Planning and building regulations for Dartford
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Dartford 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 Dartford
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.
Do I need planning permission for a roof lantern in Dartford?
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.
How quickly can I get a roof lantern in Dartford?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for DA1.
