Where a notice has been given in respect of any property under the last preceding subsection, the responsible authority shall be entitled to make a fresh claim against the person who gave the notice in respect of any increase in the value of the property due to the coming into operation of any provision contained in the scheme or by the execution by the authority of any work under the scheme—

b
on the taking place at any time within the said period of fourteen years of a change of use of the property;

5
In assessing the amount of any sum payable under this section in respect of any property, account shall be taken—
a
of any principal sum paid or payable to the responsible authority in respect of the property under a claim previously made under this section; and
b
of any gift of property whether real or personal, or any concession made or any works executed under arrangement with the responsible authority, by any person against whom the claim under this section in respect of the property is made or his predecessors in title, with a view to facilitating the making or carrying into effect of the scheme.
6
Any sum recoverable under this section may be paid either immediately or by such instalments spread over a period not exceeding thirty years as may be agreed or determined under this Act, and where payment is made by instalments interest at such rate as may from time to time be fixed by the Treasury shall be chargeable on the aggregate amount of the instalments for the time being outstanding, but notwithstanding any such agreement or determination the person from whom such instalments are due may, on giving not less than six months' notice in writing to the responsible authority of his intention so to do, pay to them the whole of any outstanding instalments, together with any interest accruing due thereon to the date of payment.
7
A person who gives a notice under subsection (1) of this section shall, within one month after the date on which any such disposition as is mentioned in paragraph (a) of subsection (2) of this section takes effect, or any such change of use as is mentioned in paragraph (b) of the said subsection (2) takes place, give written notice thereof to the responsible authority and shall, within one month after receiving from the responsible authority a demand in that behalf (which demand shall be made not later than the expiration of two months after the giving of the notice), furnish to the authority such particulars as they may reasonably require for the purposes of this section :

Where any provision of a scheme, whether made under this Act or under any Act repealed by this Act, is revoked by a subsequent scheme, no property shall be deemed to be increased in value by any provision contained in the subsequent scheme if and in so far as that provision is the same, or substantially the same, as a provision contained in the scheme so revoked :
Provided that, if at the date when the revocation of the said scheme becomes operative there is still outstanding any claim in respect of an increase in the value of any property duly made thereunder, or the time originally limited for making such a claim has not expired, any such outstanding claim, and any such claim made within the time so limited, shall be entertained and determined and may be enforced, in the like manner in all respects as if all the provisions of the earlier scheme had continued in operation.
11
In this section the expression " disposition " means a disposition by way of sale (including a sale in consideration of a rentcharge or other periodical payment) or by way of lease or tenancy agreement for a period of not less than three years, and references to the person who gives a notice under subsection (1) of this section shall, where a devolution of the property to which the notice relates has occurred since the notice was given, be construed as references to the person on whom the property to which the notice relates last devolved before the date on which a disposition takes effect or a change of use takes place.
12
For the purposes of this section a change of use of property shall not be deemed to have occurred if the character of the new use is similar to that of the previous use.
