The Office of Communications (Ofcom) has varied UK radio transmitter licenses to protect the general public from harmful radio emissions. As a result, all UK ship station license holders must be able to show evidence of their compliance with the protection criteria.

Ofcom has published two guidance documents:

The targeted guidance indicates that Ofcom requires compliance evidence for specific Global Maritime Distress and Safety System (GMDSS) radio communications installations and for radar installations. The guidance also identifies many product types for which no evidence is needed.

This marine information note (MIN) contains additional general and safety related information for vessels (ship station licence holders).

Please note the Maritime and Coastguard Agency (MCA) has contributed to Ofcom consultations on this matter but is not responsible for enforcement, the MCA is therefore not able to offer advice on compliance with the protection criteria.
