Meter Point Administration Number
The 13-digit number that uniquely identifies a UK electricity supply point on the central industry database.
An MPAN is the unique identifier for a UK electricity supply point. Every electricity meter in Great Britain has one, and it is the reference that suppliers, network operators and meter operators use to coordinate everything from a tariff change to a fault response. Once allocated, an MPAN does not change; the customer, the supplier and the meter can all change, but the MPAN stays attached to the supply point.
The full MPAN is twenty-one digits but the part most people see is the bottom-line core MPAN of thirteen digits. The top line — the profile class, the meter time-switch class, the line loss factor class and the distributor identifier — encodes how the supply is metered and where on the network it sits.
- Profile class: 1 and 2 are domestic; 3 to 8 are non-domestic profile-class (NHH); 0 indicates half-hourly.
- MTC: meter time-switch class — single rate, two rate (Economy 7), and so on.
- LLFC: line loss factor class — used in calculating distribution losses.
- Distributor ID: the regional Distribution Network Operator identifier.
Validating the MPAN against the central industry database is the first step in any procurement audit. The registered occupier, the contract end date and the recorded annual quantity all attach to the MPAN, and a misallocated MPAN is one of the commonest sources of deemed-contract overcharge after a change of tenancy.
