Following disappointing audience figures, the station was closed on 23 March 2007 and relaunched as 102.2 Smooth Radio the following Monday, following a successful format change request to Ofcom to play music oriented at listeners aged 50 and above.

102.2 Smooth FM was available on DAB across London, Central Scotland, the North East of England, South Wales and the Severn Estuary, Yorkshire and the West Midlands, as well as on Freeview channel 718.

The station also held exclusive live commentary rights for Chelsea FC soccer matches in London for the 2005/06 and 2006/07 seasons.

102.2 Smooth FM's presenters included: On 20 October 2006, GMG Radio announced that it was requesting a change of format for Smooth FM from Ofcom, moving the station away from its daytime soul and R&B remit, instead offering easy listening music and speech for the over 50s and an improved local news service.

Ofcom approved the changes on 8 December 2006, with the condition that GMG retained the 45 hours of jazz per week that constituted part of the former licence requirement.
