Default Another exterior wiring question

As I mentioned on another thread, I'm planning on wiring up some
exterior lights and an exterior socket. I'm wondering what to do about
the short lengths of cable that will be exposed in both cases.

Just to summarise what I'm planning:

- I intend to drill through the wall of an outhouse to feed the
socket.

- I am planning two PIR-controlled lights. Again one will be on the
wall of the outhouse, so I will just be drilling directly through
the wall. The other is a few metres away on the side of the main
house and I am planning to run the cable in heavy duty PVC conduit
(the outhouse is attached to the house).

Based on advice I received on this group a few months ago (I'm pretty
slow at getting around to these things!), my understanding was that it
was OK to run standard T&E cable in the conduit as the conduit would
protect it from weather and knocks.

However, now that I have received the stuff I ordered I see a
potential problem - it seems like it is going to be difficult to avoid
having at least a few cm of cable exposed between the conduit and the
PIR entry holes. I can't see a way of getting a good seal between the
conduit and PIR. The lights themselves are less of a problem as I
can see a way to join the conduit to the light housing.

There is a similar problem with the fittings mounted on the outhouse
walls: even though I can drill through more or less directly where the
fitting is mounted, again there will be a few cm between the hole in
the wall and the entry hole in the fitting. (I haven't bought a socket yet
but the ones I've looked at in Wickes have their cable knockout holes around
the sides of the fitting, but none in the back.)

So, in summary:

- Should I be worried about these exposed lengths of cable?

- Is there some way I can weatherproof/protect them?

- should I not be using standard cable after all, but
something weatherproof instead? (This would be a pain as I've
already bought the cable etc. for the job.)
