Kitchen Remodel Costs & Rules in Australia (2025)

A useful kitchen budget starts with a defined scope and current local quotes. The same room can require very different work depending on whether you keep the layout, replace cabinetry, move services or alter walls. This guide keeps those decisions separate from the appearance shown in an AI concept.

Write the scope before asking for a price

Record what stays, what changes and what remains uncertain. Include cabinetry, benchtops, appliances, plumbing, gas, electrical work, ventilation, lighting, flooring, wall finishes, demolition and disposal. Mark any wall, service or concealed condition that still needs investigation.

Give each supplier or contractor the same scope and ask for an itemised quote. Record allowances, exclusions, tax, delivery, installation, approvals and the treatment of variations. A broad national price range cannot tell you what is included at your address.

Compare quotes on the same basis

• Scope: Check that each quote prices the same retained and replaced elements.
• Products: Record exact appliance, cabinet and surface specifications rather than relying on a category such as "premium".
• Site work: Identify demolition, access, protection, waste, service changes and any investigation.
• Responsibilities: State who measures, designs, orders, coordinates trades and supplies compliance documents.
• Programme: Ask for a project-specific sequence tied to approvals, selections and product lead times.

Agree a contingency from the actual uncertainties with the people who inspected the kitchen. This guide does not prescribe a universal percentage or construction duration.

Check approvals and regulated work locally

Building approval, strata or body-corporate consent, heritage requirements and trade licensing vary by jurisdiction and scope. Check with the relevant state or territory regulator, local authority and property rules before demolition. Ask each trade which licence, authorisation, inspection and certificate applies to the work they will perform.

Do not assume a cosmetic-looking change is unregulated if it affects walls, plumbing, gas, electrical work or ventilation. Keep the written advice and approvals with the project record.

Investigate materials before disturbing them

Older buildings can contain asbestos or other hazardous materials. If a material is unknown, stop before cutting, drilling, sanding or demolition and follow the assessment and removal process published by the regulator in your jurisdiction.

Australia's engineered-stone prohibition covers the manufacture, supply, processing and installation of defined engineered-stone benchtops, panels and slabs. Safe Work Australia also lists exclusions and controls for permitted work on legacy material. Confirm the selected product and work method with the supplier and installer; see Safe Work Australia's engineered-stone guidance.

Separate the cabinet layout from the finish preview

The kitchen cabinet layout guide lists the measurements and supplier information needed before ordering. AI Renovation's kitchen visualizer can explore an appearance from a photo, but it does not draw a measured cabinet plan, calculate clearances, locate services or confirm that an appliance fits.

1. Keep the original kitchen photo and list every fixed feature that should remain.
2. Use one visual question, such as a cabinet finish or broader style direction.
3. Compare the result with the original for changed openings, appliances and proportions.
4. Confirm real products with samples, specifications and supplier drawings.
5. Attach the concept to the written brief as an appearance reference only.

Prepare the project handoff

Before ordering or construction, assemble the agreed scope, checked measurements, current product specifications, itemised quote, approvals, responsibilities, programme and variation process. A generated image cannot validate compliance, price or buildability.
