For the 2023 Periodic Review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England opted to combine Berkshire with Hampshire and Surrey as a sub-region of the South East Region. As a result, Windsor now includes Englefield Green and Virginia Water 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.

The following constituencies were 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 of the Surrey borough of Runnymede
