New CU but no water bonding...

Might have to up my estimate to 145 posts at this rate.

Your obviously poised to make a definitive statement.

I realise the OSG is just a guide but it does state in section 4.5 (the green one) that there is no requirement for Main bonding if the incoming service is in plastic.
If there is metal installation within the premises (and plastic incoming) it suggests there should still be Main bonding unless the metal work doesn't test as extraneous.

Smart Arse.

As an aside, if you don't bond the metal pipe work (after plastic), you'll probably or may have to supplementary bond incoming metal pipes into special locations, perhaps

if the pipework entering the bathroom is not extraneous and all circuits meet their requirement for disconnect times and rcd protected they would be no need to supplementary bond pipes anyway

Protective bonding works with protection a

Forgetting ancillary earthing, boilers etc. How likely are those pipes effectively be bonded to earth? I would suggest, apart from following like sheep, that's the most cost effective way of following reg 528.3.4 that most installs I've seen, seem to follow?

A measurement can be made to verify the effectiveness of the pipework connected to a main protective bonding conductor

where doubt exists regarding the effectiveness of supplementary equipotential bonding, it shall be confirmed that the resistance R between simulataneously accessible exposed-conductive-parts and extraneous-conductive-parts fufils the following condition

R =<50 V/Ia in a.c systems
Or
R=<50v/IdeltaN for rcds
