The Member makes an important point: it's important in all these schemes that efficiency is gained and value for money is achieved. Of course, it's not just the Welsh taxpayer who funds the Arbed scheme; a significant proportion of that money comes from the European regional development fund. So, I wonder what work is being done, in advance of Brexit, to ensure that energy efficiency schemes that look to make homes in Wales more efficient moving forward and help to deliver success for the climate change emergency, what work is being done to make sure that schemes like this do continue and we do continue to have sustainable homes in the future beyond Brexit.
