CTCommercial utility bill auditing in Connecticut
Connecticut businesses can have a separate energy supplier while continuing to receive delivery service from the local utility. The review needs to identify both companies and the exact service being billed.
Connecticut electricity utilities and billing review
Eversource and United Illuminating are the electric delivery utilities highlighted in our Connecticut guide. A supplier price should be checked against the supply agreement, while delivery charges belong to the applicable utility tariff. An offer for one delivery territory is not automatically the correct comparison for the other.

Connecticut natural gas utilities and billing review
Connecticut Natural Gas, Southern Connecticut Gas, and Eversource / Yankee Gas have distinct gas tariffs and account records. For a transportation account, we follow the purchased gas and the utility delivery calculation separately. Eversource electricity and Eversource / Yankee Gas records should not be treated as the same service.
Commercial transportation programs; the utility still delivers the gas.
Follow the charge back to the record.
A useful Connecticut 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.
Records to prepare for your Connecticut bill review
- A recent complete utility statement, including every page
- The service address and state for each account
- Any separate energy supplier invoices
- Supplier agreements and renewal notices
- Historical statements, payments, credits, and rebills
- Meter or interval data when relevant to the questioned charge
Keep multiple locations organized by account. We define the full scope with you before recovery work begins. See our process and standard recovery pricing for the engagement steps.
Connecticut utility audit questions
My electricity and gas both mention Eversource. Are they one review?
They can be included in an agreed engagement, but each service needs its own bills, meter records, and applicable rates. The company name alone does not establish the calculation.
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.
