The county of Gloucestershire is divided into 7 parliamentary constituencies: 2 borough constituencies and 5 county constituencies, one of which crosses the county boundary with Wiltshire.
See 2023 Periodic Review of Westminster constituencies for further details.
For the 2023 Periodic Review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England opted to combine Gloucestershire with Wiltshire as a sub-region of the South West Region, with the creation of the cross-county boundary constituency of South Cotswolds, resulting in a major reconfiguration of the former The Cotswolds constituency, which was renamed North Cotswolds. These changes came into effect for the 2024 general election.
The following seats resulted from the boundary review:
Containing electoral wards from Cheltenham
Containing electoral wards in Cotswold
Containing electoral wards in Forest of Dean
Containing wards in Gloucester
Containing wards in Stroud
Containing wards in Tewkesbury
Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain Gloucestershire's constituencies for the 2010 election, making minor changes to realign constituency boundaries with the boundaries of current local government wards, and to reduce the electoral disparity between constituencies. Although the changes were minor, the Cotswold constituency was renamed The Cotswolds.
