The full list of nominations for the TV awards recognises the Channel 4 drama – starring Years & Years frontman Olly Alexander – which followed the story of three young men in London in 1981 at the beginning of the HIV epidemic.
The awards It's A Sin is in the running for include best leading actor for Alexander, who starred as aspiring actor Ritchie Tozer in the drama created by Doctor Who and Queer As Folk writer Russell T Davies.
Davies is also recognised for his writing on the show with award nominations for best mini-series and best writer.
And Lydia West, 28, who played Ritchie's best friend and gay rights campaigner is in the running for best leading actress.
Alexander, 31, is nominated opposite David Thewlis for Sky Atlantic's true crime comedy-drama Landscapers; Hugh Quarshie for ITV's Stephen, about the murder of Stephen Lawrence; Samuel Adewunmi for BBC crime drama You Don't Know Me; Sean Bean for prison drama Time and Stephen Graham for Channel 4's Help, which tackled the care crisis during the coronavirus pandemic.
