Water competition

The business water market has changed

As of April 2017, businesses in England can now choose who they buy their water from.

Businesses in Scotland and high volume users in England were already able to buy their water from a number of licensed providers, but now an open market in England has given every business the freedom and flexibility to choose a water supplier that best suits their own needs.

This is great news, as it means prices will now be more competitive and there will be improved customer service.  In addition, businesses will have a choice of product options meaning your business can get the right products and services to suit your needs.

Understanding the new water market

What lies at the heart of the new regulations is the splitting of wholesale and retail water services. And if you’re wondering what the difference is, wholesale services cover the delivery of your water and the management of the infrastructure such as the pipe network and treatment plants. It also includes the removal and handling of wastewater. The changes in regulation allows the wholesaler to set the tariffs for these services.

Meanwhile the retail side relates to all the customer-facing activities including billing, meter readings, call centre support and water-efficiency advice. And these are the areas which benefit customers most in terms of competition.
