Planning and building regulations for Carshalton
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.
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 Carshalton 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 Carshalton
Will solar-control glass make the room dark?
It lets slightly less light through than clear glass, but a roof lantern admits so much daylight that most people do not notice the difference.
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 I need planning permission for a roof lantern in Carshalton?
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.
Can you fit a roof lantern in Carshalton?
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.
