Thames Water calculates its commercial water tariffs using three main components. For businesses with a meter, metered charges are based on actual water consumption, so you only pay for what you use. Properties without a meter are charged unmetered rates, calculated from the building’s rateable value, providing a standard method for business water pricing.
All businesses also pay for surface water drainage, which covers the collection and treatment of rainwater from roofs, car parks, and paved areas. Understanding these charges helps you compare suppliers and identify opportunities to reduce your commercial water bills.
