Reminds me of when the Part P electrical legal compliance regulations came in.
o Part P was/is to ensure that only qualified electricians can make wiring changes in wet areas (kitchen / bathroom / etc)
o Do major major changes
o All changes had to use the new wiring colours and a certificate issued
o New wiring was in short supply and the cowboys bought up all the old wiring so they could continue their bad practices
No surprises there:
What got many Chartered Electrical Engineers (note not electricians) really pissed off is that we are professionally qualified to design electrical equipment, installations, be expert witness etc. BUT WE CAN'T even change a bathroom light ceiling rose!
