Flat rooflights for Dover homes
A single near-flat pane on an upstand: minimal, low and discreet.
At 51.13°N, Dover sees roughly 7h 53m of daylight in late December and 16h 34m in late June. A lantern faces the bright overhead sky all year, so it brings in useful light even on the short, grey days.
- Sized to your upstand
- Single glazed unit with a slight fall
- Fixed or electric opening versions

Planning and building regulations for Dover
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.
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 Dover 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 Dover
Are flat rooflights cheaper than lanterns?
Usually, size for size. They use one glass unit and a simple frame.
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.
Do I need planning permission for a roof lantern in Dover?
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 Dover?
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.
