Here’s where the biggest business water suppliers are based:
Here’s our map of the different business water suppliers in the UK.
It is important to remember that business water suppliers have a licence to provide water services anywhere in the country. That’s why you can use our business water comparison service to compare commercial water suppliers from across the market.
If you have a property in Wales, it’s a bit more complicated; only industrial water users can use a business water supplier.
In terms of the number of properties they supply, the biggest business water suppliers are as follows.
The above rankings were extracted from the MOSL Supply Points Dashboard in October 2024.
This guide has provided information on all major water suppliers based on Ofwat’s latest state of the market publication.
We have excluded a handful of suppliers from this guide that make up less than 0.1% of the market. For a full table of business water suppliers, please refer to Ofwat’s latest state of the market publication.
The newest business water supplier is One Business Water, which Ofwat granted an English supply license in April 2024.
One Business Water is part of the Net Zero Planet Group, which is committed to the sustainable use of the world’s natural resources.
Intelligent Business Water is the newest supplier in the Scottish water market, having been granted a licence in January 2022.
The Scottish business water market was deregulated in 2008 to allow companies to benefit from greater choice, more services and competition among Scottish business water suppliers.
On 1 April 2008, the water supply to all commercial properties in Scotland transferred to Business Stream, the default business water supplier in Scotland.
There are currently 17 Scottish business water suppliers that compete to offer the best service at the cheapest prices.
In Scotland, business water suppliers purchase water and sewerage services from Scottish Water, which operates the water infrastructure. The following water suppliers currently have a licence to supply business water in Scotland:
Scottish business water suppliers are regulated by the Water Industry Commission for Scotland.
Deregulation of the English water market introduced the option of self-supply. Large businesses can apply from Ofwat for a licence to purchase water directly from wholesalers and take on the supplier’s role for themselves.
The self-supply regime means that a company with a licence has similar obligations to the business water suppliers. The self-supply business needs to pay for water two months in advance from the wholesaler and is responsible for recording meter readings at all sites.
The difference between a commercial water supplier and a self-supplier is that the licence restricts the company to only supplying water to properties they own or rent.
Economically self-supply only makes sense for large firms with properties across England and Scotland. In October 2024, the following companies held self-supply licences:
Yes, if you haven’t agreed to a contract with your current business water supplier, it is possible to negotiate a better rate.
Around 80% of companies in England haven’t contracted with their business water supplier and instead pay default business water rates. Default business water rates are needlessly expensive and can be renegotiated for cheaper fixed rates. Here’s how:
With AquaSwitch’s business water comparison service, you can compare your current rates to fixed-term quotes and see how much you can save.
Here’s a list of the business water suppliers that have ceased trading in the last three years:
Poor-performing business water suppliers going bust is a natural part of a competitive business water market.
However, water supplies are essential services so the regulator, Ofwat, ensures that when a supplier goes bust, there is a new business water supplier of last resort that will receive all the customers of the failed supplier.
To learn more about the process, refer to our complete guide to business water suppliers going bust.
If you are having a problem with a business water supplier, you should first contact the customer services team of your supplier. The customer services team should be able to resolve any issues that you are experiencing.
If explaining the issue over the phone doesn’t work, commercial water suppliers must have a formal complaints procedure to escalate matters. The complaints procedures of water suppliers are usually published on their website.
A formal complaint will result in a final decision letter issued by your supplier. If you remain unsatisfied with the response of your supplier, then you can request that your complaint be reviewed by the following:
Scottish customers:
Scottish Public Services Ombudsman

