Summary of the contracting process

Renfrewshire Council is procuring external retrofit works for its council-owned and mixed-tenure homes across Renfrewshire. The work is intended to improve buildings’ energy efficiency and thermal performance and support Net Zero and low-energy standards. It covers retrofit design, build and delivery, issued through task orders. For the first two years, the Council will provide the designs and the appointed contractor will supply and install the works. For the extension period, the contractor will take on both design and construction. This is a housing retrofit works contract, including external building improvements.

The Council invited suppliers to participate through a two-stage restricted procedure. This first stage is for requests to participate; five candidates are intended to be shortlisted and invited to tender in the second stage. The participation deadline was 15 October 2026 at 12 noon, following an extension, with invitations to tender estimated for 29 October 2026. The contract period is seven years. Its estimated value is £135 million. Bids are evaluated on quality (60%) and price (40%). Suitability criteria and the minimum requirements for selection are set out in the Invitation to Participate documents. A recommendation was anticipated for the Council’s policy board on 11 February 2027, with the date to be confirmed in the second-stage invitation.

This opportunity suits a main contractor able to deliver external retrofit across a substantial portfolio of residential properties and work to improve energy and thermal performance. Contractors need supply-and-install capability for the initial phase, with the ability to assume design as well as construction responsibilities during the extension period. The Council requires named staff and their qualifications. The contract includes Community Benefits, Fair Work First and key performance indicators, and the successful supplier will need to consult the Council’s property insurers at the early design stage. At the documentation stage, the recommended tenderer must provide equalities and prompt-payment documents, waste-carrier details, proposed subcontractor information, guarantees and collateral warranties. Selection is competitive, with five candidates intended to reach the tender stage.
