Well, Janet, you won't be at all surprised to find that I don't share your analysis at all. You are obviously aware that the Nest scheme is not my portfolio; it is actually in my colleague Lesley Griffiths's portfolio. But, since 2011, more than 61,400 households in Wales have benefited from our Warm Homes programme, which supports people living on lower incomes to improve their home energy efficiency and save money. Between April 2017 and March 2021, we will have invested £104 million in the Warm Homes programme to improve up to another 25,000 homes.

We've also recently launched, through my portfolio, our optimised retrofit programme, which will support the retrofitting of 1,000 existing social homes this financial year. That's not very many, but it's the format of it that matters. The reason that we are doing that is because we disagree with the UK Government around the way that they've done the green homes initiative because one size simply does not fit all. It's quite obvious that the way to retrofit a Victorian stone terrace in the Rhondda is not the way that you would retrofit a 1970s cavity wall-built house in my constituency, for example. So, what we've done with our optimised retrofit programme is we are supporting social landlords who have every single type of house in Wales in their portfolio to come forward with a variety of technologies and schemes that will raise those houses from the Welsh housing quality standard that have already achieved C up to A. We will be able to see what works, and then we will be able to roll those programmes out so that what works for each house is available, rather than just a blanket one-size-fits-all programme that, frankly, will not work.
