Planning and building regulations for London
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in London are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from London
Can the coating be damaged?
Yes, by abrasive cleaning, some chemicals and silicone. Follow the care instructions supplied with your lantern.
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.
Do I need planning permission for a roof lantern in London?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
Can you fit a roof lantern in London?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
