Can a water meter save you money?

Try our water meter calculator to see potential savings if you switched to a water meter. If your water company can’t install a meter, they may offer an assessed charge. Even if you’re renting, you can have a meter installed as long as your lease is at least six months long. For more information, watch our video on everything you need to know about water meters (video).

    Surface water drainage occurs when rainwater falls on a property and drains away. Your sewerage company is responsible for removing and processing this rainwater and charge for this service. If rainwater does not drain from your property into a public sewer, because you have a soakaway or similar, you may already receive or be entitled to a surface water drainage rebate.

These figures are only estimates to give you a rough idea of your bill if you switch to a water meter. They may vary based on your appliances and how you use water, so don’t challenge your water company’s charges. Instead, check with your company to see if they have their own water meter calculator.

If you choose to get a water meter, it’s usually free and you can switch back to the unmetered charge within 24 months if you’re unhappy (except for customers of in areas of England where compulsory metering is being introduced). If you can’t have a water meter, the company may offer a cheaper alternative.
