Frequency allocation

From 1955 the band 88.0 - 94.6 MHz was used for three BBC national networks. Over the next 40 years, the band grew piecemeal to 87.5 - 108.0 MHz, allowing for five national networks and many local stations.

Until 1995, parts of the band had been used in the UK for mobile communications by police, fire brigades and the fuel and power industries. These parts were reallocated to broadcasting gradually over many years as the communications services were transferred to new equipment in other parts of the spectrum.

The current frequency plan is based on an ITU

Future switch off

The final report (written by Digital Radio Working Group) says FM should be switched off between 2017 and 2022.
And this switch off is recommended to boost digital radio & improve profit of UK digital radio IC suppliers. No further details about alternative use were provided
http://www.culture.gov.uk/images/publications/DRWG_Final_Report.pdf
It should be noted that this report is only a recommendation and successive Governments have admitted that FM VHF Band II analogue radio would not cease until the "majority" use "digital", so no actual date has ever been agreed. Digital listening figures however consistently include Satellite, DTT and online streaming, not just DAB. In any case there is a commitment to maintain community FM Radio. This means that as long as there are significant numbers of listeners on FM in the UK no Government is likely to take the politically unpopular decision to turn off analogue.
