A customer of an electricity supplier shall at all times, at his own expense, keep any meter belonging to him in proper order for correctly registering the quantity of electricity supplied to him; and in default of his doing so the supplier may discontinue the supply of electricity through that meter.

An electricity supplier shall at all times, at his own expense, keep any meter let for hire or lent by him to any customer in proper order for correctly registering the quantity of electricity supplied and, in the case of pre-payment meters, for operating properly on receipt of the necessary payment.

An electricity supplier may remove, inspect and re-instal any meter by which the quantity of electricity supplied by him to a customer is registered, and shall, while any such meter is removed, fix a substituted meter on the premises; and the cost of removing, inspecting and re-installing a meter and of fixing a substituted meter shall be defrayed by the supplier.

Sub-paragraphs (2) and (3) are without prejudice to any remedy the supplier may have against the customer for failure to take proper care of the meter.
