Paragraph 6 I1

Where, in accordance with this Part, the relevant undertaker affords to a utility undertaker facilities and rights for the construction and maintenance in land of the relevant undertaker of alternative apparatus in substitution for apparatus to be removed, those facilities and rights must be granted on such terms and conditions as may be agreed between the relevant undertaker and the utility undertaker in question or in default of agreement settled by arbitration in accordance with article 41.

In settling those terms and conditions in respect of the alternative apparatus to be constructed, the arbitrator must—

If the facilities and rights to be afforded by the relevant undertaker in respect of any alternative apparatus, and the terms and conditions subject to which those facilities and rights are to be granted, are in the opinion of the arbitrator less favourable on the whole to the utility undertaker in question than the facilities and right enjoyed by it in respect of the apparatus to be removed and the terms and conditions to which those facilities and rights are subject, the arbitrator must make such provision for the payment of compensation by the relevant undertaker to that utility undertaker as appears to the arbitrator to be reasonable, having regard to all the circumstances of the particular case.
