Outdoor Kitchens
Outdoor Kitchens near you
An outdoor kitchen is the most Australian of home additions and the one where the rules are least intuitive, because the thing that decides which rules apply is not the appliances. It is the roof and the walls around them. An appliance certified for outdoor use is safe outdoors; put the same appliance under a roof with the blinds down and you may have moved it indoors in the eyes of the gas rules.

Energy Safe Victoria's position on outdoor gas is direct: outdoor appliances should never be used inside, carbon monoxide is a silent killer, and it is odourless, colourless and can be fatal or cause serious long-term health conditions. Its gas installation guidance also makes the distinction explicit in the other direction: a barbecue can only be installed indoors if it has been certified to the domestic cooker standard AS/NZS 5263.1.1. So the question for any alfresco kitchen is which side of that line the space falls on, and it is a question to settle at design stage rather than at inspection.
Everything else follows from that. Gasfitting must be done by a licensed gasfitter, who must give you a compliance certificate on completion. Fixed electrical work must be done by a licensed electrician, who must give you a Certificate of Electrical Safety. Any plumbing to a sink is licensed work with its own paperwork. An outdoor kitchen is three regulated trades meeting in a bench, and the paperwork is how you prove it was done properly.
Is your alfresco area outdoors, or has it become indoors?
This is the decision the whole project turns on. Energy Safe Victoria's blunt rule for consumers is that outdoor appliances should never be used inside, and the risk it names is carbon monoxide, which it describes as a silent killer that is odourless and colourless and can be fatal or cause serious long-term health conditions. On the installation side, ESV's gas guidance states that barbecues can only be installed indoors if they have been certified to the domestic cooker standard AS/NZS 5263.1.1, and that flame failure devices apply to barbecues when they are certified to that standard or installed in caravans or boats.
The practical trap is the alfresco that becomes enclosed gradually: a roof goes on, then one side is built in for wind, then cafe blinds are added for winter. Each step is small and none feels like a change of category, but together they can turn an outdoor area into an enclosed one with an appliance in it that was never certified for the job. Ask a licensed gasfitter to assess the space as it will be used, including with the blinds down, before you buy the appliance.
Gas, ventilation and carbon monoxide in an outdoor kitchen
- Outdoor gas appliances should never be used inside, and ESV names carbon monoxide as a silent killer that is odourless and colourless.
- Gas appliances on balconies are required to have the flue terminal extend beyond the covered area and discharge towards the open side, though ESV notes this does not apply to barbecues and radiant gas heaters designed for outdoor use.
- A barbecue may only be installed indoors if it is certified to the domestic cooker standard AS/NZS 5263.1.1.
- LPG cylinders should only be used if they have been tested within the last ten years, and should sit on a firm, level base of non-combustible material.
- Never use a flame to find a gas leak; soapy water on the connections is the method ESV specifies.
- Insufficient ventilation is the hazard, so an enclosed alfresco with a gas appliance in it needs a gasfitter's assessment rather than an assumption.
What people actually build into an outdoor kitchen
- A built-in barbecue or grill, which is the element that raises the gas questions.
- A benchtop and cabinetry, which must be built for weather and for whatever the appliance manufacturer requires as clearance.
- A sink with hot or cold water, which brings plumbing licensing and a waste connection into the project.
- An outdoor fridge, which must be rated for outdoor use rather than an indoor unit moved outside.
- A pizza oven or solid fuel cooker, which introduces flue, clearance and bushfire considerations of its own.
- Power outlets and lighting, which must be suitable for the exposure and installed by a licensed electrician.
- Storage for a gas cylinder, which needs ventilation and a firm level non-combustible base.
The three licensed trades and the paperwork each one owes you
Energy Safe Victoria's advice on gasfitters is to always use a licensed gasfitter for any installation, repair or renovation involving gas work, to check their photo identification card and the registered classes shown on it, and to insist on a compliance certificate on completion, because that certificate protects you if a problem later arises from faulty installation. Accepting the work without one is not an option.
On the electrical side, ESV requires licensed electrical workers to give the customer a copy of the Certificate of Electrical Safety for electrical work. Prescribed work, which includes items like consumer mains and switchboards, cannot be turned on or left on until independently inspected by a Licensed Electrical Inspector; for non-prescribed work no inspection is required and the documentation must be provided within thirty days. Plumbing to a sink is licensed work too, with its own notices and certificates depending on the state.
Building a kitchen that survives being outside
- Cabinet carcasses in marine-grade materials, stainless steel or masonry rather than standard kitchen board.
- Benchtops chosen for UV stability as well as looks, since many indoor surfaces fade, chalk or crack outdoors.
