Public sector procurement plays a central role in shaping industrial capacity, employment, and economic resilience across the United Kingdom. Recent supply chain disruptions have highlighted the need for stronger domestic capability in sectors linked to national security and infrastructure.
The UK government confirmed new procurement rules on 26 March 2026 requiring departments to prioritise British suppliers in shipbuilding, steel, AI, and energy infrastructure contracts.
Announced by the Cabinet Office, the guidance introduces measures including domestic sourcing expectations, a Public Interest Test for contracts over £1 million, and reporting requirements. The changes aim to strengthen supply chains, support jobs, and align public spending with national security and economic resilience objectives.
Government sets new procurement priorities for national security
The Cabinet Office confirmed that procurement guidance will prioritise sectors linked to national security, including shipbuilding, steel, AI, and energy infrastructure. The announcement states that departments should consider domestic capability when awarding contracts.
According to the Cabinet Office, this approach reflects recent supply chain disruptions and the need to strengthen resilience. By directing spending towards domestic providers, the policy aims to support continuity across essential sectors.
Four sectors identified as critical to resilience
The government identified shipbuilding, steel, AI, and energy infrastructure as sectors requiring focused support through procurement decisions. The Cabinet Office stated that these industries are essential to national security and economic stability.
Meanwhile, prioritising these sectors is intended to ensure that domestic capacity can meet demand during periods of disruption. The designation supports long-term planning across industry and government.
- Shipbuilding
- Steel production
- Artificial intelligence systems
- Energy infrastructure
New rules to favour British suppliers and steel use
The Cabinet Office outlined new expectations requiring departments to prioritise British suppliers where national security considerations apply. For steel procurement, departments must either use UK-produced steel or provide justification for sourcing from overseas.
This requirement aligns with the UK Steel Strategy and is intended to increase demand for domestic production. By introducing justification requirements, the policy aims to influence procurement decisions toward UK industry.
Procurement Requirements Overview
| Domestic sourcing | Departments encouraged to prioritise UK suppliers for security-related contracts |
| Steel requirement | Use of British steel or formal justification for overseas sourcing |
| Policy alignment | Supports UK Steel Strategy and national security objectives |
Public Interest Test to assess outsourcing decisions
The Cabinet Office introduced a Public Interest Test requiring departments to assess whether contracts over £1 million could be delivered in-house. The guidance states that this applies to over 95% of central government contracts by value.
Additionally, the test is designed to evaluate cost-effectiveness and service delivery outcomes. By requiring formal assessment, the policy aims to reduce default outsourcing practices.
- Applies to contracts over £1 million
- Covers majority of government contract value
- Requires in-house delivery assessment
- Aims to improve value for money
Contract Oversight and Reporting
| Public Interest Test | Applies to contracts above £1 million threshold |
| Reporting requirement | Annual publication for contracts above £5 million |
| Coverage | Over 90% of contracts by value subject to reporting |
Social value and local economic impact requirements
The Cabinet Office stated that companies bidding for contracts will be encouraged to demonstrate how they create local jobs, skills, and apprenticeships. This approach places community impact alongside cost and delivery considerations.
Meanwhile, departments will publish and report annually on social value goals for contracts over £5 million. The measure is intended to increase transparency in how public spending supports communities.
Ministerial Comments
Chris Ward, Cabinet Office Minister said;
“This Government is backing British businesses and the working people who power them. These reforms are about using the full weight of Government spending to support British jobs, protect our national security and grow our economy.”
“Whether you make steel in Scunthorpe, build ships on the Clyde or run a small tech firm in the Midlands, this Government is on your side.”
In Conclusion
The updated procurement guidance introduces new expectations for how government contracts are awarded across sectors linked to national security. By prioritising domestic suppliers, introducing oversight tests, and requiring social value reporting, the policy aims to strengthen supply chains and support UK industry.
The approach reflects a broader alignment between public spending, economic resilience, and workforce development.
