List of parliamentary constituencies in Somerset

The county of Somerset is currently divided into 7 parliamentary constituencies, which are all county constituencies.

2024 boundary changes
The 2023 Periodic Review of Westminster constituencies recommended changes to the contituencies of Somerset which came into effect at the 2024 general election. Due to changes to the legislation requiring stricter equality in the size of the electorates of constituencies, Somerset was longer treated as a distinct entity as previously, but was combined with Avon and Devon as a sub-region of the South West Region, resulting in significant change to the existing pattern of constituencies. In Somerset, only the constituency of Yeovil retained its name with relatively minor changes. The boundary changes created the cross-county boundary constituencies of Frome and East Somerset, Wells and the Mendips, and Tiverton and Minehead.

The boundary commission recommended the following seats within Somerset:

Containing electoral wards from Mendip


 * Frome and East Somerset (part)1
 * Glastonbury and Somerton (part)
