• ✓Welsh Water: if you do not have a water meter, you are charged a fixed cost each year based on your property, and unmeasured bills are sent once a year.
• ✓Welsh Water: the unmeasured bill is a rateable value charge, made up of a standing charge plus a charge per pound of rateable value; a uniform service charge for properties built between 1 April 1990 and 31 March 2000, based on the average rateable value in Wales; or an assessed measured charge if you applied for a meter and one could not be fitted.
• ✓Welsh Water: with a meter you pay a fixed service charge plus a charge for each cubic metre you use, and it bills every six months.
• ✓Ofwat: if you do not have a water meter, your bill is not based on how much water you use. It is usually a fixed charge plus a charge based on the rateable value of your home, a valuation last updated in 1990.
• ✓CCW: if your new home already has a water meter, you must pay metered charges based on your usage and you cannot switch to an unmetered bill. Take a reading as soon as you move in.
• ✓CCW: a water company can install a meter when you move in, but not if you have already received an unmetered bill for that property. It tells you when you report the move.

• ✓Welsh Water: it installs meters free of charge, and you can switch back to your unmeasured charge at any time up to two years from the date the meter was installed.
• ✓Welsh Water: the switch back is only for customers who moved from unmeasured to metered charges. If you move into a property that already has a meter, the option is not available and the meter cannot be removed.
• ✓Welsh Water: to apply, you need to be the registered bill payer, or a tenant who pays for water to a local council or housing association.
• ✓Welsh Water: it suggests a meter might save you money if you live alone or do not use much water, and its meter page estimates 2026/27 metered charges by household size.
• ✓Ofwat: household customers in England and Wales can choose to have a meter fitted in their homes free of charge. If a meter cannot be fitted, the company must offer an assessed charge instead.
• ✓Ofwat: in Wales, your water company should install the meter within three months of your request. If it does not, it should offer to adjust your bill to what you would have paid on a meter.
• ✓CCW: you can usually switch back to the unmetered charge within two years if you are unhappy with the change, except for customers in areas of England where compulsory metering is introduced. Where the company publishes its own rule, as above, that is the one to go by.
• ✓CCW: if you rent your home in Wales, your landlord can prevent a water meter being fitted if your rental agreement is for less than six months.

• ✓Welsh Water: its contact page routes you by topic, including account queries and moving, water meters, and help with your bill.
• ✓CCW: the homeowner is responsible for maintaining the water pipes on private property up to the boundary of the road. The water main, the connection up to your boundary, the outside stop tap and the meter are the company's.
• ✓Ofwat: companies are required by their licences to reimburse the cost of water lost through leakage by way of credits to your bill, a leakage allowance that can apply to water and wastewater charges. You can only claim once the leak has been repaired, and it can be refused if you did not arrange the repair within the company's timeframe.
• ✓CCW: complain to the company first and give it a chance to put things right. If it does not reply within 10 working days you may be entitled to a Guaranteed Standards Scheme payment. CCW can take the complaint on once you have a final response or have waited eight weeks, and its service is free.
