What is flexible sun tunnel installation?
A flexible sun tunnel uses a reflective concertina tube between the roof collector and ceiling diffuser. It can suit a short route with a modest offset, where a rigid assembly is difficult to position. The flexible tube must still be supported and fitted within its manufacturer’s length and bend limits.
Signs you may need flexible sun tunnel installation
- A small hallway has a short roof-to-ceiling distance.
- Minor loft obstructions make a straight connection awkward.
- You want to compare a lower-cost flexible option with a rigid system.
What a specialist may do
- Check the measured route against the product’s limits and assess likely daylight.
- Plan gentle curves around obstructions without crushing the tube or using unnecessary length.
- Fit the roof collector with flashing made for the roof covering.
- Attach and support the tube at both ends using the specified connections and seals.
- Reinstate insulation, seal the ceiling fitting and remove installation debris.
Details worth discussing
The corrugated lining and bends generally transmit less light than an equivalent smooth rigid route. A flexible system is not a solution for every long or complicated loft run. Compare the likely result as well as the initial cost.
Costs and the written specification
The indicative UK range for flexible sun tunnel installation is £400–£950. Treat this as a guide for one unit or agreed repair, not a guaranteed price. Tube length, parts, roof condition, property height and safe access can change the total. Confirm VAT, waste removal and ceiling finishing, and ask the firm to list anything excluded.
Roof work and approvals
A roof opening needs careful attention to structure, weatherproofing and insulation. Planning permission and building control requirements depend on the building, proposed changes and the rules in your part of the UK. Listed buildings and protected areas need particular care. Ask your installer what approvals apply before work starts; do not assume a small opening is automatically exempt. The Planning Portal is a starting point for guidance in England, with local authorities able to advise on your property.

The installer surveys the property, gives its own price and carries out the work; your contract is with that business.
Frequently asked questions
Is a flexible tube suitable for a long loft route?
Not necessarily. Flexible tubes have product-specific length limits and lose light through bends and their corrugated lining. Ask an installer whether a rigid system would perform better for the measured route.
What should I include in my enquiry?
Describe the room or fault, your roof type if known and any access restrictions. For flexible sun tunnel installation, clear details help the installer decide what needs measuring or inspecting before a written quote.
