FAQs
Roof Windows in Lewes: FAQs
Do you provide roof windows across all of Lewes?

Is "Velux" the only brand of roof window you fit?
Velux is the best-known brand and the term people commonly use for any pitched roof window, but we fit from a range of manufacturers depending on your budget and specification. We advise on the right product at survey.
Do roof windows need planning permission?
Most roof windows fall under permitted development, provided they don't project significantly beyond the roof plane and meet other standard criteria, but conservation areas and listed buildings can have additional restrictions. We confirm the position for your specific property before ordering.
How does South Downs National Park status affect building work in Lewes?
Development within the National Park is assessed with particular regard to landscape character and setting, alongside normal planning policy. Combined with the town's conservation area and listed building status, this means early advice is particularly valuable in Lewes.
