Cheryl wrote the song with Chiara Hunter, Danny Casio, George Astasio, Jason Pebworth, Jon Shave and Nicola Roberts, with production by Mike Spencer.

The accompanying music video for "Let You" was filmed in Downtown Los Angeles, and features the singer dancing on rooftops and walking through the city, after pushing away a lover.

[3] Produced by Mike Spencer, the song sees Cheryl sing lyrics such as: "I let you lead me down the wrong track, now I've gotta own that" and "I gave you loyalty, you were on your knees".

[7][8] Rob Copsey from the Official Charts Company commented that the song could "pass for a Girls Aloud" track, noting its "80-style beats" and "slightly wonky" structure.

It premiered on the day of the song's release on Cheryl's official YouTube channel and depicts the singer dancing on a rooftop with a troupe of dancers and interacting with a partner.
