Independent National Radio (INR) is the official term for the three national commercial radio stations currently or previously broadcasting on analogue radio in the United Kingdom. The two stations currently or previously broadcasting on AM were allocated frequencies previously used by BBC Radio 3 (to be used by INR2) and BBC Radio 1 (to be used by INR3).
The stations came about following the Broadcasting Act 1990 which allowed for the launch of independent national radio (INR) stations in the United Kingdom.[1] The Radio Authority was mandated to award three INR licences. The FM licence (INR1) had to be for a 'non-pop' station and one (INR3) had to be for a predominantly speech-based service. The remaining licence (INR2) was to be open to 'all-comers'. The licences were to be awarded to the highest cash bidder, providing that the applicant met criteria set down in the Broadcasting Act.[2]
Plans for a fourth station, using 225 kHz long wave, were mooted in 1996 but were abandoned by the Radio Authority after consultation with the radio industry which found that there was no interest in launching a station on that frequency due to the costs involved, especially to cover all of the country given that the frequency would only provide partial-UK coverage. The frequency had originally been allocated to the BBC but it had never been used.
INR licences come with certain privileges and responsibilities that are not shared by Independent Local Radio stations:[3]
As of 2011, the INR licence holders paid Ofcom a nominal annual fee of £10,000.[4]
All three stations are also available nationally on DAB, digital TV and online.
