How to Embed the Procurement Act 2023 Directly into Your Category Management Process

Category Management, MAT, Competitive Flexible Procedure

A practical, no-fluff guide for Category Managers, Heads of Procurement, and Transformation Leads Nine months after go-live (24 February 2025), one thing is clear:

the Procurement Act 2023 has turned category management from a back-office function into one of the most powerful levers of domestic policy available to the British state. The tools, templates and precedents now exist to do this quickly, defensibly and at scale. 

Stop treating the Act as a compliance burden. Start treating it as the single biggest upgrade your category management process has ever received.

1. What Actually Changed – The Quick Recap

Here are the four biggest shifts that turned MEAT into MAT overnight:  

Old MEAT World (pre-24 Feb 2025)  New MAT World (post-24 Feb 2025)  Category Manager Super-power Unlocked 
Price 60–80 %, Quality 20–40 %  Price rarely >60 % (central policy guidance, not statutory cap)  Legally run 50/50 or even 30/70 price/quality splits 
Social value = mandatory 10 % bolt-on  Social value routinely 20–35 % and fully integrated into core award  Net-zero, skills, local SMEs and resilience become genuine differentiators 
Evaluation criteria fixed 12 months ahead  Dynamic, refinable criteria under Competitive Flexible Procedure  Co-design solutions and KPIs with the market mid-competition 
One-shot tender (Open or Restricted)  Multi-stage, iterative dialogue now the norm  Run 3–6 stage processes that feel like “BAFO × 3” – fully compliant 

 2. How the Procurement Act 2023 Rewires the 7 Classic Category Management Steps

This is the exact roadmap the most advanced teams are now using to go from old-school   

Step  Traditional (MEAT-era) Practice  Act-Integrated Reality (2026)  Mandatory under the Procurement Act 2023  Strongly Recommended / Best Practice (2025–26 reality) 
1  Basic ABC/XYZ segmentation  Full Act lenses applied from day one  None directly in spend analysis  Carbon baseline (Scope 1–3), modern slavery risk map, SME % & 30-day payment data published on Central Digital Platform; NPPS priority mapping 
2  Porter’s Five Forces only  Supplier power rebalancing + prompt-payment analysis  If preliminary market engagement is carried out → publish PME notice before tender notice (s.16)  Publish PME Report ≥30 days before PIN; explicit supplier-power and payment-performance analysis 
3  30-page strategy, annual refresh  8–12 page “Value Levers” strategy, locked for 4 years  None – no statutory requirement for 4-year strategies  Explicit MAT weighting ranges for next 4 years; Board/Cabinet/s151 officer sign-off 
4  Fixed 12-month pipeline  Rolling 18-month pipeline published on Find a Tender + Contracts Finder  Publish Pipeline Notice covering at least the next 18 months (s.93 – mandatory for contracting authorities above threshold)  Lotting/direct award/reserved contract justification published in the notice 
5  MEAT 60–80 % price  Full MAT design workshop → published attribute tree  Publish award criteria and weightings before tenders invited (s.23); refinement criteria published at each stage (s.24)  Price rarely >60 % (central policy); social value/net-zero/resilience typically 20–40 % integrated 
6  One-shot ITT or Restricted procedure  Competitive Flexible Procedure (3–6 stages) in most >£12 m tenders  If refinement occurs → publish/record changes between stages for transparency (s.24)  Run 3–6 stage CFP with recorded refinement of criteria/solutions; early market engagement report published 
7  Standard KPIs + LADs  Outcome-based payment mechanisms + 30-day payment flowed down  Contract Details Notice + redacted contract within 30 days (s.53)
KPI list + performance data within 120 days for contracts >£5 m (s.71)
30-day payment terms flowed down and reported quarterly (s.69) 
Quarterly payment monitoring dashboard; outcome-based KPIs tied to social/environmental value 

 3. The Category Manager’s New Risk Register (and How to Sleep at Night)

The Act increased certain risks, but it also handed you the mitigations on a plate. Here’s what keeps category managers awake – and how they fix it.  

