Shipbuilding, steel, artificial intelligence and energy infrastructure have been designated as critical to national security in new Cabinet Office guidance on public procurement. Departments are directed to prioritise British suppliers in these sectors where necessary to protect national security and reduce exposure to fragile global supply chains.
The measures include strengthened requirements on steel. For major government projects, departments must use British steel or publish a formal justification where overseas sourcing is proposed. Ministers say this step builds on the UK Steel Strategy and is intended to sustain domestic capacity across construction, defence and other strategic programmes.
A new Public Interest Test will change commissioning practice for services. Central government departments will be required to assess whether outsourced service contracts over £1 million could be delivered more effectively in-house. According to the government, this threshold captures more than 95 percent of central government contract value and is aimed at improving value for money while ending outsourcing by default.
Community impact is moved closer to the centre of award decisions. Bidders will be encouraged to embed local jobs, skills and apprenticeships in their tenders, and contracting authorities must publish and report annually on a specific social value goal for each contract above £5 million. The Cabinet Office states this reporting duty covers over 90 percent of central government contract value.
Commercial processes are also being modernised. A suite of AI-enabled tools and simplified contract terms will be introduced, with additional company data integrated into a central platform so small suppliers are not repeatedly asked for the same information across multiple bids. Officials say this will cut bid costs and administrative burden for SMEs.
Ministers frame the package as aligning economic resilience with national security objectives. The guidance sits alongside the government’s National Security Strategy and Modern Industrial Strategy, using the scale of public spending to reinforce critical supply chains and the skills pipeline in sectors judged strategically important.
Cabinet Office Minister Chris Ward said the reforms are intended to back British firms and the workforce behind them, arguing that government spending should support jobs and growth while protecting national security. He cited support for manufacturers and technology businesses from steelmaking to shipbuilding and smaller AI companies.
For contracting authorities, the changes will be most visible at early market engagement and specification stage. Security considerations will carry greater weight in award criteria for the four named sectors, and commercial teams will need clear audit trails where imported steel is selected. The in-house test introduces a mandatory gateway for higher-value service procurements before going to market.
For suppliers, competitive bids will benefit from demonstrable domestic content, workforce development and regional impact, particularly where facilities or jobs can be located near delivery sites. Firms in steel, shipbuilding, AI and energy infrastructure should review upcoming pipelines and ensure compliance documentation can evidence UK origin or set out robust national security justifications for imports.
Policy Wire analysis: The package signals a firmer use of national security justifications in procurement while retaining value-for-money tests. Buyers will need documented reasoning on market approach and sourcing, and suppliers should expect closer scrutiny of supply chains alongside more consistent social value reporting at the £5 million threshold. The promised central platform, if delivered as described, could reduce duplication for SMEs.
