OK .... so I gather it's probably just me but something I find hard to resolve ...
I don't know about anyone else but I haven't come across a customer who phones me and says, "Hi hotcrossbunny, please, I want one of those new fangled 17th Edition all singing all dancing consumer units that every plumber/carpenter/plasterer/
tiler/decorator/roofer/apprentice insists I need .....................and then said customer rejects the idea of replacing the borrowed neutral!
As I understand it, some interfering busybody comes along (most prob a plumber
) and tells customer that all is not well .... "I'm sorry to tell you this, but your electrics are not up to date. You need an "update"! Said customer, being mighty impressed, pleads with plumber for guidance and along comes PartP to the rescue ........ No doubt he/she(!?) has a "P" emblazoned on the underpants worn 'Superman' style ..... "Hi! Part P man (don't ask which part) to the rescue! ... What's your problem?" ... Hmmm,
Excuse the digression, but why is it ok as long as everything is 50mm beneath the surface? What is it that the plumber knows and I don't?????...
