Commercial Kitchen Lease & Utility Audit (Australia 2026)

You can change almost everything about a restaurant after you open. The menu, the fit-out, the equipment, even the chef. The one thing you cannot change is the building you signed a five-year lease on, and whether it can physically power, ventilate and drain the kitchen you need.

Most operators assess a site on the things they can see: the rent, the foot traffic, the frontage, the condition of the room. Almost none check the things that actually decide whether a commercial kitchen can be built there at all, which are the utilities hidden in the walls and under the floor. How much electrical capacity the tenancy has. Whether there is a gas main, and whether the landlord will allow a connection. Whether there is a viable path to run an exhaust duct to the roof. Whether the drainage and grease trap can be approved for the volume you intend to cook. These are not fit-out details. They are the difference between a workable kitchen and a five-year mistake.

There is a second layer to the trap in 2026, and it is the one operators expanding into South East Queensland for the 2032 build-out are walking straight into. The buildings themselves are changing. Across the country, new commercial buildings are being designed, leased and financed on the assumption that they will be all-electric, and the equipment decisions made today will either fit that direction or fight it for the length of the lease. This is the guide to checking a site properly before you commit, and to understanding why the energy your kitchen runs on has quietly become a property and finance question, not just a cooking one.

The Verdict Before the Detail

For operators about to sign on a Brisbane or South East Queensland site:

Commit to a tenancy without auditing its electrical capacity, gas position and exhaust path, and you can find after signing that the kitchen you planned cannot legally or physically be built there, with the rework landing on you.
Design a gas-heavy kitchen for a modern building with no gas main, and you face tens of thousands of dollars to bring a connection from the street, council delays during a busy construction period, or a full redesign with deposits already paid.
Specify a properly planned all-electric kitchen that the building can actually support, and you keep the option of a ventless exhaust in restricted spaces, lower the heat load on your air-conditioning, and protect the resale value of the fit-out as the built environment decarbonises.

None of this depends on predicting policy. It depends on reading the building you are about to be tied to for five years.

The Thirty-Thousand-Dollar Brick Wall

How a signed lease and a finished set of drawings can collide with a building that was never going to allow them.

Picture an established and successful restaurant group taking a prime tenancy in a new high-density development near one of the Brisbane venue precincts. The location is excellent, the rent works, and they commission a full set of kitchen drawings built around what has always worked for them: several high-output gas wok burners and a bank of gas tube fryers. Eight thousand dollars of design, ready to build.

The drawings go to the building manager for approval, and that is where the project stops. The building runs on a sustainability-linked lease and was constructed with no commercial gas main. There is no gas connection to the tenancy, and none is going to be installed. The operator is left with two expensive options. Pay to bring a commercial gas line in from the street, which means tens of thousands of dollars in civil works and council approvals, and an open-ended delay during a period when every trade in the city is booked. Or scrap the gas design entirely, forfeit the deposits already placed on gas equipment, and redesign the kitchen as all-electric under time pressure, with the opening date slipping either way.

The lost design fee and the equipment deposits are the visible cost. The expensive part is the delay. In the run-up to 2032, the difference between opening on schedule and opening a year late is not an inconvenience. It is a year of the trading window the whole expansion was built to capture. None of this was bad luck. The information that would have prevented it, that the building had no gas and would not get any, was available before the lease was signed and before a single line was drawn. Nobody asked.

Why Capable Operators Keep Walking Into This

The obvious question is how experienced, successful operators keep making this mistake, and the answer is structural rather than a matter of competence. Nobody in the leasing chain is paid to tell you what the building cannot do. The leasing agent is selling the location, the rent and the foot traffic. The landlord wants the tenancy filled. The designer draws the kitchen the operator asks for. Every party in the process is pulling toward a signed lease, and the constraints, the amperage ceiling, the missing gas main, the blocked exhaust path, are precisely the information that slows a deal down. So it goes unmentioned, not out of bad faith, but because no one whose job is to close the lease has a reason to raise it.

That leaves the operator as the only party with a real interest in surfacing the problems, and usually the only one without the technical knowledge to ask the right questions. The result is a deal that feels complete, a location that looks perfect, and a set of utility constraints that nobody put on the table. The operators who avoid the trap are not smarter than the ones who fall into it. They are the ones who treat the building's services as something to investigate deliberately, with the right people asking, before the lease quietly turns the building's limitations into the tenant's problem.

