"Slow" was critically acclaimed by
music critics. Ethan Brown from
New York praised the production of the song and commented "Everything at the top of the pops should sound as good as Kylie Minogue's "Slow"". He further felt that most of the songs on
Body Language "mimic its sound, [though] none of the other songs on
Body Language come close to the achievement of "Slow" and concluded that ""Slow" should be a template for pop singers who fancy themselves aesthetes". Adrien Begrand from
PopMatters commented that the song was "one of the strongest singles" of Minogue's career, praising her minimalistic approach on the song and its simple arrangement. The
Spin magazine review of the song complimented Minogue's vocals, saying that they will "
bring all the boys to the yard". Eric Seguy from
Stylus Magazine favoured Minogue's demanding vocals, saying that the listener "is open to Kylie’s demands, and willing to resort to any means necessary to impress her". Sal Cinquemani from
Slant Magazine felt that the song is one of the "few of the tracks on
Body Language approach(ing) the club-thumping zeal of
Fever". Olive Pometsey from
GQ deemed it Minogue's best and most "seductive" track, concluding that "featuring breathy vocals over seductive synths, it's the kind of song that would soundtrack that moment when you accidentally lock eyes with a hot stranger in a club perfectly [...] is indeed a slower track, but don't write it off that reason".
The Abbey Road Sessions' version of the song also generated a favourable response. Tim Sendra from AllMusic enjoyed the "sultry trip-hop take" on the song and picked it as a highlight on the album. Philip Matusavage from
MusicOMH appreciated the song's jazz influences, noting that it "suggests that Kylie and jazz could make for great things". Jeff Katz from
Idolator singled out the song as the "Most Surprising Reworking" on the album.
Jude Rogers from
The Quietus, however, felt that the song does not "respond well to this (orchestral) treatment".
Accolades and recognition Sal Cinquemani from
Slant Magazine included "Slow" on his list of "Top 10 Singles & Videos of 2004" at number five, calling it "one of the hottest tracks of the year." At the 2004
Ivor Novello Awards ceremony, "Slow" received a nomination in the categories "Best Contemporary Song" and "International Hit of the Year", but lost the awards to
Amy Winehouse's song "
Stronger Than Me" and
Dido's song "
White Flag", respectively. At the
47th Grammy Awards ceremony held in the year 2005, "Slow" was nominated for "
Best Dance Recording", but lost to
Britney Spears's song "
Toxic", which was originally written for Minogue. In order to celebrate
Valentine's Day on 14 February 2012, UK copyright collection society and performance rights organisation
PRS for Music compiled a list of the top ten "sexy songs" and placed "Slow" on the top of the list. In 2012, Minogue picked "Slow" as her all-time favourite song from her
25 years in music; in 2023, she cited the song as a reference point for her album of that year,
Tension. Writing for the
Herald Sun, Cameron Adams placed it at number 5 on his list of the singer's best songs in honor of her 50th birthday, calling it "'
Can't Get You Out of My Head's emo cousin – also with a deceptively simple electronic pulse, but taking a much darker tone [...] vocally Kylie moves from detached to carnal in the space of a verse, and somehow ["Slow"] sounds like everything and nothing is happening all at once". ==Commercial performance==
