Celador's five radio stations in East Anglia are to become one as all programming is moved to Norwich.
Celador Radio has grown its station count by five with the purchase of The Beach, Dream 100, North Norfolk Radio, Radio Norwich and Town 102.
Anglian Radio is to share all peak programming between Dream and Town, and between North Norfolk, Radio Norwich and The Beach.
The move has been sparked because the landlord of Dream's current location has given them notice to be out by the end of June.
Radio Essex, Southend Radio and Chelmsford Radio breakfast presenter Dom Atkins has left the station to return to Dream 100 in Colchester.
Anglian Radio, which runs 5 local radio stations in the East of England, is ending its membership of the commercial radio body RadioCentre.
Tindle Radio's Town 102, Dream 100, Norwich 99.9, North Norfolk Radio and The Beach have all changed hands in a management buyout.
