Commentary on Sections Part 2 - Occupation contracts and Landlords Schedule 4 - Introductory standard contracts Paragraph 7
103.If the landlord gives the contract-holder a written statement that addresses both the introductory standard contract and the secure contract which may arise at the end of the introductory period, the landlord and contract-holder may, prior to the occupation date of the secure contract, agree to vary the secure contract addressed in the written statement. However, this is subject to sub-paragraphs (2) to (5), which provide:
	that there are limits on the extent to which fundamental terms can be varied (see section 108(1) to (5),
	that the landlord is required to give a written statement of a variation (and that compensation is payable if the landlord fails to comply) (see sections 109(1) to (3) and 110),
	that the specific requirements for varying rent or other consideration set out in sections 104(1) to (3) or section 105(1)(b) and (2) to (4) apply, and
	that the variation of rent or other consideration can take effect from the occupation date of the secure contract, or from a later date.
104.Section 20 provides for this paragraph to be a fundamental provision which is incorporated without modification as a term of all introductory standard contracts where the written statement is a ‘relevant written statement’ (that is, it addresses both the introductory standard contract and the secure contract that may follow).
