The annoying thing is that the previous owners had the feed pipe replaced (now 20mm plastic) which runs into my kitchen and then splits off via a dirty great big lead pipe running at the top of my kitchen wall into the neighbours house (I just replaced the last lead section in mine)! Also no stop cock on their side so if they want to isolate the water they need access into my kitchen! Why the previous owners didn't split the supply when they had the feed pipe replaced I really don't know. I assume that the new line runs along the side of the house which has now been built over (covered passageway) meaning my only realistic option if I want to split the supply via another feed is to use molling. From all of the suggestions/advice I have received on this thread, I think I may have to look at this option as it may be the best solution and be cheaper (I would do as much of the preparation as I could in terms of excavations at each end). Does anyone have a rough idea of how long an 8m "mole" would cost if as I said I did all of the preparation?

So, South East Water checked the supply today and at the house it is around 3Bar and 11L/min!. In the road, although the technician didn't measure it (didn't really need to as I could see the improved flow), he reckoned it was around 25L/min. So, it looks to me as though I need to investigate further the option of moling so that I can run in a new pipe and split the supply off from the neighbours!
A new separate mains pipe is the best option. Then you can fit a high flow rate combi. But!!! If this is too expensive or cannot be done for some reason, my previous advice still stands, and would be the most practical see as you have 3 bar static pressure.
As your water flow is poor on a shared mains, the best solution is a cold water accumulator with a high flow combi. Combis are a world away from what they were 15 years ago. Then you will have decent water flows, with only cold water storage.

Agreed- new mains pipe is the way to go if I can get someone interested enough to quote for the molding! I contacted three companies on Friday and not heard back from any of them yet! I assume/hope it's down to the current restrictions rather that the fact that I said I would dig the holes myself - we will see.
Stop a local water authority van and ask the guy if he knows someone who will run the new main, they usually do for a thank you from him.
