Planning and building rules in Scotland
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed. Listed buildings need listed building consent where the work affects their character.
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.

- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
Will I need planning permission in Dundee and Angus?
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas.
