I may of got my facts slightly wrong, but I have been told that come January the UK Wholesalers.
Or at least the main one we use, are about to start policing the sale of refrigerants.
Meaning that unless you are known to them as working for a refcom or similar Company.

They will not sell refrigerant to you!
Apparently the wholesalers are to be made accountable for what refrigerants they sell and to whom!
There is even talk of software to track cylinders being issued to end users. Not sure about costs
But its a brilliant move all the same.
Has anyone heard similar?
