Lists of UK singles chart number ones

The UK singles chart is a weekly record chart which for most of its history was based on single sales from Sunday to Saturday in the United Kingdom. Since July 2014 it has also incorporated streaming data, and from 10 July 2015 has been based on a Friday to Thursday week. As of 14 February 2026, 1,451 singles have reached number one. The chart was founded in 1952 by Percy Dickins of New Musical Express (NME), who telephoned 20 record stores to ask what their top 10 highest-selling singles were.
