Public procurement UK: a supplier's guide to the Procurement Act 2023

Public procurement in the UK is the process by which government departments, councils, the NHS and other public bodies buy goods, services and works. The Procurement Act 2023 came into force on 24 February 2025 and replaced most of the previous regulations in England, Wales and Northern Ireland. This guide explains the main changes for suppliers and how a growing business can compete.

What changed under the Procurement Act 2023

  • A single set of rules replacing several older regulations
  • A central digital platform where suppliers register once
  • A new flexible competitive procedure alongside open tenders
  • A duty on buyers to consider barriers facing small and medium-sized businesses
  • Greater transparency, including notices across the contract lifecycle
  • A central debarment list for suppliers excluded for serious failings

How to find public sector opportunities

Opportunities are published on the Find a Tender service and, for lower values, Contracts Finder. Many buyers also use frameworks, so being on the right framework can matter as much as winning a single tender.

How to bid well

Public tenders are scored against published criteria. Write to the scoring guide, not to your brochure. Price is usually weighted, but quality, social value and delivery risk often carry more marks than suppliers expect. Evidence beats claims: named examples, measurable outcomes and a credible mobilisation plan.

Public procurement for buyers

Public bodies face the same cost pressures as private firms, with extra process. Good category planning, spend analysis and category management help buyers use the new flexible procedure well.
