Planning and building regulations in South Glamorgan
Rooflight energy standards in Wales come from the Welsh Approved Document L (2022), so check figures quoted for England do not get used by mistake.
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.

Self-cleaning glass roof lanterns in South Glamorgan: questions
Is self-cleaning glass the same as solar-control glass?
No. Self-cleaning is a coating that sheds dirt; solar control reduces heat gain. Many lantern units combine both.
Does it work under trees?
Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.
Can the coating be damaged?
Yes, by abrasive cleaning, some chemicals and silicone. Follow the care instructions supplied with your lantern.
Who checks building regulations for a lantern in South Glamorgan?
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.
