Planning and building regulations for Windsor
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.
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 Windsor 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 Windsor
Are small lanterns available quickly?
Standard small sizes are often available from stock. Lead times are confirmed on your quote.
Does a small lantern need an opening vent?
Not usually. Background ventilation for the room can come from trickle vents or extract fans. Vents are more useful on lanterns over kitchens and large living spaces.
Do I need planning permission for a roof lantern in Windsor?
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 Windsor?
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 SL4.
