ITV’s Big Brother is set to return in autumn 2026 for what outlets describe as its longest series yet. Multiple reports say the new run is extended by seven days, bringing the total length to eight weeks. The articles also state that the upcoming series will include a mix of civilian housemates and former Celebrity Big Brother stars, marking their return to the main Big Brother house for the first time in this format. One outlet specifically names Gemma Collins among the former celebrity contestants said to be in talks to join the civilian group. The reports do not provide further confirmed details about the full cast or the exact launch date beyond referencing that it has been “revealed,” nor do they outline additional changes beyond the longer schedule and the inclusion of returning celebrity figures. Overall, the common points across sources are the autumn 2026 return, the eight-week duration, and plans to combine civilian participants with selected former CBB personalities.
