As a product of one of these courses I’d like to offer a little balance.
Three points
1. There is a niche that these courses fill.
2. There is massive over reach and over selling of the courses.
3. They enroll totally unsuitable candidates.
As far as the niche goes, and why I completed the course, there is much work in the domestic environment that require minor electrical work.
Installing an air source heat pump requires about 4-6 hours electrical work in a three day installation. The other two and a half days are general labouring, plumbing and building. All relatively low skill and labour intensive work.
The kind of fully qualified electricians that you can attract to this kind of role are no better than 5WWs. They’ve either been clipping new builds for 10 years and forgotten all they learned or believe core drilling is below their station.
Basically incompetent or bone idle.
Now if you have a reliable and semi-sentient employee these courses can fill the gap that allows you to trade in a safe and compliant manner.
There is no doubt these course providers BS candidates on what the course can give them.
Especially the initial verification and periodic T&I elements. These courses do not deliver sufficient underlying knowledge and practical experience to comprehend the results you get on testing. Personally I had to rely on support from family, my old man and brother are proper electricians, and watching endless JW videos on YouTube.
Some of those on the same course as me id not trust with a brush let alone an MFT.
So on balance, I’m more inclined to agree that they are scammers but, as always, the road to hell is paved with good intentions. There is a gap to be filled by these courses but the usual greed and self delusion has led to the corruption of a good idea.
