I am almost certain that the plant shown is a Streptocarpus. I would not make a guess to its identity. A number of the Dibley streps from the UK are well known for their long bloom cycle.
An excellent source of information is the following web page:

There is also a link to photos of many named plants. Hope this is of some help.
Regarding the leaves, I would make it a point when watering to keep them dry.
