I've got a blue plastic 25mm supply pipe to the house, but not very good flow rates or water pressure. It takes about 15-20 mins to run a bath and I certainly can't water the garden with a sprinkler.

The water board are coming out to investigate, but I fear there will be nothing they can do? I was thinking of installing a break tank and pump (http://www.arrowvalves.co.uk/productdetail.php?id=42). Does anyone have any experience of these?

In order to get a decent shower (or two) and a quick bath I was also going to replace my old Worcester 24i combi with a condensing boiler (in order of l/min at 35 C Worcester, Baxi, Glow Worm, Ferroli). If this produces around 15l/min of hot water and the cold is boosted by the above pump, will this allow 2 simultaneous showers?

The cold will not really come into the question (at least during the
winter) since the 15l/min figure is at about shower temperature without
adding cold. You may just get two showers at once out of it so long as
your shower head is not too thirsty, but there will be no spare capacity
in the supply, so if a tap gets turned on elswhere then someone (or
both) is going to get a cold shower.
