D.B.S.

Entertainers & Disclosure & Barring Service
 
'D.B.S. / C.R.B.'s are only required if children or vulnerable adults are being left unsupervised.'
 
(This was a quote from the DBS Newsletter)
 
Since Entertainers or Santa's etc aren't supposed to be left alone with children unsupervised they are not eligible to have a D.B.S. / C.R.B. done on them.  You can no longer apply for one. 
PLUS
A lesser known piece of information is that if you do apply for a DBS when someone isn't eligible you can be sued by the DBS
AND
If you look at a DBS/CRB when you're not entitled to, again, you can be sued by the DBS/CRB
