Planning and building regulations for Watford
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 Watford 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 Watford
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 still need to clean self-cleaning glass?
Occasionally. It keeps the glass cleaner for longer, but heavy dirt and droppings still need a gentle rinse, especially in dry spells.

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.
How quickly can I get a roof lantern in Watford?
