Ms Jean Kennedy:

We do not know. We would be aware of some data coming through our electronic stamping system. However, we have not kept detailed records of that. If we have to update the register because there is another valuation date, we will do so at that stage. We do not know how many new houses have come on-stream at this stage.

Specific criteria are needed to establish the existence of pyrite and to provide evidence that a house is actually affected by pyrite. Some increased flexibility was introduced in this regard following the Thornhill report in 2015. We moved away a little bit from the insistence on having an actual certificate from an engineer and a laboratory analysis of the affected materials. There could still be houses that might have a low degree of pyrite and it might seem as if there is pyrite damage. However, they do not meet the level of damage required for the exemption.

There is currently no statutory basis for any exemption because of mica. It has not been examined so far.

As for Revenue taking on the television licence work, I am not aware that there has been any detailed consultation with Revenue on that. However, I do not know whether there has been at a higher level.
