How does water billing work with and without a water meter?
Water bills in the UK are calculated differently depending on whether your property has a water meter. If you have a meter, your bill reflects the amount of water you actually use. Without a meter, your bill is based on a fixed charge, calculated using your property’s rateable value. This article explains how both systems work, including how sewerage charges are applied.
Understanding water billing: metered vs. non-metered properties
Water companies bill customers in one of two ways, depending on whether a water meter is installed at the property.
1. Water bills with a meter
If you have a water meter, you’re charged based on the amount of water you use, measured in cubic metres (m³).
- How it works:
- Your meter records how much water you use, and this data is used to calculate your bill.
- You’ll also pay a standing charge, which covers the cost of maintaining the water supply and sewerage system.
👉 Tip: To reduce your bill, try using water-efficient devices or lowering water consumption when possible.
2. Water bills without a meter
If your property does not have a water meter, your bill is based on a fixed charge determined by your property’s rateable value (RV).
- What is rateable value?
- It’s an assessment of your property’s annual rental value, set by local authorities before 1990.
- Even though rateable values are no longer updated, they’re still used to calculate water charges for non-metered properties.
👉 Tip: If your water usage is low, you might benefit from switching to a water meter, which could reduce your bills.
3. Sewerage charges
Sewerage charges are typically included in your water bill and are calculated similarly to your water usage:
- Metered properties: Sewerage charges are billed based on the amount of water used.
- Non-metered properties: Sewerage is charged as part of the fixed amount based on the rateable value.
💡 Did you know? Most of the time, the same company provides both water and sewerage services, which is why they appear together on your bill.
How to check or switch billing methods
- Check your current billing: Your bill should clearly state whether you’re on a metered or non-metered tariff.
- Request a meter: If you don’t have a meter and think it might save you money, you can ask your water company to install one.
- Consider a meter trial: Many companies offer a trial period where you can switch back to your old system if you’re not happy with the metered charges.
Understanding how water billing works helps you make informed choices about your usage and costs.
