Public procurement is how public bodies buy from suppliers.
It is the structured process a public organisation uses to define a need, choose a buying route, consider suppliers, make an award and manage the resulting contract.

- 1Public need
A public body identifies an outcome, service, product or work it needs.
- 2Buying process
It chooses a lawful route, publishes the required information and assesses suppliers.
- 3Supplier response
Suppliers decide whether to take part and submit the information the process asks for.
- 4Award and contract
The buyer records its decision and, where the process continues, enters into a contract.
Why the process exists
The buyer is spending public money.
Public buyers work within rules and internal controls intended to support transparency, fair treatment, accountable decisions and value for money. The exact route depends on the buyer, the contract, its value and the legislation that applies.
For a supplier, that means a public sale is rarely a single conversation. The published record may begin before a competition, continue through a tender and show what happened after the award.
Who buys
Public procurement reaches every supplier industry.
The buyer may be national or local, and the requirement may be a product, service or work.
- Central and local government
- Departments, agencies, councils and other public authorities buy everything from professional advice to highways work.
- Health and education
- NHS bodies, universities, colleges and schools procure clinical services, estates work, supplies, technology and support.
- Housing, emergency services and utilities
- Social housing organisations, police, fire services and some utility bodies also publish procurement activity.
Six different ideas
Do not use every procurement word to mean “a tender”.
A single procurement can produce several notices and decisions. Keeping the objects separate helps you act on the right signal.
- Procurement
- The whole buying process, from identifying the need through award, contract and delivery.
- Opportunity
- A practical chance for a supplier to prepare, engage or compete. It is not a formal notice type by itself.
- Notice
- A published record about part of the process. Different notices can signal planning, competition, award or contract activity.
- Tender
- Formally, the supplier's bid. In everyday use, people also use the word for the competition around it.
- Award
- The buyer's decision about which supplier or suppliers should receive the contract.
- Contract
- The binding agreement under which the chosen supplier provides the goods, services or works.
UK scope
There is not one procurement rulebook for every UK buyer.
The Procurement Act 2023 regime applies to relevant procurements begun on or after 24 February 2025 by contracting authorities in England, Wales and Northern Ireland, and to reserved procurement in Scotland. Transitional and specialist cases can follow earlier or different rules.
Devolved Scottish authorities generally remain under Scottish procurement legislation and use Public Contracts Scotland. Always check the official notice and documents for the route that governs the procurement in front of you.
