If you’re happy with a quote, we’ll help you switch business water suppliers with no interruption to your water supply, so it’s completely hassle-free.
What should you compare in business water quotes?
Business water bills are made up of several charges, and the amounts vary depending on where your property is, its size and how much water you use.
That makes it hard to tell whether you’re overpaying, so it pays to look at each charge when comparing water suppliers’ prices. Our business water rates calculator shows how these charges work together on your bill.
Here’s what to look out for in each quote:
Unit charges
This is the price you pay for each cubic metre of water your business uses. It’s often the biggest part of your bill, so even a small difference between quotes can add up over a year.
Standing charges
These are fixed charges you pay regardless of your usage, to keep your business water connection running for water and sewerage. They’re usually linked to the size of your water meter.
Wastewater charges
This is what you pay for the water that leaves your premises and goes into the sewer. Charges usually assume around 95% returns to the sewer, so if yours is lower, you may be able to claim a sewerage rebate.
Drainage charges
In certain regions, there are separate charges for the drainage of rainwater from your property and nearby roads. Your surface drainage charge is usually based on the size of your site.
Trade effluent
If your business discharges anything into the sewers other than standard wastewater, you’ll pay trade effluent charges. These are based on the volume and strength of what you discharge.
Contract terms
Check how long each contract runs, which charges are fixed and how often you’ll be billed. Suppliers compete on the retail part of your bill, so this is where the biggest differences between quotes tend to be.

What to consider when you compare business water
Price matters, but it isn’t the only thing that sets suppliers apart. Once you’ve found a competitive quote, it’s worth checking how each supplier will look after your business day to day:
Customer service
Some suppliers take customer experience more seriously than others. Checking Trustpilot scores gives you a quick feel for how each one handles queries and complaints.
Online accounts
Many suppliers offer online portals where you can view bills, submit a meter reading and manage all your sites in one place, saving your team time.
Payment options
Check whether each supplier bills in advance or in arrears, and which payment methods they accept, such as direct debit, so it fits how your business manages cash flow.
Smart meters
Some suppliers offer smart water meters that track usage daily, giving you more accurate bills and helping you to spot a commercial water leak quickly.
Water efficiency
Some suppliers offer support to help you reduce water consumption, from usage reports to on-site advice, lowering your bills over time.
Green tariffs
If your business has environmental targets, look for suppliers offering carbon neutral tariffs that offset the emissions linked to your water supply and wastewater treatment.

Business water comparison FAQs
Our business water experts answer the most common questions about comparing business water suppliers and prices.
Will business water prices keep increasing?
Yes, wholesale water charges are reviewed every April. Ofwat’s latest price review allows wholesale charges in England to rise by an average of 42% before inflation between 2025 and 2030, to fund investment in the water network.
The biggest jump came in April 2025, with further, mostly smaller, increases from April 2026. All business water suppliers pass through these underlying wholesale water costs to customers.
Can small businesses compare water rates?
Yes, any business can compare and switch water suppliers, as long as the property isn’t a home. Small businesses on default contracts often have the most to gain from comparing the market.
When should I compare business water suppliers?
You can compare your rates with the market at any time, but the best time is in the last three months of your current contract. In these last three months, we can arrange your switch to start on your contract end date to avoid paying unfavourable out-of-contract rates.
If you’ve never switched, you’re likely on a default tariff and so can compare and switch at any time.
Do I need a SPID number to compare?
No, but it helps. Your Supply Point ID (SPID) is a unique number on your water bill that lets our experts check your meter size, past water use and site area. If you can’t find it, we can usually find it using your business name and address.
Can large businesses compare water rates?
Yes, and businesses with large or complex water use often have the most to gain. Bills across multiple sites can include high usage charges, trade effluent and different regional rates, which makes it hard to spot where you’re overpaying.
Our experts can review your rates across your whole portfolio, prepare a clear comparison of your options and check past bills for errors through water bill validation. Enter your head office postcode above to get started.
How do green business water tariffs work?
Green tariffs offset the carbon emissions linked to your water supply. Pumping and treating water uses a lot of energy, and treating wastewater releases greenhouse gases, so the environmental impact of the water industry is significant.
Suppliers offering green tariffs typically balance these emissions by investing in projects such as tree planting or by buying carbon credits.
Can I compare business water suppliers anywhere in the UK?
No, it depends on where your business is based:
- England: All businesses can choose their water supplier.
- Scotland: Businesses have been able to choose their supplier since 2008, with Scottish Water providing the wholesale service.
- Wales: Only businesses using more than 50 million litres of water a year can switch, which usually means large industrial sites.
- Northern Ireland: Businesses can’t switch, as NI Water is the only supplier.
Can I compare water suppliers for my home?
No, households in the UK can’t currently switch water suppliers. Homes are supplied by the regional water company that runs the network in their area.
You can check who your water supplier is and see how business water rates compare with domestic rates.
Who can compare business water rates?

- Offices, shops and commercial premises
- Restaurants, pubs and cafés

- Charities and non-profits
- Churches and other places of worship
- Schools, nurseries and public buildings
