UK media regulator Ofcom received 44 complaints about the television series including complaints about violence, offensive language and child actors being involved in scenes of adult content. Thirty seven of the complaints related to a scene at the beginning of the third episode where a shooting takes place in a primary school. Channel 4 also received 28 complaints about the scene. It was aired a month after the Sandy Hook Elementary School shooting in Connecticut. A spokesman for Channel 4 responded, "Channel 4 thought very carefully about continuing with the planned broadcast of Utopia. The drama is in no way based on real events, and the scenes featuring violence are editorially justified within the context of the storyline. All material has been carefully considered in accordance with the Ofcom Broadcasting Code and we were satisfied that, appropriately scheduled in a late night slot at 10pm and preceded by clear on-air warnings about the graphic violence and very strong language, it could be broadcast as planned."
