43.—(1) Subject to the following provisions of this paragraph, TfL must repay to a specified undertaker the reasonable expenses incurred by that specified undertaker in, or in connection with—
(a)the inspection, removal and relaying or replacing, alteration or protection of any apparatus or the construction of any new apparatus under any provision of this Part of this Schedule (including any costs reasonably incurred or compensation properly paid in connection with the acquisition of facilities and rights or exercise of statutory powers for such apparatus);
(b)the cutting off of any apparatus from any other apparatus, or the making safe of any redundant apparatus in consequence of the exercise by TfL of any power under this Order; and
(c)the survey of any land, apparatus or works; the inspection, superintendence and monitoring of works; or the installation or removal of any temporary works reasonably necessary in consequence of the exercise by TfL of any power under this Order; and any other work or thing rendered reasonably necessary in consequence of the exercise by TfL of any such power,
within a reasonable time of being notified by the specified undertaker that it has incurred such expenses.
(2) The value of any apparatus removed under the provisions of this Part of this Schedule is to be deducted from any sum payable under sub-paragraph (1), that value being calculated after removal.
(3) If in accordance with the provisions of this Part of this Schedule—
(a)alternative apparatus of better type, of greater capacity or of greater dimensions is placed in substitution for existing apparatus of worse type, of smaller capacity or of smaller dimensions, except where this has been solely due to using the nearest currently available type; or
(b)apparatus (whether existing apparatus or apparatus substituted for existing apparatus) is placed at a depth greater than the depth at which the existing apparatus was situated,
and the placing of apparatus of that type or capacity or those dimensions or the placing of apparatus at that depth, as the case may be, is not agreed by TfL or, in default of agreement, is not determined by arbitration in accordance with article 45 (arbitration) to be necessary, then, if such placing involves cost in the construction of works under this Part of this Schedule exceeding that which would have been involved if the apparatus placed had been of the existing type, capacity or dimensions, or at the existing depth, as the case may be, the amount which apart from this paragraph would be payable to the specified undertaker in question by virtue of sub-paragraph (1), is to be reduced by the amount of that excess.
(4) For the purposes of sub-paragraph (3)—
(a)an extension of apparatus to a length greater than the length of existing apparatus must not be treated as placing of apparatus of greater dimensions than those of the existing apparatus, except in a case where the apparatus as so extended serves a purpose (either additional to or instead of that served by the existing apparatus) which was not served by the existing apparatus; and
(b)where the provision of a joint in a cable is agreed, or is determined to be necessary, the consequential provision of a jointing chamber or of a manhole must be treated as if it also had been agreed or had been so determined.
(5) An amount which apart from this sub-paragraph would be payable to a specified undertaker in respect of works by virtue of sub-paragraph (1) must, if the works include the placing of apparatus provided in substitution for apparatus placed more than 7 years and 6 months earlier so as to confer on the specified undertaker any financial benefit by deferment of the time for renewal of the apparatus in the normal course, be reduced by the amount which represents that benefit as calculated in accordance with the Code of Practice entitled “Measures Necessary where Apparatus is Affected by Major Works (Diversionary Works)” and dated June 1992 and approved by the Secretary of State on 30th June 1992, as revised and re-issued from time to time.
(6) In any case where work is carried out by TfL under paragraphs 40(6) to (8) and, if such work had been carried out by the specified undertaker, the repayment made to the specified undertaker under sub-paragraph (1) would fall to be reduced under sub-paragraphs (3) to (5), the specified undertaker must pay to the TfL such sum as represents the amount of that reduction.
