They are a revolutionary new way of bringing sunlight – and the natural light spectrum – into a space without needing to cut a hole in your ceiling or walls.

Factors affecting cost of sun tunnel

  • Type of tunnel and roof panel you will choose: Flexible tunnels may be more expensive than rigid tunnels, but they have the advantage of being easier to install.
  • Diameter of the tube: The diameter of the tube installed will depend on the size of the room or stairway, and the associated cost can vary based on the diameter. Generally, the cost of a 10-inch tube will be less than that for a wider option.
  • Length of the tunnel: The longer tunnels, the higher the price and this would depend on whether the tunnel runs from the roof to the second or first floor. Accordingly, the sun tunnel cost can vary.
  • Ease of installation: Some sun tunnels do not run in a straight line from roof to ceiling, so flexible tubes are often used. They can be fitted around obstacles in the loft to let in light. Unfortunately, these do not let in as much light as rigid tubes and can be more costly to install.
  • Property location: The cost of a sun tunnel installation varies by region. In general, living in an urban area with high costs of living will lead to higher costs due to increased wages and overhead.
