The short answer
If you have more bedrooms than people in the house, a meter is usually cheaper. In England and Wales you can generally ask for one to be fitted free and switch back within a set period if it costs more.
- Compare the rateable value charge with your likely metered use. Your supplier's calculator will estimate it.
- The usual rule of thumb: more bedrooms than occupants means a meter is likely cheaper.
- Ask for a meter. In England and Wales it is normally fitted free on request.
- There is usually a trial period during which you can go back if it turns out more expensive.
- Check for a social tariff or a leak allowance if you are on a low income or have had a leak.
What will ruin it
Scotland does not have household water meters in the same way, and water is charged through council tax there, so this does not apply.
Why it works
Unmetered bills are based on the property's 1973 rateable value, which has nothing to do with how many people live there now. That mismatch is where the money is.
