In Scotland, energy standards come from Section 6 of the domestic Technical Handbook, and most extensions need a building warrant before work starts.
Planning in Scotland follows the Scottish permitted development order; your council confirms whether your lantern needs consent.
Building regulations in Grangemouth are checked by your local authority building standards (verifier) service. Some like-for-like replacement work does not need a building warrant but must still meet the building standards. Your council's building standards service can confirm.

Questions from Grangemouth
What is the largest square lantern?
Ranges differ. Many go to around 3 m square, with extra hip bars on larger sizes. Tell us your kerb size and we will confirm which ranges can make it.
Will a square lantern leak at the top?
It should not when it is correctly installed and maintained. The apex is factory-designed to shed water; leaks usually come from the upstand or roof membrane rather than the lantern itself, which is why the upstand detail matters.
Who checks building regulations for a lantern in Grangemouth?
Your local authority building standards (verifier) service. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
