Elections for the Royal Borough of Kensington and Chelsea were held on 6 May 2010. The 2010 General Election and other local elections took place on the same day.
In London borough council elections the entire council is elected every four years, unlike some other English councils, where a third of the councillors are elected for a four-year term in three successive years, with no elections in the fourth.
The Conservatives lost the Earl's Court Ward by-election in September 2010 to the Liberal Democrats and narrowly won the Cremorne Ward by-election by only 19 votes. Many commentators blamed the Conservative councillors led by Merrick Cockell for these poor results, stating that the council did not adequately take into account residents' views on projects such as the proposed Thames Tideway Tunnel and the Earl's Court building works.
