The following is a list of all albums that have spent at least 150 weeks on the UK Albums Chart as published by the Official Charts Company (OCC). The chart comprises a top 100 from August 1981 to 1988 and since 1994, a top 75 before this (and from 1988 to 1994) from 1978 and various lengths before this from July 1956. Re-releases – such as remasters, re-issues, deluxe versions or anniversary editions – are treated together unless the re-released version differs significantly from the original (for example, it has been re-recorded or remixed). This list does not include compilation albums by various artists, which have been excluded from the UK Albums Chart since 1989. Soundtracks are still included if they are an original cast performance or if all tracks are performed by the same artist.
