Neither would I.
But there is an enormous difference between not making the sale that you describe, and banning the sale of gas related items to non GSRs.
Just as an example, well over half, and probably as many as 75% of sales of gas boilers are not to GSRs.
Thats right - nearly three quarters.
But these are not irresponsible or dangerous sales. They are just sales that you aren't considering in your ban plan.
Manufacturer sells to merchant. Not GSR
Manufacturer sells to distributor. Not GSR.
Distributor sells to merchant. Not GSR
Merchant sells to another mechant. Not GSR.
Merchant sells to Council, Housing association, ministry of defence, university, hospital, housebuilder, indeed, any one of hundreds of perfectly legitimate organisations who have a right to buy and sell products freely in a free country, and without any intent of illegal fitting, and with zero risk to the public.
Its simply disproportionate to ban these transactions - many, many millions of them across all gas products - in order to acheive what? To drive the have-a-go hero to purchase a 2nd hand appliance on ebay (how do you police that?) and do something still more dangerous?
I agree with a lot of what you say.
A lot of those sales/customers you mention, are and have legitimate reasons for buying. For example, If you sell a thousand boilers to a building firm for a housing estate, fine, someone has to do that and I have no problem with it.
My Ban Plan Ray, is more concerned with the sales of boiler parts that goes on over the counter to people who are obviously going to go away and fix their own or other peoples boilers.
I realise that this ban is nigh on impossible and will never be attempted.
You must understand why there is frustration felt by legitimate GSR engineers who see Non registered people buying and installing parts.
The suggestions made by myself and others are born of that frustration.
