Sun tunnels are typically more cost-effective than typical roof windows. However, before you buy a tunnel for your home you must consider the overall installation cost.
The sun tunnel itself can range between £300 and £1,000. This is dependent upon the brand, diameter and tubing length. The cost of installation can also vary, but it is always recommended that you employ a qualified tradesperson. The cost of installation can therefore be between £300 - £900.
You can therefore expect the cost of installing a sun tunnel to be between £600 and £1,900. This is again dependent on the exact sun tunnel you select and tradesperson you use.
