Where a customer of an electricity supplier is to be charged for his supply wholly or partly by reference to the quantity of electricity supplied, the supply shall be given through, and the quantity of electricity shall be ascertained by, an appropriate meter.

If the electricity supplier agrees, the meter may be provided by the customer; but otherwise it shall be provided by the electricity supplier (whether by way of sale, hire or loan).

F2An electricity supplier may refuse to allow one of his customers to provide a meter only if there are resonable grounds for his refusal.

The meter shall be installed on the customer's premises in a position determined by the electricity supplier, unless in all the circumstances it is more reasonable to place it outside those premises or in some other position.

If the customer refuses or fails to take his supply through an appropriate meter provided and installed in accordance with sub-paragraphs (2) and (3), the supplier may refuse to give or may discontinue the supply.

For the purposes of this paragraph a meter is an appropriate meter for use in connection with any particular supply if it is of a pattern or construction which, having regard to the terms on which the supply is to be charged for, is particularly suitable for such use.

Article 26 shall apply in relation to any dispute arising under this paragraph between F3an electricity supplier and a customer as if it were a dispute arising under Articles 19 to 25.

Pending the determination under Article 26 of any dispute arising under this paragraph, the meter and its provision and installation shall be such as the Director may direct; and directions under this sub-paragraph may apply either in cases of particular descriptions or in particular cases.

Part II shall apply as if any duty or other requirement imposed on F4an electricity supplier by directions under sub-paragraph (8) were imposed by directions under Article 26.
