Well, I'm not Eng54, but I believe the answer lies with the insurance companies.
They have been badly hit by the financial disaster that is the current recession and will yet be hit again.
Their fight back is to tighten up on "business" policy wording.
Many policies now require PIR & PAT etc. if the client does not fully comply with all aspects of the policy then the whole policy is null and void, when this comes across to domestic then this will sort things as the insurer can specify that they require the work to be done by someone xyz etc. this will then force the insured parties to use competent persons.
There is a flaw in this, and that is for large commercial/industrial where by they have their own competent persons.
It will come and it is coming, and it has come in, it is just that a lot of insurance policy holders just don't check the small print, nor do their brokers/advisors!
Problem is why should our industry rely on it's standards being maintained by insurance companies. If an home insurance policy demanded a PIR every 5 years or whatever all that would happen is that another course would be opened up by the training centres and we would be getting the 40 pound PIR, in exactly the same way as we are now getting the 30p an item PAT, and so in effect demeaning the industry again.
All this was tried in the HIP and unfortunately the scheme was doomed to failure simply because it was too intense too soon, and of course the down turn in the property market.
There is no answer for our industry, it's all too late. There is no longer the coal mines, the industries, where guys were trained in all fields not just electrical, the UK no longer produces anything and so there are no opportunities to train kids today.
Successive governments have dumbed down our industry and segregated it into small blocks of training, domestic, fire alarms, PV, UPS, etc etc, which is why we have the problems we now have.
E54 as hit it on the head, we need to be licenced. The only organisation that is set up at this moment to do this is the JIB. I'm not advocating that they should do it, but I would rather have them do it that an affiliation of the scheme providers. Unfortunately IMO it's all too late, jobs in the training sectors, schemes, LABC would be lost and the government is not prepared to do that.
