I have 2 showers in my house. One in my en-suite and another in the family bathroom. Both showers have poor water pressure. Would i need a pump for each one, or will one do? The cold water pressure doesnt appear too bad so could i just use a pump for the hot water?

I also should have said you must pump both hot and cold gravity supplies to make the pressures equal. Shower pumps are equipped to do just this.
You could of course use power showers instead - again only suitable for gravity water supplies. Cheers!

Check out a website such as Screwfix and you'll find a selection of pumps and also the specifications of what they will do. Personally a 2 bar single pump is all you need. Bear in mind though you can't just take the hot supply from the usual top of the copper cylinder - pumps need to draw from an outlet lower than the top to prevent cavitation. An essex flange fitting is used to do this, but there are others.
