My Big Day received a score of 86 out of 100 on review aggregator Metacritic based on four critics' reviews, indicating "universal acclaim".[2] David Smyth of the Evening Standard called the album both "a star-studded surprise" and "an album that is excellently suited to the impatient streaming generation. It's 11 bands for the price of one".[4] Rishi Shah of NME described it as having an "unwavering sense of adventure" and felt "the results are as eclectic as [its guest vocalists] would suggest", concluding that it is "a creative milestone in itself" as well as "a far cry from the four-to-the-floor, teenage guitar band that a whole generation grew up with".[7]

Reviewing the album for The Line of Best Fit, Lana Williams summarised it as the band's "most unpredictable and utterly impressive album to date" as well as "vibrant, joyous, and completely delectable".[5] MusicOMH's John Murphy wrote that "although much of the album is still very recognisable 'Bombay Bicycle Club', it also takes many unexpected turns" on account of its guest vocalists, also dubbing it "the sound of a band off the leash".[6] Lisa Wright of DIY opined that it is a "record that feels effortlessly comfortable in its own skin whilst still managing to tread new ground" and "the best the band have ever sounded".[3]
