Mr. Brian Carroll:

There are a few points to come back on there. The Deputy is right in that there are certain groups of people and certain houses that are more challenging than others. Retrofitting the entire housing stock is a project that is to take place over 31 years. We have made a start. We have targeted 500,000 to be retrofitted by 2030. This will happen in a series of waves over the coming decades.

I did not make a note of the point the Deputy made at the end.
