Ms Lucia Crimin:

I can take that. The system, as it has been designed, since the commencement of annual registration, is that where a tenancy is not renewed annually, it is automatically removed from the system. That is the first thing.

Second, every single tenancy on our system now is unique and distinctive. The eircodes are mandatory since May of last year. That was part of the stabilisation programme we implemented. Mandatory eircodes mean that we have unique tenancies. As to when the tenancy ends, we have commissioned a piece of work where we are looking at a property-level analysis of our register. By looking at individual properties, we are seeing how long they are staying on our register and then when they are coming off. I expect that in the fullness of time we will be able to see if and how they come back onto the register. It is important to remember that annual registration was commenced only two years ago, so we are only now at the point with our data set at which we can commence this type of analysis. We expect by the end of this year to have much more to say about that.
