Landlord and Tenant Act 1954

1 (1) Where—

(a) the tenant retains possession of the dwelling-house by virtue of subsection (1) of section six of this Act, and

(b) by virtue of an agreement or of a determination of the court the landlord is required to carry out initial repairs to the dwelling-house,

then if on an application made by the tenant during the period of the statutory tenancy the court is satisfied that the initial repairs have not been carried out within a reasonable time in accordance with the agreement or determination the court may by order direct that, until the discharge of the order as hereinafter provided or the end of the period of the statutory tenancy, whichever first occurs, the rent payable in respect of the dwelling-house shall be reduced to such amount specified in the order as the court may think just having regard to the extent to which the landlord has failed to comply with the agreement or determination.

(2) Where the court under the last foregoing sub-paragraph orders a reduction of rent, the court may further order that during the same period any instalments of a payment for accrued tenant's repairs shall be suspended.

(3) An order under this paragraph may include a provision that the reduction of rent shall take effect from a specified date before the making of the order, being such date as the court thinks just having regard to the landlord's delay in carrying out the initial repairs; and where an order contains such a provision then, in addition to the reduction ordered by virtue of sub-paragraph (1) of this paragraph, such number of payments of rent next falling due after the date of the order shall be reduced by such amount as may be specified in the order for the purpose of giving effect to the said provision.
