Twxt. I'm assuming you are not self employed and not reliant on work to feed your family.
You are right, I'm not but I am and have been in the electrical industry as an electrician and later in electrical design/project management etc for many years. If you think I would notify and pay to let someone else inspect my work in my own home you dead wrong. I am qualified and competent to carry out my own work and issue the relevant certificates as required. Part P is a scam. Even the government have watered it down now because it does not work. All it has done is create hundreds of Electrical Trainee cowboy wanabees who have been on a short course because it has been sold to them as an easy industry to make money in. I have had them on my sites and also had to throw a couple off as their work was dangerous. Most have no previous experiance and come on here for advice to change sockets (but they can self certify). They are seen as legitimate because they are a member of a scheme. Part p has destroyed the electrian trade. I think that says it all.
