Public sector procurement is a critical function that ensures essential services and infrastructure are delivered effectively across the UK. Whether you're working in central government, local authorities, or emergency services, purchasing goods and services requires strict adherence to regulations and a clear focus on community outcomes.
The system is currently undergoing significant changes, particularly with the introduction of the Procurement Act 2023, which aims to streamline procedures and improve supplier access. This guide explains how the system works, the core principles that govern it, and how you can approach it to secure the best value for taxpayers.
What is public sector procurement and why is it important?
Public sector procurement refers to the structured process through which public bodies purchase the goods, services, and works they need to operate and deliver public services. This includes everything from basic office supplies to high-value IT systems, professional services, and large infrastructure projects. Because these purchases are funded by public money raised through taxes, the process must be highly regulated to ensure fairness, transparency, and accountability.
It's important because it allows public organisations to maximise their output and deliver essential services efficiently. Beyond simply buying goods, public sector procurement is about securing value for money over the life of a contract. The Public Contracts Regulations 2015 (PCR15) have historically governed this space, instructing procurement processes to be fully transparent and fair. However, the new Procurement Act 2023, which came into full effect in February 2025, places a renewed emphasis on these values. It requires public buyers to consider broader social benefits, such as sustainability, innovation, and local economic growth, rather than just choosing the cheapest option available. By following these strict procedures, government entities ensure that public funds are spent wisely and that all suppliers are treated equally without discrimination.
What are the benefits of using a public sector procurement framework?
A procurement framework, also known as a framework agreement, is an umbrella agreement established between a public sector buyer and a pre-approved group of suppliers. These agreements set out the terms, including price and quality expectations, under which specific contracts can be awarded over a set period, which is usually up to four years.
Using a public sector procurement framework offers several distinct advantages for both buyers and suppliers.
- Reduced administrative burden: Because suppliers are already vetted during the framework's creation, buyers don't have to repeat the entire lengthy tendering process for every single purchase. This saves significant time and internal resources.
- Faster route to market: Frameworks allow contracting authorities to place orders quickly, which is crucial when project deadlines are tight or rapid mobilisation is required.
- Pre-qualified suppliers: Suppliers on a framework have already passed rigorous assessments regarding their financial stability, technical capability, and legal compliance. This gives buyers immediate confidence in the quality and reliability of the services provided.
- Built-in compliance: Frameworks are set up through fully compliant competitive processes, meaning any subsequent contracts automatically meet strict legal procurement regulations.
- Flexibility and scalability: Many frameworks are split into specific "lots" based on region or service specialism, allowing buyers to choose the most appropriate supplier for their exact needs.
How public sector procurement differs from private sector procurement
While purchasing goods and services is a universal business activity, public sector procurement and private sector procurement operate under completely different rules and motivations.
What are the key stages of the public sector procurement process?
The public sector procurement process is highly structured to ensure every decision is fair and justifiable. While exact steps can vary based on the contract's size, it generally follows these six stages:
- Planning and pre-market engagement: Before formal procurement begins, public bodies must define their needs and build a robust business case. Engaging with the market early helps buyers understand what solutions are currently available and how to best meet their objectives.
- Specification and market approach: The buyer develops a clear specification that focuses on the desired outcomes rather than just the input methods. They must then choose the best procurement route, such as an open procedure or a competitive flexible procedure, and publish the necessary tender notices to alert the market of the opportunity.
- Tendering and competition: The contracting authority issues an Invitation to Tender (ITT) and invites formal bids. During this phase, suppliers are evaluated on whether they meet mandatory eligibility criteria, such as financial standing and legal compliance.
- Supplier evaluation and contract award: Bids are evaluated against predefined criteria. Under the Procurement Act 2023, the focus has shifted to the "Most Advantageous Tender" (MAT), which means buyers consider social value, sustainability, and innovation alongside cost. Once a decision is made, an award notice is published, and a mandatory standstill period is observed to allow unsuccessful bidders time to request feedback.
- Contract signature and mobilisation: The contract is formally signed, and the project moves into the mobilisation phase. This includes handover activities and setting up governance arrangements to ensure the project starts smoothly and delivers value from day one.
- Contract management: Managing the contract after it's awarded is vital for achieving the intended outcomes. Buyers must monitor supplier performance against key performance indicators (KPIs) and maintain open communication to ensure continuous improvement and mitigate supply chain risks.
How a dedicated partner supports digital delivery in the public sector
Once you've completed the rigorous stages of a public sector procurement process, the immediate focus shifts to delivery. Even with a signed contract and a clear specification, public sector programmes frequently face severe in-house skills shortages that threaten strict deadlines.
