The UK Rock & Metal Albums Chart is a record chart which ranks the best-selling rock and heavy metal albums in the United Kingdom. Compiled and published by the Official Charts Company, the data is based on each album's weekly physical sales, digital downloads and streams. In 2018 to date, 20 albums have topped the 25 published charts. The first (and to date most successful) number one of the year was Concrete and Gold, the ninth studio album by American alternative rock band Foo Fighters, which spent the first three weeks of the year atop the chart.
