Average water usage and cost
We’ve put together the information below to give you an idea of average water bill costs. This is based on the average use of water and wastewater (that’s all the water that goes your drains that we need to take away).
The figures are based on charges for the year April 2025 to March 2026. Please use these figures as a guide only – the amount of water you use will vary depending on your circumstances.
