My hon. Friend makes a good point. I will come on to how mutuals would allow customers to have a lot more say over—indeed, they would give them ownership of—the water services on which we all depend.
Turning to one specific company, Thames Water was owned for 11 years by a complicated string of holding companies and offshore businesses, all ultimately owned by Macquarie bank, receiving returns of between 15.5% and 19%. Research by the Financial Times suggests that between 2006 and 2016, Macquarie and its fellow investors paid themselves £1.6 billion in dividends, while Thames Water was loaded with £10.6 billion of debt and ran up a pension deficit of some £260 million.
Dividend, debt and pension deficit were not the only things to increase under Macquarie’s control of Thames Water; customer bills and complaints also soared. The only thing that went down during this period was customer satisfaction, which is now ranked 22nd out of 23 in the Consumer Council for Water league table.
