What’s the difference between domestic and business water supply?

3 June 2025

The main difference between domestic and business water supply in the UK lies in how the markets are regulated and billed. Domestic customers typically receive water services from their regional supplier and can’t switch providers, while most businesses in England have been able to choose their supplier since deregulation in 2017.


Business water is billed differently, too. While household bills are based on standard tariffs and property size, business water charges consider actual usage, wastewater output and site-specific requirements. This means businesses can benefit from tailored deals, but it also means charges may vary more depending on your operations.


There’s also a difference in customer service and contract terms. Business customers often have access to dedicated account managers and can negotiate bespoke agreements, whereas domestic supply is more uniform and regulated.


Ultimately, the business water market offers more flexibility but also requires more active management. That’s where Clear Utility Solutions can help. We’ll review your contract, usage and billing to ensure you’re getting the right deal.
