A spokesman for the Channel 5 TV show said: “Due to the severe weather conditions, the Big Brother House experienced a flood.
“The housemates have been moved into The Other House temporarily. Everyone is okay.”
Evelyn Ellis, Sam Giffen, Emma Jensen and Andy West had been outside dancing in the rain when the water started pouring in through the living room ceiling.
They ran inside when they heard Lateysha Grace shrieking about the flood.
Property developer Jason Burrill ordered everyone to stand back before Big Brother said they were to stay in the bedroom while the show’s technicians tried to deal with the problem.
It was later decided to move them completely.
Presenter Rylan Clark- Neal tweeted: “Cant believe what I’m seeing. The @bbuk house has flooded! It’s literally Wet Wet!”
