National Exemption Service has been providing Submetering and Utility Billing for nearly 50 years. NES will supply and install a meter in each unit. This ensures that each unit pays only for its actual usage using the same rates and tariffs as your municipality. The biggest upside to submetering is conservation of resources. Once a property is submetered, the usage is reduced by an average of 18%. NES services community’s nationwide, including new construction and existing properties – those with equipment in place and those requiring equipment.
