10 Common Billing Errors Hiding in Your Invoices

Commercial energy billing is notoriously complex, often leading to significant overcharges that go unnoticed for years. Our audits consistently reveal that nearly 90% of UK businesses are being overbilled in some capacity.

The Top 10 Billing Errors

• 1. VAT MiscalculationMany organizations, especially charities and care homes, are eligible for a 5% VAT rate but are charged the standard 20%.
• 2. Climate Change Levy (CCL) OverchargesExemptions for CCL are frequently missed by suppliers, particularly for businesses with specific industrial processes or charitable status.
• 3. Estimated Meter ReadingsSuppliers often rely on estimates rather than actual data, leading to inaccurate billing and potential "catch-up" charges.
• 4. Incorrect KVA (Available Capacity)Businesses often pay for a higher capacity than they actually use. Aligning your KVA with your peak demand can save thousands.
• 5. Reactive Power ChargesInefficient electrical systems can cause "lag," resulting in penalties that are often buried in the non-commodity section of your bill.
• 6. DUoS and TNUoS ErrorsDistribution and Transmission costs are complex and frequently misapplied based on the wrong voltage or region.
• 7. Feed-in Tariff (FiT) and RO LeviesThese green levies are often calculated incorrectly based on outdated consumption profiles.
• 8. Contract Rate MismatchesSuppliers sometimes fail to update their billing systems when a new, lower contract rate is agreed upon.
• 9. Duplicate InvoicingIn larger organizations with multiple sites, it's common for the same period to be billed twice under different account numbers.
• 10. Meter Multiplier ErrorsIf a meter multiplier is recorded incorrectly in the supplier's database, your consumption could be artificially inflated by a factor of 10 or more.

Identifying these errors requires a deep technical understanding of the UK energy market. Match Energy provides a comprehensive bill audit to recover these costs and ensure your future billing is accurate.
