8.2 Licensed Distribution System Operators and Unmetered Supplies

8.2.1 A Licensed Distribution System Operator shall determine in relation to supplies of electricity connected to its Distribution System(s) or its Associated Distribution System(s) (if any) whether a supply of electricity to a particular inventory of Apparatus is to be treated for the purposes of the Code as an Unmetered Supply provided that, if such supply is separately measured and recorded through a SVA Metering System at or near to the point of supply to the Customer, the Licensed Distribution System Operator shall not determine that such supply is an Unmetered Supply.

8.2.2 Each Licensed Distribution System Operator acknowledges that, without prejudice to any other factor to which it may choose to have regard in making its determination, it would not expect to determine that a supply of electricity to a particular inventory of Apparatus is to be treated for the purposes of the Code as an Unmetered Supply unless it is technically impractical to install a Meter or to carry out meter readings or the cost of installation of a Meter or of carrying out meter readings is wholly disproportionate or the supply of electricity in question is both small (in kWh terms) and reasonably predictable.

8.2.3 If a Licensed Distribution System Operator determines in accordance with paragraph 8.2.1 that a supply of electricity to a particular inventory of Apparatus qualifies as an Unmetered Supply:

(a) it shall issue an Unmetered Supply Certificate to the Customer taking such supply in relation to such inventory;

(b) such Unmetered Supply Certificate shall state whether the Unmetered Supply to which it relates is an Equivalent Unmetered Supply or a Profiled Unmetered Supply, as agreed between the Licensed Distribution System Operator and the Customer.

8.2.4 The inventory of Apparatus relative to a particular Unmetered Supply shall be agreed between the Licensed Distribution System Operator on whose Distribution System or Associated Distribution System the Unmetered Supply takes place and the Customer taking such supply and the Licensed Distribution System Operator shall:

(a) ensure that any such inventory includes the means of identifying the type and number of items connected and taking supply, the location of such items, the wattage and the switch regime; and

(b) prepare and provide in accordance with the relevant BSC Procedure a summary inventory of Apparatus based on the information included in the detailed inventory of Apparatus.

8.2.5 A Licensed Distribution System Operator shall assign a unique SVA Metering System Number to each Unmetered Supply Certificate relating to an Equivalent Unmetered Supply on any of its Distribution System(s) or Associated Distribution System(s).

(a) a revised summary inventory of Apparatus (in the case of an Equivalent Unmetered Supply); and/or

(b) a new Estimated Annual Consumption (in the case of a Profiled Unmetered Supply).
