## Boundary changes
### 2024

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 Suffolk with Norfolk as a sub-region of the East of England 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.
| Former name | Boundaries 2010–2024 | Current name | Boundaries 2024–present |
| Bury St Edmunds CC Central Suffolk and North Ipswich CC Ipswich BC South Suffolk CC Suffolk Coastal CC Waveney CC West Suffolk CC | | Bury St Edmunds and Stowmarket CC Central Suffolk and North Ipswich CC Ipswich BC Lowestoft CC South Suffolk CC Suffolk Coastal CC Waveney Valley CC West Suffolk CC | |

### 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.
| Name | Boundaries 1997–2010 | Boundaries 2010–2024 |
| Bury St Edmunds CC Central Suffolk and North Ipswich CC Ipswich BC South Suffolk CC Suffolk Coastal CC Waveney CC West Suffolk CC | | |
