List of parliamentary constituencies in Hertfordshire

Context of the 2019 result. The county elected 10 Tory MPs and 1 Lib. Dem. MP. Luton, Bedfordshire returned two Labour candidates, it forms a small projection into the county's shape.

Limits of the seats were amended by the Fifth Periodic Review of Westminster constituencies carried out by the Boundary Commission for England for future elections which have included 2010, 2015, 2017 and 2019. Each constituency is made up of whole or partial local government wards, which elect councillors at English local elections. Nine are designated as county constituencies (in which candidates can spend more per head than their borough counterparts). Two are borough constituencies.

The Boundary Commission for England decided not to change Hertfordshire's representation in Parliament for the 2010 election. It did however suggest slight boundary changes to reduce electoral disparity. The recommendations, which became law with the Parliamentary Constituencies (England) Order 2007, also ensured that local government wards in Hertfordshire would no longer be split between two Parliamentary constituencies.^[5][6]

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.^[7] 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 Hertfordshire be combined with Bedfordshire as a sub-region of the Eastern Region, with the creation of the cross-county boundary constituency of Hitchin. As a result of the changes, Hitchin and Harpenden would be abolished and replaced by a new constituency named Harpenden and Berkhamsted.^[8][9][10]
