Star of the show Cillian Murphy confirmed when it will begin during an interview with The Birmingham Mail.
Series 3 of the show aired in May of this year, after a shooting schedule which started in January.
This suggests that series 4 will eventually make it to screens in autumn of 2017, meaning fans will have to wait a while to find out what happens to Tommy Shelby and co.
Peaky Blinders follows the misdeeds of the titular crime family, trying to expand their enterprise in the aftermath of the First World War.
In the interview, Murphy said he was happy with how popular the show has become all over the world.
“The success of it is down to really great writing. People in America love it, people in Australia love it, people in Poland love it - it's mad."
Peaky Blinders has been confirmed to run for at least 2 more series, with series 5 already being planned for the future.
Talks of a feature film have also been present, but this has not yet been confirmed. Murphy said he was unsure whether the show would work in a film format.
“I'm sort of ambivalent about it. I'm sort of like, 'Eh, yeah, I don't know, I'm not sure'. I love the idea sort of theoretically, but it has to come at the right time, you know? You can't alienate the beautiful democratic thing of television where everyone just watches it."
Peaky Blinders series 4 is due to air next year, with the first 2 series available to watch on Netflix right now.
