2013 in British music charts

The UK Singles Chart and UK Albums Chart are two of many music charts compiled by the Official Charts Company that calculates the best-selling singles/albums of the week in the United Kingdom. Since 2004 the chart has been based on the sales of both physical singles/albums and digital downloads, with airplay figures excluded from the official chart. A total of 30 singles (1 of which claimed the top spot in 2012) and 35 albums (3 of which claimed the top spot in 2012) claimed the top spot in 2013.

Every song which reached number one between 27 April and 13 July sold over 100,000 copies during its first week of sales although it failed to break a record which was previously held in 1997 where the number one single would sell 100,000 copies or more in its first week of sales every week from 28 June 1997 through to 3 January 1998.

Album sales, however, were at an all-time low with only 93,200,000 albums sold. It was also the first time since 1984 where an artist studio album released in the same period, failed to sell over a million copies by the end of the year.

Following the release of David Bowie's comeback single "Where Are We Now", singles became eligible to chart, before the release of its parent album.

In the singles chart, James Arthur returned to the top of the charts, having reached number one in 2012 with "Impossible". Bingo Players, Macklemore & Ryan Lewis, Avicii, Nicky Romero, The Saturdays, PJ & Duncan, Duke Dumont, Daft Punk, Naughty Boy, Robin Thicke, Icona Pop, John Newman, Miley Cyrus, Ellie Goulding, OneRepublic, Lorde, Storm Queen, Martin Garrix, Alesso and Sam Bailey have all claimed their first number 1 single as a lead artist.

In the albums chart, Emeli Sandé, Calvin Harris and Mumford & Sons returned to the top of the charts, having reached number one in 2012 with Our Version of Events, 18 Months and Babel. Biffy Clyro, Bastille, Rudimental, Caro Emerald, Daft Punk, Disclosure, Tom Odell, JAY Z, Robin Thicke, Jahméne Douglas, Richard & Adam, Avenged Sevenfold, The 1975, Haim, Miley Cyrus and John Newman have all claimed their first number 1 album.

Emeli Sandé continued her chart success in the albums chart when her album Our Version of Events, which was the biggest selling album in 2012 was also the biggest selling album in 2013 throughout its entirety until it was surpassed during the final week of 2013 by One Direction's third album Midnight Memories, which ended the year as 2013's biggest selling album, pushing Sandé into second place.

"Blurred Lines" by Robin Thicke featuring T.I. & Pharrell Williams has spent the most weeks at number one in the singles with five and Les Misérables by Les Misérables, Our Version of Events by Emeli Sandé and The Impossible Dream by Richard & Adam have all spent the most weeks at number one in the albums with four.
