What Is Included In A Business Water Bill?
Here are some of the things you may find on your business water bill:
- SPID (Supply Point ID) - a ten-digit code used by water suppliers to identify your business’s water consumption. You will likely have 2 SPID numbers as one is for freshwater supply and the other is for wastewater removal.
- Charges for freshwater supply and wastewater removal - freshwater charges include a fixed charge for meter maintenance and a volumetric consumption charge. Wastewater charges include a fixed charge for pipe maintenance with a return to sewerage charge.
- VAT is only charged when involved in chemicals, construction, engineering, manufacturing, mining, textiles and utilities.
When using a third-party intermediary (TPI) or broker, such as Power Compare, you don’t need to worry about anything. Simply enjoy seamlessly switching to your chosen business water supplier.
How Can I Find the Best Business Water Rates?
The easiest way to find the best business water rates is to compare the latest prices. With Power Compare, you can quickly find competitive business water rates from trusted suppliers.
All you need is a few details to get started. For the most accurate quotes it’s recommended that you provide:
- Your business name & address
- Your SPID number (Supply Point Identification Number)
- Your contact details
Your SPID number can usually be found on your business water bills. You’re then ready to compare business water prices and start your switch to a new deal.
Understanding Business Water Suppliers & the Water Market
The good news for businesses is that you are no longer tied to your regional water provider. If you operate in England and/or Scotland, you’re free to change water supplier.
Comparing business water suppliers is a little different to comparing business electricity or business gas.
When you switch, part of your service will still be provided by your regional water wholesaler. You can then switch to a ‘retail provider’ of your choice to manage your billing and all customer facing services.
If you’re yet to compare water suppliers, you will be with the default supplier based on your region.
Who Are the Most Trusted Business Water Retailers?
When choosing the best water retailer for your business, there are considerations beyond price competitiveness. One of the biggest factors is customer service. The below table shows the Trustpilot ratings for the UK’s default water retailers.

What Is A Water Retailer And How Are They Different From Wholesalers?
Water wholesalers own and operate the network of pipes for specific regions. They act as wholesalers who sell the water supply to retailers. Water retailers package up and deliver customer service to businesses in the UK.
Businesses will interact exclusively with their water retailer, whereas in the domestic water market, consumers interact with the wholesaler. In the domestic water market, there is no switching of water suppliers.
How Do I Switch Water Suppliers for the First Time?
Many businesses are still yet to switch water suppliers. This can result in playing more expensive out-of-contract rates with a default water retailer.
The good news is that comparing water suppliers is just as simple whether you’re switching for the first time or you’ve switched before.
When you compare business water prices, you can find the best deal available for your needs and fix your retail prices for up to 3 years.
If you have any questions about the process of switching, our expert team will be on hand to help.

-
Can I Switch Water Suppliers If I’m Still in Contract?

-
What’s SPID?
Business water suppliers use the SPID (Supply Point ID) to work out the supply to your business premises. It’s a 10-digit code followed by a letter and you’ll usually have one for your freshwater supply and another for your sewerage connection.
-
Do I Need My SPID When Comparing Water Rates?

-
Which Water Company Supplies My Area?
You can find out who supplies your water by looking at a recent bill. If you cannot find one, you can search who your local supplier is through Water UK.

How Do Unmetered Charges Work?
Some older buildings will not have a commercial water meter installed. In this case, your bill is not based on how much water you use. Typically your supplier will have a fixed charge for the business covering customer service and billing costs, with an additional charge based on the rateable value of the building.
A rateable value is a complex calculation suppliers use to understand how much to charge you.
-
What Is A Default Water Tariff?
This is a default level of service and is commonly known as the industries Default Standard Tariff. This is the maximum a provider can charge its customers for water and waste services.
-
