How to Procure Kitchen Extraction Work Across Multiple Sites
Standardise the commercial process—not the technical conclusion.
A national restaurant, care, education, hotel or FM estate may want one contractor standard, one reporting format and one procurement process. That can improve control, but every kitchen still has its own extraction route, access conditions, operating hours, landlord interfaces and maintenance history. Strong multi-site procurement creates consistency around the information collected and returned without pretending every system is technically identical.
The estate needs consistency, but the buildings refuse to be identical.
A central property team may manage dozens or hundreds of kitchens under one brand, contract or FM arrangement. Procurement often begins by trying to create one national specification that can be sent to every supplier and every site.
The danger is over-standardisation. A drive-through restaurant, city-centre basement kitchen, care home, school, hotel banqueting kitchen and food-court unit may all have very different extract routes and access arrangements. A useful national programme therefore standardises the data fields, contractor checks, reporting expectations and exception workflow while allowing the appointed specialist to respond to the actual system at each location.
Do not start a national tender with only a list of addresses.
Site and kitchen identity
Record the premises, operator, relevant kitchen or outlet, local contact and any landlord or centre-management interface. Multi-kitchen sites should not be compressed into a single vague site record.
System information
Capture what is already known about the canopy, duct route, riser, fan, discharge, plant location and previous access limitations. Drawings and historic reports can materially improve the quality of the tender.
Maintenance history
Record latest inspection or clean, contractor, report date, known grease findings, previous exclusions and any recurring remedial recommendation.
Operating constraints
Trading hours, breakfast service, production windows, resident or patient occupancy, events, school terms, security and landlord access can all affect realistic attendance windows.
Professional trigger
Preserve any fire-risk action, insurer request, consultant recommendation, audit finding or internal maintenance requirement that explains why the site is in the programme.
Current status
Distinguish ready-to-quote sites from those that need missing information, access remediation, landlord coordination or another technical decision before procurement.
A national programme needs asset visibility and corporate memory.
HSE’s current maintenance, inspection and testing guidance highlights several principles that translate well into multi-site extract procurement: clear allocation of roles, a system for identifying relevant plant, competent people setting maintenance regimes, effective communication and a system to record, track and trend maintenance information.
HSE also says organisations outsourcing safety-related work should retain “intelligent customer” capability: enough understanding of the service being supplied to maintain oversight, coordinate outsourced activities and understand limitations and implications.
For an estate team, that means the contractor portal should not become the only place where the organisation understands its kitchen-extract assets. Core system information, outstanding exclusions and maintenance history should remain accessible to the client.
If the supplier changes, the estate should still know what systems exist, what was last done and which problems remain open.
Specify the minimum information and outcome—not a fictional identical system.
A national specification can set common expectations for contractor competence, reporting, photographs, access exclusions, escalation and document naming. It can also require the contractor to identify the actual system before work and state any site-specific variation.
What it should not do is assume every site has the same duct length, fan arrangement, access-panel provision, grease loading or safe working method. Those matters still need site-specific assessment by the appropriate competent contractor.
National coverage is only useful if quality and reporting stay controlled.
A single national supplier can simplify account management and reporting. A regional contractor panel can provide stronger local coverage or specialist capability. Either model can work if the estate maintains one commercial standard for contractor assurance, site information, evidence and escalation.
The procurement decision should consider more than map coverage. It should ask whether the supplier has sufficient resources, appropriately competent people, relevant VHR status where specified, consistent report quality, suitable subcontractor controls and the ability to manage exceptions rather than simply complete high volumes of routine visits.
Use the live register as a contractor-control tool, not as a substitute for the site scope.
BESA currently describes the Vent Hygiene Register as the UK’s official register for ventilation-hygiene contractors. Approved members can notify completed work, creating an auditable record, and the current scheme has separate Grease and Air categories.
For a multi-site Grease programme, an estate can specify current VHR Grease membership where appropriate and verify contractors through BESA’s live register. BESA’s current guidance recommends using the live contractor search because register status can change.
VHR can strengthen contractor assurance and evidence consistency. It does not tell the client whether a particular site has an inaccessible riser, a landlord-controlled roof or an incomplete technical scope.
The same programme can encounter very different sites.
The historic EC Cleaners archive spans QSR, care, education, hospitality and other environments. That range illustrates why multi-site procurement needs a common management framework without pretending that the technical systems and operating constraints are interchangeable.
These photographs are historic project context only. They are not current Search and Submit Ltd national framework contracts or evidence that one supplier model suits every estate.
A single unit rate can create false certainty.
National buyers often want one price per site. That is attractive administratively but can become misleading where systems vary materially in size, access, working hours or complexity.
A better model may combine standard price bands with clearly defined variation triggers. The supplier can then quote routine sites consistently while escalating genuinely different systems before attendance rather than recovering cost through exclusions or unplanned variations.
“Completed” is too weak a status for national estate control.
A contractor may have attended and invoiced a site while an inaccessible duct section remains unresolved. If the CAFM or procurement dashboard records only “complete”, the central team loses the exception that matters.
Use a status model that distinguishes physical attendance from evidential and remedial close-out. This enables the estate team to focus management effort on the minority of sites that need further action.
Do not reward volume if the same exclusions keep coming back.
Contractor KPIs should distinguish throughput from effective close-out. A supplier may achieve a high attendance rate while repeatedly recording inaccessible risers, late reports or missing evidence.
Useful programme measures focus on whether sites are progressing towards a maintainable, evidenced condition rather than simply how many visits were completed in the month.
EC can help create the commercial control layer between the estate and specialist contractors.
EC Cleaners Network can organise customer-supplied site information, create a consistent requirement structure, identify missing data, support contractor comparison, help verify public VHR status where relevant, coordinate regional specialist capability and keep returned evidence and exceptions visible.
EC does not inspect every system, set technical cleaning intervals, determine TR19 compliance, approve contractor technical methods or decide site-specific remedial engineering. Those responsibilities remain with the appropriate competent contractors and professional advisers.
Send the estate list and the information you already hold.
Include site addresses, kitchen/system data, current contractors, previous reports, fire-risk or insurer actions and known access problems. EC can help turn that information into a more controlled procurement programme and identify where the estate needs better data before national pricing begins.
