What to have ready
Nothing is essential, but these help us give you a quicker, firmer answer:
- a photo of the roof from the garden, and of the ceiling where the light should go;
- for a replacement, the label or size code on the old unit if you can see it (on a VELUX window it sits on the frame when the sash is open: a letter for the width and digits for the height);
- whether the house is listed, or in a conservation area, if you know.
