Gatwa follows SNL UK ‘s previous hosts Tina Fey, Jamie Dornan, Riz Ahmed, Jack Whitehall, Nicola Coughlan, Aimee Lou Wood and Waddingham.
The series was recently renewed for a second season of 12 episodes, which will start airing in Sky One from September 2026.
Speaking about the renewal news, SNL creator and executive producer Lorne Michaels said: “I’m incredibly proud of our team and the show. It keeps getting better every week. I’m grateful to Dana Strong and Sky for believing in and supporting SNL UK. I’m excited for the season ahead.”
