Questions from Speke
What happens if it rains while the vent is open?
With a rain sensor the vent closes automatically. Without one it stays where you left it, so a sensor is worth having.
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
Do I need planning permission for a roof lantern in Speke?
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.
Do you deliver roof lanterns to Speke?
Yes. Delivery to Speke (L24) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
