In a speech published by the Department for Science, Innovation and Technology on 29 May 2026, telecoms minister Liz Lloyd set out a more interventionist policy approach to subsea internet cables. Speaking at the Royal United Services Institute, she said the government will consult later this year on stronger criminal penalties for cable damage and consider wider security obligations for operators. (gov.uk) The speech treats subsea cables not as a narrow telecoms issue but as critical national infrastructure. Liz Lloyd argued that international payments, cross-border trade and the data flows needed for AI all depend on cables landing on UK shores, which explains why the policy package spans growth, deterrence and operational security.

According to the DSIT speech, the first strand is to expand system capacity rather than rely only on defensive measures. Many cables now landing in the UK were laid roughly two decades ago, and ministers say regulation is being reviewed so that replacement and expansion projects can proceed with fewer unnecessary barriers. (gov.uk) That includes a stated intention to remove avoidable environmental requirements for laying, maintaining and removing cables in deep waters where the speech says effects on marine life are limited. For operators and investors, the practical message is that Whitehall wants cable policy to support AI infrastructure, data-centre demand and wider digital trade rather than treat cable projects as a residual planning issue.

Ministers are also testing whether the UK should retain a domestic sovereign repair capability. The speech says a repair vessel can usually reach a cable fault in UK waters within eight days, and that market engagement is under way on keeping a UK-based, UK-flagged repair capability in place, with a decision due by the end of 2026. (gov.uk) Liz Lloyd linked that question to the National Wealth Fund's role in backing strategic infrastructure. As an example, she pointed to a £600 million deal for Eastern Green Link 4, presented as a model for using public finance to support supply chains, skilled jobs and infrastructure resilience at the same time.

On deterrence, the speech is more explicit. It rejects the idea that hostile activity around cables happens unseen and ties the policy shift to the Defence Secretary's disclosure that UK forces, working with allies, tracked Russian submarines operating in UK waters. The government line is that surveillance, attribution and visible military presence are already part of cable protection. (gov.uk) The sharper change is legal. The DSIT press release says ministers will consult on replacing legislation dating back around 140 years, with tougher fines and prison sentences for vessel owners and operators that intentionally or recklessly damage cables. That would move the regime away from a narrow sabotage model and closer to a modern critical infrastructure offence able to address conduct in the grey area between accident and hostile state action. (gov.uk)
Liz Lloyd also used the RUSI speech to argue that deterrence now depends on better visibility below the surface. The government wants cables and associated sensing systems to do more than transmit data, with operators and the state using new monitoring tools to identify seabed hazards and possible interference before service is interrupted. (gov.uk) For industry, this points to a shift from post-incident repair towards earlier detection, reporting and shared situational awareness. It also suggests that any forthcoming consultation is likely to focus not only on punishment after damage occurs, but on what operators, shipowners and public authorities are expected to do to prevent, detect and evidence incidents in the first place. This is an inference from the government's stated emphasis on sensing, incident response and clearer duties. (gov.uk)
The security strand is less dramatic but likely to affect operators more directly. In the speech, Liz Lloyd said most cable faults still arise from accidental causes such as seabed movement or anchors, and she formally endorsed the European Subsea Cables Association's new Fishing Liaison Guidelines as a practical means of reducing avoidable damage through better co-ordination between cable operators and the fishing sector. (gov.uk) The speech also says government is working with the National Protective Security Authority and the National Cyber Security Centre on updated physical and cyber guidance for cable landing stations. Building on the Telecommunications Security Act 2021, ministers intend to consult on baseline duties across the cable network, including risk management, response planning and rapid incident reporting; the accompanying DSIT press release adds that new emergency powers for government are also under consideration. (gov.uk)
A further strand concerns marine planning. The speech says analysis with The Crown Estate indicates the UK will need materially greater cable capacity by 2035, which means government is mapping and protecting future routes to avoid bottlenecks where multiple cables converge and to reduce conflict with other seabed uses, including offshore wind. (gov.uk) The international piece is also moving into operational territory. Liz Lloyd said the UK and Ireland will run a joint exercise later in 2026 to test response arrangements for a major cable disruption, and she linked that work to wider co-operation through the International Advisory Body for Submarine Cable Resilience. Taken together, the programme outlined at RUSI amounts to a more structured UK policy for subsea cables: lighter-touch permitting where possible, stronger criminal sanctions, firmer operator duties and more formal cross-border contingency planning.
