Welcome to the Jungle received mixed to positive reviews from contemporary music critics, who commended the group as a whole and their originality, whilst some felt they had not yet "found their sound". Ally Carnwath of The Guardian called the album a "mixed bag, front-loaded with singles and with the requisite number of formulaic club bangers, but also containing some flashes of personality and nicely executed ideas". Stoke Sentinel was more positive, saying that the album "has even more to give [with] no filler tracks here". Helena Ho of "Renownedforsound.com" gave the album 3 out of 5 stars and bemoaned its tracklisting, but she complimented individual tracks and called it "a solid debut from Neon Jungle, with a lot of ... standouts".
