Sun tunnels & tubular skylights for Helensburgh: the essentials
Our sun tunnels & tubular skylights service in Helensburgh covers light pipes that bring daylight to halls and bathrooms with no window. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Stone villas, cottages and conservation areas across Scotland often call for conservation rooflights in slate roofs. Think of sun tunnels & tubular skylights for windowless hallways, landings and bathrooms.
Helensburgh is the main town we list in Argyll and Bute; we also cover nearby Greenock and Gourock.
What you can choose
- Pitched or flat-roof flashings
- Insulated tube sections
- Diffusers in several sizes
- Ventilation adaptor
- Integrated electric light
- Low maintenance
- Rigid or flexible tubes for awkward lofts
Before you order: points to check
- Tube runs need insulation in cold lofts to limit condensation
- Light output falls with tube length and bends
Planning and building rules for Helensburgh
Scottish householder permitted development (Class 2B, other external alterations) can cover a rooflight that projects no more than 1 metre from the roof, but the right does not apply in conservation areas. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Scottish energy standards for glazing, including rooflights, use an area-weighted average of 1.4–1.6 W/m²K in extensions, so most modern units comply comfortably. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
See our building regulations guide for U-values, glazing limits and self-certification.

Sun tunnels & tubular skylights in Helensburgh: questions
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Do sun tunnels need planning permission?
Usually not on a house, provided the dome does not project too far and the property is not listed. Check if you live in a conservation area or a flat.
How much light does a sun tunnel give?
A good rigid tunnel on a bright day lights a hallway well. Output depends on tube diameter, length and the number of bends.
Is the survey in Helensburgh free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Helensburgh?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
