Velux & Rooflight Loft Conversions in London
If your loft already has enough head height, a rooflight conversion keeps the roof shape as it is and adds Velux windows. It is the quickest and lowest-cost loft conversion, and usually avoids planning permission.

Questions we're often asked
How much head height do I need?
As a rough guide, about 2.2 m from the top of the ceiling joists to the ridge. We measure this at the survey.
Does it need planning permission?
Usually not, as the roof shape doesn't change. Rooflights on the front of houses in conservation areas may need consent.
