Pirate radio stations are unlicenced; they often use radio frequencies that are not being used. However, if those frequencies are close to the radio service you want to listen to, it can interfere with reception.
Interference from Pirate Radio.
Pirate radio stations are illegal, often using low-power transmitters and normally serve very specific locations. Even at low power, a pirate radio station transmitting close to where you live can block out reception of licensed radio stations.
Reporting a Pirate Radio station.
The RTIS does not deal directly with interference from pirate radio stations. Instead, you will need to report instances of pirate radio stations directly to Ofcom. They have the regulatory powers to deal directly with interference from pirate radio broadcasts.
What information is useful to Ofcom?
It will be helpful to Ofcom if you are able to provide some basic information, including your postcode, the station that's being interfered with, dates and times when it happens and how long it lasts. If you can identify the pirate station that you think is causing the problem, tell them its frequency. It would also be useful to provide any phone numbers broadcast and names of DJs, as well as a description of the type of music played.
Broadcasters who have problems with pirate radio should complete the broadcaster only pirate radio web form.
If you don't have web access, please ring Ofcom's switchboard on 0300 123 3333 during weekday office hours, or write to them at:
