Estimate your household water and sewerage costs in the UK
The Water Bill Estimator (UK) is a simple and reliable tool designed to help households across the United Kingdom estimate their water and sewerage costs. By analysing factors such as household size, water usage, and metered or unmetered supply, this tool provides a clear indication of your likely water bill—helping you budget more effectively and identify opportunities to save water.
Whether you’re moving home, switching to a water meter, or reviewing your monthly expenses, this estimator gives you a practical snapshot of your expected water charges.
UK water bills typically include two main charges:
This covers the cost of clean water supplied to your property for drinking, cooking, washing, and cleaning.
This covers the removal and treatment of wastewater, including water from toilets, sinks, showers, and rainwater drainage (where applicable).
Charges vary depending on:
Your water company
Whether your home is metered or unmetered
Household size and water usage
Regional pricing differences
The estimator uses typical UK consumption data and pricing structures to calculate an estimated annual or monthly water bill.
You simply provide details such as:
Number of occupants
Property type
Metered or unmetered supply
Approximate water usage habits
Based on these inputs, the tool calculates:
Estimated water supply costs
Estimated sewerage charges
Approximate total water bill
If your property has a water meter, you pay for the exact amount of water you use. This is often cheaper for smaller households or low water users.
Unmetered bills are based on your property’s rateable value, not actual usage. This may suit larger households or properties without a meter.
The estimator helps you compare both options and understand which may be more cost-effective.
