40.This section provides for the increase of rent for an LDT at any time (notwithstanding the standard rent review procedures set out in the previous section) following from certain improvements made to the land by the landlord, provided the landlord serves notice of increase in rent within 6 months of the completion of the improvement. This provision for LDTs is similar to section 15 of the 1991 Act which applies to 1991 Act tenancies. By virtue of subsection (3), the increase in rent must be reduced proportionately where the improvement has attracted grant support to the landlord.
