Should you get a water meter?
A rough check only. Then use your water company’s numbers.
One or two people: it is worth running the official calculator. This page does not know your water company’s rates.
CCW says companies fit meters for free, and you can return to the unmetered charge within two years if you are unhappy, except where compulsory metering is being introduced in England. If a meter will not fit, ask about an assessed charge. CCW’s guide and calculator.
