TEN-2627-047 (PA2023) – Asset Allocation System

• How the procedure runs: This procurement will be conducted using a competitive flexible procedure under section 20 of the Procurement Act 2023. Stage 1: Conditions of Participation and supplier selection Interested suppliers must submit the Procurement Specific Questionnaire (PSQ) and the required Central Digital Platform supplier information by the stated deadline. Nest will assess the pass/fail Conditions of Participation and the scored technical selection questions set out in the PSQ. Nest will also undertake the information security assessment described in the procurement documents. Suppliers that satisfy the Conditions of Participation and meet the required selection standards will be invited to continue to the tender stage. Stage 2: Full tender submission and written evaluation Selected suppliers will submit one full tender comprising the quality response, commercial response and other mandatory documents identified in the Invitation to Tender. Tenders will be evaluated against the published award criteria, sub-criteria, weightings and scoring methodology. The written quality response will account for 70% of the quality assessment. Stage 3: Demonstration shortlist and evaluation Following evaluation and moderation of the written tenders, Nest intends to invite up to three of the highest-ranked suppliers to participate in scored demonstrations. The demonstrations will be used to validate the suppliers’ written responses and will account for 30% of the quality assessment. The demonstration arrangements and criteria will be applied consistently to all shortlisted suppliers. Stage 4: Final evaluation and award Nest will combine the written tender, demonstration and commercial scores in accordance with the published methodology to identify the most advantageous tender. Nest may seek clarifications where permitted, but suppliers will not normally be permitted to make material changes to their tenders. Negotiation and refinement No negotiation round or invitation to submit revised or best-and-final tenders is planned. Nest does not intend to refine the published award criteria or weightings after receipt of tenders. Any clarification, specification or optimisation requested by Nest will not permit changes to the essential aspects of the procurement or give any supplier an unfair advantage. Nest reserves the right to modify the procedure only in accordance with the Procurement Act 2023 and the procurement documents. A Preliminary Market Engagement Notice was not published because the engagement took place through a series of structured, informal and exploratory conversations with providers known to be active in the relevant market, before the formal procurement was launched. The engagement was used to test the maturity and shape of the market and to inform the scope and feasibility of the emerging requirements. It did not involve evaluation, scoring, shortlisting or any commitment concerning participation in the procurement. To support transparency and ensure that no participating supplier receives an unfair advantage, a high-level, anonymised summary of the engagement has been published with the procurement documents as Annex F.
