Commentary on Sections Part 10 – Miscellaneous Chapter 3 – Tenancies and Licences Existing before Commencement of This Chapter Sections 239 to 241 - Pre-existing licences and tenancies
503.Section 239 provides that, on the day it is brought into force (‘the appointed day’), no tenancy or licence can be:
	a restricted contract
	a protected shorthold tenancy;
	a secure tenancy;
	an assured tenancy (of any kind);
	an introductory tenancy; or
	a demoted tenancy.
504.No existing tenancies or licences are ended by this section. Rather, section 240 applies for the purposes of determining whether the tenancy or licence will convert into an occupation contract, and if so, what kind. The nature and status of pre-existing tenancies and licences which do not convert into an occupation contract will not be affected.
505.The existing terms of converted contracts continue to have effect providing they do not conflict with the fundamental provisions of the Act which become incorporated as terms of the contract. Conversely, supplementary provisions which apply to the occupation contract are incorporated into the contract unless they conflict with the existing terms of the contract. If a contract has been agreed between a landlord and tenant or licensee before the day that the relevant provisions of the Act come into force, but the occupation date falls after that date, the Act applies to the tenancy or licence as if it was made on the day the relevant provisions come into force.
