Quite honestly I was surprised because instinctively I would have expected

It's never especially bothered me because I have an IMI pressure regulator
taking the in-house pressure down to about 3 bar....however the regulator
started playing up recently causing the in house static pressure to increase
a lot which could be quite alarming when filling a kettle.

The regulator is now fixed....and I am just curious.

You are lucky we have only 1.2 Bar

Ouch, I'm surprised, are you sure of the accuracy of the measuring
device?

Most (metal) domestic plumbing bits are only rated to 10 bar. Plastic
and hot a lot lower. A little bell is ringing that says the maximum
mains pressure ought to be about 6 bar. See what the Ofwat site has
to say?

I expect the OP will be glad to hear that after 10+ years! (if they're
still alive!)

As this was all discussed back in 2009 I suspect it all been resolved by
now.
