Ms Caroline Timmons:

On vacancy, it is not always clear because we have census data, GeoDirectory data, and the new Central Statistics office, CSO, electricity metering data. We now have a new vacancy survey, so the Department asked all the local authorities to look at the GeoDirectory data and pinpoint where those houses are. The local authorities have a particular app that they then go to the house with and fill in all the details. That is how they source the properties for CPO activation, along with their derelict house register.
