In an ideal world. For 2017, CBB19 should be a regular series (lasting 5/6 weeks) with new celebs, same with BB18 being just a normal series (12+ weeks with NO CBB after) then in 2018 with it being the last year of Channel 5's contract the series will be confirmed to be axed again with CBB20 being a "Celebrity" all-stars in January (lasting 6/7 weeks) with the "civillian" BBUK all-stars in the summer lasting 100 days, being the final series of Big Brother UK on Channel 5.

Then in say April 2020 Channel 4 or ITV/SKY confirm they have bought the rights to the show and it will return after a three-year break in June 2021.
