What is rigid sun tunnel installation?
Rigid sun tunnels use smooth reflective aluminium sections to carry daylight through the roof void. Straight sections, approved extensions and angled elbows allow a planned route to the ceiling. They are often chosen where light output matters or the route is longer than a short flexible connection.
Signs you may need rigid sun tunnel installation
- A deeper loft needs a carefully specified tube run.
- An existing flexible system provides disappointing daylight.
- A larger landing or room needs an assessment of tube diameter and output.
What a specialist may do
- Measure the full route and compare it with the chosen manufacturer’s permitted lengths.
- Plan the fewest practical bends without cutting or weakening roof timbers.
- Specify tube sections, extensions, elbows and compatible roof flashing.
- Secure the assembly and seal each joint without damaging the reflective lining.
- Maintain insulation continuity and fit the ceiling diffuser with a sound air seal.
Details worth discussing
A rigid tube is not a promise of a particular brightness. Tube length, bends, diameter, roof orientation and shading still matter. Ask the installer to explain expected performance for your route rather than selecting on price alone.
Costs and the written specification
The indicative UK range for rigid sun tunnel installation is £650–£1,800. 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.
Find a suitable independent installer
Sun-Tunnel.co.uk is a homeowner matching service. Send one online enquiry and you may receive up to four quotations from independent local sun tunnel specialists. The number depends on your postcode, the work requested and installer availability. There is no charge to request quotes and no obligation to accept one.
Companies joining the network are asked to provide relevant insurance details and references. Before appointing a firm, check its current cover, ask to see similar installations and agree the specification in writing. The installer surveys the property, gives its own price and carries out the work; your contract is with that business.
Frequently asked questions
Can a rigid sun tunnel have bends?
Yes, suitable systems use compatible angled elbows. Extra bends can reduce light transmission, so the route should stay as direct as the structure allows and follow the manufacturer’s limits.
What should I include in my enquiry?
Describe the room or fault, your roof type if known and any access restrictions. For rigid sun tunnel installation, clear details help the installer decide what needs measuring or inspecting before a written quote.
