Tell us about the room, roof or repair
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.
Information that helps an installer quote
- Your postcode, the room to be lit and its approximate size.
- Whether the roof is pitched or flat, tiled or slated, if known.
- The approximate roof-to-ceiling distance and any known loft obstructions.
- For replacements or repairs, the existing make, age and symptoms if known.
- Access restrictions, property height, planned roofing work and your preferred timing.
Photographs can help a firm give an initial indication. Take them from a safe position; a site visit may still be needed to measure the route and inspect the roof. You do not need to remove a diffuser or enter an unboarded loft to complete the form.
Indicative UK sun tunnel costs
These are budgeting ranges from our service guide, not guaranteed quotations. The six main rows reproduce the figures in our service listings. They describe different project types and should not be added together. A straightforward job may sit near the lower end; difficult access, premium products or additional repairs can take it above the range.

Material-only prices and installation prices are different. The Checkatrade cost guide discusses kit, labour and access separately. Our figures are broad allowances for comparing the site’s services, rather than a fixed tariff. Confirm VAT, scaffolding, waste removal and making-good in each written offer. For extension sections, compare the length and diameter: MyJobQuote’s cost guide gives a £60–£165 supply-only range. The small maintenance allowance is for a simple accessible job; a roof fault or unavailable part may need a different scope.
What changes the price?
Tube diameter, length and the number of bends affect materials and fitting time. A flat roof needs a collector and weatherproofing detail suited to that roof system. Roof height, fragile surfaces and restricted access can require scaffolding or other protection. Rotten timber, damaged tiles, damp insulation and repairs to the ceiling are additional work unless included. Local labour rates and the number of units also matter.
Compare the proposed result as well as the total
- The manufacturer, tube type and diameter, with the proposed route and any elbows or extensions.
- The correct roof collector and flashing for tiles, slates or the flat roof covering.
- How insulation, tube seals and the ceiling air seal will be handled.
- Safe roof access, waste removal, ceiling repairs and decorating, with exclusions stated.
- Whether VAT is included, payment stages, a realistic start date and written warranty terms.
Ask why the proposed tube type suits the route and what daylight you can reasonably expect. A cheaper flexible kit may be poor value on an unsuitable long run. A like-for-like replacement may be enough where the current tube is sound, while repeated condensation needs diagnosis before another diffuser is fitted.
Permissions and safe fitting
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.
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
Will I receive four sun tunnel quotes?
You may receive up to four quotations. The number depends on the work, location and availability of suitable independent installers.
Can I get a firm price from photographs?
Photos may support an initial estimate, but a firm may need to inspect the roof, measure the tube route and confirm access before giving a written quotation.
Is there a charge to send an enquiry?
The homeowner enquiry is free and there is no obligation to accept a quotation. Agree any separate survey or diagnostic charge with the installer before booking.
