The UK Singles Chart is one of many music charts compiled by the Official Charts Company that calculates the best-selling singles of the week in the United Kingdom. Since 2004 the chart has been based on the sales of both physical singles and digital downloads, with airplay figures excluded from the official chart. Since 2014, the singles chart has been based on both sales and streaming; in 2018 it uses the ratio of 150 streams equivalent to one sale (not 100:1 as previously).

Chart rules were altered again from 7 July 2018 to help new artists break through by limiting the number of tracks by the same artist allowed in the chart at the same time to 3. The streaming to sales ratio remained largely unchanged but for songs which have spent a high number of weeks in the chart the ratio is altered to 300:1. This list shows singles that peaked in the Top 40 of the UK Singles Chart during 2018, as well as songs which peaked in 2017 or 2019 but were in the top 40 in 2018. The entry date is when the song appeared in the top 40 for the first time (week ending, as published by the Official Charts Company, which is six days after the chart is announced).

Two-hundred and eighty-two singles were in the top forty this year. Fifty-two singles from 2017 remained in the top 40 for several weeks at the beginning of the year, or re-entered during the year. "17 by Marc Kinchen, "Barking" by Ramz, "Beautiful Trauma by Pink, "Decline" by RAYE featuring Mr Eazi, "Feel It Still" by Portugal. The Man, "I Know You" by Craig David & Bastille, "I Miss You" by Clean Bandit, "Let You Down" by NF, "Man's Not Hot" by Big Shaq, "My Lover" by Not3s, "No Words" by Dave featuring MoStack, "River" by Eminem & Ed Sheeran and "Tip Toe" by Jason Derulo all first charted in 2017 but reached their peak in 2018.

Additionally "It's the Most Wonderful Time of the Year" by Andy Williams, "Merry Xmas Everybody" by Slade, "Rockin' Around the Christmas Tree" by Brenda Lee" and "White Christmas" by Bing Crosby all returned to the chart at the end of 2017 and rose to a higher position at the start of 2018, having peaked in previous years.

The list of singles that charted in 2018 but did not peak until 2019 include "Advice" by Cadet & Deno Driz, "Baby Shark" by Pinkfong, "Going Bad" by Meek Mill featuring Drake, "Hold My Girl" by George Ezra, "Mo Bamba" by Sheck Wes, "Nothing Breaks Like a Heart" by Mark Ronson featuring Miley Cyrus, "Rewrite the Stars" by James Arthur and Anne-Marie, "Ruin My Life" by Zara Larsson, "Sunflower by Post Malone and Swae Lee, "Sweet but Psycho" by Ava Max. A selection of Christmas songs which had charted in 2017 returned to the chart at the end of the year and reached a new peak for their latest run in 2019.
