1. Check both hot and cold are being fed from the mains - your hot water
through the combi will be mains, but your cold may still be from a tank
(like the hot was, presumably). You could install a pump to bring the cold
up to a similar pressure, but it would be better to replumb the bath/shower
to run directly from the cold mains. You could keep the loft tank for the
loo cisterns (possibly quieter filling, and also a reserve in case of mains
water failure).

.... then when both the hot and cold are similar pressure ...

2. Fit a proper thermostic shower mixer
