I'm wondering whether to use a water meter. I live alone so there isn't a big usage of water in the house. Does anyone use one and has it saved them money?
It saved me a fortune when we swapped to a water meter. There was just the two of us in the house at that time and it cut my bill by three quarters. We still watered the garden with the hosepipe when necessary (we also have water butts for that) and wash the car, do all the usual things.
We continued to use the dishwasher and washing machine as normal.
Go for it! If you do find it is costing you more you can revert to the old payments if you do so within the first year.
A water meter is a benefit if few people live in the house. The fewer the residents, the bigger the benefits. A water authority usually charges for water in the assumption that four people live in the house. If a water meter is installed, the resident(s) pay for exactly what they use, and not for what the water authority assumes that they use. One resident can only gain from having a water meter fitted.
I live in a one bedroom flat (just me) I was paying £24 a month, had a meter fitted 6 months ago, I now pay £13. Shower every day, washing machine used on average three times a week.
