It owns the National Pipe Organ Register and is the listing body for historic organs. BIOS is effectively the amenity society for the British organ.  It lobbies Government, Historic England and other national bodies on behalf of the instrument. BIOS is a registered charity No. 283936. 

A brief introduction to the organ, with information on some significant instruments plus sound files of the instruments in Tewkesbury Abbey and Liverpool Cathedral, can be found on the explorechurches website. CLICK HERE

  • Michael Sayers Founder of the National Pipe Organ RegisterBIOS members and users of the National Pipe Organ Register will be sad to learn of the unexpected death of Michael Sayers in Cambridge on Monday 4th October.

Our condolences go to his wife and family. A long-standing member of BIOS, he will be greatly missed.
