Big Brother streaming up 32% as new series keeps viewers hooked

The launch episode for the new series of Big Brother has consolidated at 1.4m viewers. 

Big Brother returned to screens last Sunday on ITV2 and ITVX, and a dramatic first week in the House has kept viewers firmly hooked. Following the chaos of the Bov Boys takeover and the revelation that Tays has been secretly working as Big Brother’s mole, audiences are getting to know this year’s Housemates as tensions, friendships and rivalries begin to take shape.

From Sunday to Friday, the series has been streamed 4.9 million times, up 32% from 3.7 million over the same period in 2025. 

The second week of Big Brother is also seeing increased viewership, with both Sunday's and Monday’s episodes up 10% compared to the same episodes in 2025.

Big Brother: The Group Chat is also up 9% compared to last year's series of Big Brother: Late & Live.
