When does Big Brother 2025 start? Everything you need to know about the upcoming series

We don't have long to go until the new series of Big Brother starts.

This Sunday 28th September, the 2025 series will start introducing us to fresh faces, big personalities, and unpredictable twists.

Hosted once again by AJ Odudu and Will Best, the show will see a new group of housemates step inside the famous house, where cameras capture their every move.

With no contact from the outside world, they’ll face weekly challenges, public votes, and each other - all in a bid to make it to the final and win a huge cash prize.

As we wait for the series to kick off, read on for everything you need to know about this year's show, including what time the launch show starts.

ITV has officially confirmed Big Brother will be returning to our screens on Sunday 28th September at 9pm on ITV2. Bring it on!

The show will begin like always with a Live Launch show with hosts AJ Odudu and Will Best welcoming the new housemates into the house in front of a live audience.

ITV has said we can expect that this season we can "expect more new twists and turns, elaborate tasks, intense nominations and live evictions as the cast of Housemates go up against one another in a bid to be crowned the winner, and walk away with a life-changing cash prize."

The launch show will start at 9pm sharp and finish at 10:15pm.

The Big Brother 2025 cast will be revealed on the night. We'll update you as they're announced and be sharing our verdict on who's most likely to win.

Last year, 16 contestants from different backgrounds entered the Big Brother house. We expect to see the same amount of contestants this year, if not more.

Big Brother is hosted by AJ Odudu and Will Best.

The duo were announced as the joint presenters of ITV's rebooted series back in 2023.

AJ is known for presenting Married At First Sight UK's after show, Channel 4's The Big Breakfast, and various BBC events, including the Eurovision Song Contest.

Will previously hosted the 4Music show The Crush, Dance Dance Dance and Celebrity Coach Trip.

This year's show is expected to run for seven weeks, which is one week longer than previous ITV runs of the show.

Big Brother will air on ITV2 and ITVX.

And if you can't wait for the new series to start, all the episodes for the past two series are available to stream on ITX.

The last series was won by Ali Bromley, with Marcello Spooks finishing as the runner-up. Bromley was crowned the winner on 15th November 2024 after securing over 50 per cent of the final public vote.

Big Brother starts on Sunday 28th September on ITV2.