Before You Sign: The Utility Due Diligence Checklist

The single most valuable hour in any kitchen expansion is the one spent confirming what the building can actually support, before the lease is signed. This is the checklist that separates operators who open on time from operators who discover the constraints after they are contractually committed. Run every line, in writing, with the landlord and a suitably qualified tradesperson, before you commit.

Three-phase power. Is three-phase power available to the tenancy, and what is the maximum amperage the switchboard and supply can deliver? An all-electric kitchen lives or dies on this number.
Spare electrical capacity. Beyond what is already connected, how much headroom is there for the load you intend to add? Existing capacity on the board is not the same as available capacity.
Gas availability and permission. Is there a commercial gas main to the tenancy, and will the landlord and the building's lease framework permit a new or expanded gas connection at all?
Exhaust path. Is there a viable route to run a kitchen exhaust duct to the roof, with the roof access and penetrations that requires? In many towers and basement tenancies, there simply is not.
Ventless feasibility. If a ducted exhaust is not possible, is a ventless, or recirculating, hood permitted for the equipment you plan to run? This is only viable with the right kind of kitchen, which the next sections explain.
Drainage and grease trap. Can a grease trap of the required size be installed and approved for your cooking volume, and is there a trade waste approval pathway for the site?
Make-up air. Is there a way to bring in the replacement air that any exhaust system pulls out, without which the kitchen cannot perform?
Future expansion capacity. If the business grows, does the site have the electrical and services headroom to grow with it, or is today's lease also today's ceiling?

Every one of these is a question the building answers, not the tenant. A wrong answer found before signing changes which lease you take. The same wrong answer found after signing is a rework bill, a delayed opening, or a kitchen that can never quite do what you need.

Power: The New Bottleneck

The moment a kitchen moves away from gas, electricity stops being a background utility and becomes the constraint that governs everything. A serious all-electric kitchen running induction cooktops, electric fryers, combi ovens and refrigeration draws a large, concentrated electrical load, and that load is three-phase. A tenancy wired for a small cafe will not run it.

Three high-output induction units alone can draw enough current to overwhelm a modest switchboard before the fryers and ovens are even counted. This is why the power question has to be answered before the lease, not during the fit-out. An electrician needs to confirm not just that three-phase is present, but the actual amperage the board and the building's supply can deliver, and how much of that headroom is still free. Discovering a shortfall after committing means a switchboard upgrade, and sometimes a wait on the network provider to lift the supply to the building, both of which cost money and time the project plan never allowed for. Our guide to single-phase against three-phase power and switchboard capacity covers what to check and what an upgrade involves. This is also where the production side connects: a central production kitchen running combi ovens and blast chillers, covered in the scaling guide, multiplies the same electrical demand again.

Exhaust and the Ventless Question

The exhaust system is the other utility the building decides and the tenant lives with. A conventional commercial kitchen needs a ducted canopy that runs to the roof, governed in Australia by AS 1668.2 for the ventilation and AS 1668.1 for the fire-rating of the duct, with make-up air to replace what the hood extracts. In a standalone building this is routine. In a basement food court, a mid-level tenancy in a tower, or a heritage building with no clear duct route, it can be impossible or ruinously expensive to achieve.

This is where a ventless, or recirculating, hood becomes the only way to put a kitchen in the space at all. A ventless hood filters and recirculates the air rather than ducting it outside, which removes the need for a roof penetration. The catch is that ventless systems are only viable with a specific kind of kitchen: low-grease, low-heat, and almost always all-electric. Open gas flames and the combustion products they produce are not compatible with recirculating hoods, which is why a gas-heavy design forecloses the ventless option entirely. If the site has no exhaust path, the kitchen has to be electric and low-output before a ventless hood is even on the table. The energy decision and the exhaust decision turn out to be the same decision.

Drainage, Grease Traps and the Approval That Does Not Transfer

The least glamorous utility on the list quietly stops more fit-outs than operators expect. A commercial kitchen producing grease-laden wastewater has to discharge it through an approved grease trap, and that discharge needs a trade waste approval. In Brisbane and the surrounding council areas, that approval is administered by Queensland Urban Utilities under Queensland's water supply legislation, and it is not a formality. The grease trap has to be correctly sized for the cooking volume, and the utility can refuse approval if the site cannot support what is proposed.

There is a detail here that matters specifically at the lease stage, and it catches incoming tenants. A trade waste approval does not transfer with the premises. If you take over a tenancy, even one that was previously a food business, you have to apply for your own approval, and that application is assessed against your intended use and the site's capacity. Assuming the previous operator's grease trap and approval simply carry over is exactly the kind of assumption that surfaces as a problem after the lease is signed. Confirm the trade waste pathway, and the grease trap sizing, as part of the same due diligence as power and exhaust.

