Where a payment falls to be made in respect of an interest in a house under Schedule 24 (payments in respect of houses which are owner-occupied or used for business purposes), no payment shall be made in respect of that house under Schedule 23 (payments for well maintained houses) unless the other payment relates to part only of the house, and in that case such part only of the amount which would otherwise be payable in accordance with Schedule 23 shall be payable as may reasonably be attributable to the remainder of the house.

In Schedules 23 and 24 references to a demolition order do not include such an order in respect of a house already subject to a closing order so far as it affects any part of the house in relation to which a payment under either of those Schedules has fallen to be made in respect of the closing order.
