Facilities and rights for alternative apparatus
6.—(1) Where, in accordance with the provisions of this Part of this Schedule, the undertaker affords to Centrica facilities and rights for the construction and maintenance in land of the undertaker of alternative apparatus in substitution for the apparatus to be removed, those facilities and rights shall be granted upon such terms and conditions as may be agreed between the undertaker and Centrica and shall be no less favourable on the whole to Centrica than the facilities and rights enjoyed by it in respect of the apparatus to be removed unless agreed by Centrica.
(2) If the facilities and rights to be afforded by the undertaker and agreed with Centrica under (1) above in respect of any alternative apparatus, and the terms and conditions subject to which those facilities and rights are to be granted, are less favourable on the whole to Centrica than the facilities and rights enjoyed by it in respect of the pipeline to be removed and the terms and conditions to which those facilities and rights are subject, the matter shall be referred to arbitration and, the arbitrator shall make such provision for the payment of compensation by the undertaker to Centrica as appears to the arbitrator to be reasonable having regard to all the circumstances of the particular case.
