About Wave
Wave is a joint venture between Anglian Water Group and Northumbrian Water Group. It brought together the business retail teams of Anglian Water and of Northumbrian Water and Essex & Suffolk Water.
The Competition and Markets Authority cleared the joint venture in August 2017, and Wave now serves business customers across England and Scotland.
Where Wave 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 Wave? Here's how we can help
At Black Sheep Utilities, we're an independent business energy and water broker, not part of Wave 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 Wave 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.

Words we use here
- LOA (Letter of Authority)
- A document you sign that lets us act for you, including talking to your current supplier and other suppliers and getting your meter information. Ours is a level 1 LOA: it lets us help with your contracts, bills and supplier queries, but not enter into a contract on your behalf. Only you can agree a contract.
