A roof lantern is a great addition to any glazed extension, floods of natural light from above, with excellent thermal efficiency. It's a perfect way to modernise an existing conservatory or crown a new extension. But do you need planning permission for one?
In many cases, no. Most roof lantern installations fall within permitted development rights, meaning no planning application is needed. There are conditions, though. Height matters, the lantern must not raise the roof beyond permitted limits, and position matters too, with different rules applying near boundaries and on principal elevations.
There are exceptions worth knowing. If your home is listed, in a conservation area or has had its permitted development rights removed, you'll likely need permission. And separate from planning, building regulations still apply to the work itself, covering the structure, glazing and thermal performance.
It sounds more complicated than it is. In practice, the vast majority of our roof lantern installations proceed without a planning application, and where checks are needed, we guide you through them.
