Submetering, billing, and compliance that turns master-meter utility costs into recovered net operating income (NOI). NES is the in-house partner for multifamily owners and operators, from a single community to a national portfolio. One platform, one rep, every property, from the meter to your P&L.
National Exemption Service (NES) installs water, gas, and electric submeters in multifamily properties, reads them daily, pays the master utility bill, and bills each resident for what that unit used. Where meters cannot go in, NES allocates the bill by a disclosed formula instead. The company has done this in house since 1968, so owners deal with one vendor for equipment, billing, collections, and state compliance rather than three.
Properties that switch typically use 15 to 30 percent less water and recover the install cost in 12 to 18 months.
Submetering vendors are easy to find. A partner that runs every install, read, bill, collection, and state filing with its own people, on nonproprietary meters, and has done it since 1968, is not. That is NES.
Charges post directly to your PMS (property management system). Payments reconcile automatically. Usage shows up in the dashboards your team already checks every morning.
“Great Company..... including receiving a personal call from the Owner. This shows us that your company cares about its customers.”
National Exemption Service has been giving back to the community in a variety of ways since 1968.
An NES specialist reaches out within one business day to scope your property or portfolio and pull preliminary numbers. Your full recovery review and plan land within five business days.
National Exemption Service has been a pleasure to work with for the last year.
