Public procurement is the process by which government departments, councils, health bodies and other public organisations buy goods, services and works using public money, under legal rules designed to secure value, fairness and transparency.
Procurement Act 2023
the Act
The Procurement Act 2023 is the legislation that replaced the previous EU-derived public procurement regulations in Great Britain, consolidating them into a single regime with greater emphasis on transparency, supplier access and outcomes rather than process.
It came into force on 24 February 2025. Among its changes: most economically advantageous tender (MEAT) became most advantageous tender (MAT), dynamic purchasing systems were replaced by dynamic markets, and a central digital platform now carries supplier registration and contract notices.
Government Commercial Agency
GCA
The Government Commercial Agency is the UK government's central commercial body, responsible for operating cross-government frameworks such as G-Cloud. It was formed on 1 April 2026 by merging Crown Commercial Service with the Cabinet Office's central commercial teams.
Existing frameworks, contracts and call-off agreements carried over unchanged at the transition. "Crown Commercial Service" is no longer the current name of the operating body.
G-Cloud 15
RM1557.15 · G-Cloud
G-Cloud 15 (RM1557.15) is the fifteenth iteration of the UK government framework through which eligible public bodies buy cloud hosting, cloud software and cloud support on pre-agreed terms, without running a full procurement each time.
It is operated by the Government Commercial Agency and is the first G-Cloud let under the Procurement Act 2023. Its lots are 1a and 1b (Cloud Hosting), 2a (Infrastructure Software as a Service), 2b (Software as a Service) and 3 (Cloud Support).
Public Procurement Gateway
PPG
The Public Procurement Gateway is the UK government service through which public sector buyers access framework catalogues and supplier listings. It replaced the Digital Marketplace, which has been retired.
Buyers register on the Gateway before using the Contract Award Service to run their call-off. "Digital Marketplace" should no longer be used as a current name.
Contract Award Service
CAS
The Contract Award Service is the government platform public sector buyers use to run a call-off against a framework agreement: searching supplier services, recording evaluation and completing the award.
Find a Tender is the UK public service where contracting authorities publish procurement notices, including planned, live and awarded contracts, making them searchable by suppliers.
A framework agreement is a pre-competed arrangement between one or more buyers and a set of approved suppliers, fixing terms and often pricing in advance so that individual purchases can be made quickly without a full procurement exercise.
A framework does not itself commit anyone to buy. Purchases are made through call-off contracts beneath it.
A call-off contract is the individual contract awarded under a framework agreement. It is the point at which a buyer actually commits to a purchase, on the framework’s pre-agreed terms.
Further competition
mini-competition
Further competition is a second, smaller competitive exercise run between suppliers already on a framework, used when a buyer wants to test price or approach against a specific requirement before awarding a call-off contract.
Some frameworks permit direct award without further competition where the requirement can be met by an existing catalogue entry. Buyers should follow their own procedures and keep the evaluation audit trail either way.
A dynamic market is an open supplier list under the Procurement Act 2023 that suppliers may join at any time, from which buyers run competitions. It replaced the dynamic purchasing system and, unlike its predecessor, can be used for all procurement types.
Most advantageous tender
MAT
Most advantageous tender (MAT) is the award test introduced by the Procurement Act 2023, under which a contract goes to the bid offering the best overall outcome against the published criteria, not necessarily the one scoring highest on price.
It replaced most economically advantageous tender (MEAT). The change removes the assumption that price must dominate, giving quality, social value and delivery outcomes more room in the assessment.
Social value is the wider economic, social and environmental benefit a contract creates beyond the goods or services bought (such as local employment, skills, carbon reduction or support for smaller suppliers) and is a scored element in most UK public tenders.
