IME, certain garden hoses (hello Screwfix) fail early at 7.5bar, so for
anyone with 10bar static pressure, I would rate it as a *very good* idea
to
include a pressure regulator next to the stopcock. I found 7.5 bar a big
enough pain to include a regulator in my system. No real disadvantages and
a
decent device does not reduce the flow (I tested this specifically). CAme
in
very handy when I wanted to install a water heater that required 6bar
(the
included pressure relief valve is set to 6bar).

Cheers

That's a good point on hoses.

The "spur" to my outside taps is upstream of the pressure regulator.

It's a real hassle replacing hose connectors all the time (because they get
blown off). ....and have had one "burst".
