Engagement process description
L&Q are undertaking this preliminary market engagement (PME) to inform the design of a single procurement exercise comprising two separate Lots, with the intention of appointing one contractor per Lot.
Purpose of this PME
The purpose of this PME is to validate the proposed Lot-based procurement strategy; assess market capability, capacity, and readiness; and identify key risks, dependencies, and considerations associated with the safe and compliant delivery of ventilation servicing and maintenance. This PME is not intended to form part of any tender evaluation or selection process. Responses will be used solely to refine the procurement approach, specification, contractual framework and evaluation methodology prior to issuing the ITT.
Feedback received through this PME will be used solely to refine the procurement approach and will not be used to assess supplier eligibility or advantage in any subsequent tender process.
How will we set this out?
L&Q intends to undertake a single tender exercise structured into two technical Lots aligned to different ventilation system types. Each Lot will be awarded to a separate contractor. This approach is designed to align specialist capability with defined scopes of work, reduce delivery and compliance risk and support a diverse and competitive supply chain. The PME uses a structured Yes / No / Maybe response format, with light operational prompts included for context only.
