It was written by American songwriting duo Rick Nowels and Ellen Shipley.

Wilde travelled to Los Angeles to do three live tracks with Nowels, and during her time there, he played her "Love Is Holy", and she took to it instantly.

Mike DeGagne from AllMusic described the song as "bright and lively" with a "typical yet congenial" pop melody.

[2] Music & Media wrote that Wilde "has given up the bombastic leanings on some of her most recent work in favour of a more direct guitars-upfront approach.

[3] Simon Williams of NME noted that the track sees "Kim go for the shagfrenzy Belinda Carlisle approach".
