Important changes to PMSE Spectrum usage (978 MHz for audio PMSE and drones)
From 11 March 2025 976.5 MHz to 979.5 MHz will not be available for outdoor audio PMSE use.
PMSE users can still apply for these frequencies for indoor use (with a maximum radiated power of 50mW). These frequencies will not be available to book on the PMSE web portal any licence applications for these frequencies must be sent to pmse@ofcom.org.uk
The reason for this change is that this band is shared with aeronautical safety equipment. More information is available here.
PMSE users can also now use 1015-1016 MHz; 1044-1045 MHz; 1075-1076 MHz and 1104-1105 MHz (both indoor and outdoor) – which was not available for use before. From 11 March 2025 these frequencies are available to book via the PMSE web portal
If you are using wireless microphones, talkback (walkie-talkies) and production services for radio and TV, you will need a programme-making and special events (PMSE) licence. They're required by law if directly associated with a performance or event.
May 2022 – Important Reminder
Please be aware that we aim to process licence applications within three working days but during busy periods (April to September) this may take longer. Please ensure you have considered this timescale when submitting applications.
It is a legal requirement that a Wireless Telegraphy Act licence is granted by Ofcom before you begin transmitting and that your equipment is operated in accordance with your licence. Penalties for unauthorised use vary but can include large fines and imprisonment so please ensure you submit your application with enough time to have the appropriate licence in place.
Most applications can also be made quickly and efficiently online without the need to wait. Please see our ‘Apply for a PMSE Licence’ page for more information or to use this service
