Yu Water

Yu Water has gained a reputation for being one of the best business water suppliers for SMEs. It creates comprehensive packages for business owners who want to source electricity, gas, and water from one supplier.

Castle Water

Castle Water is an independent business water supplier that has amassed more than 350,000 customers.

Business Water Supplier FAQs

  • Will my provider offer a water audit?

    Some suppliers may offer a business water audit. A water audit can save you money on your water bill. There are many ways to increase water efficiency across both water and wastewater services. If a water audit is not offered, it is a good idea to ask your supplier about one. However, it is a good idea to walk around the business premises yourself with a water efficiency checklist. You will have to locate your water meter to conduct an accurate audit.

  • What is wastewater?

    Wastewater refers to any water that has been contaminated by human use. Any water that has been used in your business will likely make its way to the sewer where it is classified as wastewater.

  • How do I know who my current supplier is?

    You should be able to tell who your water retailer is by checking a recent water bill. It will likely be your local supplier if you have never gone through the process of switching supplier.
