The following is a list of songs that have charted for 100 weeks or more in total on the UK Singles Chart Top 100, according to the Official Charts Company (OCC).^[1] The chart here is as recorded by the OCC, i.e. usually a Top 50 from 1960 to 1978, Top 75 from then until 1982, and Top 100 from 1983 onwards. In the pre-digital age, records with re-recorded vocals (for example, live versions) and Remixes released with substantially different catalogue numbers did not count towards the total and were seen as new hits (see "Blue Monday" as an example). In the digital age, if versions of a record are substantially the same tune, whether the release is remixed, live or re-recorded, they are combined under one chart entry, unless the record company has requested a version to be listed as a separate entry.^[2][3]

With over 380 weeks in the chart, "Mr Brightside"^[4] by the Killers has had more weeks in the Top 100 than any other single in over 70 years of chart data,^[5] and is also now in second place in the Top 75 long runners list (as previously used in The Guinness Book Of Hit Singles). "Someone You Loved" by Lewis Capaldi currently leads this list, with the song having been in the Top 75 for a few months longer than the records in the runners up position. Last Christmas has spent the most weeks in the Top 3. All I Want for Christmas Is You has spent the most weeks in the Top 10 and Top 40. When only a Top 50 was compiled, Frank Sinatra's "My Way" set a record which still stands: 122 weeks in the Top 50 between April 1969 and January 1972. It also held the record for most weeks in the top 40 with 75, until The Pogues' "Fairytale of New York" achieved its 76th week in the region in 2021 and most weeks in the top 75 with 124, which was surpassed by Ed Sheeran's "Perfect" in 2021.

The longest unbroken run in the Top 100 is 105 weeks for “Blinding Lights” by The Weeknd, which also holds the longest consecutive run in the top 75 (103 weeks). Engelbert Humperdinck's "Release Me" held the record run in the Top 50, at 56 weeks, for over 40 years^[6] until beaten by "All of Me" by John Legend with 58 consecutive weeks in the top 50 (since passed by "Thinking Out Loud" with 63 weeks). The song with the most weeks at No. 1 is "I Believe" by Frankie Laine which stayed in the Top 10 for 35 weeks, 18 of them at No. 1 and a further seven at No. 2. Also noteworthy is "Rock Around the Clock" by Bill Haley & His Comets, the only song released in the 1950s to appear in the lists, which achieved 36 of its weeks when only a Top 20 or Top 30 were published.

In the pre-digital era, Christmas-themed songs were often re-released in different years and several have continued to chart each year from the mid-noughties onwards. "Merry Xmas Everybody" by Slade has had 27 chart runs in 30 different years (1973–74, 1980–87, 1989–90 and 2006–23), while "Fairytale of New York" by the Pogues and Kirsty MacColl has reached the Top 10 ten times and spent a record 70 weeks in the Top 20 and 84 weeks in the Top 40. In a similar but more modest way, since 2007, "Thriller" by Michael Jackson^[7] and "Ghostbusters" by Ray Parker Jr.^[8] have charted at Halloween in fifteen and thirteen years, respectively.

The numbers shown are up to the chart for week ending 11 May 2023.

29 songs have spent 20 or more weeks in the Top 10 of the UK Charts. "All I Want for Christmas Is You" by Mariah Carey holds the record for the most weeks in the Top 10 history with 44 weeks. "Last Christmas" by Wham! holds the record for the most weeks in the top 10 by a British act with 41 weeks. "I Believe" by Frankie Laine holds the record for the most consecutive weeks in the top 10 with 35 weeks. "Fairytale of New York" by The Pogues featuring Kirsty MacColl holds the record for the most weeks in the Top 10 without reaching number one with 33 weeks.

The Top 40 chart has been broadcast weekly on BBC Radio 1 (currently as The Official Chart) since 12 November 1978 and is often referred to as 'the charts'. Appearing in the Top 40 can greatly increase a song's exposure on television and radio. "All I Want for Christmas Is You" by Mariah Carey holds the record for the most weeks in the Top 40 history with 87 weeks. In June 2015, "Thinking Out Loud" by Ed Sheeran became the first (and so far only) single to stay in the Top 40 for 52 consecutive weeks – equivalent to one year,^[38] having spent a record-breaking 18 weeks in the chart before reaching No. 1.^[39]

The Top 75 was published each week by Music Week magazine until March 2021 (when it became a monthly publication),^[50] with records reaching the top 75 described as hits (as in the case of The Virgin/Guinness Book of British Hit Singles). Since March 2021, the Official Charts Company have compiled a monthly Top 75 chart countdown for the publication. In regards to the weekly chart, the longest continuous run in the Top 75 is 103 weeks for "Blinding Lights" by The Weeknd (December 2019 to November 2021). In 2014, "Happy" by Pharrell Williams and "Let It Go" by Idina Menzel became the first singles ever to stay in the Top 75 for a whole calendar year, since also achieved by “Blinding Lights” in 2020. Frank Sinatra's "My Way" held the record for most weeks in the top 75 for nearly 50 years until it was broken by "Perfect" in 2021. ^[4]
