Is business water cheaper than domestic water?

Business water rates are generally cheaper per unit than domestic rates, but several factors influence this. Your industry, water usage, and the location of your business premises all play a role in determining your rates. Some businesses may also require different tariffs based on their specific needs.

While the total water bill for a business is usually higher than that of a household due to larger premises and higher usage, the unit cost is often lower. This is because businesses typically consume more water, allowing for more competitive pricing.

Thanks to deregulation, businesses have the option to switch their water contract, which can lead to further savings. However, water rates are regulated annually by Ofwat, making the market dynamic and requiring regular review to secure the best deals.

At Utility Bidder, our experts continually compare business water rates to ensure you’re getting the most competitive rates available, so you don’t have to worry about navigating this complex market alone.

How are commercial water rates calculated?

At face value, water flows out of our taps and down the drain, but there’s a lot more going on in the background to make up our business water rates. Unlike domestic water usage, businesses often have far greater and more varied requirements, meaning tariffs can sometimes be more complicated.

To help you understand your business water tariff and find the best deal, here are the main rates and charges that commercial water suppliers use to calculate your bills.

Potable water metered rates

This charge is based on the volume of clean water supplied to your premises. The more water you use, the higher your bill. Business water providers take regular meter readings to ensure accurate billing.

Potable water standing charge

Also known as the metering charge, this is a daily fixed fee applied to all businesses, regardless of water usage. It covers the maintenance of pumping systems and external pipes that supply water to your property.

Wastewater metered rates

This charge assumes that the clean water used on your premises will eventually enter the wastewater system. Meter readings help determine the amount of wastewater generated, which informs your wastewater charges.

Wastewater standing charge

Applied to maintain the sewage systems, this standing charge covers the infrastructure needed to carry wastewater away from your premises via sewerage pipes.

Sewerage charges

Business water rates also contain a fee to cover sewerage services. These charges include:

Foul sewage: The cost of removing and treating wastewater that comes from toilets, sinks, and other internal drains into the public sewer system. This is usually estimated at 95% of your water consumption.
Surface water drainage: This charge applies to rainwater that falls within your property boundary and enters the public sewer system.
Highway drainage: Covers the cost of removing water that drains from public roads and highways into the sewer system.

Business water comparison jargon buster

Confused trying to figure out the difference between default tariffs and wholesale rates? Don’t worry, we’ve got you covered. Our business water experts have busted some jargon to help you understand your contract and what it covers.

Water supplier

A licensed company responsible for providing water services to business customers. They source, treat, and deliver water to your premises and handle wastewater removal.

Business water rates

The total cost your business pays for water services, including both wholesale water rates and retail fees. These rates cover the delivery of potable water, wastewater management, and associated services.

Default water tariff

The out-of-contract rate applied if your business has never switched from its original water supplier. This tariff is usually higher than negotiated rates available in the open market.

Non-household property

A commercial or industrial property eligible to participate in the open water market, allowing businesses to switch water suppliers for better rates and services.

Retail fee

A charge from your water supplier that covers administrative services like meter readings, billing, and customer support. Retail fees are a component of your overall water bill.

Return to sewerage allowance

A calculation used to estimate the volume of water returned to the sewer system after use. This figure is typically based on the amount of potable water recorded by your meter and is essential for determining wastewater charges.

Smart meter

An advanced meter that automatically sends accurate water usage data to your supplier, eliminating the need for manual readings and helping to manage water consumption more efficiently.

Supply point ID (SPID)

A unique ten-digit identifier for your business’s water supply points. It is used within the water industry to manage and locate your water service details.

Water efficiency

The practice of reducing water usage and waste through measures like fixing leaks, installing smart meters, and adopting water-saving technologies. Improved water efficiency can lead to significant cost savings.

Wholesale water rates

The portion of your water bill that covers the cost of water supply and sewerage services provided by the wholesaler, which includes the maintenance of infrastructure and the treatment of water and wastewater.

Out-of-contract rates

Higher rates charged when a business’s water contract has expired, and no new agreement has been negotiated. These rates can significantly increase overall water costs.

Metering charge

A daily standing charge applied to cover the costs of maintaining and operating the water meter at your premises, regardless of actual water usage.

