Without limitation, such circumstances include, but are not restricted to, the following:\n- Change in Law (for example Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025 (\u201cAwaab\u2019s Law\u201d), Building Safety Act 2022, or Decent Homes standard.\n\u2022 Conditions for Modification:\n\u2022 Trigger: Any amendment, secondary legislation, or statutory instrument issued, introduction, or expansion of prescribed requirements under a regulation or act that directly impacts or materially alters compliance obligations of Stonewater as a landlord.\n\u2022 Known Risk: Legislative reform is anticipated; therefore, modifications may be exercised where changes impose new duties (e.g., mandatory response times, safety case reviews, resident engagement requirements and reporting obligations, or remediation standards) are introduced.\n\u2022 When Exercised: Upon formal enactment of new statutory requirements or publication of binding guidance by the Secretary of State.\n\u2022 Scope of Modification: Limited to adjustments necessary to ensure compliance with the updated legislation while maintaining continuity of contracted services without altering its fundamental nature. It would not be in the publics interest to award another contract due to the time required to re-procure and the associated costs to Stonewater and their customers. \n- Tenderers should note that while the current scope of this contract reflects the housing stock and operations as they stand at the time of publication, Stonewater acknowledges the potential for future growth. This may include, but is not limited to, the acquisition of additional housing stock or merger with other housing associations. As such, the successful provider may be required to accommodate an increase in the volume or geographical spread of services delivered under this contract, proportionate to the organisation\u2019s growth. While the timing and scale of such changes are currently unknown, tenderers are advised to consider flexibility and scalability in their proposals, to ensure capacity to support future expansion should it occur during the lifetime of the contract. \n- General Safeguards\n\u2022 Modifications must be documented, justified, and approved in writing by the Contracting Authority.\n\u2022 Changes must be proportionate and necessary to ensure continued provision of services.\n\u2022 No modification to the contract can change the estimated value of the contract by more than 50% of the contract value.",
