(1)Except in prescribed cases, the number of therms or kilowatt hours conveyed by a [F2 gas transporter] to premises, or to pipe-line systems operated by other [F2gas transporters], shall be calculated in the prescribed manner—
(a)on the basis of calorific values of the gas determined by the transporter in accordance with regulations under this section, or so determined by another [F2gas transporter] and adopted by the transporter in accordance with such regulations; or
(b)if and to the extent that regulations under this section so provide and the transporter thinks fit, on the basis of declared calorific values of the gas;
and regulations under this section shall be made by the Director with the consent of the Secretary of State.
(2)In this Part—
“calorific value”, in relation to any gas, means the number of megajoules (gross) which would be produced by—
the combustion of one cubic metre of the gas measured at a temperature of 15°C and a pressure of 1013.25 millibars; or
if regulations under this section so provide, the combustion of one kilogram of the gas,
containing in either case, if the Director so determines, such an amount of water vapour as is specified in the determination;
“declared calorific value”, in relation to any gas conveyed by a [F2gas transporter], means a calorific value declared by the transporter in accordance with regulations under this section, or so declared by another [F2gas transporter] and adopted by the transporter in accordance with such regulations.

(a)for requiring declarations of calorific values of gas conveyed by [F2gas transporters] to be made at such times and in such manner as the Director may direct;
(b)as to the times when such declarations are to take effect, and as to the manner in which the calorific values declared are to be made available to other licence holders and to the public;
(c)for imposing requirements on [F2gas transporters] as to the correlation between—
(i)the calorific values of the gas conveyed by them for any period; and
(ii)the calorific values declared by them for that period;
(d)for requiring [F2gas transporters] to carry out tests of gas for the purpose of ascertaining whether they are complying with the requirements of regulations made by virtue of paragraph (c) above;
(e)for requiring such tests to be carried out at such places or premises, at such times and in such manner as the Director may direct; and
(f)for requiring the results of such tests to be notified to the Director or to any person appointed under section 13(1) below, and to be made available to other licence holders and to the public.
