No, the pricing remains the same for all industries. However, some industries are more likely to have larger and more complicated water systems than others. For instance, a medical centre will typically have a staff room, staff toilets, service user toilets, wash hand basins in consulting rooms and a tank and cylinder. Whereas a commercial office might have a kitchenette, a male and female toilet and an electric water heater. So depending on the size of the water system itself will determine the time required to assess and maintain it.
