The BPE exhibitions are typically organised by a single photography club or by a number of clubs in the same geographic area that get together to organise a national exhibition. There is a self help group called the British Photographic Exhibition (BPE) which has 15 member exhibitions. The BPE was setup to encourage photographers to enter exhibitions and the members share ideas, promote each others exhibitions and generally work together to promote competitive photography.
The Photographic Alliance organises several competitions and exhibitions in the Uk. Entry is normally through an affiliated organisation (ours is The Midland Counties Photographic Federation).
