How to Quote and Run a Commercial Kitchen Fit-Out

What you will learn

• How to structure a site survey that captures utility connections, structural constraints, and programme requirements before you price a single line item.
• Why equipment lead times of 4-8 weeks for bespoke stainless steel items must drive your programme from the moment deposit is received.
• How to break a commercial kitchen quotation into five cost categories - equipment, fabrication, trades, compliance systems, and contingency - that prevent scope disputes.
• What compliance sign-offs are required before a commercial kitchen can legally operate: gas commissioning, ventilation testing, fire suppression, and EICs.
• How to sequence multi-trade installation so strip-out, first fix, wall finishes, equipment delivery, and ventilation commissioning happen in the right order.
• What to include in a handover pack and how to manage snagging formally to protect against post-handover warranty disputes.

A commercial kitchen fit-out is one of the most complex specialist trade projects a contractor can take on. Unlike a single-trade installation, it requires coordinating gas-safe engineers, electricians, plumbers, ventilation specialists, stainless steel fabricators, and catering equipment suppliers - often within a tight programme set by a hospitality client losing revenue every day the kitchen is offline. Projects in the UK range from around £30,000 for a compact café kitchen to £150,000 or more for a hotel or institutional operation. Getting the quote right, managing procurement across multiple long-lead suppliers, and delivering to compliance standards without delay requires a disciplined process from first site visit through to final handover.

Stage 1: Site Survey and Client Brief

Before any pricing begins, you need a thorough site survey. Commercial kitchen projects have a habit of uncovering structural, drainage, and utility constraints that are invisible from a desk. A brief that sounds straightforward can become significantly more complex once you assess the existing services.

1. Confirm the kitchen's intended use and daily covers. A 50-cover restaurant kitchen and a 200-cover school canteen have fundamentally different equipment, ventilation, and utility demands - even if the physical footprint looks similar.
2. Map existing utility connections: gas supply pressure and pipe diameter, electrical supply capacity and distribution board location, hot and cold water supply points, and drainage positions. Upgrading any of these is a significant cost that must be priced before you quote, not discovered during installation.
3. Check structural constraints: ceiling height for canopy hood clearance (minimum 2.5 metres to comply with ventilation standards), floor loading capacity for heavy cooking batteries, and structural wall positions that affect layout options.
4. Photograph and sketch the existing condition in detail before touching anything. Disputes about what was discovered on site are common in kitchen fit-out projects. A timestamped photographic record protects you if a client later disputes what was found.
5. Clarify the client's programme requirements. When does the space need to be operational? Work backwards from that date to establish whether your procurement, fabrication, and installation timeline is achievable before you accept the job.

Stage 2: Scope of Works and Quotation

Commercial kitchen fit-out quotes have five main cost categories. Pricing any one of them without the others produces a quote that will either lose you the job on headline price or cost you margin in delivery.

Equipment supply accounts for the largest share of most projects - typically 40-70% of total project value depending on kitchen complexity. This includes cooking ranges, combination ovens, refrigeration units, blast chillers, prep tables, and pass-through dishwashers. Get signed-off equipment specifications from the client or their kitchen designer before you price; quoting against unconfirmed specs means pricing a moving target.

Bespoke fabrication covers custom stainless steel items: extraction canopy hoods, wall cladding panels, preparation benches, and under-counter units. These items must be priced from a detailed drawing, not estimated. Fabricators will not hold quotations open indefinitely; check validity periods before including their numbers in your submission.

Trades work covers electrical first and second fix, gas pipework and appliance connection by a Gas Safe-registered engineer, plumbing and drainage, and ventilation ductwork installation. Labour and trades typically represent 15-25% of total project cost. Sub-contractor rates in this sector are set by specialist skill requirements; if you don't have established relationships, expect to pay full market rate for qualified engineers.

Compliance systems include the ventilation canopy and filtration system, fire suppression systems (mandatory above deep-fat fryers and solid fuel cooking equipment), grease management traps, and emergency gas isolation valves. A ventilation canopy installation typically costs £2,000-£5,000; a fire suppression system adds a further £2,000-£7,500. These are non-negotiable line items and must never be removed from a quote on value-engineering grounds.

Contingency should be built into every quotation at 10-15% of total project value, particularly for refurbishment projects where concealed conditions are unknown. State this explicitly in your quote breakdown so the client understands what it covers.

1. Obtain a signed-off equipment schedule from the client or their kitchen designer before pricing. A schedule of equipment that someone has formally approved is the document that makes your quote accurate and defensible.
2. Obtain fixed quotations from your stainless steel fabricator for all bespoke items. Never estimate custom fabrication work - the margin for error is too wide.
3. Break your quote into the five categories above with clear line-item costs. A single "kitchen fit-out" headline number invites the client to ask for reductions without understanding what they are cutting; a detailed schedule of works shows what you are delivering and why each element costs what it costs.
4. State all exclusions explicitly: structural works, flooring, decoration, client-supplied equipment not covered by your installation scope, and items requiring specialist sign-off outside your trade scope.
5. State lead times for long-lead items prominently in the quotation document. If a client accepts your quote without acknowledging lead times, the programme conversation happens on day one of the job rather than during negotiation.

Stage 3: Procurement and Programme Planning

Once a quote is accepted and a deposit received, the programme must be built before any orders are placed. In a multi-trade, multi-supplier project, the sequence in which things arrive on site determines whether installation runs smoothly or stalls at every handover point.

