1832–1868: The Hundreds or Liberties of Bath Forum, Bempstone, Brent and Wrington, Bruton, Catsash, Chew and Chewton, Norton Ferris, Frome, Glaston Twelve Hides, Hampton and Claverton, Horethorne, Keynsham, Kilmersdon, Mells and Leigh, Portbury, Wellow, Wells Forum, Whitstone, Winterstoke, and Witham Friary, and the parts of the Hundred of Hartcliffe with Bedminster excluded from the limits of the City of Bristol.

It surrounded the cities of Bath and Wells (although both were boroughs electing MPs in their own right, freeholders within these boroughs who met the property-owning qualifications for the county franchise could vote in East Somerset as well, as could those in Frome); other towns in the division were Glastonbury, Burnham-on-Sea, Clevedon, Keynsham, Midsomer Norton, Portishead, Radstock, Shepton Mallet, Somerton and Weston-super-Mare.

The Second Reform Act brought about significant boundary changes, which came into effect at the 1868 general election, as Somerset was given a third county constituency.

The revised East Somerset constituency was now defined as consisting of the Long Ashton, Axbridge, Keynsham, Temple Cloud and Weston Petty Sessional Divisions.

This was a predominantly rural constituency, though with some industry in the towns (notably brewing and bootmaking), and a strong Nonconformist religious tradition.
