The Thames Water Metre Calculator helps you calculate your water usage by determining the difference between your current and previous water metre readings. This simple calculation provides an accurate measurement of your water consumption in cubic meters.
The calculator uses a simple formula:
Where:
Explanation: This straightforward calculation subtracts your previous reading from your current reading to determine exactly how much water you've used during the billing period.
Details: Regularly tracking your water usage helps you monitor consumption patterns, identify potential leaks early, manage your water bills more effectively, and contribute to water conservation efforts.
Tips: Enter both current and previous readings in cubic meters (m³). Ensure the current reading is equal to or greater than the previous reading. Readings should be taken from the same metre and use the same units of measurement.
Q1: How often should I read my water metre?
A: For accurate tracking, read your metre at regular intervals, typically monthly, to monitor your consumption patterns and detect any unusual changes.
Q2: What if my current reading is less than my previous reading?
A: This typically indicates an error in reading entry, metre malfunction, or that the metre has been reset/replaced. Double-check your readings and contact Thames Water if the issue persists.
Q3: Where can I find my water metre?
A: Water metres are usually located outside your property near the boundary, in a small chamber or box, or inside your home near the stop tap.
Q4: How do I convert my reading to cubic meters?
A: Most modern metres display readings in cubic meters (m³). If your metre uses different units, check with Thames Water for conversion factors.
Q5: What is considered average water usage?
A: Average household usage varies, but typically ranges between 100-150 liters per person per day, which translates to approximately 3-4.5 m³ per person per month.
