One of the questions, which was also how can we be sure that we're not just simply paying above the odds in terms of our insulation and heat pump insulation projects—the fact that we are going in and we're making sure that our public houses are warm, safe, dry places for people to live. In terms of the procurement process, this was, of course, done through a competitive panel process. We are doing it at bulk, so, actually, we are able to get some of the economies of scale across this, because we're giving secure pipelines of work to providers. I know, visiting a number of our insulation providers around the country—I know, certainly, in Christchurch, Community Energy Action have been in the position, because of the Warmer Kiwi Homes programme of taking on apprentices in this area and training young people in this. So I think we're seeing long and good pipelines of work leading to benefits way beyond just us having warmer, drier homes, which, actually, I think is a pretty good benefit anyway.
