I acquired a Dahlia Tree in May. I have grown mightily but not flowered
much. One or two branches have split off (wind damage I guess). What
do I do now that winter is approaching. Not sure whether to prune at
all. Any advice appreciated. This is my first posting. Bit of a
novice with website discussions. Thanks in anticipation.

Lets start with a couple of questions.
Where are you growing this Tree Dahlia? (What part of UK }
Do you have a picture of the said Tree Dahlia?
What sort of soil do you have?

What you have is a tree dahlia, not a dahlia tree, and as such you
treat it as you would any other dahlia.
I will answer mor fully when You post the information requested.
