Is there a series 5 of outnumbered being filmed?

There has been some speculation around a potential Outnumbered series 5, but thus far, no formal announcement has been made. The show's creator, Andy Hamilton, has indicated that he would be interested in revisiting the series, but he has also expressed concerns that the children actors have grown too old for their roles. Additionally, the BBC, the network that aired the show, has not formally ordered a new series. Therefore, as of now, there is no concrete evidence to suggest that Outnumbered series 5 is being filmed.