Standing charge

A fixed daily or monthly fee that covers the cost of maintaining the water supply infrastructure, including pipelines and meters, regardless of the amount of water used.

Potable water

This refers to water that is treated to be safe for drinking and other uses within your business. Potable water charges are typically based on metered usage.

Non-potable water

Water that is not treated to drinking water standards and is typically used for industrial processes, cooling, irrigation, or other non-consumable purposes.

Sewerage charges

Fees associated with the collection, treatment, and disposal of wastewater, including foul sewage, surface water drainage, and highway drainage. These charges are often based on the volume of water returned to the sewer system.

Leakage allowance

A concession provided by some water suppliers where a portion of your water bill is reduced if a leak is identified and repaired, based on the water lost due to the leak.

Open water market

The open market for business water services, allowing businesses to switch suppliers to find better rates and service terms. Applicable to non-household properties in deregulated regions.

Water audit

An assessment conducted to evaluate water usage, identify inefficiencies, and recommend ways to reduce consumption and costs. This can be particularly useful for businesses looking to improve water efficiency.

Contract end date

The date on which your current water supply contract expires. Knowing this date is crucial for planning any potential switch to a new supplier to avoid out-of-contract rates.

Metered vs unmetered water rates: What’s the difference?

When it comes to business water rates, companies typically have the option between metered and unmetered billing. Understanding the difference between these two can help your business manage its water costs more effectively.

Metered rates

Metered water rates are essentially usage-based billing. These types of contracts charge businesses based on the actual volume of water they consume, providing a direct correlation between usage and cost. Metered rates are typically best for businesses that want flexibility and potential savings with lower or variable water usage.

Here are some of the key features of metered water rates:

Usage-based billing: Charges are based on the actual amount of water your business consumes.
Water meter installation: A meter records the volume of water used on the premises.
Cost flexibility: The more water you use, the higher your bill; however, you only pay for what you consume.
Ideal for low/moderate usage: Suited for businesses that are mindful of water usage or have lower water needs.
Encourages water conservation: Potential for cost savings if water-saving measures are implemented.

Unmetered rates

Unmetered water rates offer a fixed-fee billing structure. These contracts charge businesses a consistent rate regardless of the amount of water consumed, allowing for predictable budgeting and cost stability. Unmetered rates are generally ideal for businesses with high or consistent water usage, as they provide a stable expense without the risk of fluctuating costs.

Here are some of the main features of unmetered rates:

Fixed fee billing: Charges are based on a fixed rate, regardless of the amount of water used.
Cost predictability: The fee remains constant, providing a stable monthly or yearly expense.
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 usage may end up paying more than necessary.
Potential advantages for high usage: Businesses with high or consistent water usage might benefit from unmetered rates as there’s no extra charge for increased consumption.

What’s the deal with water audits?

A water audit is a comprehensive review of your business’s water usage, billing history, and current rates, designed to uncover opportunities for cost savings. By analysing your water consumption patterns and identifying inefficiencies, a water audit can reveal ways to reduce your water bills and optimise your overall water management.

Conducting a water audit takes the hassle out of searching for the best rates. Instead of spending time and resources navigating the market, the audit does the legwork for you, pinpointing the most cost-effective solutions tailored to your business needs.

Through a straightforward three-step process, a water audit can offer actionable recommendations to help your business cut down on water expenses, ensuring you’re not overpaying and making the most of your resources.

What our expert says…

“2025 was a year of consolidation, not crisis. Wholesale electricity markets recovered from the extreme pricing shocks of 2022 and 2023 and continued the stabilisation pathway set during 2024. Prices remained sensitive to gas fundamentals, geopolitical risk, and weather volatility, but the market showed:

Stronger liquidity
Improved forward visibility
Calming price behaviour

Despite ongoing geopolitical headwinds, the blend of robust supply, easing trade tensions, and maturing hedging strategies has helped moderate UK forward electricity prices and provides a platform for opportunistic contracting in early 2026. However, low UK and EU gas storage into the start of 2026 and lower scheduled LNG shipments for the start of the year, leave the markets exposed to any sustained periods of cold weather and higher volumes of storage refilling through the summer months which has the ability to impact market pricing as seen in 2025.”

