You shouldn’t pay, or report on, something you haven’t used. And if you do get charged incorrectly for your utilities, we can help you get that money back – whether that’s electricity, gas, and water.
Historic Utility Bill Validation
Are you paying more than you should for your energy?
Utility bills are complex, and billing errors are more common than you might think.
At Sustainable Energy First, our Revenue Recovery team conduct historical utility bill audits to uncover mistakes hidden in past electricity, gas, and water charges. We help you recover lost revenue, so you only pay for what you’ve actually used.
Why conduct a historical utility bill audit?
The impact of incorrect utility charges can be massive, particularly across large and complex sites. Incorrect utility charges don’t just affect your bottom line; they can distort your carbon reporting and undermine your compliance.
Many organisations assume their current supplier is responsible for validating every cost and doing a deep dive audit. But did you know your energy supplier is under no obligation to check or correct your non-commodity charges? These hidden charges can make up to 60% of your total bill, and it’s where we often uncover errors.
Our team can complete a 6-year retrospective audit, analysing your bills line by line to identify overpayments and recover costs.
How does your business benefit?
- Risk and cost free process
- Return lost revenue to your organisation
