Mr. Graham Doyle:

Yes, it depends on if you are talking about the shallow or deep retrofit. Obviously the deep retrofit is more challenging, physically and financially. Some 75,000 social houses out of 140,000 have had a shallow retrofit, so that is just over 50%. A lot of the social housing stock is new build, which is built to BER rating 2. Offhand, I think that is another 25,000 houses. Quite a proportion of the stock has had some level of retrofit. The challenge is deep retrofits across 36,000 units over the coming years. We are trying to gear-up towards that. In the last year about 800 or 900 were done. There was a significant reluctance among people within the homes to get into that during Covid. That was not really the issue, which was more that of the restrictions. The question is ramping up that. It is a big challenge. Deputy Catherine Murphy mentioned the rising costs in that space earlier. We are focused on working with the local authorities to try and with some advice coming through the Housing Agency too on these issues.
