    Brief

    Oxfordshire County Council is seeking to procure a long-term retrofit service to improve energy performance in owner-occupied homes. The service will support residents throughout the complete lifecycle, including energy assessment, installation of low-carbon technologies, ongoing maintenance, system optimisation, customer support, and end-of-service arrangements. The Council is not seeking a model requiring residents to use consumer credit or regulated finance arrangements. The procurement process is subject to market engagement feedback and internal approvals, and is expected to follow a Competitive Flexible Procedure under the Public Contracts Regulations 2023, which will include multiple procurement stages. Interested suppliers must complete and submit the attached market engagement questionnaire by 19:00 on 26 September 2025. Market engagement responses received after this deadline will not be considered, though the expression of interest will remain open until the formal tender documentation is published.
