Storm Doors & Storm Windows in the UK

[Steve]

Don't know why this question suddenly came to me, maybe it's because
it just got cold here in Minnesota (lowest temp in the state today; -2F).

Do houses in the UK typical or ever have storm doors and storm windows
on them?

For those who don't live in cold climates, storm doors & windows are 
second doors and windows that go over the primary doors and windows to
help keep cold and wind out. 

It would be absolutely unheard of for a house in Minnesota to not have
them. Although, an alternative might be multi-pane windows with two or
three layers of glass. The storm door/window and the multi-pane glass
help insulate, so not only do they keep wind and cold out, but the
keep heat in and make your house much more energy efficient.

In the HP story and in most photos I see, storm doors and windows do
not seem to be the case in the UK. That's seems odd in a country that
appears to be concerned about energy efficiency.

Can anyone confirm or deny this???

Silly question, I know, but I'm curious. One of the largest storm door
manufaturers is located near my home town.
