Do you need permission in Scotland?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
