We discovered a water meter had been fitted to our house some years ago, turned out it was fitted to the wrong house. Anyway we stayed on the old water rates, but I monitored our usage, after two years I decided we would be better off on the meter, and because it wasn't reading zero when we switched they back dated the bills to when it was fitted, we got about £350 back for those two years
7LM, don't you think he's saving more than enough to cover the remote possibility of increased charges due to times of crises?
