  "text": "(This note is not part of the Regulations)\nThe Regulations provide that, as an alternative to the standard method of charge provided for by section 12 of the Gas Act 1986 (whereby the number of therms supplied to a customer is calculated on the basis of the declared calorific value of the gas), the number of therms supplied by a public gas supplier may be calculated on the basis of actual calorific values of gas determined by the supplier in accordance with the Regulations. It is provided that the places and the times at which, and the manner in which, determinations of actual calorific values are to be made are to be those specified in directions made by the Secretary of State.\nProvision is made for circumstances when the actual calorific values of the supply to a particular area cannot be measured accurately at a particular measurement place, either because of an interruption in the flow of gas, or for other reasons, such as a defect in measuring equipment. In cases when there is an interruption in gas flow, the actual calorific value of the supply to the area in question is deemed to be equal to the declared calorific value in force with respect to that area – the value applied under the standard method of charge; in other cases it is deemed to be 95% of the declared value.\nThe Regulations provide for the publication of the results of determinations of actual calorific values and certain other information, and make provision for the furnishing of information to the Secretary of State.\nPenalties are provided for non-compliance.",
