An MPAN (Meter Point Administration Number) is a unique number to the property.

called a Supply Number but it should not be confused by your customer reference

Every property has a profile class.
Profile classes are used where half -hourly metering is not installed and
provides the electricity supplier with an expectation as to how electricity
will be consumed throughout the day.
From a domestic customer viewpoint we are interested in two classes 01 and
02. Other classes that exist are 03, 04, 05, 06, 07, and 08. Where half-hourly
metering is installed (large consumers) the profile class in 00.
Detailed below are the profile classes used as guidance to show your likely
electricity consumption throughout the 24 hour period. You will notice that
summer and winter figures are different:
01 Domestic Unrestricted
02 Domestic Economy 7
03 Non-Domestic Unrestricted
04 Non-Domestic Economy 7
05 Non-Domestic Maximum Demand 0-20% Load Factor
06 Non-Domestic Maximum Demand 20-30% Load Factor
07 Non-Domestic Maximum Demand 30-40% Load Factor
08 Non-Domestic Maximum Demand >40% Load Factor
Meter Time Switch Code (MTC)
The Meter Time Switch Code indicates how many registers (set of meter reads
or dials) your electricity meter has and what times they will operate during
the day. The Meter Time Switch Code will show if your meter has two registers,
one which records day consumption, the other night.
Line Loss Factor (LLF)
The Line Loss Factor code stipulates the expected costs the distribution company
will charge the supplier for using the cables and network in your region. This
Line Loss Factor code will also indicate to the electricity supplier the potential
charges incurred, due to loss of energy incurred whilst getting the electricity
supplier to your meter.
The Distributor ID will identify the local Distribution Company for your electricity
supply. The Distribution company is responsible for management of the distribution
system and electricity wires which transports the electricity to your meter.
