Skylight Installation Costs: What to Expect in 2024

Skylights transform dark rooms, improve wellbeing, and reduce daytime lighting costs. Pricing varies by skylight type, glazing, roof integration, access, interior finishing, and electrical work. This 2024 Australian guide details costs for fixed, vented and tubular skylights, including Sydney‑specific considerations.

Skylight Types and Typical Costs

• Fixed skylights: $950–$2,400 installed (standard sizes, basic shafting).
• Vented skylights (manual/electric): $1,450–$3,800+ depending on controls and sensors.
• Tubular (Solatube style): $650–$1,600 installed; excellent for hallways and bathrooms.
• Custom units: $2,500–$8,000+ based on size and glazing.

Size, Glazing, and Frame Options

• Single vs double glazing: +$250–$650 premium for efficiency and condensation control.
• Low‑E and argon options add insulation and UV protection.
• Frames: aluminium (common), timber (premium), uPVC (thermal efficiency).

Installation Complexity

• Tile roofs: Additional flashing kits and tile adjustments; careful sarking and batten reinstatement.
• Metal roofs: Profile‑matched flashing kits; cut‑out and reinforcement as required.
• Flat roofs: Membrane tie‑ins and upstand curbs; waterproofing is critical.

Permits and Engineering

Most standard skylights are exempt or comply with simplified approval pathways; complex structural changes may require an engineer’s sign‑off and council notification. Always confirm local requirements.

Energy Savings and Benefits

Natural light reduces daytime lighting costs and improves comfort. Double glazing and blinds help manage heat gain in summer and retain warmth in winter.

Timeline

Single skylights are often installed in 1 day; complex/custom jobs run 2–3 days, including finishing.

Case Studies

• Inner West, Sydney: 2 tubular skylights with shafts—$2,280 installed.