Risk  Pre-Act Likelihood  Post-Act Likelihood  Everyday Mitigation Now Used 
Judicial review for “non-transparent” criteria  Low  High  Publish full attribute tree + weighting rationale at PIN stage 
Suppliers gaming social value  Medium  Very High  Require audited Social Value Delivery Plans + 10–15 % retention on related KPIs 
Category team burnout  Medium  Very High  Recruit hybrid “Commercial Policy Partner” roles (lawyer + category manager skill-set) 
Political flip-flopping on priorities  Low  Medium  Lock MAT weightings into 4-year strategies approved by Board/Cabinet 

 4. Tools Every Category Manager Needs in 2026

These are the plug-and-play tools that turn theory into reality, all live and compliant right now:  

  • MAT Attribute Library – pre-approved, scored attributes with case-law references  
  • Carbon & Social Value Calculators embedded in Atamis and Jaggaer (both released fully compliant versions Q3 2025) 
  • Dynamic Pricing Mechanism clause pack – switch from fixed to index-linked mid-contract on trigger events (already in ~20 % of new frameworks) 
  • Skills & Apprenticeship Tracker auto-integrated into contract management modules (Jaggaer, Delta, SAP Ariba) 

 5. The Next Frontier – Category Strategies as Instruments of Statecraft

The most advanced teams have reviewed category strategies and updated the “Value Levers” which transforms their documents to read like mini-industrial strategies:  

  • Target MAT weightings locked for the next four years  
  • Desired future supplier market shape (e.g., “at least three credible UK manufacturers by 2029”)  
  • Deliberate intervention points (pre-market engagement, lotting, payment mechanisms)  
  • Permanent Secretary / Council Cabinet level sign-off 

 In recent spending-review discussions (e.g., SR25 consultations), advanced teams have piloted ‘Value Levers’ documents, with early examples informing HMT efficiency advice—potentially treated as fiscal levers in future events. 

6. Are You Ready? Self-Assessment Matrix (2026)

One traffic-light row per step. Be honest – most teams are still amber or red on at least three of these. Where are you?  

Step  Red (High risk / Non-compliant)  Amber (Work in progress)  Green (Fully compliant & defensible) 
1  No carbon baseline, no modern slavery map, no SME/payment data  Data exists but not published or refreshed annually  Full Act lenses applied + data published on Central Digital Platform 
2  No recorded pre-market engagement  Some soundings taken but not published  Published Pre-Market Engagement Report ≥30 days before PIN + supplier-power analysis 
3  Still using old MEAT templates; price >60 % not justified  Draft 4-year strategy exists but not Board-approved  8–12 page Value Levers strategy with locked 4-year MAT ranges, Cabinet/s151 sign-off 
4  Pipeline not published or only 12 months  18-month pipeline published but no lotting justification  Rolling 18-month pipeline + published lotting/direct award justification 
5  Price >60 % or social value still a 10 % bolt-on  Price ≤60 % but no published attribute tree  Full published MAT attribute tree; social value/net-zero/resilience 20–40 % integrated 
6  Still using one-shot Open/Restricted for complex buys  Using CFP but <3 stages and no recorded refinement  3–6 stage CFP with published refinement of criteria/solutions between stages 
7  Notices late/redacted; no KPI performance data  Notices published but performance data missing  Contract Details Notice (30 days) + full KPI performance data (120 days) + quarterly payment monitoring 

 Final Thought 

The Procurement Act 2023 did not just change the rules of tendering. It handed category managers the steering wheel of £385 billion of annual public spend. Nine months in, the wheel is being turned – sometimes boldly, sometimes nervously – but it is being turned. The quiet revolution is no longer quiet.

It is the sound of thousands of category managers rewriting strategies, defending ambitious MAT criteria in pre-action correspondence, and discovering that when you are finally allowed to buy the most advantageous tender, you can actually start to fix some of the country’s biggest problems.  

The question for 2026 is no longer “Will MAT work?”. It is “How far are we prepared to push it?”. 

Start with one category in Q1: 

  • The tools are ready. 
  • The Act is on your side. 
  • Go turn the wheel.