Frequently asked questions

Yes, businesses in England and Scotland can switch their water contract thanks to water deregulation. This allows you to shop around for better business water rates and service options, potentially saving money on your water bills.

No, your business water supply will not be cut off when switching. The physical supply of water remains uninterrupted, as the change only affects the company billing you for the service.

Water deregulation for businesses in England took effect in April 2017. Scotland’s water market was deregulated earlier, in 2008. Deregulation allows businesses to choose their water supplier, fostering competition and better service.

The main types of water meters include standard (manual read) meters, smart meters, and AMR (Automated Meter Reading) meters. Standard meters require manual readings, while smart and AMR meters automatically transmit usage data to your supplier, providing more accurate and timely billing.

Comparing business water suppliers can lead to significant savings, especially if you’re currently on a default or out-of-contract tariff. By comparing offers, you may find a deal with lower rates, better service, or added benefits tailored to your business needs.

Switching business water deals typically takes between four to six weeks after finalising your contract. This period allows for any necessary administrative processes and ensures a smooth transition without disrupting your water service.

Comparing business water prices can offer several benefits, including lower rates, improved customer service, and more flexible contract terms. It also allows you to choose a deal that better aligns with your business’s sustainability goals or specific needs.

Business water prices can increase due to factors such as inflation, rising wholesale costs, and changes in regulatory requirements. Regularly reviewing your contract and comparing suppliers can help mitigate the impact of price increases.

Business water rates vary depending on location, usage, and the supplier. Rates are typically composed of wholesale charges for water supply and wastewater treatment, along with retail fees for services like billing and customer support. To get accurate pricing, it’s best to compare quotes.

Business water rates can typically be fixed for 1 to 5 years, depending on the supplier and the terms of the contract. Fixing your rates can provide cost stability and protection against market fluctuations during the contract period.

Trade effluent water is any liquid waste discharged from industrial or commercial premises into the public sewer system, excluding domestic sewage. It often requires special treatment and must be managed according to specific regulations to prevent environmental harm.

For businesses with seasonal fluctuations in water usage, it’s important to choose a supplier that offers flexible tariffs or contracts that account for these variations. This can help you avoid paying for water you don’t use during off-peak times.

In the event of an on-site spillage, it’s crucial to act quickly to prevent environmental contamination. Contain the spill, notify your water supplier, and follow any specific protocols for cleanup. Depending on the substance, you may also need to inform the Environment Agency.

Ensure that your water meters are functioning correctly and consider upgrading to a smart meter for accurate, real-time readings. Regularly review your bills and consider a water audit to verify that you’re being charged correctly.

A Section 104 sewer is a drainage system constructed by a developer that is intended to be adopted by a water company. The agreement under Section 104 of the Water Industry Act 1991 outlines the terms under which the water company will take responsibility for the sewer’s maintenance after adoption.

A water efficiency plan outlines strategies to reduce water consumption, such as installing water-saving devices, fixing leaks, and optimising processes. Implementing such a plan can lead to significant cost savings and contribute to sustainability goals.

Sewerage prices are the fees charged for the collection, treatment, and disposal of wastewater. These charges typically include costs for foul sewage, surface water drainage, and highway drainage, and they vary based on location and supplier.

Wholesale charges cover the cost of water supply and wastewater services provided by the water company. Retail charges, on the other hand, are the fees for administrative services such as billing, customer service, and meter readings.

Yes, if you’ve been overcharged for your water services, you can usually claim back the overpaid amount. This often requires a thorough review of your past bills, and it’s advisable to consult with your supplier or a water audit specialist to assist with the process.

Higher water usage typically leads to lower unit costs, but it also means higher overall bills. Some businesses may benefit from bulk discounts, while others might be eligible for specific tariffs based on their consumption patterns.

A business water audit can be highly beneficial, as it helps identify inefficiencies in water usage, detects leaks, and ensures you’re being billed correctly. It can lead to significant cost savings and provide insights into how to reduce your water consumption.

If you suspect a leak, it’s important to contact your supplier immediately. Many suppliers offer a leakage allowance, which may reduce your bill based on the estimated amount of water lost due to the leak.

To reduce your business water bill, consider implementing water-saving technologies, fixing leaks promptly, conducting regular audits, and comparing deals to find the best rates. Educating employees about water conservation can also lead to lower consumption.
