Flat rooflights for Bow homes
A single near-flat pane on an upstand: minimal, low and discreet.
In midsummer the noon sun stands about 61.9° high over Bow, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Fixed or electric opening versions
- Sized to your upstand
- Usually cheaper than a lantern

Planning and building regulations for Bow
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 Bow 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 Bow
Can a flat rooflight open?
Some ranges offer electric opening versions. Ask for availability for your size.

They should not, provided they are installed on a properly flashed upstand with the right fall and the seals are maintained.
Can you fit a roof lantern in Bow?
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.
Do I need planning permission for a roof lantern in Bow?
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.
