The Official UK Singles Chart reflects the UK’s biggest songs of the week, based on audio and video streams, downloads, CDs and vinyl, compiled by the Official Charts Company.

How is The Official Chart compiled?

• The Official Chart is the most comprehensive survey of its kind, almost a full market count in fact, it captures over 99% of all UK singles consumption, 98% of all albums and over 90% of all videos and DVDs.
• We count sales and streams from 8,000 sources every single day and then combine them all every Friday for the Official Charts, unveiled by BBC Radio 1 and published on OfficialCharts.com.
• The chart week counts sales and streams from 00.00 Friday morning through to 23.59pm on Thursday evening (this never stops, not even for Christmas.)
• Our aim is to reflect all the ways that fans consume music – across physical releases (CDs, vinyl, cassette etc.), downloads (audio, video, even NFTs), and streaming (audio or video).
• Because buying a single or album is different to streaming a track, we use a formula to combine all of this information: 100 premium streams (when you pay for a subscription) or 600 ad-funded streams are counted as 1 single ‘purchase’.
• For albums, we count the 16 most-streamed tracks from any album, and divide by 1,000 to create an “album stream” unit. Each of these units are counted as equivalent to 1 album purchase (whether download, CD or vinyl) for chart purposes.
• Sales and streams of all versions of a track, including for example remixes, acoustic versions, live versions, sped-up versions, are all combined together into one total and one chart position in the Official Chart.
