Question to the Department for Digital, Culture, Media & Sport:

To ask Her Majesty's Government what assessment they have made of the UK supply chain for submarine cable maintenance; and what steps they are taking to protect that supply chain.

The government takes the security and resilience of cables very seriously and we focus on the full range of threats and risks, including supply chain and repair arrangements. The Department for Business, Energy and Industrial Strategy is the lead department for the energy sector, including subsea energy cables. The Department for Digital, Culture, Media and Sport is the lead department for telecommunications policy, including the security and resilience of telecommunications subsea cables.

Subsea cables are privately owned and operated. Operators have arrangements in place to ensure a prompt response to damage or disruption. These arrangements draw upon national and international cable laying and repair companies. The departments work closely with the operators, regulators and others to assess risks and ensure that the appropriate mitigation measures, including the provision of specialist capabilities (such as installation and repair), are in place to enable an effective response to actual or potentially disruptive incidents. We keep these capabilities and the regulatory framework under review and engage with industry as part of this.

Information on cable repairs is not held but departments regularly engage with industry to keep informed.
