Hi, I'm putting in a new outside tap using 15mm soldered copper pipe.
While unlikely at this time of year, I am a bit worried it may freeze
in colder months if I forget to drain it. Obviously I could lag it,
but would simply putting in a short section of flexible hose, such as
that used for tap connections, help at all? Providing an expansion
zone so the pipe didn't burst...?
Not much - fair point. But it is in a fairly visible space - ton a
balcony - so ugly plastic pipework might be an issue since the run to
the tap is a meter or so. But you're right, its not a massive issue :-)

You missed the most important information. How much of this is going
to be outside? 5cm, 5m? How much inside?
You could always put draining it into your other regular plumbing
maintenance, such as operating valves every six months. You do
maintain the plumbing?
If it does freeze the length of pipe outside is critical. A very
short length of pipe outside means the ice can expand inside and
thus it is not likely to burst, not that I would recommend leaving
such a pipe filled.
Nobody has yet invented lagging that adds heat to a pipe. All it
does is slow down the rate of heat loss. If lagged pipes are not
used it is likely that they will freeze eventually.
