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 retained Cambridgeshire as a sub-region of the East of England region, increasing the number of seats from seven to eight with the creation of St Neots and Mid Cambridgeshire. The town of St Neots was transferred from Huntingdon and the Mid Cambridgeshire areas, including the new towns of Cambourne and Northstowe, from South Cambridgeshire and South East Cambridgeshire. As a consequence, there were significant changes to the existing constituency boundaries, apart from Peterborough, which was largely unchanged. South East Cambridgeshire was renamed Ely and East Cambridgeshire.

The 2007 report of the Boundary Commission for England retained the same seven constituencies that had existed since the 1997 election, with minor boundary changes to align with current local government wards and to better equalise the electorates. These changes, which were implemented at the 2010 general election, included the transfer back of Thorney and Eye from North East Cambridgeshire to Peterborough, the return of the Cambridge ward of Trumpington from South Cambridgeshire to the Cambridge constituency, and small transfers of rural wards from North West Cambridgeshire to Huntingdon, and from South East Cambridgeshire to South Cambridgeshire.
