(1)Where before 2nd June 1949 a premium has been paid on the assignation of a protected tenancy, then subject as hereinafter provided section 83 above shall not prevent the requiring or receiving on an assignation of that tenancy after 29th August 1954 of a premium not exceeding the amount hereinafter specified.
(2)The said amount is an amount which bears to the premium paid on the earlier assignation the same proportion as the period of the tenancy still to run at the time of the later assignation bears to the period of the tenancy still to run at the time of the earlier assignation, it being assumed that no power to determine the tenancy not yet exercised will be exercised either by the landlord or the tenant.
(3)Where before 2nd June 1949 a premium has been paid on more than one occasion on the assignation of the same tenancy any of those assignations except the last shall be disregarded for the purposes of this section.
(4)In so far as any premium paid on the assignation of a protected tenancy before 2nd June 1949 has been recovered under the provisions of section 88(1) below, the premium shall be treated for the purposes of the foregoing provisions of this section as not having been paid.
(5)Where apart from this subsection the requirement or receiving of a premium would be allowable both under the foregoing provisions of this section and under Schedule 7 to this Act, the foregoing provisions of this section shall have effect to the exclusion of the said Schedule 7.
(6)Any reference in this section to a premium does not include a premium which consisted only of any such outgoings, sum or amount as fall within section 83(3) above and, in the case of a premium which included any such outgoings, sum or amount, so much only of the premium as does not consist of those outgoings, sum or amount shall be treated as the premium for the purposes of this section.
