A useful New Hampshire utility audit identifies the disputed line item, the billing dates, and the contract or tariff provision that should apply. We compare the calculation with those records and distinguish a possible error from a supported recovery claim. A recent statement can help identify questions. A full historical review needs the records for the affected periods, with corrected bills and credits kept alongside the originals. ![Illustrative commercial utility statement, calculator and laptop for a billing review](https://rebateenergy.com/wp-content/uploads/2026/10/utility-bill-review- editorial.jpg) AI-generated editorial illustration.

No. Even when the same utility brand appears, electricity supply and natural gas transportation have different terms and records. We define each service separately. Can you review past utility overpayments? Our agreed historical review can cover up to 36 months of available records. A recoverable period depends on the account, applicable rules, contract, deadlines, and evidence. One questionable charge is not automatically a three-year refund. What happens after I upload a bill? The upload provides an AI-assisted preliminary screening for our team. People review the findings and follow up about records and scope. Recovery work requires a signed agreement and letter of authorization. This page describes Rebate Energy’s audit service for qualifying commercial accounts.
