Mr. William Walsh:

I will answer the Senator's first question and will refer to my colleague, Dr. Byrne, who can answer the Senator's second question on the social impact assessment. On our appearance before the Committee of Public Accounts and the numbers that we presented for 2020, I do not have the numbers to hand. From recollection, I can give the Senator a broad, general overview of where we were and how we operate as an organisation. Clearly, for us as an organisation, 2020 was a really difficult year to get into homes and to have people working. For a long time, our contractor base could not get into homes, nor did homeowners want them in homes, even after the lifting of restrictions. Momentum stalled, from that perspective. We were not in a position to fully expend the budget that we had over those two periods - more so in 2020 than in 2021. We work in cash-based accounting like many other public bodies. Effectively, it is a case of "use it or lose it" in-year. We look at where there might be opportunity or demand in areas. The Senator referenced the solar PV scheme. That scheme requires a visit that takes half a day in and out of a home. People are much more amenable to that than the four weeks, let us say, of a contractor coming in and out of their home for retrofitting. We found other opportunities to spread our funding around in-year.
