The National Grid (Hinkley Point C Connection Project) Order 2016

22.—(1) If the relevant highway authority, after giving to the undertaker not less than 28 days’ notice (or, in case of emergency, such notice as is reasonably practicable) of its intention to do so, incurs any additional expense in the signposting of traffic diversions, in the diversion of footpaths, in the taking of other measures in relation to that or in the repair of any highway by reason of the diversion to that traffic from a road of a higher standard, in consequence of the construction of the works authorised by this Order, the undertaker must pay to the relevant highway authority the amount of any such expense reasonably so incurred.

(2) An amount which apart from this sub-paragraph would be payable to the relevant highway authority by virtue of this paragraph in respect of the repair of any highway must, if the highway fell or would have fallen due for repair as part of the maintenance programme of the relevant highway authority at any time within 10 years of the repair being carried out by the undertaker, so as to confer on the relevant highway authority financial benefit (whether by securing the completion of overdue maintenance work for which the relevant highway authority is liable or by deferment of the time for such work in the ordinary course), be reduced by the amount which represents that benefit.
