The present diocese covers the overwhelmingly greater part of the (ceremonial) county of Somerset and a small area of Dorset.

The Episcopal seat is located in the Cathedral Church of Saint Andrew in the city of Wells in Somerset.

In late 2013 the Church Commissioners announced that they were purchasing the Old Rectory, a Grade II-listed building in Croscombe for the Bishop's residence.

In 1197 Bishop Savaric FitzGeldewin officially moved his seat to Glastonbury Abbey with the approval of Pope Celestine III.

[34][35] Ralph of Shrewsbury, Bishop of Bath and Wells, appears as a character in the 1994 fantasy novel The Dragon, The Earl and The Troll, by Gordon Dickson.
