TO CONFIRM, THE COP/ISIT SUBMISSION PERIOD FOR LOT 1 (RESPONSIVE REPAIRS & VOIDS) IS NOW CLOSED (DEADLINE WAS 12:00 NOON ON 1ST JUNE 2026). THE PURPOSE OF THIS NOTICE IS TO INITIATE THE COP/ISIT STAGE FOR LOT 2 (MAJOR WORKS) The reason for this additional notice is due to a technical error with previous notice https://www.find-tender.service.gov.uk/Notice/042997-2026. Westminster City Council (the ‘Council’) has a statutory duty to deliver repair and maintenance services to its 21,000-strong housing stock, comprising approximately 43% leasehold properties, 57% tenanted homes and 145 High Rise Buildings (HRB) across the Borough. It is also worth noting that 41% of the Council’s housing stock is located within a conservation area, whereas 17% of the buildings are listed properties. Furthermore, the Council delivers major works and planned cyclical construction-based maintenance with the view of continuously improving the physical and social infrastructure of its housing stock. Currently housing repairs, maintenance and works are delivered via eight (8) Term Partnering Contracts (‘TPC’) which were procured in 2017 and 2019 for a period of up to ten (10) years as follows: • Responsive Repairs and Voids • Major Works (2 separate contracts covering North and South of the Borough) • Mechanical • Electrical • Domestic Heating • Lifts • Aids & Adaptations The Council is intending to re-procure these contracts based on revised scopes as part of an overarching Strategic Alliance Agreement, based on the FAC-1 Framework Alliance Agreement which all appointed contractors will be required to sign up to along with the contract documents specific to each requirement. Taking into account the differing expiry dates of the TPCs, the various Section 20 consultation requirements, as well as the indicative timelines associated with each retendering process, the Council determined that the re-procurements will be delivered in tranches. The Council issued a Preliminary Market Engagement (PME) Notice related to this procurement (Ref 2025/S 000-061916) on 2nd October 2025 (https://www.find-tender.service.gov.uk/Notice/061916-2025) supplemental to PME Notice with reference 2025/S000-022847 dated Monday 19th May 2025 (https://www.find-tender.service.gov.uk/Notice/022847-2025) for the purpose of inviting interested market suppliers to engage in detailed consultation around the proposed procurement model and the new contract opportunities for responsive repairs and voids and major works. For information, and in addition to the existing TPCs referenced above, the Council will also be procuring the following requirements through separately regulated processes: Establishment of a Planned Preventative Works Framework Specialist repair and maintenance contracts, including but not limited to minor works, roofing, damp and mould, plumbing and drainage Various Health & Safety Compliance contracts, and Establishment of a Professional Services Framework This tender notice provides details of the procurement for the Responsive Repairs & Voids contract and the Major Works contracts, which form part of the first tranche. The procurement is a lotted Procurement with Responsive Repairs & Voids constituting Lot 1 and Major Works constituting Lot 2. The procurement is to be conducted as a Competitive Flexible Procedure (CFP) and the structure will follow the same approach for both lots: a. Combined Conditions of Participation (COP) and Invitation to Submit Initial Tenders (ISIT) stage, b. Shortlisted Tenderers will be invited to participate in Technical and Commercial Dialogue, c. all Tenderers who participated in the Dialogue stage will be issued with an Invitation to Submit Final Tenders (ISFT), d. final tenders will be assessed and a most advantageous tenderer identified in line with section 19 of the Procurement Act 2023. However, the Council does not wish the same supplier to be awarded both lots and therefore has set bidding restrictions as outlined further in this notice. The Client reserves the right, at its sole discretion, to update, modify or issue supplementary documentation at any time during the procurement process to clarify any issue or amend any aspect of the associated tender documents by notification to the Tenderers in writing. The Council may, in its absolute discretion, exercise the option to extend any deadline in the event that subsequent documentation is issued or for any other reason.

The Programme forms part of the Council's wider strategic approach to the management, maintenance and improvement of its housing portfolio and is being delivered through a multi-tranche procurement programme supported by a Strategic Alliance model. The Council manages approximately 21,000 homes across the City, including a significant number of high-rise residential buildings, listed properties and buildings located within conservation areas. As part of Tranche 2 of the programme, the Council intends to procure a new borough-wide contract for Aids and Adaptations to replace the existing arrangement, which is due to expire in September 2027 subject to a 12-month extension being utilised.

The Royal Borough of Kensington and Chelsea (RBKC), working in partnership with Westminster City Council (WCC), is undertaking a market engagement exercise to gather information regarding premises that may be suitable for the delivery of the proposed Adult Social Care Mental Health Day Opportunities model. The proposed service model is expected to commence during Spring/Summer 2027 and is currently being developed following earlier market engagement activity. The model is anticipated to comprise three locality-based hubs across the borough: (i)North Hub (ii)South Hub (iii)Cultural Hub (located in the north of the borough) These hubs will provide accommodation to support staff delivery, key working, care coordination, group activities and service user engagement. The service model will also utilise community assets across the borough, including community venues, libraries, green spaces and other suitable facilities to support flexible delivery within local neighbourhoods. Through this engagement, the Council wishes to better understand: (i)The availability of suitable premises within the borough. (ii)Capacity, accessibility and physical characteristics of available spaces. (iii)Potential leasing, licensing or partnership arrangements. (iv)Opportunities to support community-based mental health day opportunities from existing assets. (v)Indicative costs, constraints and considerations relating to premises provision. Interested organisations, landlords, community organisations, faith groups, charities, social enterprises, property managers and other relevant stakeholders are invited to complete a short questionnaire. Information gathered will be used to inform future service design, commissioning and procurement planning. Participation in this engagement exercise will not confer any advantage or disadvantage in any future procurement process, nor does it constitute a call for competition. The Council reserves the right to amend its requirements and procurement strategy following completion of this engagement activity.
