If you search back, there have been a number of posts like this. The best reply that sticks in my mind came from the Special of the Location character, and went summat like:
I`ve decided that any worker working in my house is to wear pink overalls with pictures of bunny rabbits on. That is the "uniform" I have chosen. I am employing this person, and I can ask for anything I like as a pre-requisite; as can any other customer.
NICEIC were the "industry standard", before all the scam nonsense kicked off - it is now watered down to the point where almost anyone with half a brain cell, and enough money ( in reverse order of importance) can join a scam. There are STILL a lot of companies who know of the other providers, but request NICEIC. Anyone who did their homework before starting business knew this - and if your client base includes such companies, then NICEIC will be your scheme provider............... Which may be the reason some of us went that route - nobody ever REFUSES to employ NICEIC sparks en masse ; so I didn`t shut off any potential areas of work.
You pays your money, and takes your choice. That`s life.
