Restricted services have small coverage areas and are often used to broadcast at events, or within a particular establishment. They include hospital radio, drive-in movie soundtracks and commentary for outdoor events such as air shows. They also include radio services for religious observances such as Ramadan.

Restricted services mainly broadcast in the AM and FM broadcasting bands, but Ofcom doesn't always have sufficient frequencies available to meet demand. And interest in these services has been increasing during the Covid-19 pandemic, especially for drive-in events.

To better meet the demand, Ofcom has developed an innovative new method of spectrum planning that enables them to identify small gaps in spectrum use – between existing broadcast radio services in the FM band. Ofcom refers to these gaps as ‘limited coverage spectrum’. Because of the limited coverage that can be achieved using this spectrum, it is not suitable for national, local and community radio broadcasts, but is particularly suited for restricted service broadcasts.

Ofcom intends to make more efficient use of limited coverage spectrum to increase the overall spectrum resource available for restricted radio services. This should provide opportunities for more of these types of services to be licensed in future.

Ofcom also wants to simplify our licensing approach for restricted services and to make the application process more straightforward
