From Black Sheep Utilities

Thinking about SES Business Water? Here's how we can help

At Black Sheep Utilities, we're an independent business energy and water broker, not part of SES Business Water or any other retailer. Your regional water company looks after the pipes and the water itself. Your retailer handles your bills, meter reads and customer service, and that's the part you can switch.

  • Compare suitable retailers: when your contract is up, we compare SES Business Water with the retailers that cover your area and present the options that best suit your business.
  • Handle the switch: we do the leg work from start to finish, so your water keeps flowing and you don't have to chase anyone.
  • Check your bills: our team looks for errors and estimated reads, and we'll take it up with your retailer for you if something's wrong.

You don't have to do it alone. Find out more about our business water service, or give us a call.
