Business Water: Yes, You Can Switch Retailer

The business water market opened in England years ago and remains one of the least-shopped overheads.

How the market works

In England, businesses can choose their water retailer while the wholesaler continues to supply and maintain the network. Switching changes your billing, service and pricing — not the water itself.

Where the savings come from

Retailer margin is only part of the picture.

  • Consolidated billing across multiple sites
  • Correcting inaccurate meter records and estimated reads
  • Surface water drainage rebates where rainwater does not enter the sewer
  • Leak detection on the private supply pipe

Check drainage charges specifically

Surface water drainage is charged on assumed site area. Businesses whose premises drain to a soakaway or watercourse can often claim a rebate, sometimes backdated.
