Section 134 and 135 – Variation and Limitation on variation
331.The purpose of these sections is to ensure that the parties to a fixed term standard contract cannot, at any time during the life of the contract, vary the contract so as to subvert the provisions of this Act that deal with the incorporation and modification of fundamental provisions (see section 20 and 21). The paragraphs that follow summarise the effect of the sections in greater detail but, generally, no variation will be permitted during the life of the contract that would result in the contract including terms that would not have been permitted under section 20 or 21 had they been included at the outset, or not including terms that would have been required to be included at the outset under section 20 or 21.
332.Where a term of a fixed term standard contract incorporates section 134 without modification, it will provide that the contract may only be varied by agreement between the landlord and the contract-holder or as a consequence of legislation made by the National Assembly for Wales or Parliament. Again, the approach is similar to that for secure contracts and periodic standard contracts (see sections 103 and 122). Any variations must be made in accordance with the term of the contract that incorporates section 135. Section 134 is a fundamental provision, and section 134(1)(b) and (2) are fundamental provisions which must be incorporated without modification.
