The UK structures water provision as regional monopolies. This should be a hilarious joke but it's the reality. You can't change water company without living in a different region. There is no effective market competition for water provision in the UK. We already rely on price caps to keep this state of affairs in check.
Pretty much the only argument that almost stands up for them is that they're quite good at contributing to private pensions as a byproduct of being good stocks because people need water to not die. We gloss over where the rest of the money goes, possibly into PR management around frequent sewage dumping.
