Mr. William Walsh:

I want to add one or two pieces to both Dr. Byrne's and Mr. O'Mahony's comments regarding estate by estate. The solar PV scheme has been good for us in terms of our one-stop shop model. We have 800,000 building energy ratings, BERs. As an organisation, we have a geographic information system, GIS, map that shows where the low-hanging fruit is for many of these one-stop shops, and we will be able to provide them with intelligence-based information where they can go and knock on doors.

I will come back quickly to the solar PV scheme, where we have seen the installers who are working with us have been excellent at delivering this scheme and ensuring that when they go into an estate, they put up the sign locally that they are doing the work and their pipeline is driven by referral on the spot. The solar PV scheme was set up in recent years. We have had the opportunity to get some of the learnings we will implement with the one-stop shop.

There is a secret sauce, as it were, with solar PV. People are very interested in it. If we could get people as interested in retrofit as they are in solar PV, we would be absolutely flying. Those are merely some further comments I wanted to add to those of my colleagues.