Why Gas Has Become a Lease, Finance and Resale Risk

Here is the part to state carefully, because it is easy to overstate and the detail matters. Queensland has not banned gas in commercial kitchens. Hotels, hospitals, stadiums and countless restaurants across the state run on it, and a new fit-out using gas where a gas main exists is entirely legal today. Anyone who tells you gas is outright banned in Brisbane is wrong.

What is true is that the buildings, the regulators in other states, and the lenders are all moving in one direction, and a five-year lease signed in 2026 runs straight through the middle of that shift. The clearest signals are interstate. In Victoria, government policy requires all new homes and commercial buildings, including commercial kitchens, to be built all-electric from 1 January 2027, with no gas connection permitted. The City of Sydney has approved planning controls requiring new large commercial buildings, hotels and serviced apartments to be all-electric from the same date, and even there, the telling detail is that food and beverage premises in those buildings may keep gas only where there is adequate electrical capacity for future electrification. The direction of travel is not subtle.

Queensland has not legislated the same requirements, and it is worth being precise about that. But the pressure arrives through the property market rather than the statute book. Developers and landlords in new high-density buildings are increasingly declining new gas connections for their own environmental and financing reasons. Green Lease provisions and sustainability-linked finance make a gas-heavy building harder to fund and to let. The operators on the other side of those leases inherit the consequence: a kitchen built around gas in a building heading toward all-electric is a kitchen whose lease, financing and future resale are all working quietly against it.

The Stranded Asset Problem

This is the consequence almost nobody prices in, and it is the one that turns an equipment decision into a balance-sheet decision. Commercial kitchen equipment is an asset. It has a resale value, and that value is part of what an operator recovers when they sell or transfer the business. Gas equipment is quietly losing that value.

Walk the scenario forward. An operator fits out with a substantial gas suite in 2026. A few years later, they go to sell the business or assign the lease. The incoming buyer is looking at the same building stock everyone else is, where new and refurbished premises increasingly expect all-electric. To that buyer, a gas wok suite and gas fryers are not an asset to pay for. They are equipment to remove and a kitchen to re-electrify. The gas gear does not just fail to add value. It becomes a line in the negotiation the buyer uses to discount the sale, because they are pricing in the cost of ripping it out. Equipment bought as an asset has turned into a remediation cost. The operator who specified for where the buildings were heading keeps that value. The one who specified for where they had been gives it away at the worst possible moment.

The Heat Nobody Budgets For: The HVAC Money Chain

Set the environmental argument aside completely, because there is a purely financial case for electric cooking that operators feel every month, and it runs through the air-conditioning bill. The argument is about waste heat.

A gas burner is an open flame, and a large share of the energy it burns never reaches the pan. Real-world thermal efficiency for commercial gas burners is often only around 40 to 50 per cent, with the rest going straight into the kitchen as waste heat. Commercial induction works the opposite way, transferring energy directly into the cookware through an electromagnetic field, with around 85 to 90 per cent reaching the pan and very little spilling into the room. In a Queensland kitchen, that difference is not academic.

Follow the chain. A gas line pours waste heat into the kitchen, driving the ambient temperature toward 40 to 45°C on a hot day. That heat carries three costs stacked on top of each other. It makes the kitchen punishing to work in, which feeds staff turnover in an industry already short of skilled people. It loads the air-conditioning, which has to fight all that extra heat, pushing up power bills every month the kitchen runs. And it forces the refrigeration to work harder in a hotter room, the exact problem covered in the Queensland climate guide. Electric cooking removes the heat at the source. The kitchen is cooler, the air-conditioning load drops, the power bill follows it down, and the refrigeration has an easier life. The environmental benefit is real, but the reason most operators do it is that it is cheaper to run, and the saving lands every month.

Can Induction Actually Replace a Gas Wok?

The objection that stops most Asian and high-heat kitchens from going electric is the wok, and it deserves a direct answer rather than a sales pitch. The old belief is that induction cannot deliver the ferocious, responsive heat a wok needs, and cannot produce wok hei, the seared, smoky character of properly fired wok cooking. That belief is out of date.

Modern commercial induction has a purpose-built answer in the concave induction wok station, a unit with a curved well that seats a round-bottomed wok and couples the electromagnetic field to it across the whole surface. These run at high power, commonly in the 5 to 8 kilowatt range and beyond, and they deliver something gas struggles to match: near-instant heat response and very fast recovery when cold ingredients hit the wok, with none of the ambient heat penalty of an open flame. Professional kitchens across Asia have already moved to induction wok cooking at scale. The searing intensity is there, the control is better, and the kitchen stays cooler. The wok is no longer the reason a kitchen has to stay on gas. It used to be the strongest argument for gas, and it has quietly become one of the better arguments for induction.

