Opening roof lanterns for Richmond homes
Electric opening vents to let warm air out at the highest point of the room.
In midsummer the noon sun stands about 62.0° high over Richmond, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Plan the power supply early
- Electric vents at the room's highest point
- Switch or remote control

Planning and building regulations for Richmond
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.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Richmond 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.

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 Richmond?
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.
