Skylights and Installation Pricing in Melbourne (2026 Cost Guide)

For most homeowners in the Melbourne CBD or inner suburbs like Richmond, Southbank, and Fitzroy, the search for natural light begins with one question: “How much for a skylight installation?” Understanding the cost of skylights and installation requires looking past the sticker price at Bunnings and understanding the total scope of works.

What Drives Skylight Costs?

In Melbourne VIC, your skylight pricing is determined by three factors: the size of the skylight, the materials cost, and the labour costs associated with your specific roof.

1. Your roof type drives cost + install


Whether you have a tiled roof, metal roof (such as Colorbond), or a flat roof, the roof’s role in cost is significant.


  • Metal Deck & Corrugated Roof: These require specialised waterproofing. While it's industry standard to use basic kits, we utilise a custom back flashing system manufactured by Belle Skylights. This involves hot-riveting to prevent the capillary effect and leaks.
  • Tiled Roofs: We use a combination of a VELUX flashing kit and custom side-wall flashing (200mm minimum) to ensure sarking and underlay integration is perfect .
  • Two-Storey Access: If you are in a St Kilda terrace or a Brunswick townhouse, two-storey access often requires scaffolding, edge protection, or fall protection.


2. Shaft Depth and Interior Finishing


The complexity of installation often hides inside your ceiling cavity



  • Flat Ceiling: A standard light shaft through a flat ceiling is straightforward. However, shaft depth matters; deep shafts require more framing, plastering, and sanding.
  • Cathedral Ceiling: If you have a cathedral ceiling, the install is more direct but requires precise deck mount or curb mount techniques.
  • Basements & Ground Floors: We specialise in bringing light to basements and ground floors using yellow tongues to feed cabling through ducted heating voids.


Illume vs. VELUX: What's the difference?

In short, the difference is a structural roof window and a high-tech skylight alternative.

The Illume (Solar-Powered LED)

Did you know?


5000K light is often called "daylight". It provides a bright, crisp, and cool white light that resembles natural sunlight.

Because it is a synthetic replication rather than a structural cutout, it eliminates common homeowner concerns like heat transfer, roof leaks, and the need for expensive light shafts.


The technology is sophisticated enough to mimic the behavior of a physical skylight by diminishing to approximately 75% intensity when clouds pass over, ensuring your interior mood changes naturally with the weather. For many Melbourne homeowners, this offers an energy-efficient and budget-friendly way to transform a dark kitchen or hallway in under two hours without the dust, painting and disruption of major renovations.

Illume Features

Replicates Natural Light

Runs at 5,000 Kelvin and mimics clouds by dropping to 75% intensity.

Pricing

Starts from $995 AUD

No Structural Risk

No light shaft required, meaning no membrane or sarking issues.

This option is perfect for you if you just want better lighting.

Illume Benefits

Natural light in impossible locations: illume brings the feeling of sunlight to ground-floor kitchens, basements, and internal hallways in Melbourne’s high-density townhouses where traditional structural skylights cannot reach

Superior thermal insulation for Victorian winters: By avoiding a physical roof cutout, illume prevents expensive heating from escaping in winter and blocks harsh heat from entering during Melbourne’s 40°C summer days

Rapid, dust-free transformation: While structural installs can take days, an illume system is typically installed in under two hours with no mess, framing, or plastering required

Fixed pricing with no surprise variations: City Skylights offers a written, fixed-price guarantee, ensuring the quote you receive is exactly what you pay regardless of installation difficulty

VELUX (Vlux)

Velux Features

Fixed Skylight

Perfect for daylighting without the need for airflow.

Electric Skylight

Features a built-in rain sensor, solar blind, and blockout blind.

Performance

Features Low-E glass and UV protection for superior thermal performance and reduced condensation.

Velux Benefits

Architectural and aesthetic appeal: VELUX units provide high-end architectural appeal by allowing you to see the sun and sky directly from your living space

Smart rain sensor technology: Remote controlled units feature built-in rain sensors that automatically close the roof window during inclement weather to prevent internal flooding

Worldwide industry leader: Every unit is manufactured by a Danish company with plants in Denmark and the US to ensure premium global quality standards

Professional site inspection: We provide a physical assessment of your roof line and trusses to ensure an accurate installation quote, unlike competitors who quote over the phone

Custom flashing for leak prevention: We use custom flashings for Colorbond and tile roofs that are hot-riveted to ensure a 100% watertight seal for the Melbourne climate.

Increased home value: Installing authentic structural skylights adds significant perceived value and premium daylighting quality to your primary residence or architectural project.

Frequently Asked Questions

Proud partners:

  • How much does it cost to install a skylight in Australia?

    The cost varies significantly depending on whether you choose a structural unit or a solar-powered alternative. At City Skylights, our illume single story installations start from $995. Structural VELUX installations involve higher costs due to the need for a light shaft, roof framing, and internal plastering.


    If you're after a Velux we will come out and give you a comprehensive in person quote.

  • Is it cheaper to put in a window or a skylight?

    In many cases, an illume skylight alternative is more cost-effective than a traditional wall window because it does not require structural changes to your external walls. For internal rooms, kitchens, or basements, a skylight provides direct overhead light that a standard window simply cannot deliver in high-density Melbourne living.

  • Do skylights add value to a home in Australia?

    Yes, skylights significantly increase the perceived value of a property by improving liveability and natural light levels. Buyers in the Melbourne market prioritize bright, open spaces, and adding light to a previously dark ground floor can transform the entire feel of a home.

  • Does Bunnings install skylights?

    Bunnings is a retail supplier and generally does not provide specialized installation services for complex roof types. While you can purchase DIY kits there, you only get a 12 month product warranty. City Skylights provides a professional end to end

    service, and provides you with a 5 year product warranty and a 10 year installation warranty. This is backed

    by a $20 million Public Liability Policy.

  • What is the most typical skylight problem?

    The most common issues are maintenance, water leaks and condensation, particularly on tin roofs. We eliminate these risks by using custom back flashings that start under the ridge cap, ensuring that water cannot penetrate even during heavy Melbourne storms.

  • Can you put a skylight on an existing roof?

    Absolutely, we specialize in retrofitting skylights into existing homes, including double and triple story properties. For homes where a structural shaft is impossible, our illume system can be installed in under two hours without any major construction work.

  • Do you need planning permission to put skylights on your roof?

    In most cases, standard skylight installations do not require planning permission as they fall under exempt development. However, if your project involves major structural changes or heritage overlays, we can provide guidance on compliance and building regulations during your free consultation.
