UK4 Tender Notice for Penrhys Regeneration Project Development Partner

Trivallis are procuring a development partner for our Penrhys Regeneration project. The partner will work with Trivallis to design and subsequently deliver a new housing development in Penrhys, invest in mixed-tenure housebuilding and manage all stages of the process from planning through to sales and after-care. Social value requirements will be included as part of the project and residents have been at the heart of the process, meeting with architects, planners and our team to shape the future of their community. Preliminary market engagement was undertaken in accordance with section 16(1) of the Procurement Act 2023. A Preliminary Market Engagement Notice was published on Sell2Wales on 6 August 2025. This notice provided for interested parties to register their interest via email. A briefing pack was made available which set out the context of the project, Trivallis’ objectives and a number of supporting documents. A copy of the briefing pack is included in the Portal. A number of participants who registered interest also opted to join a call to discuss their feedback on the proposed process and the information provided. The feedback provided confirmed that the market generally did have the ability and appetite to deliver against Trivallis’ minimum requirements and in line with the proposed commercial structure, as well as delivering added social value and engagement with local communities as part of the project. Phase one will deliver circa 120 new homes as part an exciting long-term plan for around 800-900 homes across the site. A key principle of the project is to adopt a tenure neutral approach to the delivery of new affordable homes and homes for sale. Trivallis will fund and retain the affordable housing units and the market housing properties will be funded and sold by the successful bidding organisation. The estimated contract length is from week commencing 29th June 2026 to end of June 2036, with an estimated gross development value of £200,000,000 (two hundred million pounds). A contract extension allowance is made for up to 5 (five) years of incremental extensions, depending on the progression of the project. Trivallis will be using the competitive flexible procedure as it appears in the Procurement Act 2023 under section 20 (2) (b). This competitive flexible procedure will be conducted in three (3) stages. The three (3) stages are described in more detail below. Stage 1: Invitation to participate; this stage is to secure a credible shortlist of up to three potential partners.

The initial proposals will not be evaluated but will be a work in progress against each of the submission requirements. The initial proposals will be used to inform discussions. Trivallis will hold up to two sessions with each bidder to discuss initial proposals aligned with the assessment methodology and award criteria set out in in Appendix 7 of the Tender Document. A presentation to tenant representatives will also be required. Feedback will be provided by the Trivallis evaluation team to enable Suppliers to refine their submissions. A session will also be offered to discuss commercial principles.
