Article 21 Set-off of betterment against compensation
In determining the amount of compensation or purchase money payable to any person in respect of an interest in land acquired under this Order in a case where—
the person has an interest in any other land contiguous with or adjacent to the land so acquired; and
the value of the person’s interest in any such contiguous or adjacent land is enhanced by reason of the works authorised by this Order or any of them,
the amount of the enhancement in value shall be set off against the compensation or purchase money.
For the purposes of this article any reduction in expenditure that would have been required in order to comply with an obligation under any enactment with respect to any land is to be treated as an enhancement in the value of the interest in the land.
