Guide to understanding business water comparison terminology
How are business water rates determined?
On the surface, water simply flows from our taps and down the drain, but business water rates involve much more behind the scenes. Unlike domestic water use, businesses often have higher and more diverse needs, resulting in more complex tariffs.
To help you navigate your business water tariff and secure the best deal, here are the key rates and charges commercial water suppliers use to calculate your bills:

Potable Water Metered Rates
This fee is determined by the volume of clean water delivered to your premises. The more water you consume, the higher the charge. Regular meter readings ensure accurate billing.
Wastewater Metered Rates
This charge assumes that most clean water used on-site will enter the wastewater system. Meter readings calculate the volume of wastewater produced, which determines your wastewater charges.


Potable Water Standing Charge
Also referred to as the metering charge, this is a fixed daily fee applied to all businesses, regardless of water usage. It covers the upkeep of pumping systems and external pipes that supply water to your property.
Wastewater Standing Charge
This fixed fee supports the maintenance of sewage systems, including the infrastructure required to transport wastewater from your premises through sewerage pipes.


Sewerage Charges
Business water bills also include fees for sewerage services, which typically consist of:
- Foul Sewage: Covers the removal and treatment of wastewater from toilets, sinks, and internal drains.
- Surface Water Drainage: A charge for managing rainwater within your property boundary.
- Highway Drainage: Covers the removal of water that drains from public roads and highways into the sewer system.
What is the difference between metered and unmetered water
Metered rates
Metered water rates are based on actual usage. These contracts charge businesses according to the volume of water they consume, linking usage directly to cost. Metered rates are generally suitable for businesses with lower or variable water consumption, offering flexibility and potential savings.
Key features of metered water rates include:
- Usage-based billing: Charges reflect the actual amount of water consumed by your business.
- Water meter installation: A meter tracks the volume of water used on the premises.
- Cost flexibility: Your bill increases with water use, but you only pay for what you consume.
- Ideal for low/moderate usage: Best for businesses that manage water consumption or have modest water needs.
- Encourages water conservation: Implementing water-saving measures can lead to potential cost savings.
At Mo Utilities, our specialists consistently evaluate business water rates to ensure you receive the most competitive pricing, saving you the hassle of navigating this complex market on your own.


Unmetered rates
Unmetered water rates follow a fixed-fee billing model. These contracts charge businesses a consistent rate regardless of their water consumption, offering predictable budgeting and cost stability. Unmetered rates are typically best for businesses with high or steady water usage, as they provide a stable expense without the risk of fluctuating costs.
Key features of unmetered rates include:
- Fixed fee billing: Charges are based on a fixed rate, regardless of water usage.
- Cost predictability: The fee remains the same, providing a stable monthly or annual cost.
- Property-based charges: Rates are often determined by property size, business type, and other factors.
- Less cost-effective for low usage: Businesses with low water consumption may pay more than necessary.
- Potential advantages for high usage: Businesses with consistent or high water usage may benefit, as there’s no additional charge for increased consumption.
What’s a water audit all about?
A water audit is a detailed assessment of your business’s water usage, billing history, and current rates, aimed at uncovering potential savings. By examining your consumption habits and identifying inefficiencies, it can highlight opportunities to lower your water bills and enhance water management.
Instead of spending time searching for better rates, a water audit simplifies the process by doing the research for you, offering customized, cost-effective solutions suited to your business needs.
With a straightforward three-step approach, a water audit provides practical suggestions that can help your business reduce water costs and ensure you’re using resources efficiently without overpaying
