Mr. Niall Byrne:

As a regulator, it is not really possible for us to say how many are not registered with us. If we knew how many were not registered with us, we should be taking steps to register them all. It is not a piece of information that is available to us. If people tell us about unregistered tenancies or properties where they think there are unregistered tenancies operating, then we follow up on those referrals.
