Bills, meters and consumption
Who does what in business energy metering?
Who is responsible when our business meter, data or connection needs attention?
Several organisations can sit behind one electricity supply. The supplier contracts with and bills the customer; the distribution network operator runs the local network; a meter operator installs and maintains relevant metering equipment; and data services collect, validate or aggregate readings for settlement. The exact arrangement depends on the supply and market rules.

What the roles mean
Your electricity supplier buys energy and bills the contracted customer. The distribution network operator, or DNO, owns and operates the regional wires and handles network faults and connection capacity. A Meter Operator, often shortened to MOP, is responsible for defined meter installation and maintenance services. A Data Collector obtains and validates consumption data, while a Data Aggregator combines validated data for settlement.
For gas, the labels and contractual chain differ, but the same discipline helps: separate the supplier, transporter or network, meter responsibilities and data services rather than assuming the supplier performs every task.
Why a decision-maker should care
Sending a problem to the wrong party creates delay. A billing error belongs first with the supplier; a local power cut is a network matter; a failed communications link or meter exchange may involve metering parties; and incomplete interval data may require coordination between supplier and appointed data services. Contractual responsibility should be checked rather than inferred from a logo on the meter.
Where to find the information
The invoice normally identifies the supplier and MPAN or MPRN. Contracts, appointment schedules, meter labels and supplier portals may identify the meter operator or data service. The postcode identifies the regional network operator, but the supply-point identifier should remain the primary key in your estate register.
What to ask next
Record who is appointed for each supply, who may instruct them, when each appointment ends and which party owns the data. Ask for an escalation route for billing, meter faults, data gaps, planned capacity changes and emergencies.
When specialist help may be useful
Help may be useful where half-hourly data is persistently missing, a meter change affects billing, several parties disagree about responsibility, the site needs more capacity or an estate has inconsistent metering appointments. Ask the adviser to state both the root cause and the party contractually responsible for the remedy.
