Planning and building regulations for Harrow
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 Harrow 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 Harrow
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.
What is the smallest roof lantern?
Many ranges start at around 800–1000 mm. Below that, a flat rooflight is usually the better product.
Do I need planning permission for a roof lantern in Harrow?
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.
Is it worth having solar-control glass in Harrow?
With the midsummer sun about 61.9° high at noon, roof glass in Harrow gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
