Britain will increase investment screening in the semiconductor and water industries
The government of United Kingdom on Thursday said it will refine its national security investment screening rules, including tightening oversight of sectors such as water infrastructure and advanced semiconductors. The move is aimed at ensuring that the country’s investment screening regime keeps pace with evolving national security risks.
Britain already has laws that require certain private investments to be referred to the government for closer scrutiny if they involve sensitive sectors. Officials said the reforms are intended to update the system so it can better protect strategic industries and critical infrastructure from potential security threats.
Under the proposed changes, “off-the-shelf” systems powered by artificial intelligence will no longer automatically fall under mandatory screening requirements. Instead, the government plans to focus more closely on companies that develop or significantly modify advanced AI technologies, which are considered more strategically sensitive.
The government also announced that water companies will be classified as a sensitive sector for the first time. This means investments in major water operators and large independent providers will require mandatory national security screening. However, the rules will not apply to companies that are only part of the broader supply chain for water services.
In addition, the government plans to create separate standalone categories for semiconductors and critical minerals. These areas are increasingly viewed as vital to national security because they underpin modern technologies ranging from electronics to defence systems and energy infrastructure.
Officials said the government is also considering whether the list of critical minerals should be expanded in the future, reflecting growing global competition for resources used in advanced manufacturing and technology.
The existing investment screening rules will remain in force for now. The updated framework will take effect only after new secondary legislation is introduced later this year.
