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.

See 2023 Periodic Review of Westminster constituencies for further details.

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.^[5] 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 has proposed that the number of seats in Cambridgeshire be increased from 7 to 8, with the creation of the constituency of St Neots and Mid Cambridgeshire, resulting in significant changes to Huntingdon, North West Cambridgeshire, South Cambridgeshire and South East Cambridgeshire (to be renamed Ely and East Cambridgeshire).^[6][7][8]

The following seats are proposed:

Containing electoral wards in Cambridge

• Cambridge
• South Cambridgeshire (part)

Containing electoral wards in East Cambridgeshire

• Ely and East Cambridgeshire (part)

Containing electoral wards in Fenland

• North East Cambridgeshire

Containing electoral wards in Huntingdonshire

• Huntingdon
• North West Cambridgeshire (part)
• St Neots and Mid Cambridgeshire (part)

Containing electoral wards in Peterborough

Containing electoral wards in South Cambridgeshire
