I need to dispose of the use of electric shower in the bathroom of my apartment and want to fit a shower booster pump ,however the hot water supply is via an electrically heated combination storage tank the type where the cold feed is from an integral tank ontop of the hot storage tank. The HW pressure is very low and almost unusable and hardly flows from the kitchen tap. Is a pump available for this use.

Booster pumps are used when typical water pressure is too low and needs to be increased. There are various types of booster pumps available on the market, check the one which is most appropriate for your house.
