Quick answer: Metered water bills charge for actual usage plus fixed standing charge — unmetered rateable value bills suit low-usage households in large properties.
Water companies in England and Wales must offer free meter installation on request. Switching back to unmetered billing is usually restricted within two years of having a meter fitted. This guide compares costs and helps you decide whether a meter suits your household.

Who saves on meters
Small households in large homes often cut bills significantly on a meter. A couple in a four-bedroom house with low water use typically pays less than the unmetered rateable value charge.
Large families with high usage may pay more on a meter than on unmetered charges. Use your water company's online calculator before switching to estimate the difference.
Installation
Apply to your water company for a free internal or external meter. Internal installation needs plumber access, while external meters are fitted outside the property boundary.
Shared supply flats can be difficult to meter individually. Check your water company's policy for converted houses and flats before you apply.
Scotland and Northern Ireland
Scottish Water charges work differently from England and Wales, with most domestic customers on unmetered charges linked partly to council tax band. Metering is less common in Scotland than in England and Wales.
Northern Ireland Water has its own metering policy. Check with the local provider for current rules on meter installation and charges in your area.
Common questions
Can landlord refuse meter?
Tenants can request a meter from the water company, though landlord consent may be needed for physical alterations. Water companies generally support tenant rights to choose metered billing.
Does gardening increase bills?
Hose and sprinkler use on a meter adds directly to your bill. Water butts and rainwater harvesting reduce metered consumption for garden watering.
What is assessed charge?
Some areas without individual meters use an assessed charge based on property type. This sits between rateable value billing and full metered charging.
