Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain the existing 8 constituencies in East Sussex, with minor changes to realign constituency boundaries with those of current local government wards, and to reduce the electoral disparity between constituencies.

Name	Boundaries 1997-2010	Boundaries 2010–present
Bexhill and Battle CC Brighton, Kemptown BC Brighton, Pavilion BC Eastbourne BC Hastings and Rye CC Hove BC Lewes CC Wealden CC

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.^[5] 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 East Sussex be combined with West Sussex as a sub-region of the South East Region, resulting in the creation of a new cross-county boundary constituency named East Grinstead and Uckfield. The resultant changes to existing constituencies would entail the abolition of Wealden and the creation of the new constituency of Sussex Weald. Brighton Kemptown will be renamed Brighton Kemptown and Peacehaven, and, although its boundaries are unchanged, it is proposed that Hove be renamed Hove and Portslade.^[6][7][8]

The following constituencies are proposed:

Containing electoral wards from Brighton and Hove

• Brighton Kemptown (part)
• Brighton Pavilion
• Hove and Portslade

Containing electoral wards from Eastbourne
