About Business Stream
Business Stream is owned by Scottish Water and was its business retail arm. It became a separate company when Scotland opened its business water market in April 2008, the first competitive water retail market in the world.
It also supplies businesses in England, where it took on Southern Water's business customers ahead of the English market opening.
Where Business Stream supplies
- England: supplies business customers
- Scotland: supplies business customers
- Wales: only very large sites can switch in Wales
Whichever retailer you choose, your water and sewerage still come from your regional water company. In Wales, only sites using at least 50 megalitres a year can choose their retailer.

Thinking about Business Stream? Here's how we can help
At Black Sheep Utilities, we're an independent business energy and water broker, not part of Business Stream 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 Business Stream 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.
