Section 6: Permitted rent: leases replacing pre-commencement leases
Section 6 allows for rent other than a peppercorn rent in the case of non-statutory (‘"voluntary’") lease extensions, where a tenant is granted a lease that replaces a lease that was granted prior to commencement of the applicable provision of the Act (referred to as a "pre-commencement lease" – a term defined in subsection (8)(a)).
	The permitted rent during the period up to the expiry date specified in the pre-commencement lease is a rent not exceeding the rent that would have been payable under the pre-commencement lease in respect of that period. The permitted rent for the period of the new lease following the expiry date specified in the pre-commencement lease is to be a peppercorn rent.
	Subsection (5) makes provision for a case where a lease that is itself a replacement lease is replaced by a new lease. The permitted rent for non-statutory extensions of pre-commencement leases can apply to a replacement lease which includes some premises not demised by the pre-commencement lease (i.e. where there has been a deemed surrender and regrant to increase the property demised on a lease).
	The permitted rent for non-statutory extensions of pre-commencement leases can also apply to a replacement lease that does not extend beyond the end of the term of the pre-commencement lease. This includes a surrender and regrant of a lease where there is not a lease extension, such as to extend the extent of the demised property. Rent can continue to be charged at the existing rate on the balance of the term of the existing lease, while any extension to the lease may only charge a peppercorn rent.
	Subsections (6) and (7) makes provision for a case where the pre-commencement lease is a relevant shared ownership lease (as defined in subsection (9)).
