Utility submetering puts a meter on each unit that measures and bills its water/sewer, gas, and electric use. The technology has been around since the early 1920s. NES installs the meters, reads them, pays the master-meter bill, and bills your residents, all in-house and with bilingual support.
When residents pay for what they actually use, they cut back. Most properties see 15 to 30 percent lower water use. Daily reads also catch leaks early, and common-area water stops getting spread across everyone's rent. Payback usually lands within 12 to 18 months.
Yes, with permission. Submetering of gas and electric in apartment houses is governed by Maryland Public Utilities Article 7-303, and permission must be obtained from the Maryland Public Service Commission before billing residents. Owners pass through only the charges the utility imposes, allocated by actual usage. For gas and electric, state law allows a billing or administrative charge of at most $1 per unit per month (7-303); NES adds no fee of its own. Gas RUBS allocation is not allowed except in buildings constructed before 1978, and then only with PSC permission. Since October 1, 2026, water submetering follows Environment Article 9-1115: residents pay only for their actual usage at the provider's charges, nothing for common areas, and at most $1 per unit per month in fees. Ratio billing for water still requires written disclosures, and some counties add their own rules. Owners must keep records residents can inspect. NES tracks every requirement so your property stays compliant.
