yep RDCO scheme ....
been operational for over a decade, maybe 15 years or more ...
I used to have to do it every month -- Registered Dealer in Controlled Oils ...
based in Neecestle C&E offices
used to be 100 ltrs or more - full record of customer ... may well have reduced the quantity for compliance - I de-registered in 2012
I'll ask my oil guy if they've dropped the max 100ltr sale before full records needed?
