The licencing only covers Key Holding/Security.
What this actually means, as i understand it, is, if you are one of the contacts that the police or other security firm are going to contact in the case of an emergency, then you need a licence, there are of course, as you would expect exemptions from this, however, if, as part of your contract, you are listed as an emergency contact, then you need to be licenced and properly insured for the risk, regards,
