A map of business water suppliers in England and Scotland

Business water vs household water – what’s the difference?

Businesses can switch business water suppliers, unlike the household market, which cannot change their business water supplier.

Business water is the supply of water to your business. Businesses in England and Scotland are allowed to switch their supplier. As a business, you can compare and switch suppliers to ensure you’re getting the best water rates and service.

Household water is the water supply to homes or properties where the principal use is a household. In England and Scotland, households cannot switch their water supplier and have to stick to their local wholesaler for their water supply.

FAQ’s – Business water suppliers

Can I change business water supplier?

Since 2017 business and other non-household premises are free to change water suppliers. This guide provides a comprehensive list of English and Scottish water suppliers. Each of the water suppliers on this list holds a licence to supply water and wastewater services to British businesses.

Use our comparison service to switch business water suppliers.

How can I change business water supplier?

The onboarding process for each business water supplier is different. Where available, we have provided the relevant links to request a water quote from each supplier.

Alternatively, AquaSwitch can do the work on your behalf by collecting tailored quotes from across the market. AquaSwitch can quickly give you a view of available alternatives for your business.

If you decide to change supplier, AquaSwitch will arrange a hassle-free switch on your behalf. For more information, see our free business water comparison service.

How to find my business water supplier.

The easiest way to find your current business water supplier is to check who sends you business water bills.

If your business has recently moved into a new property or you’ve never received a bill, then AquaSwitch or any business water supplier on this list can help you find who your current supplier is.

All business water supply points are recorded on a centralised database that documents who supplies each business water meter at non-household addresses. AquaSwitch has access to this database and will help with such queries.

What do business water suppliers do?

The jargon in the water industry makes it challenging to understand what water suppliers actually do. Water suppliers, retailers, providers, these are all mean the same thing.

In short, water suppliers provide billing and customer services to businesses, organisations and other non-households. A water supplier will arrange regular meter readings to produce accurate water bills for your business.

Business water suppliers are not responsible for maintaining the water network; this is the role of the wholesaler. If any physical supply issues arise for your business, your water supplier will contact the wholesaler on your behalf to arrange for it to be fixed.

Can my small business change water supplier?

Yes, the suppliers in this guide have a licence from Ofwat or the Water Commission for Scotland to supply any non-household in Britain, both large and small.

The only requirement for a small business to be able to choose a business water supplier is to have been allocated a supply point ID (“SPID”).

All water bills your business receives will display your SPID.

Self-supply businesses

Deregulation of the English water market introduced the option to 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 adds some obligations such as paying for water two months in advance and regularly recording meter readings but saves the business from paying a supplier the retail fee.

Economically self-supply can make sense for larger firms. In March 2020, 12 companies held a self-supply licence, including John Lewis and Kelloggs.

Smaller business water suppliers

This guide has provided information on all major water suppliers based upon Ofwat’s latest state of the market publication.

We have excluded from this guide a handful of suppliers 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.

Who are the business water suppliers in Scotland?

As mentioned above, the following business water suppliers have a supply license to supply water in Scotland:

  • ADSM
  • Bluewater
  • Brightwater
  • Business Stream
  • Castle Water
  • Clear Business
  • Commercial Water Solutions
  • Everflow
  • Source4Business
  • Pinnacle Business Water
  • Pure Utilities
  • Smarta
  • SES Water
  • Water Plus
  • Water2Business​​
  • Wave

Do businesses pay water rates?

Businesses do pay water rates and have the option to choose who their business water supplier is, unlike households.

If you haven’t switched your commercial water supplier before, we suggest using our business water comparison tool to help you analyse the market and to easily see the different tariffs available to your business.

How to compare and switch business water suppliers

If you’ve never changed supplier before, you’ll probably find it’s a lot easier than you expect to switch water suppliers, just grab a recent water bill and enter your postcode and SPID in our form to compare business water suppliers.

Our free comparison service will collect tailored water quotes for your business from across the open water market.

If you decide that a different supplier can provide a better service and tariff to your business then AquaSwitch can handle your switch. It’s completely free.

And remember, switching supplier doesn’t involve any physical work at your property, or new pipework being installed – your water will be still be supplied through the existing pipes.

The difference is you will be billed by the new supplier benefiting from cheaper water rates and improved customer service.
