Correct.

I remain curious about the pressure/head being reported in the
original post. I suspect that most providers in UK don't supply
water much above 3, 4 or 5 bar.

That's the typical range.

Water co's do play about with pressure, if works are undertaken they
drop it down noticeably, then ramp it back up once complete. The
problem with 10 bar is water hammer (flexible w/machine hoses) is
going to get brutal on the pipework.

Water hammer occurs when flow is shut down suddenly. The water is not
compressible and has inertia. I believe that uPVC pipe has a safety
factor of at least 2 to protect against water hammer.
