Increasing hot water pressure

I have recently refitted my bathroom and fitted mixer taps, previous taps were single hot and cold. Ive noticed the hot water pressure is poor as its gravity fed. I have had to put none return valves on the hot supply to basin and bath as the cold water (rising main) was blowing the hot back down its pipe.The use of these valves has added further to the poor pressure though. I wondering what could be used to increase the pressure, i dont want to reduce pressure of the cold supply to compensate.

1. Raise height of tank feeding hot water cylinder.

2. Fit pump on hot water supply.
Thanks, what name would the pump go under and what sort of price are they.
Google on shower pumps UK will give you 1.7 million links to check out. Prices for single pump (hot only) £100+. Installation may be complicated - it's not just a question of sticking the pump on the existing hot pipe.
