I have read various articles on how to over winter your chilli plant but
to be honest my Habanero are still healthy and producing fruit.

At what temperature are you keeping them?

The fruit is ripening when they are tiny though and some are not much
bigger than a pea but the plant it producing flowers and tiny fruits
quite happily.

If you keep a grow light on them for 8 to 12 hours a day, the peppers
will be larger.

Question is, should I still prune it right back or should I just allow
it to keep doing it's thing in the hope that it will grow bigger and
juicier fruits once the longer, warmer days arrive in spring?

It really depends on the type of Habenero. I'd definitely cut back a
Bhut Jolokia, but not a Red Savina.
