It was co-written by Joe Belmaati, Michaela Breen, Vince Clarke, Mich Hansen, Alison Moyet, John Reid, Remee and Ina Wroldsen. The song was produced by Belmaati in collaboration with Cutfather. The track samples a heavily synthesised backing rhythm from Yazoo's 1982 song "Situation".

"If This Is Love" was first released by Fascination and Polydor Records on 27 July 2008 as the lead single from Chasing Lights. It was accompanied by a B-side entitled "What Am I Gonna Do?", written and produced by Duck Blackwell and Paddy Dalton. The Saturdays collaborated with Ina Wroldsen on a number of songs; eight were chosen for the album. "If This Is Love" was then released as the first single from it. The song has prominent electropop and dance-pop genre characteristics. It contains lyrical influences from love-hate relationships, the definition of love and its complications that can result in situations of stalking.

"If This Is Love" received mainly positive reviews from contemporary music critics. On 3 August 2008, the single debuted and peaked at number eight on the UK Singles Chart with a total of just under 15,000 copies sold in its first week of release.
