I wish to put a shower at the opposite end of the bath to the taps,
consequently I need to run cold water mains under the bath and up the wall
at the opposite end.
Can I convert from 15mm copper to pvc pushfit using a tee, run a flexible
pipe under the bath then convert that to a chromed copper pipe to run up the
wall to the shower.
What are those conversion tee,s called and where can I purchase one?

Just use a standard compression joint and use the correct insert for the
plastic as recommended by the pipe manufacturer. No need for a special
conversion fitting.

Yes, this is all feasible.
I assume that that the cold feed to the bath is at mains pressure, and that
you're planning to install an electric shower?
As far as tees go, you have a choice - and you don't need any special
conversion fittings. The easiest is probably to use push-fit all the way, as
this will work with the existing copper pipe and with the flexible plastic
pipe. [Don't forget the insert in the end of the plastic pipe, and the cut
ends of the copper pipe must be spotlessly clean].
Equally, a conventional compression fitting will work on both types of
pipe - again with an insert in the plastic pipe.
Do you *really* want an electric shower? If you have a source of stored hot
water, you'll get a far better flow by using a mixer shower with a booster
pump - taking the hot feed from the bath supply(**), and the cold feed from
the cold header tank.
** Purists will tell you that you should have an independent hot feed from
the hot cylinder - but this is often not necessary.

Can the pump go under the bath?

Mine did. Although the hot water cylinder was in the adjacent airing
cupboard. The pump should be as close to the cylinder as you can manage,
really.

Yes, mine is too - and I've taken the hot feed from the 22mm feed to the hot
bath tap rather than going back to the cylinder - and it works fine.
