How to Audit Your Energy Bills and Identify Hidden Overcharges

Utility expenses are a significant line item for property owners in New York City, but many don’t realize they may be overpaying due to billing errors or inefficient contracts. Slattery Energy, founded by Jim Slattery, brings over three decades of experience as an energy consultant to help building owners and managers detect and correct these issues.

As the official energy consultant for the New York Apartment Association (NYAA), the firm focuses on transparency, cost control, and compliance for the city’s real estate sector.

Why Energy Audits Matter for NYC Property Owners

Energy audits serve as a tool to uncover hidden charges in gas, electric, and oil bills. These overcharges often go unnoticed, especially in properties with high utility usage and complex billing structures.

Slattery Energy offers focused audits that help identify discrepancies, recover costs, and improve procurement terms. With its role in representing NYAA members, the firm emphasizes owner advocacy and accuracy in energy spending.

Common Utility Billing Errors and Overcharges

Several types of billing errors can affect a building’s utility costs. These include incorrect tariff applications, duplicate line items, misread meters, and wrongly assigned late fees. In many cases, these issues result in ongoing overpayments.

Slattery Energy’s team of energy brokers conducts detailed reviews of usage patterns, contract structures, and supplier terms to detect these problems. Their work is closely tied to NYC gas consulting, where improving energy supply contracts can have direct financial impacts.

The Energy Bill Audit Process Explained

A comprehensive energy audit involves several stages. First, the audit team collects 12 to 24 months of past utility bills. Then, a detailed analysis identifies inconsistencies and mischarges. Once errors are documented, the team contacts suppliers for corrections or refunds.

The final phase involves assessing long-term usage trends and identifying areas for contract or operational optimization. Drawing on more than 30 years of sector-specific knowledge, Slattery Energy offers a structured, data-backed process to secure sustainable savings.

Stay Compliant With New York Regulations and Local Laws

Energy bill audits also support regulatory compliance. In New York City, local laws like LL87 and LL97 require accurate reporting and performance benchmarks. Catching billing errors early can help avoid non-compliance risks.

In addition, Slattery Energy’s audits often identify opportunities for energy rebates, which further reduce costs while aligning with New York regulations. This makes audits a practical step toward both operational efficiency and legal accountability.
