The freeholder or head tenant of a commercial premises is free to dispose of their interest without reference to any tenant, as the rights of the tenant are, broadly speaking, unaffected. If the lease predates 1 January 1996, the original landlord will remain obliged to perform any covenants contained in the sublease—if the lease is after that time the provisions of the Landlord and Tenant (Covenants) Act 1995 will apply. The tenant continues in the same position as previously, and if the lease is subject to the provisions of Part II of the Landlord and Tenant Act 1954 (LTA 1954), security of tenure continues to apply.
