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.
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 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
Which white matches uPVC windows?
Gloss white, often RAL 9016, is usually closest. Send us a photo of your windows if you are unsure.
Does a white lantern show dirt?
Outside, white shows dirt more than grey. Self-cleaning glass helps with the glass, and the frames benefit from an occasional wash.
Is it worth having solar-control glass in Windsor?
With the midsummer sun about 62.0° high at noon, roof glass in Windsor gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
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.
