Leasehold Reform, Housing and Urban Development Act 1993

5 (1) Where the landlord will suffer any loss or damage to which this paragraph applies, there shall be payable to him such amount as is reasonable to compensate him for that loss or damage.

(2) This paragraph applies to—

(a) any diminution in value of any interest of the landlord in any property other than the tenant’s flat which results from the grant to the tenant of the new lease; and

(b) any other loss or damage which results therefrom to the extent that it is referable to the landlord’s ownership of any such interest.

(3) Without prejudice to the generality of paragraph (b) of sub-paragraph (2), the kinds of loss falling within that paragraph include loss of development value in relation to the tenant’s flat to the extent that it is referable as mentioned in that paragraph.

(4) In sub-paragraph (3) “development value”, in relation to the tenant’s flat, means any increase in the value of the landlord’s interest in the flat which is attributable to the possibility of demolishing, reconstructing, or carrying out substantial works of construction affecting, the flat (whether together with any other premises or otherwise).
