Did you know your business doesn’t have to stick with the same water supplier?
Thanks to the Open Water Market, most businesses in England can now choose their own water retailer, just like they can switch gas or electricity providers. It’s one of the UK’s biggest steps toward utility deregulation—and it can lead to real savings and better service for your company.
In this guide, Scalex Technology explains what the Open Water Market is, how it works, and how your business can benefit.
What is the Open Water Market?
The Open Water Market is a deregulated system that allows non-household customers in England—like businesses, charities, and public sector organisations—to choose their own water and wastewater retailer.
It launched in April 2017 and is managed by MOSL (Market Operator Services Ltd). The idea is simple: introduce competition into the water industry to improve pricing, service, and innovation.
Who Can Participate?
The Open Water Market is open to:
- Businesses and commercial properties
- Schools and universities
- Charities and not-for-profits
- Local authorities and government buildings
To qualify, your site must be:
- Located in England (different rules apply in Scotland and Wales)
- Used for non-household purposes
How Does It Work?
Here’s how the Open Water Market operates:
- Wholesalers (like Thames Water or United Utilities) maintain the pipes, mains, and treatment facilities.
- Retailers (like Castle Water, Wave, Everflow) sell the service, bill customers, and offer customer support.
- You, the customer, choose your retailer based on price, service, and added benefits.
Benefits of Switching Water Suppliers
💷 Save Money
Retailers can offer competitive pricing, fixed contracts, or multi-site discounts to win your business.
🤝 Improved Service
Many retailers provide dedicated account managers, better customer support, and online billing portals.
🌱 Sustainability Options
Some suppliers offer water efficiency advice and smart metering, helping reduce consumption and lower your environmental impact.
Can I Switch My Business Water Supplier?
Yes—if your premises qualify, switching is usually:
- Free of charge
- Non-disruptive (no interruption to supply)
- Quick and easy (usually within 15–28 days)
You just need your SPID number (Supply Point ID, found on your water bill) and a recent usage summary.
