It seems the length depends on how the previous series rates so starting with BB14:

-BB12 & 13’s ratings were disappointing for C5 at the time, so BB14 was 68 days
-BB14 rated 0.3m higher than the previous, so BB15 was 72 days, the longest C5 series
-Then after BB15 decreased from BB14 by 0.3m, they reduced BB16’s length to 66 days
-After the lowest ratings ever at the time for BB16, 1.4m, BB17 was made the shortest series ever at 50 days
-However after an improvement in that series with it rating 1.6m again, BB18 was increased to 54 days

But because BB18 is now the lowest rated series ever were probably looking at about 42 days lol

It got increased to 54 days so that it would not confilict with the Love Island finale, which was Day 50 in the Big Brother house, I read somewhere.
I also read somewhere that BB18 could have lasted less than 50 days.

Bb12 launched with 2.77 million and had very healthy viewing figures with the finale getting 2.2 million viewers. Also the fact plus 1 wasn't on back then it did really well.

Bb13 was far more impressive launching with 2.93 million and a lot of episodes were pushing 2 million but we're heavily dented by the Olympics later on.

Bb19 imo will only be a 50 day run followed by a final CBB or ubb2 and that's all folks.

It's airing to late in the year for there to be another January series in 2019 to be aired only weeks after.
