What is Utility Bill Auditing?
A utility bill audit reviews your business energy invoices, usage data, and contract terms to identify billing errors, incorrect charges, and missed savings opportunities. It helps ensure your business only pays for the energy it actually uses while remaining compliant with industry regulations.
Button TextWhy it matters in 2026?
Pass-through charges can make up to 60% of a utility bill, meaning even small inaccuracies can result in significant overpayments. Businesses are also facing rising TNUoS and DUoS charges, changes to CCL and VAT eligibility, and upcoming BICS exemptions from 2027.
Button TextHow does a utility bill audit work?
A utility bill audit involves reviewing invoices, validating usage against metering data, checking non-commodity charges, and comparing supplier rates with contract terms. This process helps identify discrepancies, incorrect penalties, and opportunities to improve cost efficiency.