The All-Electric Replacement Matrix

For an operator translating a familiar gas line-up into an all-electric specification a modern building will support, the replacements are direct, and each one carries its own operational gain beyond simply removing the gas.

Traditional gas equipment	All-electric replacement	What you gain
Gas wok burners	Concave commercial induction wok stations, 5 to 8 kW and up	Fast heat recovery, no ambient heat, wok hei capable
Gas tube fryers	High-recovery three-phase electric fryers	Tight temperature control, lower kitchen heat load
Six-burner gas range	Heavy-duty commercial induction range	Precision, efficiency and easier cleaning
Gas salamander	Electric rise-and-fall or infrared salamander	Controllability and safety, no standing pilot

The point of the matrix is not that electric is simply newer. It is that each electric replacement removes a parcel of waste heat from the room, keeps the ventless and compliance options open, and holds its value in a building stock that is moving the same way.

Questions Operators Actually Ask

Are new commercial kitchens in Brisbane allowed to use gas?

Yes, gas is not banned in Queensland, and many kitchens run on it. But it depends on the building. A growing number of new high-density developments and sustainability-linked buildings are declining new gas connections, so whether you can use gas is decided by the specific tenancy, not by a blanket rule. Always confirm the gas position of a site before you design around it.

What is the biggest hidden cost of going all-electric?

Insufficient three-phase power capacity. A full electric kitchen draws a large, concentrated load, and many tenancies do not have the amperage headroom for it. This has to be audited before you sign the lease, because upgrading a switchboard or lifting the building's supply after the fit-out has started is expensive and slow.

Can commercial induction really replace gas woks for serious cooking?

Yes. Concave induction wok stations running at 5 to 8 kilowatts and above deliver the heat intensity and fast recovery wok cooking needs, with far less waste heat in the kitchen. Many professional kitchens have already made the change without losing searing performance or wok hei.

Why is gas equipment becoming a resale risk?

As more buildings move to all-electric, a buyer taking over a business in a gas-equipped kitchen increasingly sees that equipment as something to remove and replace rather than pay for. That turns a gas suite from an asset into a remediation cost, which buyers use to discount the sale. Electric equipment is more likely to hold its value as the building stock changes.

Does a previous tenant's grease trap and approval carry over to me?

No. A trade waste approval does not transfer with the premises. If you take over a tenancy, you have to apply for your own approval, assessed against your intended use and the site's capacity. Confirm the grease trap sizing and the trade waste pathway as part of your pre-lease checks, not after.

What is a ventless hood, and when can I use one?

A ventless, or recirculating, hood filters and recirculates kitchen air instead of ducting it to the roof, which lets you put a kitchen in a space with no exhaust path. It is only viable with low-grease, low-heat, and almost always all-electric equipment. Gas appliances are generally not compatible with ventless hoods, so the option depends on going electric.

The Trilogy Close: KW's Pre-Lease Utility Audit

This is the third of three firewalls for any operator scaling into South East Queensland ahead of 2032, and together they form a single piece of due diligence. The first is climate: your equipment has to survive Queensland's real heat and humidity. The second is scale: your production system has to carry volume legally and profitably. This, the third, is the building itself: your kitchen has to be one the site can actually power, ventilate, drain and finance, and one that holds its value as the built environment changes. The operators who treat climate, production and utilities as one connected question are the ones who win the contracts and keep the assets. Everyone else retrofits at the worst possible time.

KW Commercial Kitchen operates from a Sydney base with Australia-wide delivery, and supplies the heavy-duty induction, electric and combi equipment a modern, future-proof kitchen is built on. Before you sign a lease or approve drawings for any Brisbane or South East Queensland site, we run a Pre-Lease Utility Audit against what the building can actually support:

Available three-phase power and amperage headroom
Gas position and the realistic cost of any change
Exhaust path and ventless hood feasibility
Drainage, grease trap sizing and trade waste pathway
Equipment specified for performance and for future compliance
Integration with the climate and production requirements from the first two guides

We then supply and deliver the right equipment on the schedule your build demands, anywhere in Australia, so the project stays on time and the kitchen stays workable for the length of the lease. The cheapest fix to a utility problem is the one made before the lease is signed. After that, every option costs more.
