a) I would prefer to have a twin impellor pump fitted (under the bath?
use
redundant immersion supply?)

You could use the redundant immersion supply, or spur off a nearby ring
main. I would incorporate an 30mA RCD at some point in the circuit,
though.

although i'm presuming the pump isn't a standard one due to the low feed
pressure.

It would be a standard one. If you didn't have low pressure, you wouldn't
need the pump! If possible, it should be installed near the hot water
cylinder rather than the bath. It is better to push than pull. You may
find
you need to install a new flange on the cylinder if it starts drawing air
from the vent pipe. However, when I fitted one it was fine without the
flange. However, this is most likely if the cold tank is directly above
the
cylinder with short runs of large bore pipe.

b) Get the cold water tanks moved into the loft, would this provide much
pressure? it would give me some more space in the bathroom

This would help, but not suddenly provide an excellent shower, unless your
loft is many floors above. It would entail a large degree of disruption.

c) Get a normal electric shower or just a power shower fitted, requiring
new
pipework, 6/10mm2 cable installation etc.

Again, lots of work for little gain. Even a 10kW electric shower is not
very
good. It would also require good mains pressure.

So, in summary, the pump is probably the best option with the minimum
disruption. It will certainly give the best results, but may cause quite a
noise when on (but only comparable in amplitude with the noise of the
splashing water). It will also give good results on the bath taps.

If my shower head is raised as high or above the tank level will a normal
pump still be able to auto start?
i had a feeling there may be a problem here?
