Basildon and Billericay is a constituency in Essex represented in the House of Commons of the UK Parliament. Since the 2024 general election it has been represented by Richard Holden, a Conservative.

History

The seat was created for the 2010 general election following a review of the Parliamentary representation of Essex by the Boundary Commission for England. It combined parts of the separate, now abolished, Basildon and Billericay constituencies. It has been held throughout its existence by the Conservative Party and, until the 2024 general election, with large majorities.

Boundaries

2010–2024

The Borough of Basildon wards of Billericay East, Billericay West, Burstead, Crouch, Fryerns, Laindon Park, Lee Chapel North and St Martin's. The seat merged about half of the previous constituency of Billericay with smaller parts of the former Basildon constituency – mostly around the centre of Basildon. The Billericay constituency lost Wickford to the new Rayleigh and Wickford constituency, and Pitsea to the South Basildon and East Thurrock seat, which also included the remainder of the Basildon seat.

Current

Further to the 2023 Periodic Review of Westminster constituencies, which came into effect for the 2024 general election, the composition of the constituency was expanded with the transfer in of the Vange ward from South Basildon and East Thurrock.

Members of Parliament

The MP until the dissolution of parliament in May 2024 was the Conservative John Baron, who had held the seat since its creation, but announced in October 2023 that he would be stepping down. His party's choice of the national chairman as its candidate to succeed him was controversially made just 48 hours before the deadline from a shortlist of one, to the anger of the local association.
