Meter Point Administration Number
Structure
An MPAN is commonly separated into two sections, the core and the supplementary data. The core is the final 13 digits and is the unique identifier. The supplementary data gives information about the characteristics of the supply. The supplementary data is the responsibility of the supplier.
The full MPAN is required to be depicted on electricity bills (the boxes on the top and bottom line are generally unaligned):
The core data is on the second line, the supplementary data on the first.
Profile Class (PC)
The first two digits of a full MPAN reflect its profile class.
00
Half-hourly supply
01
Domestic Unrestricted
02
Domestic Economy 7
03
Non-Domestic Unrestricted
04
Non-Domestic Economy 7
05
Non-domestic, with MD recording capability and with LF less than or equal to 20%
06
Non-domestic, with MD recording capability and with LF less than or equal to 30% and greater than 20%
07
Non-domestic, with MD recording capability and with LF less than or equal to 40% and greater than 30%
08
Non-domestic, with MD recording capability and with LF greater than 40% (also all NHH export MSIDs)
Profile class 00 supplies are half-hourly (HH) metered, and supplies of the other profile classes are non-half-hourly (NHH) metered. A NHH supply must be upgraded to HH for:
Any Metering System where the average of the maximum monthly electrical demands in the three months of highest
demand, either in:
a. the previous twelve months; or
b. the period since the most recent Significant Change of Demand (whichever is the shorter) exceeds 100kW.
HH data is recorded by the meter and will be collected usually be either an onsite download, or via a GSM, SMS, GPRS or telephone line.
Domestic NHH import MPANs will always have a profile class of 01 or 02. Domestic NHH export MPANs are allocated a profile class of 08.
Meter Time Switch Class (MTC)
The MTC is represented by a three digit code that reflects the various registers a meter may have, whether it be a Single Rate, Day Night split, or even a Seasonal Time of Day.
MTC Ranges
000 – 399
DNO specific
400 – 499
Reserved
500 – 509
Codes for related Metering Systems – common across the Industry
