Planning and building regulations for Hanworth
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 Hanworth 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 Hanworth
Do flat rooflights leak?
They should not, provided they are installed on a properly flashed upstand with the right fall and the seals are maintained.
Can I walk on a flat rooflight?
Only if it is a walk-on rooflight designed for foot traffic. Standard rooflights are not designed to be walked on.
Do I need planning permission for a roof lantern in Hanworth?
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.
Do you deliver roof lanterns to Hanworth?
Yes. Delivery to Hanworth (TW13) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
