Council Tax Valuation Bands Bill [HL]

My noble friend raises a very important point. He says there will not be a lot of complications. Is he not saying that, once his new post-2000 system comes in, each time the house is sold thereafter there will not be an alteration? That seemed to be the implication of what he said. If this system is to have the logic that I think it might well have, clearly at each point of sale—not, as he said, interestingly, of inheritance or gift—the system must, surely, generate a new council tax, whereas he seemed to be saying the opposite.
