UK Government Prioritises British Suppliers in National Security Sectors
The UK government has introduced new guidance that will prioritise British suppliers for public contracts in sectors deemed vital to national security. These sectors include shipbuilding, steel production, artificial intelligence (AI), and energy infrastructure. Under the new rules, government departments must either use British steel or provide a justification for sourcing it from overseas.
Accelerated Policy Amid Global Supply Chain Concerns
This policy, which was already in development, has been brought forward due to the ongoing war in the Middle East and the resulting shocks that have highlighted the fragility of global supply chains. The conflict has underscored the risks associated with over-reliance on international suppliers for critical materials and technologies.
Chris Ward, a Cabinet Office minister, stated: “These reforms are about using the full weight of government spending to support British jobs, protect our national security and grow our economy.” He emphasised that the new approach would benefit workers across the country, from steelworkers in Port Talbot to tech startups in Cambridge and Brighton.
Public Interest Test and Insourcing Strategies
In addition to prioritising British suppliers, the government has implemented a Public Interest Test. This test requires departments to assess whether outsourced service contracts valued over £1 million could be delivered more effectively in-house. The test is expected to cover more than 95% of central government contracts by value.
Larger departments with annual spending exceeding £100 million will also be required to publish an “insourcing” strategy. This strategy must outline plans to bring services back in-house where they represent better value for money. Ward added: “Through our new Public Interest Test, we’re also calling time on the era of ‘outsourcing by default’, and bringing public services back in house, where they belong.”
Focus on Community Impact and AI Tools
The new policies place a strong emphasis on community impact. When outside contractors are involved, firms will be encouraged to demonstrate how their bids contribute to national and regional schemes, including the creation of local jobs and apprenticeships. This move aims to ensure that procurement decisions benefit local economies and communities.
As part of the new policy, the government has developed a suite of AI tools designed to streamline the commercial process. Ward explained: “We’re also stripping away the red tape that has held back our small businesses and charities for too long, using new AI tools to make bidding for work simpler, faster, and fairer.”
Alignment with National Security Strategy
These measures follow the publication of the National Security Strategy in June, which sought to align national security with economic growth and enhance the resilience of British supply chains. The government is utilising national security exemptions under international trade agreements, such as the World Trade Organisation’s Agreement on Government Procurement (GPA), to implement these rules.
Clear guidance will be provided to departments to protect the UK’s economic security and build resilience in the four key sectors. Other related measures, including policies specifically tied to national security and shipbuilding, are currently being developed.
The government’s comprehensive approach aims to strengthen domestic industries, reduce dependency on foreign suppliers, and ensure that public spending supports British jobs and economic stability in an increasingly uncertain global landscape.
