If I can't leave a circuit or the part of it I've worked on fully compliant with regs when I've finished my work then I walk away.
But if
you are not responsible for the installation of the circuit then
you aren't leaving it non-compliant.
If your position is that you will not replace accessories on any circuit which you could not certify complies with the regulations then does not logic and consistency lead you to the position that you can
never replace
any accessories because you can
never be sure that the circuit complies?
I'm not in the habit of doing favours and bodging non-compliant installations for the benifit of my customers.
I being the person responsible for the Design, Construction, Inspection & Testing of the electrical installation (as indicated by my signature below), particulars of which are described above, having exercised reasonable skill and care when carrying out the Design, Construction, Inspection & Testing, hereby CERTIFY that the said work for which I have been responsible is to the best of my knowledge and belief in accordance with BS 7671:2008, amended to 2011 except for the departures, if any, detailed as follows.
If the work for which you have been responsible is changing an accessory, not installing the cables which connect to it, what non-compliant things are you bodging?
It WILL come back to bite you.
If you replace a socket on a 32A ring final, and unbeknown to you (and totally undetectable by testing) part of the circuit consists of 0.75mm² flex, or deviates from the safe zones, why will those things not come back to bite you?
Am I going to risk my registration and my reputation, even my freedom just so you don't have to make your electrics safe? Am I heckers like.
Your freedom?
Your
freedom?
Really?
As in genuinely and reasonably and with just cause etc you
really do believe that you could actually be imprisoned if you changed a light switch where the sheath of the T/E cable supplying it had been cut back a couple of cm too far?
I have to say that if that is what you really believe I struggle to see how you are applying any intelligence or rationality to your decision making.
