Bills, meters and consumption
How to read a commercial energy bill
What are we actually paying for on our energy bill?
A commercial energy bill combines identification information, meter readings or consumption, contracted prices and other charges. Start by confirming the customer, site, billing period, MPAN or MPRN and whether the readings are actual or estimated. Then separate usage-based charges from fixed and pass-through charges.

Confirm the bill belongs to the right supply
Match the legal entity, address and supply-point identifier to your internal site record. An electricity MPAN or gas MPRN identifies a supply point independently of the account name.
Separate the components
Identify the billed consumption, unit rate, standing charge, taxes and other contract or network-related components. Check whether each figure is fixed, variable or passed through under the contract.
- Billing dates and meter-reading dates
- Actual or estimated reading
- kWh consumed
- Unit price and standing charge
- CCL and VAT treatment
- Adjustments, credits and previous balance
Use the bill as evidence, not the whole picture
A single bill rarely shows the full annual pattern. Compare several periods, validate against meter data where available and investigate unexplained differences between sites or years.
