You don’t get any choice about the water company you use - water is a natural monopoly. Yet in England we have sold off our vital national infrastructure to profit-making companies. (In Scotland and Northern Ireland water is already in public ownership and in Wales it’s not for profit.)
Publicly owned Scottish Water spends £72 more per household per year (35% more) on infrastructure than the privatised English water companies. If England had invested at this rate, an extra £28 billion would have been spent on tackling problems like leaks and sewage.
