 Noughty by Nature was met with widespread critical acclaim from music critics. The Guardian scored the mixtape 4 out of 5 stars and noted the versatility on the mixtape, saying he achieved this under extraordinary circumstances due to a criminal behaviour order that prevents him from rapping about violence. The mixtape contains influence of early 2000's hip hop, with the writer saying "Digga is clearly trying to expand beyond drill to encompass trap and even pop balladry. This is sometimes to the album’s detriment. Its most thrilling moments come when it sticks fast to drill's minimal and now distinctively British blueprint, rather than looking back towards the US." 
 NME also rated the mixtape a 4 out of 5 stars, claiming it features some of Digga D's best and deepest work, saying "Once upon a time, Digga D's career was riddled with ifs and buts, yet he keeps growing musically, challenging what drill music can be. On Noughty by Nature, he confirms he's a genre juggernaut, but in wearing his heart a little more on his sleeve, he's also evolving right in front of us." Clash gave the mixtape a 9/10, calling Digga D an icon, saying the project "truly shines when he does what he does best. Speedy wordplay against a club-thumping beat is what makes this a memorable mixtape."
 In the United Kingdom, Noughty by Nature debuted at number one on the UK Albums Chart, with first-week sales of 8,855 album-equivalent units. The album had the lowest number 1 first week sales since Taylor Swift's December 2020, Evermore.
