I agree with you about the equipment side.
Was pleased to see my Rug Doctor qualified

But I also have a superior piece of equipment also where the manufacturer did not have it tested, which would mean I would have to use my rug doctor.
A lot of us quote Shaw industries in our scripts etc, but I have read many variants from truck mounts to HWE (never rug doctor) as their preferred method.
Not being as knowledgeable of Carpet Suppliers in UK as I would like.
But on my visit to Carpet Shops in UK I cannot recall seeing product made by Shaw industries
If this scheme did come to UK perhaps full IICRC membership would be better than NCCA
At the risk of starting a debate it has been said before that IICRC is not a trade body but NCCA both give an industry training qualification.
