Further to the completion of the 2023 Periodic Review of Westminster constituencies, Waveney was abolished and Lowestoft re-established for the 2024 general election.

Throughout its existence, the Lowestoft constituency covered the North-Eastern corner of Suffolk and, although encompassing some rural areas, drew the majority of its voters from the towns of Lowestoft, a resort and fishing port, and Beccles; it also included the smaller towns of Bungay and Southwold, with its brewing interests.

At the 1950 general election, Halesworth was once more placed in the revised Lowestoft County Constituency, but it otherwise underwent only minor changes to reflect local government rationalisations.

The constituency was revised in 1983 and renamed Waveney, as its new boundaries were now identical with those of the local government district of that name.

The re-established constituency, which came into effect for the 2024 general election, is composed of the following wards of the District of East Suffolk (as they existed on 1 December 2020): The bulk of the existing Waveney seat, including Lowestoft, Somerleyton and Beccles, was included in the re-established seat, whereas Bungay and The Saints were transferred to the newly created constituency of Waveney Valley.
