Quick Answer
In Sydney, skylight installation typically ranges from around $800 for a fixed tube skylight to $4,000+ for an electric opening roof window, supplied and installed. Most homeowners adding a quality fixed or manual opening skylight budget $1,500 to $3,000 per skylight.

Cost by Skylight Type
Tube / Tubular Skylight
$800 - $1,500A compact reflective tube that channels daylight into hallways, bathrooms and smaller rooms. The most affordable option and quick to install.
Fixed Roof Window
A glazed fixed skylight that floods a room with natural light and offers a view of the sky. The go-to choice for living spaces and attic rooms where ventilation isn't required.
Opening / Electric & Solar Skylight
$2,500 - $4,000+A venting roof window that opens manually, by electric motor or solar control — adding fresh air and passive cooling as well as light. Rain sensors and blinds are popular add-ons.
Factors That Affect Cost
Two identical skylights can cost quite differently depending on:
Roof Type & Pitch
Tile, metal and flat roofs each need different flashing and detailing. Flat roofs often cost more to make watertight.
Shaft Length
A long light shaft through a ceiling cavity needs framing, insulation and plastering — more than a skylight sitting directly on an attic ceiling.
Glazing & Controls
Double glazing, tinting, electric or solar openers, rain sensors and blinds all add to the unit price.
Access & Number of Units
Difficult roof access adds labour, while installing several skylights at once reduces the cost per unit.
Skylights in Attic Conversions
Skylights are one of the most effective ways to make a sloped-ceiling attic feel bright and spacious, and they help satisfy the natural light and ventilation requirements for a legal attic bedroom. When skylights are installed as part of a full conversion, the shaft, lining and plastering are already covered in the project scope — so the per-skylight cost is usually lower than a standalone retrofit.
If you're planning a conversion, it's almost always better value to include skylights in the build rather than add them later. See our attic conversion cost guide for the full picture.
