Chelsea and Fulham is a constituency represented in the House of Commons of the Parliament of the United Kingdom. It was first contested in the 2010 general election.
Following the review of parliamentary representation in west London, the boroughs of Kensington and Chelsea and Hammersmith and Fulham were paired for constituency allocation purposes, and allocated three seats between them.
This broke the previous pairings of Hammersmith and Fulham with Ealing, and Kensington and Chelsea with the City of Westminster, and the end of the former constituencies of Hammersmith and Fulham and Kensington and Chelsea, as well as the cross-boundary seats of Regents Park and Kensington North and Ealing Acton and Shepherds Bush.
Kensington was recreated as a stand alone constituency. The same happened to Hammersmith, previously part of Hammersmith and Fulham.
