The Director may from time to time—
determine such standards of overall performance in connection with the provision of gas supply services by gas suppliers as, in his opinion, ought to be achieved by them; and
arrange for the publication, in such form and in such manner as he considers appropriate, of the standards so determined.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Different standards may be determined for different gas suppliers if the Director is of the opinion that the differences are such that no gas supplier would be unduly disadvantaged in competing with other gas suppliers.
Standards may be determined either as respects the provision of gas supply services generally or as respects the provision of such services to customers of a particular class or description.
It shall be the duty of every gas supplier to conduct his business in such a way as can reasonably be expected to lead to his achieving the standards set under this section.
