Description

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.

Description

This lot covers planned and cyclical major works to the Council’s housing stock, delivered broadly in line with the RIBA Plan of Work 2020. Contractors may be instructed to undertake a range of capital improvements, component replacements, and major repairs as detailed in the Term Brief.

Following internal review and approval of the Task Proposal, the Council shall issue to an Order thus formally instructing the relevant contractor to undertake the required works.

The Contract is to be procured for an initial term of five (5) years with an option to extend for further periods of three (3) years and two (2) years at the Council’s discretion – extensions will be subject to budget availability, value for money considerations and the individual Contractor’s performance during the initial term.

TUPE Transfer risk - Mobilisation delays, employment claims, service continuity issues in the event the contract start date cannot be achieved and cost uplifts due to unplanned extensions.

Change of law/legislation - Breach of statutory duties leading to regulatory action brought against the Council in the form of inspections and possible enforcement notices.

Data Migration and Transition Risk - Errors or incomplete migration may disrupt live repairs operations.

Integration and Interface Failures - The contractor’s job management system must interface with the new Housing Management System. Technical failures may cause delays, duplicate effort or manual workarounds.

Procedure type

Competitive flexible procedure

Competitive flexible procedure description

The following stages will be carried out under the Competitive Flexible Procedure for each Lot but on different timetables. The Lots and their indicative timetables are linked through the bidding restrictions :

Stage 1 – Combined Participation and Invitation to Submit Initial Tenders (ISIT)

Stage 2 – Dialogue

Stage 3 – Invitation to Submit Final Tenders (ISFT)

Stage 4 – Preferred Tenderer and Contract Award

The number of tenderers will be reduced at each stage as set out in the ISIT for the relevant Lot. An indicative procurement timetable has been provided for each Lot within the Associated Tender documents.

Stage 1 - The Council is conducting a combined Conditions of Participation (COP) and Invitation to Submit Initial Tender (COP/ISIT) stage. Tenderers will be required to submit a fully completed COP Submission Document along with responses to each section of the ISIT Submission Document (the document focused on the award criteria and any sub-criteria) and the completed Bid Forms. When assessed, Tenderers who do not meet the minimum COP requirements will be rejected and not considered any further. Tenderers who meet or exceed the minimum COP requirements will have their ISIT submission assessed. Subject to certain caveats in the rules for each Lot (explained in the associated tender documents), it is intended by the Council that the top 3 highest ranking Tenderers will be shortlisted and will proceed to Stage 2 (Dialogue).

Stage 2 - Dialogue sessions. Stage 2 of the CFP process will enable the Council to clarify its expectations, ensure that the proposed solutions are deliverable, explore the potential for further savings for the Council and incorporate any necessary refinements to the technical requirements where doing so improves service quality, operational efficiency or commercial viability. All Tenderers involved in Stage 2 will proceed to Stage 3.

Stage 3 - Invitation to Submit Final Tenders (ISFT) - The final tender submissions will be assessed against the award criteria and the Tenderer(s) with the highest overall combined score for the relevant Lot will be recommended as the Most Advantageous Tender.

Stage 4 - Preferred Tenderer and Contract Award – Following a Completeness and compliance review a Preferred Tenderer will then be identified on the basis of the Final Tender representing the Most Advantageous Tender (MAT).

In accordance with section 24 of the Procurement Act 2023, prior to the Council issuing any ISFT, the Council may refine the award criteria for this procurement. This may include consequential refinement to the relative importance of the award criteria as specified in the associated tender documents. Where it does so, the Council will republish or provide again this Tender Notice and any associated tender documents affected by the refinement(s). Without limitation, the Council anticipates that refinements in accordance with section 24 may include adjustments to the percentage weightings of any one of the Tier 4 Quality Award Criteria set out in the associated tender documents following completion of Dialogue stage and/or augmentation of previously published award criteria without changing their fundamental intent.
