Avon was abolished in 1996 both as a county council and a ceremonial county, being succeeded by the unitary authorities of Bath and North East Somerset, Bristol, North Somerset, and South Gloucestershire. The constituency boundaries used up to the 2005 United Kingdom general election were drawn up when the county still existed. For the review which came into effect for the 2010 general election, the four authorities were considered separately, entailing four seats for Bristol, three for South Gloucestershire and two each for Bath and North East Somerset and North Somerset. For the 2023 Periodic Review of Westminster constituencies, coming into effect for the 2024 United Kingdom general election, the Boundary Commission for England considered the area comprising the former county of Avon, together with Devon (including Plymouth and Torbay) and Somerset as a sub-region of the South West Region. The area is divided into 13 parliamentary constituencies – 6 borough constituencies and 7 county constituencies, including two which cross local authority boundaries with Somerset.

See 2023 Periodic Review of Westminster constituencies for further details. 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 "Avon" (covering the Bath and North East Somerset, Bristol, North Somerset, and South Gloucestershire council areas) with Devon and Somerset as a sub-region of the South West Region, resulting in significant change to the existing pattern of constituencies. In Avon, Bristol West, Kingswood and North East Somerset were abolished, being replaced by Bristol Central, Bristol North East, and North East Somerset and Hanham. In addition, Frome and East Somerset, and Wells and Mendip Hills were established as cross-authority boundary seats. The following seats were proposed: Containing electoral wards from Bath and North East Somerset Containing electoral wards in Bristol Containing electoral wards in North Somerset Containing electoral wards in South Gloucestershire

2010

Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to increase the number of seats which covered "Avon" from 10 to 11, with the creation of Filton and Bradley Stoke. This resulted in major changes to Kingswood and three of the four Bristol constituencies. A further three constituencies were renamed. (The maps on this page do not show the nominal extensions of several constituencies over the waters of the Bristol Channel.) Other former constituencies in the area were:
