Watch out. The water boards want everybody to be on metered supply. They know that one incentive to go over to meters is the possibility of lower bills, which is why metered suppies are mostly cheaper ( for now) than unmetered. When 90 percent of customers ( or thereabouts) are on meters, they will force the remainder to go over by insisting on fitting meters when houses change hands. Or they will just do it anyway. However, when everyone is on meters, the income of the water boards will drop, possibly by almost half. They will then double their prices, which is what they have wanted all along. And then we shall all be totally at the mercy of the companies - which, remember, are profit-making companies. And, if I remember rightly, not all of them are UK companies.