Equipment lead times drive the programme. Standard commercial catering equipment typically carries a 3-6 week lead time. Bespoke stainless steel fabrication requires 4-8 weeks from design approval to delivery. If you place orders before the kitchen layout is finalised and signed off, you risk ordering to a scheme that the client subsequently changes - and your fabricator may not accept returns or modifications on custom work without cost.

1. Issue purchase orders for all equipment and fabrication items within five working days of deposit receipt and layout sign-off. Late ordering is the most common cause of programme overruns on kitchen fit-out projects.
2. Confirm sub-contractor bookings for all required trades: Gas Safe engineer, electrician, plumber, and ventilation engineer. Book against your programme dates, not against when you estimate you will need them - certified tradespeople are in demand and cannot always hold availability.
3. Build a programme showing the sequence of activities in order of dependency: structural preparation and first fix before equipment delivery, drainage before screeding, electrical first fix before ceiling, ventilation ductwork before canopy commissioning, equipment installation after the building envelope is complete.
4. Share the programme with the client and confirm their responsibilities: access arrangements, outstanding specification decisions, and client-supplied equipment delivery dates that fall within your installation window.

Stage 4: Installation and Trades Management

Kitchen fit-out installation requires trades to work in a defined sequence. Deviating from that sequence - typically because a sub-contractor becomes available earlier than planned - creates rework and additional cost.

1. Strip-out and structural preparation. Clear the existing space, carry out any structural works, and prepare drainage and floor penetrations. Any concealed surprises - asbestos, undersized gas supply, structural elements in unexpected positions - must be identified at this stage, not after equipment is ordered.
2. First-fix services. Electrical conduits and trunking, gas pipework rough-in, water supply and drainage connections. All services should be routed to the equipment positions defined in the approved layout drawing. If the layout changes after first fix is complete, the cost is yours unless the change was requested and agreed in writing by the client first.
3. Wall cladding, hygienic wall finishes, and flooring. Anti-slip flooring and hygienic wall cladding go in before equipment is installed to avoid surface damage during delivery and to allow sealant runs to be made correctly around installed items.
4. Equipment delivery and positioning. Coordinate delivery to avoid access congestion. Heavy commercial catering equipment often requires two people and a sack truck through doorways not designed for commercial kit. Measure doorways and service corridors against equipment dimensions before booking delivery.
5. Canopy and ventilation installation. The extraction canopy must be fixed, connected to ductwork, and tested before gas and cooking equipment is commissioned. The ventilation interlock is a compliance requirement on gas appliances in commercial kitchens: if the extraction system is not operational, the appliance cannot be commissioned.
6. Second-fix services and equipment connection. Electrical final connections, gas appliance connection by your Gas Safe engineer, and water connections to equipment. Record any variation between the as-installed position and the approved layout drawing.

Stage 5: Compliance Testing and Commissioning

A commercial kitchen cannot legally operate until it clears several compliance requirements. These are not formalities - they are sign-offs that determine whether the kitchen opens on time.

Gas appliance commissioning must be carried out by a Gas Safe-registered engineer. Every gas appliance must be commissioned, tested for safe operation, and signed off with a gas safety record. Emergency gas isolation testing is included in this sign-off.

Ventilation testing confirms the extraction canopy achieves the required air change rates for the heat load generated by the cooking equipment below it. A busy restaurant kitchen generates 50-100 kilowatts of heat output; the extraction system must handle that load continuously or the kitchen will fail environmental health inspection.

Fire suppression commissioning applies to systems installed above deep-fat fryers and solid fuel ranges. The commissioning engineer issues a certificate that must be available for inspection.

Environmental health inspection is typically arranged by the client, but you will commonly be asked to provide supporting documentation in advance: gas safety certificates, electrical installation certificates, and evidence that ventilation systems meet Building Regulations requirements.

1. Arrange gas appliance commissioning through your Gas Safe engineer before handover. Do not hand over a kitchen with any gas appliance unconnected or uncommissioned.
2. Arrange ventilation testing and obtain a written report confirming extraction rates meet the required standard.
3. Complete Electrical Installation Certificates for all new electrical work carried out during the project.
4. Compile the full handover pack before the client walkthrough: gas safety certificates, Electrical Installation Certificates, ventilation test report, fire suppression commissioning certificate, equipment warranties, and manufacturer operation and maintenance manuals for all installed items.

Stage 6: Handover, Snagging, and Aftercare

The handover walkthrough is the formal moment when responsibility for the kitchen transfers to the client. Do not conduct this walkthrough without first completing your own pre-handover check.

1. Carry out a pre-handover snagging check before the client walkthrough. Test every piece of equipment for basic operation, check all sealant runs around equipment and wall cladding, and confirm every item on the schedule of equipment is installed and connected.
2. Conduct the client walkthrough with the client and their head chef or kitchen manager present. Walk through each zone of the kitchen and demonstrate operation of major equipment. Record any agreed snagging items in writing at the time of the walkthrough, not afterwards.
3. Issue the final invoice once the client has confirmed acceptance and the agreed snagging list is documented. Maintain a clear record of what snagging items were agreed at handover and when each was resolved.
4. Clarify warranty coverage in writing: distinguish between equipment manufacturer warranties (typically 1-2 years, handled by the manufacturer or their appointed service engineers) and your own workmanship warranty covering the installation itself.

A commercial kitchen fit-out run well comes down to doing the work in the right order: survey before you price, approved specifications before you order, first fix complete before equipment arrives, and compliance documented before handover. The projects that go wrong tend to do so at predictable points - underspecified quotes, late equipment orders, undocumented change requests, and missing commissioning certificates at handover. Follow the stages above and those predictable failures become manageable checkpoints instead.
