At a guess Chewy I would say they are a Habanero of some shape or form, maybe Paper Lantern , but most likely this One
They definately wont be naga heat levels, the smoothness of the pod itself is a give away, and they will certainly have a more fruity taste, making it a lot more edible and perfect for a Jalfrezi type curry, although I would still prefer the naga in mine 

You could turn them into Bonsai plants Naga, its what Im planning to do next year.

Overwintering would be a great Idea, giving you an early start next season and enough time to get the fruit ripe.
I overwintered a naga plant the other year, by the time it was warm enough to put plants in the greenhouse it was massive! Struggled to get it through the door

Not Serrano

Had a slow start here too, but the recent heatwave has really brought my plants on but still need a good few weeks of sun to ripen them up.
Are yours in a greenhouse Keith?
Climate and watering are key to a good crop, ideally temps shouldnt drop below 16C, impossible in Britain really, and over-watering slows growth. I always water fom the bottom which encourages the roots to grow down. Also I gently shake the plants a couple of times a day to help the plants polinate.

and a few more

A few of this years plants

All looks delicious Gav but you forgot to invite myself and George

It's a bit like train surfing or eating magic mushrooms. .

I have no idea on train surfing but the magic of magic mushrooms may well be beneficial in more ways than one according to the BBC
