Well, about time, too, because the last time this Government brought forward proposals to strengthen part L building regulations, Plaid Cymru, my colleagues and I, argued fervently that the Government should be much more ambitious. Despite consulting on a 40 per cent or a 25 per cent strengthening of energy efficiency, your Government plumped for a measly 9 per cent increase. Now, we argued against, you voted us down. Three years later, we have a number of houses that have been built in the meantime that are actually locking in that energy inefficiency that you supported and which we opposed. Do you regret that?
