Bill validation is the process of checking your energy invoices to ensure they are accurate, comply with your contract terms, and are free from billing errors.
Energy billing often involves complex tariffs, industry charges, taxes, and consumption data, meaning it is possible for businesses to end up overpaying if mistakes are made.
A comprehensive bill validation examines every element of your energy invoices, from meter readings and consumption figures to supplier rates, pass-through charges, taxes, and contractual agreements, to identify discrepancies, overcharges, and areas where costs may have been incorrectly applied.
For organisations managing multiple sites or large energy portfolios, even small errors can add up into significant unnecessary expenditure over time.
By ensuring every invoice is correct, businesses can improve cost control, make budgeting easier and gain confidence that their energy spend reflects their actual usage.
At Consultus, we have our very own in-house bill validation system designed to manage electricity, gas and water contracts.
As part of our process, each invoice will undergo checks to ensure:
Once the invoices have been validated, Consultus will access supplier portals and communicate directly with utility providers, managing queries through to resolution and chasing outstanding invoices to maintain accuracy and ensure the maximum possible savings for your business.

In today’s volatile energy markets, effective risk management is essential. At Consultus, we can help businesses understand and control exposure to price volatility, supply uncertainty, and regulatory change across electricity, gas, and water.

Consultus’ CORA helps identify potential savings or overpayments from historical energy bills.
If savings are identified, a percentage of the recovered value is charged as a fee for the work completed.

We offer a full range of bureau services, data and analytics including Bill Validation, Historical Audits, Net Zero Reporting, Cost/Consumption Reporting and Tenant Billing and Accrual Reporting, all via one bespoke online portal.
Common billing issues include incorrect meter readings, inaccurate consumption data, incorrect contract rates, duplicate charges, missing credits, and errors in taxes or non-commodity charges. Having an external body validate your bills can spot errors that could be costing your business money.
Savings can vary depending on the size of your energy portfolio and the kinds of billing errors uncovered. Even small inaccuracies can add up to significant costs over time, particularly for larger organisations. Consultus has saved our clients a total of £16,948,698 through our services.
