Frequently Asked Questions
How much do roof lanterns cost?
Typically between £2,500 and £6,000 installed, depending on size and specification.
Do roof lanterns need planning permission?
Most cases don't require it if they don't extend more than 150mm above the existing roof slope. Listed buildings may need approval.
Do they make a room too hot?
Modern systems use solar control glass and thermally broken frames to regulate temperature. We can specify blue or neutral solar control glass.
