What do sun tunnels & tubular skylights in Castle Douglas involve?
We handle sun tunnels & tubular skylights across Dumfries and Galloway, including Castle Douglas. In short: light pipes that bring daylight to halls and bathrooms with no window. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters. Think of sun tunnels & tubular skylights for windowless hallways, landings and bathrooms.
Neighbouring towns include Kirkcudbright (14 km) and Dumfries (25 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Castle Douglas
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.

Common questions
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
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.
Can it work at night?
Some models include a light fitting in the diffuser.
Will I need planning permission in Castle Douglas?
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas.
Is the survey in Castle Douglas free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
