pipework and making good some of the excess notching.

I believe building regs require you to insulate pretty well all water
pipes nowadays, for economy reasons rather then frost protection.
This
does not adversely affect your second suggestion though.

Although I have insulated my pipes, I'd not be too worried about not
insulating central heating pipes upstairs - any heat lost will be
lost into the building.


Wrapping the pipes can prevent them rubbing against the joists and
hence creaking. I would strongly recommend doing it.

If it is purely for noise, then simply wrapping at the joist will do
that.

As I said, I have insulated my pipes, but only between the joists.
Where they pass through existing notches, there is just a very thin
layer of material to keep them from touching.

If you only do the bit where a pipe goes through a notch, expansion and
contraction of a number of years might 'relocate' it.

The slip-over felt-style insulation is cheap enough, surely ?.

I've never had that problem. I am pretty sure that the covering holds a
lot tighter to the rough wood than it does to the the smooth metal, so
stays in place well. The existing notches are pretty tight, so anything
going over the pipes has to be very thin.
