Making their debut on the BAFTA-winning show are the likes of Frankie Boyle, Ghosts actor Kiell Smith-Bynoe and Canadian comedian Mae Martin.
Meanwhile, Jenny Eclair is returning to our screens for the new season alongside up-and-comer Ivo Graham.
Thankfully, season 15 won't be the last we see of Taskmaster either, with the show being commissioned for six more seasons as well as spin-off Junior Taskmaster.
But where is Taskmaster actually filmed? Here's everything you need to know about the Taskmaster house, which you can actually visit!

Where is Taskmaster filmed?
The Taskmaster house is filmed on the grounds and indoors of a property in Chiswick. Specifically, you can find the three-bedroom bungalow at Chiswick Bridge, Great Chertsey Rd, London W4 3U.
The property was previously listed for rent for £4,117 per calendar month.
Interestingly, during filming, the Taskmaster crew actually live inside the Taskmaster house.
"We move in and live here for the period of filming," director Andy Devonshire told us. "After season 1 I think they had some people come in and stay over the summer, but we de-Taskmaster it when we go away so it is very different."
He added: "There’s a different theme inspired by a specific artist every series so there’s obviously things that stay the same but we redecorate within the boundaries of that. When we leave it’s quite minimalist."
Taskmaster season 15 begins on Thursday 30th March on Channel 4 at 9pm. Looking for something else to watch? Visit our TV Guide and Streaming Guide to see what’s on tonight or check out our Entertainment hub.
