General plumbing advice

[nickw]

Guys need some info recommendations, trying to come up with a ballpark costing for the first fix on all the plumbing. Looking through various posts and trying to make sense of everything. I need to do the work to keep all the costs down. 

Water is from borehole now, not the original mains.

Is 10mm the norm for sinks/taps/loos

Hep20 pipe or other 

How much should I budget for connections to 5 sinks/3 loos/2 showers/manifolds?/runs are prob 10-12m runs or shorter from mains entry.

No idea whats good and or not, different recommendations on all posts it seems, I rather pay more for better stuff/longevity and of course ease of fitting.

Help!
