There is a certain matter conscience involved here.
Just because 'rules' are not followed or even ignored, doesn't mean they are wrong.
It is a law of the land that many domestic installations, of all kind, should be notified. If an electrician, for example, wants to bypass said law, it is up to them. If danger and problems result, let them take the consequences.......but if someone dies as a result, could they care a tinkers about conscience and taking blame?
Most of our customers request certification and, in domestic instances, registration with the local authority. So we do it, not just because it is required by law. After all, as an NICEIC member, we did everything else but register before it began. To me, it meant a lot more then.
To tell you the truth, I don't half see some crap work around....dangerous and extremely sub standard. Are those responsible scam registered or are they taking back handers in the pub? Or do they just refuse to bow to 'rules', lawful or not?
You pay your money, you take your chance, it seems......as usual....and that is getting more worrying by the day.
