2010 boundary review

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.

Name	Boundaries 1997-2010	Boundaries 2010–present
1. Bracknell CC
2. Maidenhead CC
3. Newbury CC
4. Reading East BC
5. Reading West CC
6. Slough BC
7. Windsor CC
8. Wokingham CC

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 and published their initial proposals on 8 June 2021. ^[4]

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 Egham in the Surrey borough of Runnymede. The two Reading constituencies (East and West) would be abolished and revert to a single constituency, with two new constituencies created, named Earley and Woodley, and Mid Berkshire. ^{[5] [6]}

The following constituencies are proposed:

Containing electoral wards from Bracknell Forest

• Bracknell CC
• Maidenhead CC (part)

Containing electoral wards from Reading

• Earley and Woodley BC (part)
• Mid Berkshire CC (part)
• Reading BC

Containing electoral wards from Slough

• Slough BC
• Windsor CC (part)¹

Containing electoral wards from West Berkshire

• Mid Berkshire CC (part)
• Newbury CC

Containing electoral wards from Windsor and Maidenhead

• Maidenhead CC (part)
• Windsor CC (part)¹

Containing electoral wards from Wokingham

• Earley and Woodley BC (part)
• Wokingham CC

¹also includes part in the Surrey borough of Runnymede

Revised proposals will be published in late 2022 and the final report will be submitted in June 2023.
