Review and risk notes
Risks

The parties acknowledge that certain circumstances may arise during the Contract Term which necessitate modifications to the scope, requirements, or coverage of this Contract. Without limitation, such circumstances include, but are not restricted to, the following:

  • Change in Law (for example Hazards in Social Housing (Prescribed Requirements) (England) Regulations 2025 (“Awaab’s Law”), Building Safety Act 2022, or Decent Homes standard.
  • Conditions for Modification:
  • 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.
  • 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.
  • When Exercised: Upon formal enactment of new statutory requirements or publication of binding guidance by the Secretary of State.
  • 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.
  • 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’s 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.
  • General Safeguards
  • Modifications must be documented, justified, and approved in writing by the Contracting Authority.
  • Changes must be proportionate and necessary to ensure continued provision of services.
  • No modification to the contract can change the estimated value of the contract by more than 50% of the contract value.
