competition beyond a commercially viable level towards writing quality, evidence development and buyer research. The return on that redirection is measurable in every competitive evaluation your organisation enters.
Understand the Quality-Price Split Before Pricing
Always model the quality-price split before finalising your pricing position. If quality is weighted at seventy per cent and price at thirty, a ten per cent pricing premium costs you a fraction of the marks that a ten per cent quality improvement would earn. Price competitively — but price intelligently, with a clear understanding of the scoring arithmetic that governs the evaluation you are entering. Our guide to tender pricing strategy gives you the modelling framework to make this calculation precisely for every opportunity you pursue.
Build Your Social Value Response to the Buyer’s Priorities
Social value is not a supplementary section — it is a formal evaluation dimension that carries significant scoring weight in most MAT-evaluated contracts. Research the buyer’s social value priorities before writing begins. Connect every commitment to their specific community, their specific strategic agenda and their specific performance accountability. Make every commitment specific, measurable and deliverable within the contract term. Report against it through a defined monitoring framework. Social value evaluated to this standard consistently differentiates between suppliers whose overall scores are otherwise close.
Apply Your Win Themes Across Every Dimension
Your win themes should run through every dimension of the MAT evaluation — not just the quality answers. The same core competitive arguments that shape your methodology responses should be visible in your social value commitments, your pricing narrative and your executive summary. An evaluator who encounters the same compelling argument across multiple dimensions of the evaluation arrives at the scoring decision with a level of confidence in your organisation that a submission organised around disconnected individual answers cannot produce.
Use the Evaluation Criteria as Your Writing Brief
The evaluation criteria the buyer publishes are the most precise brief available for every quality answer in your submission. Read them before planning begins. Map every answer to the specific criteria it must address. Write to the highest mark descriptor — not to the second-highest. Review every completed answer against the criteria before submission, asking specifically whether it earns the maximum mark level and what it would need to contain to do so if it does not. Our guide to storyboarding your tender response shows you how to build this criteria-led approach into your planning process systematically.
MAT Evaluation Across Different Contract Types
The specific application of MAT evaluation varies across contract types, sectors and buyer organisations. Understanding the common variations helps you calibrate your approach for each opportunity.
Central government contracts typically apply the government’s Social Value Model with a minimum ten per cent social value weighting and quality-price splits commonly ranging from 60/40 to 70/30. The evaluation frameworks are formally structured and evaluators are trained in their consistent application.
Local authority contracts vary more significantly. Some local authorities apply higher social value weightings — reflecting the direct accountability they hold to their local communities. Others weight quality more heavily than price in service contracts where resident satisfaction and service continuity are the primary performance metrics. Always read the specific evaluation criteria in each ITT rather than assuming the weighting will mirror previous contracts with the same buyer.
NHS and healthcare contracts frequently weight quality at eighty per cent or higher — reflecting the critical nature of service quality in healthcare delivery and the primary accountability to patient outcomes. Price competition is correspondingly less determinative. Investment in writing quality and clinical evidence produces the highest return in these evaluations.
Housing association contracts typically balance quality and social value heavily, reflecting the dual accountability to residents and to the communities their estates serve. Local employment, resident engagement and sustainability commitments all carry meaningful scoring weight in these evaluations.
Framework agreements use MAT principles at both the appointment stage and in subsequent mini-competitions. Getting appointed to a framework and winning call-off contracts from it both require the same quality-focused approach — tailored to the specific criteria of each individual evaluation rather than relying on the framework appointment as implicit endorsement.
Frequently Asked Questions About the Most Advantageous Tender
What does MAT stand for in tendering?
MAT stands for Most Advantageous Tender. It is the evaluation standard introduced by the Procurement Act 2023, replacing the previous Most Economically Advantageous Tender (MEAT) framework. Under MAT, buyers assess the full range of value a supplier offers — quality, price, social value, innovation and sustainability — rather than selecting the lowest price alone.
What is the difference between MAT and MEAT?
Both frameworks require buyers to assess overall value rather than price alone. MAT goes further in explicitly broadening what counts as value — placing greater emphasis on social value, environmental impact, innovation and long-term public benefit. MEAT remains the correct terminology for contracts issued under the previous regulatory framework. MAT applies to contracts issued under the Procurement Act 2023, which came into force in February 2025.
How is the Most Advantageous Tender calculated?
Buyers assign percentage weightings to each evaluation dimension — typically quality, price and social value. Each submission receives a numerical score in each dimension. The scores are multiplied by the relevant weightings and summed to produce a total weighted score. The submission with the highest total weighted score wins the contract. The specific scoring formula and weightings are published in the tender documents.
What quality-price split is most common under MAT?
The most common quality-price splits in UK public sector procurement are 60/40, 70/30 and 80/20 in favour of quality. The specific split varies by contract type, buyer and sector. Healthcare contracts often weight quality at eighty per cent or higher. Social care and housing contracts frequently apply similar weightings. Always read the specific evaluation criteria in each ITT to confirm the weighting for that opportunity.
Does the lowest price always win under MAT?
No — and this is precisely the point of the MAT framework. The lowest price earns full marks on the price dimension but only thirty to forty per cent of the total score in most evaluations. A supplier who scores significantly higher on quality and social value can outperform a cheaper competitor even when pricing above the market rate. Competing on price alone under MAT leaves the majority of available marks untouched.
How does social value affect MAT scores?
Social value carries a minimum ten per cent weighting in central government contracts and often significantly more in local authority, NHS and housing association procurement. Strong social value responses — specific, locally relevant, measurable and connected to the buyer’s stated priorities — earn full marks in this dimension and can be the decisive differentiator between submissions whose quality and price scores are otherwise close.
