Changes to maritime spectrum - Ofcom consultation closes 3 June 2026

30 March 2026

Members will know that the maritime spectrum is the lifeline for marine communications and safety at sea. This week Ofcom opened a consultation on its plans to update UK maritime spectrum licences so that they align with modern international standards and ensure compatibility for vessels operating internationally.

The proposed changes are likely to impact both commercial marine and the wider coastal sector but have minimal impact on inland leisure boating

The current system has multiple overlapping licenses, including ship radios, port / shoreside stations, and small portable units. Ofcom proposes fewer and clearer categories, with greater emphasis on DSC (Digital Selective Calling), AIS (Automatic Identification System) and satellite-enabled comms. Older analogue-only radios may in time be phased out, or at least restricted. This could impact the superyacht and charter sectors as well, as sail training establishments, as they will need to become compliant with new equipment.

Planned changes aim to protect safety-critical frequencies, with safety-of-life channels (distress, GMDSS, coastguard) remaining a top priority. There is likely to be stricter rules for interference protection, with possible power limits and restricted areas near ports and coasts. Non-compliant radios may be prohibited.

Ofcom are also seeking input from stakeholders on the future of maritime radiocommunications and related technologies e.g., autonomous vessels, VDES (VHF Data Exchange System) - the next-generation upgrade to AIS which is designed to handle much more data and modern maritime communication needs.
