Historical Audit™

New Energy performs a thorough and meticulous audit of the past 5 years of energy invoices for both public and private sector organizations. We identify regulatory anomalies, contractual misapplications, volume discrepancies, and unfair practices (detected in 87% of the cases studied), and we manage the claims through to the successful recovery of the owed amounts.

Billing consists of a small fixed subscription fee + a percentage of the amounts we successfully recover.

We go back in time — and you recover budgets to pay the right price!
Does it seem normal to you to pay more than you should?It’s very simple — let us help you!

Historical Audit™

Did you know that nearly 87% of our clients were paying more than they should have?

New Energy, the French leader in energy bill auditing, offers to verify this for you and, where applicable, secure the reimbursement of all amounts you are legally entitled to recover.

You have nothing to lose and everything to gain!

Here are two real examples:
- A municipality of 3,125 inhabitants in the Gard department
- A city of 44,600 inhabitants in the Bouches-du-Rhône department


Primarily focused on archived electricity billings, the results of our Historical Audit™ service make it an essential tool for financial management, as it can unlock very substantial budgets (several million euros identified and recovered to date!).

Developed in response to the alarming number of billing errors observed in the market, New Energy’s Historical Audit™ works to enforce your rights.

Chronic lack of time and resources, very expensive specialized tools, complexity, lack of clarity, and frequent changes in invoice formats and tariffs are the main reasons why so many anomalies go undetected. The widespread use of automatic direct debit further amplifies the issue.

Our Historical Audit™ is clear and risk-free: we collect, analyze, identify overbillings, and manage the entire reimbursement process, working with over 95% autonomy.

Obtaining the documents required for the audit of your past expenditures is quick and carried out as independently as possible. We may only occasionally request copies of invoices not available on your supplier portals or specific information regarding the usage of certain sites.

Important reminder:
€0 recovered = €0 billed and €0 in processing fees.