English customers:
Consumer council for water

All properties in Britain are connected to the water networks operated by local water companies, which are responsible for maintaining the pipes servicing households and businesses in their areas.
Despite using the same infrastructure, there is a big difference in business and domestic water supplies:
Businesses in England and Scotland can compare the different water suppliers and choose one that offers the cheapest water rates and the best service. Compare business water supplier rates today.
In 2023, we compared household versus default business water rates. Our study revealed that in 2023, domestic water rates were, on average, 18% cheaper than the rates paid by most small companies.
Over the past two years, there’s been growing outrage over the frequency that water companies dump sewage into rivers and onto beaches. This has culminated in serious doubts over the future viability of Thames Water, the UK’s biggest water company.
It’s, therefore, entirely understandable that people are concerned about the environmental impact of their business water supplier.
However, business water suppliers do not operate the water infrastructure that delivers water or removes sewage to your business. Instead, this is the role of your regional water wholesaler.
Here’s Water UK’s handy postcode tool to find out who is your regional water wholesaler.
To help raise awareness of the environmental consequences of the mains water supply, we’ve prepared a detailed guide to the environmental impact of the water industry.
Here are the top questions asked surrounding commercial water suppliers.
There are 17 business water suppliers in Scotland to choose from; see our list above.
The Scottish commercial water market was the first to deregulate in the UK, so the savings available from switching water suppliers away from the default tariff provider are significant.
The market operator MOSL publishes an annual trading party performance report; however, this focuses on more operational aspects of execution rather than customer-specific performance.
For this, we highly recommend undertaking your own due diligence. When reviewing water suppliers, it’s best to understand your needs and wants for a new commercial water supplier.
For example, are you just looking for a cheap supply? Or are you looking for improved customer service?
Once you understand what you want, it’s time to review the current and previous customers’ insights. We recommend that you go to each of the suppliers’ Trustpilot to get an accurate overview of the supplier.
You can view a list of trusted business water suppliers on our breakdown or verify them directly with Ofwat.
It entirely depends on what you are looking for from your next business water supplier. Is it price? Is it customer service? Is it multi-property billing services?
There are plenty of reasons why you wish to switch business water suppliers but to find the right option for your business, you must understand what you are looking for from a supplier.
Here are the most common reasons to switch business water suppliers:
It’s best to review each business water supplier and their additional services. You can grab that information in our ultimate guide to business water suppliers above.
Yes, you can change business water supplier. Since deregulation, businesses in England and Scotland have been able to change their business water supplier. Deregulation happened:
Deregulation split the water industry into water wholesalers and commercial water suppliers.
Water wholesalers are responsible for supplying clean water to all properties in your local area. When there is a problem with your water supply, water meter, or a leak in the pipe to your property, your wholesaler will fix the problem.
Since wholesalers are responsible for the water infrastructure in a particular region, it is impossible to switch wholesalers.
Business water suppliers purchase water directly from the wholesaler in bulk and then sell it to individual commercial users anywhere in the country.
For more information on changing commercial water suppliers, check out our complete guide on how to switch business water suppliers.
Yes. Scottish companies pay their chosen business water supplier for the following:
To learn more, check our handy business water rates calculator.
This can often be a point of confusion. On deregulation in 2017, some traditional water suppliers split into two similarly branded suppliers – a business water supplier and a household water supplier and wholesaler business.
A good example of this is in the Surrey region. The regional wholesaler, SES Water, supplies households, while SES Business Water supplies commercial properties.
SES Water is the company that owns and operates the local water network. SES Water is also the supplier to all homes in the region, providing invoicing and customer services.
SES Business Water is a licenced business water supplier that purchases water wholesale from SES water (and other regional wholesalers) and provides retail services to companies and other non-households.

The jargon in the water industry makes it challenging to understand what water suppliers actually do. Business water suppliers, retailers, and providers all mean the same thing.
The primary responsibilities of business water suppliers are:
Business water suppliers are not responsible for maintaining and operating the water network. The British water network is operated by regional wholesalers who fix any issues that might arise with your supply.
If there is an interruption to your water supply, your commercial water supplier will contact your wholesaler to resolve the problem.
Check out our complete guide to British water infrastructure for more information on the role of wholesalers.
The easiest way to find your current business water supplier is to look at a recent business water bill. Your supplier is the company charging for your water and wastewater services.
If your business has never received an invoice for your water supply or you’ve recently moved into a property, we offer a free service to determine who your water supplier is. Our in-house water experts can quickly check your property address details, and we’ll let you know your current business water supplier.
