Constituencies

2010 boundary changes
Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain Cumbria'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.

Proposed boundary changes 
See 2023 Periodic Review of Westminster constituencies for further details.

Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021. Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. The final proposals were published on 28 June 2023.

The commission has proposed that Cumbria be combined with Lancashire as a sub-region of the North West Region, with the existing seat of Morecambe and Lonsdale extending into southern Cumbria to create a cross-county boundary constituency. Copeland, Penrith and The Border, and Workington are abolished and replaced by the new constituencies of Penrith and Solway, and Whitehaven and Workington.

The following constituencies are proposed:

Containing electoral wards from Allerdale

 Penrith and Solway (part)
 Whitehaven and Workington (part)
