Mercer County Executive Brian M. Hughes in 2017 consolidated the offices of Consumer Affairs / Weights & Measures in a continued effort by his Mercer County Administration to improve government efficiency.

While both offices provide consumer protection, Consumer Affairs deals with consumer complaints relating to home improvement contractors, used-car dealers and other business entities that may be in violation of N.J.S.A. 56:8-1 et seq. (The Consumer Fraud Act). All staff members are trained, have passed all courses required by the New Jersey Attorney General’s Office and are certified.

Consumer Affairs cannot:
• Act as a lawyer or handle a complaint when a lawyer is involved.
• Recommend a business, product or service.
• Investigate or resolve complaints from consumers against other consumers.
• Take action if a complaint has involved court action or a court decision.

Weights & Measures is responsible for inspecting and certifying all commercially used weighing and measuring devices in Mercer County (except the City of Trenton, which has its own Office of Weights & Measures). Weights & Measures annually inspects devices such as gas station meters, scales at delis and supermarkets, home heating oil meters and timing devices found at laundromats and on air and vacuum machines. Weights & Measures enforces N.J.S.A. 51:1-1 et seq. (Standards, Weights, Measures and Containers).
