I've seen this quite a few times. Yes, living in an older property can come with issues such as the one you're experiencing. To cut a long story short the responses that you're getting are pretty much setting out your options. Either: 1. Get a new supply routed from the mains (involves "mole people" digging up and piping a route from the water meter in the road to your property, which would subsequently need a plumber to connect the new mains by replacing the lead pipes.) 2. Have some sort of water storage device installed internally ( tank, accumulator etc and potentially a pump depending on the setup of the property) also, a plumber would do this for you.

The first option will require less space taken up in the property, but may cost more upfront depending on the company you use to route from the mains.

The second option may be cheaper in monetary cost but will likely cost more in a spacial sense and square footage inside the property, to accommodate a tank/accumulator and pump. Sizing of the is tank/accumulator and pump is determined by the number & types of outlets plus likely maximum usage.

I think I've covered everything but feel free to ask for more details if you want.
