The Boundary Commission for England recommended that the county be divided into 18 constituencies. The proposed Aldershot and Basingstoke seats, more predominantly urban than as present defined, will be designated borough constituencies. These changes were implemented at the 2010 United Kingdom general election.

The Boundary Commission for England submitted their final proposals in respect of the Sixth Periodic Review of Westminster Constituencies (the 2018 review) in September 2018. Although the proposals were immediately laid before Parliament they were not brought forward by the Government for approval. Accordingly, they did not come into effect for the 2019 election which took place on 12 December 2019, and which was contested using the constituency boundaries in place since 2010.

Under the terms of the Parliamentary Voting System and Constituencies Act 2011, the Sixth Review was based on reducing the total number of MPs from 650 to 600 and a strict electoral parity requirement that the electorate of all constituencies should be within a range of 5% either side of the electoral quota.

On 24 March 2020, the Minister of State for the Cabinet Office, Chloe Smith, issued a written statement to Parliament setting out the Government's thinking with regard to parliamentary boundaries.[3] Subsequently, the Parliamentary Constituencies Act 2020[4] was passed into law on 14 December 2020. This formally removed the duty to implement the 2018 review and set out the framework for future boundary reviews. The Act provided that the number of constituencies should remain at the current level of 650, rather than being reduced to 600, while retaining the requirement that the electorate should be no more than +/- 5% from the electoral quota.

The Act specified that the next review should be completed no later than 1 July 2023 and the Boundary Commission formally launched the 2023 Review on 5 January 2021.[5] See 2023 Periodic Review of Westminster constituencies for further details.
