Disclaimer

Most companies have their own water meter calculators which are based on regional water usage and may give you a more accurate estimated bill depending on your water use. We would therefore recommend checking with your water company before finally requesting a water meter to be fitted. If you choose to have a water meter, water companies install meters for free and generally customers can switch back to the unmetered charge any time within 12 months if they are unhappy with the change (not applicable to customers of Affinity Water Southeast, South East Water or Southern Water). If a meter cannot be fitted companies can offer an alternative unmeasured tariff which may be lower than the current bill.
