Saw this on a different forum a few days back.
As of last Friday, Burnden Leisure had a D&B recommended limit of £500k, so looks like a lod of b0llocks to me.
We used to use Riskdisk for credit ratings - it's pretty much the cheap option (which is why we used it) and imo not very good. Also broadly follows D&B / Experian etc which is why I think that this is either b0llocks or RD after a bit of publicity.
I think I saw reference somewhere to them having only 100 employees. I can't see them exactly leaving no stone unturned on the research front with that size of a company.
