Thanks for all the replies.

I've ordered a couple of rolls of foam tape that looks like the Armaflex lagging
tape but is cheaper (and will no doubt be crap!).

The boiler room (where the store is) gets very hot inside; the surface of the
store itself is nice and cool so nothing much being lost there, so the room must
be being heated by the various "awkward" bits of hot pipework, and therefore
must be wasting quite a bit of energy.

The foam tape is only 3mm thick (as is the Armaflex stuff I believe) so I
suspect I'll want a few layers to keep the heat in properly.

Anyone know if CH pump bodies should be left exposed, or whether they can be
lagged too ?

Cheers
Lee
