Turn It Up peaked at number six on the UK Albums Chart and was certified triple platinum by the British Phonographic Industry, with sales in excess of 900,000 copies.

[10] "Turn It Up" was released as the fifth single on 7 June 2010, for which a music video, directed by Nick Frew, was shot in Los Angeles on 17 April 2010.

"[15] Stephen Thomas Erlewine of AllMusic wrote, "Despite this fondness for swinging girl group sounds and Pixie's predilection for belting out the songs, Turn It Up doesn't play as a retro-soul throwback, the way Winehouse or Duffy do.

[17] Dan Cairns of The Sunday Times opined that "[b]ar two missteps ('My Love' and 'Nothing Compares'), Turn It Up is superior, infectious, expertly tailored pop that, had it been recorded 30 or so years ago, would very likely now be being praised to the heavens in reissue sections.

Music noted that "[t]he sass, swagger, killer hooks and big production have been focused on the obvious chart contenders and the rest of the album is, true to tradition, a lot of middle of the road balladry and overly earnest swaying, also known as filler.

"[20] Daily Express reviewer Robert Spellman felt that the single "Mama Do (Uh Oh, Uh Oh)" "promised what the album hasn't delivered, a sort sultry self-confidence with a pinch of the wreckless [sic] that would do Lady Gaga proud", adding that "corny power ballads such as 'Cry Me Out' and too much half-baked R&B mistakenly attempt to give Pixie depth when she—or rather her writers—should be gunning for surface only.

"[2] The Daily Telegraph's Helen Brown referred to Lott as "[f]un and feisty but hard to distinguish from the rest of this year's girl pop pack.

"[1] Imogen Carter of The Observer compared the album to a "Disney teen-movie soundtrack", calling it "cloying and cliche-ridden, particularly the slow numbers.
