The UK Indie Chart is a weekly chart that ranks the biggest-selling singles that are released on independent record labels in the United Kingdom. It is compiled by the Official Charts Company and is based on both physical and digital single sales. In 2009, the chart was published in the UK magazines ChartsPlus and Music Week, on BBC Radio 1's website and, from October, on the Official Charts Company's website. During the year, 20 singles reached number one.
