Planning and building regulations for Windsor
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.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
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
Does it help in winter?
Solar control mainly limits summer heat. Winter heat loss is governed by the U-value, which depends on the glazing unit and frame.
Can blinds do the same job?
Internal blinds reduce glare but the heat is already inside the room. Glass that stops the heat at the roof is more effective.
Do you deliver roof lanterns to Windsor?
Yes. Delivery to Windsor (SL4) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
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.
