How to make the shower over my bath more powerful?

I reckon the CWS could be lifted about 500mm but not much more as the roof narrows towards the top. The pipework is quite well laid out. It is a standard 2 storey house, the CWS is in the loft. There is no direct pipe to the bathroom, it goes down to the airing cupboard and then under the floorboards across the hall and under the bath, so yes it does go UP from the floor to the bath.

I am thinking that the inline pumps under the bath is my best option, it would cost about £200 and is DIYable as I can power it from a socket in the wall behind the bath.  It is also the least upheaval and the highest chance of improving pressure.

Do you know what a Surrey flange is? 

Is that the one Doris Day was singing about?  https://www.youtube.com/watch?v=2fOSMxyGomM

Yes I did look into a Surrey flange when we had issues with the ensuite shower when we first moved here, although I never took it any further as the issue was a faulty shower pump. I dont think I currently have one as I cannot see anything resembling one on my hot water tank.

Thanks for all your help and detailed explanations which have really helped my understanding.
