Planning and building regulations in Gwynedd
In Wales, the Welsh Government's own Approved Document L applies, with limiting values that are not the same as England's.
Permitted development rules in Wales are set separately, so check with your council, especially for listed buildings and conservation areas.
Building regulations are checked by your local authority building control team. Replacing a rooflight in an existing home is building work in Wales too. A competent person scheme installer can self-certify; otherwise building control should be notified.

Triple glazed roof lanterns in Gwynedd: questions
Will triple glazing stop rain noise?
It reduces it noticeably. Laminated glass reduces it further.
Can I have triple glazing with solar control?
Yes. Triple units usually include a solar-control or neutral coating.
Do I need triple glazing to meet building regulations?
Not usually. Well-specified double glazed lanterns generally meet the limiting values for rooflights. Triple glazing is an upgrade, not normally a requirement. Your building control body can confirm for your project.
Who checks building regulations for a lantern in Gwynedd?
Your local authority building control team. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
