In the United Kingdom, the roll-out of digital radio has been proceeding since engineering test transmissions were started by the BBC in 1990 followed by a public launch in September 1995. The UK currently has one of the world's biggest digital radio networks, with about 500 transmitters, three national DAB ensembles, one regional DAB ensemble, 48 local DAB ensembles and an increasing number of small-scale DAB ensembles broadcasting over 250 commercial and 34 BBC radio stations across the UK. In London there are already more than 100 different digital stations available.[1] In addition to DAB and DAB+, radio stations are also broadcast on digital television platform as well as internet radio in the UK. Digital radio ensemble operators and stations need a broadcasting licence from the UK's media regulator Ofcom to broadcast.

In the long term there will be a switchover from analogue to digital radio when the AM and FM services will cease. The government has set criteria on the coverage and proportion of digital listening before this occurs. In 2018 the criteria of over 50% of digital radio listening was met which will now require the UK Government to review digital radio in view of a potential switchover.[2] In the same year, the BBC stated it would keep some FM radio for the foreseeable future.[3]

Digital radio in the United Kingdom is being promoted by radio stations and the broadcasting industry on the premise that it provides superior quality sound over AM, a wider choice of radio stations, is easier to use, and is resistant to the interference which other broadcast media are susceptible to.[4] On the other hand, critics say that coverage is not yet sufficient and the quality can be less than that of FM.

In the UK, 65.8% of all radio listening hours by the third quarter of 2021 were through digital platforms, with DAB making up the majority of digital radio listening (65.3% of digital radio listening).[5] In the first quarter of 2020, 66.7% of UK people aged 15+ claimed to have access to a DAB radio set at home.[6]