- Fixings and hardware in a grade suited to the location, with coastal sites needing a higher specification again.
- Appliances specifically rated for outdoor use, including the fridge, rather than indoor models relocated.
- Electrical accessories with a weather rating appropriate to their exposure, specified by the electrician.
- Clearances to combustible materials as required by the appliance manufacturer, which vary between models.
- On bushfire prone land, materials and the treatment of the whole structure assessed before the design is settled.
Keeping an outdoor kitchen safe and working
- Check gas connections with soapy water at the start of each season, never with a flame.
- Confirm LPG cylinders are within their ten-year test period before refilling them.
- Keep the burner area and grease trays clean, since accumulated fat is the most common outdoor kitchen fire.
- Cover or protect the appliance when not in use, particularly through long wet or dusty periods.
- Have the gas appliance serviced by a licensed gasfitter on the manufacturer's recommended cycle.
- Check outdoor electrical accessories and their seals for water ingress and corrosion each year.
- Reassess ventilation if you add blinds, screens or walls, because the space may no longer be the one that was signed off.
Outdoor Kitchens: frequently asked questions
Can I put my barbecue under a roofed alfresco?
It depends on how enclosed the space is, and it is a question for a licensed gasfitter before you buy. Energy Safe Victoria's consumer rule is that outdoor appliances should never be used inside, and it names carbon monoxide — odourless, colourless and potentially fatal — as the hazard. Its gas guidance states a barbecue can only be installed indoors if it is certified to the domestic cooker standard AS/NZS 5263.1.1. Have the space assessed as it will actually be used, including with blinds down.
Who is allowed to connect the gas for an outdoor kitchen?
A licensed gasfitter, and nobody else. Energy Safe Victoria advises always using a licensed gasfitter for any installation, repair or renovation involving gas work, checking their photo identification card and the registered classes listed on it, and insisting on a compliance certificate at completion — your copy of that certificate protects you if a problem later arises from faulty installation. Every state licenses gasfitting, so check your own regulator's register.
What paperwork should I get when the outdoor kitchen is finished?
A gas compliance certificate from the gasfitter, a Certificate of Electrical Safety from the electrical contractor, and the plumbing certificate or notice your state requires for the sink connection. ESV's position is that a licensed electrical worker must provide a copy of the electrical certificate to the customer, with prescribed work also requiring inspection by a Licensed Electrical Inspector before it can be turned on, and non-prescribed work documented within thirty days.
Do I need a special fridge for an outdoor kitchen?
Yes. An indoor fridge placed outside is working in ambient temperatures, humidity and dust it was never designed for, and in many cases its enclosure and electrical components are not suited to the exposure either. Outdoor-rated units are built for it. The same principle applies to power outlets, light fittings and any other electrical accessory in the space, which should be specified by the licensed electrician for the exposure they will actually face.
Where should the LPG cylinder go?
In a ventilated position on a firm, level base of non-combustible material, as Energy Safe Victoria specifies, and only if the cylinder has been tested within the last ten years. A cylinder should not be enclosed in a sealed cabinet, since LP gas is heavier than air and will pool in a confined space if it leaks. If you want the cylinder hidden in joinery, have the gasfitter specify the ventilation for that enclosure rather than designing it first and asking afterwards.

What affects the cost of outdoor kitchen
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Size of the yard and the scope of the design
- Grading, excavation and drainage work
- Hardscape materials, such as stone, pavers or wood
- Plants, sod and soil
- Access for machinery
- Removal of old materials, trees or stumps
- How often visits are scheduled for ongoing services
How to compare outdoor kitchen builders before you hire
- Choose a company that does the kind of work you need, since design, lawn care, tree work and hardscaping are different specialties.
- For big projects, ask for a site plan or drawing before work starts.
- Ask how they'll handle grading and drainage so water moves away from the house.
- For tree removal or large pruning, look for a qualified arborist with liability insurance.
- For ongoing services like lawn care or snow removal, get the visit schedule and what's included in writing.
Questions to ask outdoor kitchen builders before you hire
- Can I see a plan or drawing before you start?
- How will you handle drainage and grading?
- Will you have underground utilities located before you dig?
- Does any of this work need a permit, such as for a retaining wall, fence or tree removal?
- What plants or materials do you recommend for our climate and my yard's sun and shade?
- Do you guarantee plants or sod, and for what conditions?
- Can you show me proof of liability insurance?
When to call a pro for outdoor kitchen
- Water that pools near the house or in the yard after rain
- A tree that is leaning, cracked or has large dead branches over the house or a driveway
- A retaining wall that is bulging, leaning or cracking
Outdoor kitchen permits and local rules
Some outdoor kitchen work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
