Hello all, thanks for the replies

Right - I don't think its any sort of CREATURE because the noise is now
pretty much constant AND It is only audible from my room and not any of the
others around

I am feeling then that it must he something in the attic moving around or
most likely the plumbing or something...the odd thing is when I went up
there (stuck my head in) i couldnt hear the sound - partly because if was
prob drown out by all the other nosie of the roads etc)

What about Central Heating? We get ticking noises (some loud, some
faint) around our house, as the pipes first expand and later contract,
as the CH goes on and off.

You can get that with plastic guttering too in sunny weather it expands
and contracts when it cools. But it is happening on cue at around 5 pm
IIRC, so it must be plumbing as was said early on in the thread.
