How we approach sun tunnels & tubular skylights in Grangemouth
Thinking about sun tunnels & tubular skylights in Grangemouth? The short answer: light pipes that bring daylight to halls and bathrooms with no window. The longer answer depends on your roof, which is why we survey before we price.
Stone villas, cottages and conservation areas across Scotland often call for conservation rooflights in slate roofs. Sun tunnels & tubular skylights suit small internal rooms where a full rooflight will not fit.
Grangemouth is around 18 km from Stirling, and we survey and fit throughout that part of the Forth Valley, including the FK3 district.
What you can choose
- Pitched or flat-roof flashings
- Insulated tube sections
- Diffusers in several sizes
- Rigid (brighter) or flexible tubes
- Integrated electric light
- Low maintenance
- Works on pitched and flat roofs
Things we check at survey
- Light output falls with tube length and bends
- Tube runs need insulation in cold lofts to limit condensation
Do you need permission in Grangemouth?
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed. 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 Grangemouth: questions
Can it work at night?
Some models include a light fitting in the diffuser.
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.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Do I need to be at home for the survey in Grangemouth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Grangemouth?
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas.
