Lauren Bridgeman of Clash praised the album, stating: "each track possesses its own surge of mind movement propelled by the depth of eclectic sonics, psyche and contemporary wording".[2] Mackenzie Herd of Exclaim! wrote: "on A Lesson Unlearnt, the insights on love are articulated both from the position of the one being sought and the one seeking affection, offering an entry point for anyone who can identify with love's effects".[3] George Meixner of The Line of Best Fit concluded: "the variety of genres synthesised to generate this finished record show that they have absorbed life's lessons and reconstituted them to suit a unique outlook. The effect is a strangely familiar, yet singularly arranged thread of consciousness".[6]
In his mixed review for Uncut, Stephen Dalton stated: "while Winfield's pompous lyrics and over-earnest tone sometimes grate, the supple disco-funk of "Sparks" shows definite promise".[7]
