Business Water Rates

It is important to understand how much your bills should cost, to ensure that you aren’t needlessly overpaying. While there are a lot of factors that constitute business water rates, and every business will have unique factors that make their consumption different from even very similar businesses.

Property type, location, industry and general consumption can all have significant impact on billing, however at Castle Water, we take all of those factors into account, to not only give you competitive billing, but also valuable insight.

Every year, we put out schemes of charges, which takes into account pipe sizes, metering, property type and location to outline how much your bill should cost you.

Here’s an Example

This is what a bill from Castle Water might look like. A you can see, there are both fixed and volumetric charges which are added together to determine you’re monthly business water rates.

Volumetric business water rates

For sites equipped with a water meter, in addition to a fixed fee depending on the size of your water meter, volumetric charges are calculated as follows:

Water Use (m3) x Cost of Water (£/m3)

Water use is calculated by reading your water meter, while the cost of water is set by your water retailer such as Castle Water, and can vary depending on your overall consumption.

For sites without a water meter, all water costs are included in a fixed fee which is based on the rateable value of the site. 

Average Wastewater Bills

Like your water consumption, your wastewater billing will depend on a multitude of factors.

For sites equipped with a water meter, in addition to a fixed fee depending on the water meter size, wastewater volumetric costs are typically calculated as a percentage of total water user as follows:

Water Use (m3) x Return to Sewer Allowance(%) x Cost of Wastewater (£/m3)

The “Return to Sewer Allowance” is included because wastewater flows to drain under gravity instead of as a pressurised flow like water supply and it is not typically directly metered. The allowance is then used to account for mains water used but not discharged to sewer, in, for example:

  • Irrigation
  • Drinking water
  • Water used to make products for sale
