Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England^[3] decided to retain Berkshire's 8 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, including the transfer of Bray from Windsor to Maidenhead, Binfield from Bracknell to Windsor and the return of Foxborough ward from Windsor to Slough.

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.^[4] 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 Berkshire be combined with Hampshire and Surrey as a sub-region of the South East Region. As a result, Windsor now includes Englefield Green in the Surrey borough of Runnymede. The two Reading constituencies (East and West) would be abolished and revert to a single constituency (Reading Central), with two new constituencies created, named Earley and Woodley, and Reading West and Mid Berkshire.^[5][6]

The following constituencies are proposed:

Containing electoral wards from Bracknell Forest

• Bracknell
• Maidenhead (part)

Containing electoral wards from Reading

• Earley and Woodley (part)
• Reading West and Mid Berkshire (part)
• Reading Central

Containing electoral wards from Slough

• Slough
• Windsor (part)¹

Containing electoral wards from West Berkshire

• Reading West and Mid Berkshire (part)
• Newbury

Containing electoral wards from Windsor and Maidenhead

• Maidenhead (part)
• Windsor (part)¹

Containing electoral wards from Wokingham

• Earley and Woodley (part)
• Wokingham

¹also includes part in the Surrey borough of Runnymede
