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. 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 proposed that Suffolk be combined with Norfolk as a sub-region of the Eastern Region, with the creation of the cross-county boundary constituency of Waveney Valley. The seat of Waveney reverted to its former name of Lowestoft, and Bury St Edmunds was renamed Bury St Edmunds and Stowmarket.

The following constituencies were proposed:

Containing electoral wards from Babergh


 * South Suffolk

Containing electoral wards from East Suffolk


 * Central Suffolk and North Ipswich (part)
 * Lowestoft
 * Suffolk Coastal
 * Waveney Valley (parts also in Mid Suffolk and South Norfolk)

Containing electoral wards from Ipswich


 * Central Suffolk and North Ipswich (part)


 * Ipswich

Containing electoral wards from Mid Suffolk


 * Bury St Edmunds and Stowmarket (part)


 * Central Suffolk and North Ipswich (part)
 * Waveney Valley (parts also in East Suffolk and South Norfolk)

Containing electoral wards from West Suffolk


 * Bury St Edmunds and Stowmarket (part)
 * West Suffolk

2010
In the Fifth Review the Boundary Commission for England recommended that Suffolk retained its current constituencies, with changes only to reflect revisions to local authority ward boundaries and to reduce the electoral disparity between constituencies. The largest of these changes resulted in the effective transfer of one Borough of Ipswich ward from Central Suffolk and North Ipswich to the constituency of Ipswich.
