Whenever mine do it, it is because I have allowed them to run short of water for a while. e.g. on purpose over winter, then suddenly started watering them. It is cured by more water and a bit of fertilizer, but be patient. If that doesn't work, restricting light as well, e.g putting under a tree for a month helps.

Your may not be the same thing of course.

If it is a Maurellii, it will not produce pups except occasionally as the parent dies following flowering and at no other time. Ensete do not produce pups except occasionally immediately following a flowering. They grow too high to bring indoors long before they flower, so unless you have access to a giant greenhouse e.g frined at a botanical gardens, it will not flower in the UK.
