Local Government Finance Bill

I accept that revaluation too often can cause a problem, but does the Minister agree that the valuation process has not been changed for many years and the longer the period without a revaluation, the more likely it is that no Government will do it because it will make such a difference and there will be winners and losers? There has to be some sort of judgment between how long is too short and how long is too long for a review, and is not 10 years too long?
