The only organisation I would deem as necessary, is a true cost-effective non-profit making system inspection organisation that was tasked with checking every system and sorted out the real cowboys.
And isn't this the obvious role for the Fire Brigade ??!!
The problem we have now is that our potential customers don't believe a word we say, regardless of qualifications and memberships of third party schemes. So we end up in competition against one man bands who have never heard of 7273-4 or F-Gas Certification, detector head removal monitoring or search distances come to that.
Clients listen generally to who is going to cost them the least and promise them the most. While there is still no effective policing of the certification of new systems the cowboys can install what they want and sign their name on the back of a fag packet. The client is ignorant and doesn't care and no one is any the wiser till someone gets hurt and then guess what...... "we will all learn lessons from this latest disaster".
In the mean time the cowboy has ridden off to the Costa Del Sol in his new SLK and muggins lays awake at night worrying about connecting a latching relay to a sounder circuit.....
