Re: Software Engineers
@"wiring in a new fixture can only be done by a licensed electrician" in the UK adding an additional circuit requires "competence".
Certification of competence can be obtained via a third party such as NICEIC, by holding a recognised Engineering qualification to NVQ level 3 or alternatively they can argue and win recognition in court for each installlation.
As to being "Chartered" this only means something if the professionals agreeing that you are competent are themselves competent and legally liable for miscertification.
Personally I would prefer that certification for competence was limited to those bodies who do not get paid to certify unless they are also legally liable for their failures.
